  The G5 electronic flight instrument delivers exceptional performance, reliability and ease of installation as a drop-in replacement for primary attitude and/or directional gyros in type-certificated fixed-wing aircraft. For select aircraft equipped with G500 or G500 TXi, G5 can also be used as a standby flight instrument to those systems. Providing an economical upgrade path via a comprehensive AML, the compact and cost-effective G5 is bringing modern “glass cockpit” reference to thousands of aircraft that would otherwise depend on older, vacuum-driven equipment.

  

  Affordable Glass Solution

  Designed for installation in FAR Part 23 Class 1 and Class 2 aircraft (singles and twins weighing less than 6,000 lbs), the 3.5” G5 display fits into a standard 3-1/8” round cutout, taking up just a fraction of the space and weight previously required by conventional gyro-based instruments. It’s valid for flight under VFR and IFR conditions. And, by combining visual cues and data readouts once scattered across a myriad of instruments, G5 makes flight information easier to scan — so pilots can respond more quickly and intuitively to any in-flight situation.

  Rock-solid Attitude Reference

  When configured as an attitude indicator, G5 uses solid-state AHRS reference to provide smooth, steady and reliable horizon-based pitch and roll indications. In addition to aircraft attitude, G5 will also support display of airspeed, altitude, vertical speed, slip/skid, turn rate, configurable V-speed references, barometric setting and selected altitude — as well as visual alerts upon arriving at a preselected altitude. A built-in GPS receiver provides highly accurate groundspeed and ground track readouts. Plus, a dedicated rotary knob on the unit allows for easy adjustments to altitude bugs and barometric pressure settings.

  Gain a Clearer Sense of Direction

  To provide even more situational awareness, G5 is also approved for installation as a replacement heading indicator/directional gyro (HI or DG) or horizontal situation indicator (HSI) in your panel. When paired with an affordable GMU 11 magnetometer, GAD™ 29 navigation data interface and select VHF NAV/COMMs or GPS navigators, G5 can serve as your primary reference source for magnetic heading, VOR/LOC guidance and/or GPS course guidance — as well as providing distance and groundspeed indications. The unit displays both vertical and lateral GPS/VOR/LOC course deviation when available. And you can use the G5 instrument’s rotary knob to easily make and adjust course selections — or to control heading bug settings in DG installations. For added system integration, a single magnetometer can supply heading information to two G5 units simultaneously. Additionally, G5 can provide heading output to select third-party autopilots (with GAD 29B).

  Experience an Innovative Autopilot System

  Reduce workload and fly with more confidence by pairing G5 with our GFC™ 500 digital autopilot¹ (sold separately). GFC 500 offers silky-smooth flight control and advanced, safety-enhancing capabilities at a cost-effective price never before available on certified aftermarket solutions for light, fixed-wing aircraft.

  Based on our revolutionary GFC 700 installed in thousands of new aircraft, GFC 500 offers Garmin ESP™ corrective technology, overspeed and underspeed protection, and a dedicated LVL button. Plus, it provides the ability to fly coupled GPS and IFR approaches with compatible Garmin navigators and NAV/COMMs as well as an optional go-around switch and automatic and manual electric trim.

  As part of the GFC 500 system, G5 provides input and display of attitude preselect, heading bug, vertical speed bug, airspeed target and flight director command bars, while a dedicated GMC 507 autopilot controller provides large dedicated keys, knobs and control wheel for mode, altitude, heading and vertical speed selection.

  Plus, in emergency engine power loss situations, pairing G5 with your GTN™ Xi navigator can enable Smart Glide™ functionality². When activated, Smart Glide finds and creates a Direct-to route to an airport estimated to be within glide range — or alerts you if no airport is estimated to be within glide range. When paired with your compatible Garmin autopilot (sold separately), Smart Glide automatically activates the autopilot’s IAS mode at best glide speed — using the GPS guidance to fly the aircraft near the selected airport — so you can resume control and land the aircraft.

