Yes, close enough!
Not many General Aviation aircraft have radar/radio altimeters.
Here are some details I found on the internet!
Fixed-Wing GA Aircraft (with Radar Altimeters as Standard)
- Cessna Citation X
- Cessna Citation Sovereign
- Cessna Citation Latitude
- Cessna Citation Longitude
- These business jets include the Garmin GRA 5500 radar altimeter as standard equipment (Flying Magazine, HeliHub.com).
Rotary-Wing GA (Helicopters) with Standard Radar Altimeters
-
AgustaWestland AW119Kx Koala
- Equipped with the FreeFlight RA-4500 radar altimeter as factory-standard (Helis.com).
-
AgustaWestland AW169
- Comes with dual radar altimeters integrated into its standard avionics suite (Wikipedia).
Summary Table
| Aircraft Type | Aircraft Models | Radar Altimeter Installed |
|---|---|---|
| Fixed-Wing (Business Jets) | Citation X, Sovereign, Latitude, Longitude | Garmin GRA 5500 (standard) |
| Rotary-Wing (Helicopters) | AW119Kx Koala | FreeFlight RA-4500 (standard) |
| Rotary-Wing (Helicopters) | AW169 | Dual radar altimeters (standard) |
Why These?
-
Garmin GRA 5500 for Fixed-Wing Jets:
Garmin’s first all-digital radar altimeter, offering high altitude accuracy and advanced reliability. It was selected as standard equipment in several Citation models (Flying Magazine, HeliHub.com). -
FreeFlight RA-4500 for Helicopters:
Specifically chosen by Finmeccanica (now Leonardo) as standard kit for the AW119Kx, integrating seamlessly into its avionics (Helis.com). -
AW169’s Dual Radar Altimeters:
This advanced rotorcraft includes dual radar altimeters as part of its sophisticated avionics suite (Wikipedia).
For Other GA Aircraft
Many GA aircraft (especially piston singles or turboprops) do not come with radar altimeters as standard. Instead, radar altimeters are commonly added via retrofit—particularly for operations requiring Part 135 or CAT II ILS capabilities (ICAO, Microsoft Flight Simulator Forums).
