Altimeter radar RA-5500

for aircraft

The RA-5500 retrofits aircraft that were never going to get a new panel. An analog output means it can replace another manufacturer's altimeter without touching the indicator it drives, while its digital interfaces serve modern fixed-wing and UAM platforms.

Keep the indicator, change the box
Aircraft still running legacy analog indicators are brought up to current standard without a panel programme. Existing antennas, indicators and cabling are retained.

One unit across a mixed fleet
The same part number serves aircraft on glass and aircraft on legacy indicators, so a fleet-wide upgrade does not become two separate programmes with two spares pools.

Sized for what comes next
At 1.30 lb (590 g) or less with low power draw, the RA-5500 fits the SWaP budgets UAM and advanced air mobility programmes are designed around.

Interference resilience
Customized RF filtering and digital signal processing mitigate C-band interference, guarding against erratic readings, autopilot disengagements and false terrain warnings. Units meet AD 2023-10-02 and AD 2023-11-07.

Approvals your installer can act on
Installation approvals, certificate numbers and installation contacts are published in the FreeFlight Systems STC library, so a shop can scope the job before the aircraft arrives.