  Dual Displays Double Your Options

  By installing dual G5 displays in your panel, you not only gain dedicated instruments for attitude reference and directional gyro/HSI guidance, but you also gain the advantages of backup redundancy with dual ADAHRS and reversionary display capability. In such installations, a secondary G5 can revert to display attitude information (consolidated with heading indication) in the unlikely event of a failure in the primary attitude indicator position. For added “get home” protection, each G5 display is available with a backup lithium-ion battery, which can provide up to 4 hours of emergency operation in case of an aircraft electrical outage or shutdown.

  Learn More About G5

  With supplemental type certification (STC) provided under an AML covering hundreds of certificated GA aircraft models, a G5 upgrade for your cockpit offers maximum capability and value for minimal downtime, paperwork and expense. You can select from an array of approved installation configurations incorporating single or dual G5 displays. And no matter which installation you choose, you’ll be flying with the peace of mind that comes with our industry-leading Garmin warranty backed by our No. 1-ranked product support team. See your authorized Garmin installation center for more details on the G5 glass upgrade for your aircraft.

• LPV Approaches, Priced for Your Aircraft

  • Slim, all-in-one touchscreen GPS navigator for Part 23 Class I/II aircraft (weighing less than 6,000 lbs) and experimental/amateur-built aircraft
  • Take advantage of WAAS GPS navigation with LPV approaches, which offer minimums as low as 200’ to greatly expand your operational capability
  • Pairs with select Garmin flight displays, or integrates directly with your existing course deviation indicator (CDI) for cost-effective installation¹
  • Visualize your entire flight plan, including departures, arrivals, instrument approaches, holding patterns and more on a rich, dynamic global moving map
  • Wirelessly transfer flight plans and stream weather, traffic, GPS position and backup attitude via built-in Connext® technology to the Garmin Pilot™ app and more

  Big capabilities come in a small package with the GPS 175 navigator. With its bright, clear high-resolution touchscreen display, you can have the advanced navigation functions you’ve always dreamed of. Entering flight information is a cinch, and accessing every function is fast and easy. It’s equally at home in certificated aircraft or an experimental aircraft. And it’s the same 2” height as older navigation equipment and can allow you to keep the legacy composite CDI already in your aircraft to minimize installation cost¹. That makes GPS 175 the smart, affordable way to add next-generation navigation to your favorite airplane.

  Perfect Touch

  The moment you power up GPS 175, you’ll see a familiar Garmin homepage on the 4.8” display, which puts the most important functions within only a few touches. Navigate to dedicated pages for the moving map, terrain, nearest airports, flight plan, procedures, waypoint information, utilities and more. With shortcuts available to the flight plan and Direct-to functions on almost every page, navigation features are usually just a tap away. Use your finger to pan and zoom on any map, traffic and terrain page. Enter waypoint data with the on-screen keyboard. And touch the home button to get you back to the main page at any time.

  For added control stability in flight, a shelf across the lower edge of the display serves to steady your hand in smooth and turbulent flight conditions. And if you prefer traditional controls, the concentric knobs provide yet another way to control many of the GPS 175 navigator’s functions.

  

  Intuitive Navigation

  With GPS 175, building and modifying flight plans is simple. As you enter waypoints, our FastFind feature automatically begins searching for the nearest identifier as soon as you start typing, so — in most situations — a press or 2 reveals just what you were thinking. You can also create holds, insert Victor airways and corresponding exit options, and add departures, arrivals and instrument/visual approach procedures. Additionally, you can edit your route using the map screen; a handy "rubber band" feature lets you grab any leg of your flight plan route  and move it to accommodate a deviation or ATC amendment to your flight plan.

  A variety of dynamically drawn and displayed maps provide situational awareness and context to the flight plan by highlighting visual reporting points, navaids, SafeTaxi® diagrams and hazards such as obstacles, power lines and terrain. Plus, the Smart Airspace™ feature automatically highlights airspace close to your current altitude and de-emphasizes airspace away from the current altitude. 

  

  Advanced Approach to IFR

  The SBAS/WAAS-certified GPS receiver can allow you to fly GPS-guided LPV glidepath instrument approaches down to as low as 200’, greatly expanding your operational capability. You can also access newer localizer performance (LP) and all area navigation (RNAV) approaches. Precise course deviation and roll steering outputs can be coupled to our GFC™ 500 and GFC 600 autopilots as well as select third-party autopilots so that IFR flight procedures such as holds, NextGen radius-to-fix (RF) legs and missed approaches may be flown automatically. In addition, the GPS 175 navigator lets you create and execute custom holding patterns over an existing waypoint or user-defined waypoint.

  Plus, when operating in VFR conditions, GPS 175 can provide advisory vertical approach guidance based on a published glidepath angle or a 3-degree approach glideslope from the runway threshold, while considering terrain and obstacle clearance. With this advisory guidance, you’re able to fly more consistent, precise vertical glidepaths into a variety of airfields.

  

  Add ADS-B Traffic and Weather

  When paired with dual-link Garmin ADS-B solutions, such as our GTX™ 345 series transponder or GDL® 88 universal access transceiver, GPS 175 can display ADS-B traffic targets as well as subscription-free ADS-B weather data in the U.S. Or you can opt for the GNX™ 375 navigator, which offers the same capabilities as GPS 175, but includes a transponder for ADS-B “Out” and “In.” The ADS-B weather link provides in-flight access to animated NEXRAD imagery, METARs, TAFs, winds and temperatures aloft, PIREPs, NOTAMs and more.

  When equipped with a compatible ADS-B solution, visual alerts help you recognize and avoid potential conflicts in busy airspace. Our patented TargetTrend^™ relative motion technology offers a faster, more intuitive way to judge the direction and closure rate of intruding targets in relation to your aircraft’s position. For example, if traffic is ahead of you and traveling along the same track but at a slower rate, the motion vector would point opposite of its indicated direction of flight to show you are overtaking the traffic. And, at the start or end of each flight, TerminalTraffic™^™ technology provides the most comprehensive picture of ADS-B equipped aircraft and ground vehicles in the airport environment. ADS-B equipped aircraft in-flight are easily distinguished from ground vehicles and taxiing aircraft, which are displayed using distinct colors and symbols. All information is presented on a simple, easy-to-understand SafeTaxi diagram with reference to runways, taxiways, hangar locations and more.

  

  Cockpit Integration

  The GPS 175 navigator interfaces with a variety of Garmin flight displays, including G3X Touch (experimental and certified), G5 (experimental and certified), G500/G600, G500 TXi/G600 TXi as well as select third-party displays¹. Plus, it’s also compatible with many legacy, composite-input based CDIs — allowing you to keep your existing CDI and have an easier, more cost-effective installation¹.

  And for even more work-saving convenience, you can use the built-in Connext technology to stream information between GPS 175 and compatible Garmin portables and mobile devices running the Garmin Pilot or FltPlan Go apps. You can create flight plans at home and upload them at the airport. And you can stream GPS data and backup attitude information (from the built-in AHRS) to your mobile device or Garmin portable, making them even more useful cockpit companions. Better still, you can also share ADS-B traffic and weather information if you’re equipped with a compatible ADS-B solution.

  Plus, our optional Flight Stream 510 installs in the memory card slot of GPS 175 to enable our Database Concierge database transfer and management capabilities via our Connext gateway. At home, you can download selected databases onto your mobile device by using the Garmin Pilot app. Then, once you get to the airport, Flight Stream 510 will automatically establish a wireless connection to the Garmin Pilot app and upload the databases from your device to your GPS 175 in minutes.

  • Advanced standby monitoring means you'll never miss an ATC call while listening to ATIS
  • Bright sunlight-readable display

  As compact as it is capable, the GNC 255 can bring powerful Nav/Comm capabilities to virtually any cockpit. Not only does the GNC 255 meet the basic needs of most pilots – including adhering to new airspace requirements in Europe – it also features a number of advanced features that save you time and effort. It also contains an internal VOR/LOC converter and 40-channel glideslope receiver.

  Choose Your Installation

  

  The GNC 255 is available in 2 versions to fit your needs. Each version comes with 25 kHz frequency channel spacing and 8.33 kHz channel spacing. The GNC 255 is available with either 10 W or 16 W of transmitter output, letting you find the right balance of power and price. It includes a 2-place intercom that’s ideal for 2-seat aircraft; no additional hardware is required to communicate with your passenger. It also contains an internal VOR/LOC converter and a 40 channel glidescope receiver. Plus, remote frequency flip-flop capability can help in demanding operating environments like helicopters, letting pilots keep their hands on the controls.

  Reduce Your Workload

  

  In addition to traditional Nav/Comm features, the GNC 255 incorporates a number of functions that can save you time and effort. Provide the GNC 255 with an airport or navaid identifier and it will automatically find all available frequencies (and vice versa) thanks to a built-in, updateable database. With a compatible GPS input, the device will find the nearest airport to your location and easily access its weather, center and FSS frequencies. You'll have the confidence to know you're talking to the right controller every time. The Nav/Comm's database technology also allows you to quickly pull up your most frequently or most recently used frequencies. The device even automatically decodes a station’s Morse code to provide a positive identification – no aural decoding required.

  

  The GNC 255 will provide distance, time and speed when installed with a compatible GPS source like our GTN or GNS series avionics. All information is displayed on a bright sunlight-readable display so you can quickly read it all at a glance. And when paired with a G500, G500H, G600 or G3X flight display, it allows for the display of VOR and ILS indications on the PFD and can follow autopilot commands. Alternatively, you can use an HSI or CDI like our MD200-306, which has been specifically designed to work with the GNC 255.

  Listen to 2 Frequencies with 1 Comm

  

  With the standby frequency-monitoring feature in the GNC 255, you won’t have to worry about missing an ATC call or other critical transmission. The GNC 255 allows you to listen to ATIS without leaving your assigned ATC channel. Swapping your active and standby frequencies is done with a single touch of a button. Pressing and holding frequency transfer key will automatically set the emergency frequency as your active radio. You can use the built-in timer to assist with approaches, holds and other assigned maneuvers.

  

  Need night vision?

  For pilots flying patrol aircraft or helicopters while using night vision goggles (NVGs) to aid visual surveillance, the GNC 255 series NAV/COMM radios are available in versions that offer NVG-compatible displays. Featuring readouts and lighting designed to suppress light waves in the red to near-infrared (NIR) spectrum, these radios screen out distracting light interference for NVG operations – while providing crisp, vivid display readability under all lighting conditions, from nighttime to bright daylight.

  Meeting ADS-B equipage rules for NextGen airspace just got easier — and more beneficial — for thousands of aircraft owners worldwide.

  With the introduction of the GTX 345 series of Mode S Extended Squitter (ES) transponders, Garmin provides a one-box, one-swap solution that enables owners and operators to meet ADS-B requirements with minimal expense, downtime and disruption to their panels — while providing all the weather and traffic benefits of ADS-B “In.”

  Your Transition to NextGen Made Simple

  The IFR-certified GTX 345 looks and operates like a standard Mode S transponder. It fits in the same 1.65-inch high slot in your avionics stack. It boasts a bright, sunlight-readable digital display, a pressure altitude readout, handy timers for approaches and other operations, plus dedicated pushbuttons numbered 0-9 for quick and easy squawk code entry. But where other transponders leave off, the GTX 345 is just getting started. The addition of 1090 MHz ADS-B “Out” transmission capability (using precise GPS-referenced positioning information) enables the transponder to automatically output the more accurate, more dynamic traffic surveillance data that the NextGen airspace system requires. For aircraft that may prefer or require a diversity solution, GTX 345 is available in a diversity configuration which utilizes two antennas — mounted on the top and bottom of the aircraft — to provide superior operational coverage. Plus, available ADS-B “In” reception unlocks even more capabilities for pilots, enabling them to display ADS-B traffic, weather and more on a variety of installed or portable displays.

  Your WAAS, Your Way

  The extra-precise GPS position reference needed to meet the traffic monitoring requirements of ADS-B can be provided either by the WAAS/SBAS-compliant navigation system that you may already have in your panel — or by an optional built-in GPS position source available with your GTX 345 transponder³. However your aircraft is currently equipped, the Garmin GTX 345 series offers a simple, minimally intrusive ADS-B solution to meet your needs. For even more flexibility, optional remote mount GTX versions are available for compatibility with the GTN™ 750/650 series of GPS/Comm/Nav systems, as well as select Garmin G1000® integrated flight deck systems — all of which provide built-in remote transponder code selection and control.

  

  See the Benefits of ADS-B “In”

  In addition to 1090 MHz ADS-B “Out”, the GTX 345 also makes available the subscription-free weather and traffic display capabilities enabled by ADS-B “In” — which can be interfaced with compatible cockpit displays or streamed wirelessly via Connext to our aera 796/795 and aera 660 series portables, as well as to tablets/mobile devices by way of the Garmin Pilot™, ForeFlight Mobile or FltPlan Go apps. The ADS-B weather link is continuously broadcast on the 978 MHz Universal Access Transceiver (UAT) frequency, and is similar to the basic services offered by leading commercial satellite weather providers. For example, you can access NEXRAD imagery, METARs, TAFs, winds and temperatures aloft, PIREPs, NOTAMs, and more1: Along with this, you can also receive ADS-B traffic position reports (and threat-level symbology) to help you see-and-avoid converging targets in busy airspace. Spoken audio alerts call out potential flight path conflicts (“Traffic, 10 O’Clock, same altitude, two miles”) to get you looking in the right direction. Meanwhile, on your display, Garmin’s patented TargetTrend™ relative motion display¹ offers a faster, more intuitive way of judging target trajectories and closure rates in relation to your flight path. As an added safety feature, available on most new Garmin products, our TerminalTraffic™ technology provides a comprehensive picture of ADS-B equipped aircraft and ground vehicles in the airport environment. ADS-B equipped aircraft in flight are easily distinguished from ground vehicles and taxiing aircraft, which are displayed using distinct colors and symbols. All of this information is presented on a simple, easy-to-understand SafeTaxi® diagram which references the location of runways, taxiways, hangar locations and more.

  Dual-link Completes the Picture

  The GTX 345 ADS-B receiver is a dual-link system. So, it can receive on both frequencies (978 MHz and 1090 MHz) authorized for ADS-B operations in the U.S. Not only does this provide the most complete traffic picture from aircraft transmitting on either frequency, but it also enhances your aircraft’s ability to access ADS-B transmissions and services from virtually anywhere. When integrating an active traffic system with the GTX 345, ADS-B traffic and active traffic targets are merged on the display to give pilots a truly comprehensive traffic picture.

  

  ADS-B for Your Integrated Flight Deck

  With a variety of compatibilities covering most fielded displays, our ADS-B enabled GTX series transponders offer the easiest NextGen upgrade path available from Garmin — especially for owners of select G1000-equipped aircraft. For these systems, a remote mount version, the GTX 345R, interfaces with either the aircraft’s existing WAAS position source for navigation or uses an optional built-in WAAS position source to meet ADS-B “Out” requirements. The G1000 series displays interface with the remote GTX transponder to provide onscreen squawk code entry and control in the conventional manner. Depending on the software version installed, your Garmin glass displays can also support subscription-free weather on the MFD — as well as ADS-B traffic targets on both the MFD and PFD displays for aircraft equipped with Synthetic Vision Technology (SVT™).

  

  Alerting and Altitude Encoding Made Simple

  For added situational awareness, the GTX 345 incorporates a built-in audio output for audible traffic and altitude alerts¹, which can be integrated into your existing audio panel. You can also pair the GTX series with an optional Garmin altitude encoder to satisfy data transmission requirements for IFR. As opposed to other transponders with altitude encoding built in, the Garmin altitude encoder mounts separately on the install rack. So, should the transponder ever require removal, there’s no need for the static line to be disconnected. Which, in turn, eliminates the need for a follow-on leak check — and thus helps minimize ongoing service costs.

  An easier path to NextGen

  The Garmin GTX 345 series is FAA and EASA approved for installation on hundreds of today’s most popular aircraft makes and models. For decades, Garmin has led in the development and deployment of ADS-B technology. And when you compare all the options available, it’s clear that Garmin is committed to making your transition to ADS-B operations as simple, economical and worry-free as possible.

  ¹Garmin ADS-B compatibilities cover a wide range of systems and displays; however, not all functions may be available for every configuration. Please check the Compatibility tab for more specifics or limitations that may apply to your system.

  ²AHRS may be disabled in rotorcraft installations, see your authorized Garmin dealer for more details.
