Description
The AIR Avionics ACD-57 Altimeter Software License permanently unlocks the altimeter function and altitude display on your ACD-57 Air Control Display. This is a one-time digital license — no hardware required.
Why a Software License?
The ACD-57 is offered at a competitive base price by using a modular license model. This means standard users only pay for the functions they need, while those requiring advanced capabilities — like a certified primary altimeter — can unlock them separately. Licenses can be added at any time, even after installation and while the unit is already in service.
What This License Unlocks
- Fully ETSO-certified primary altimeter function
- Altitude display on the ACD-57 colour screen
- Usable standalone or in parallel with COM and/or transponder control

This is a digital license only. No physical item will be shipped. Compatible with the AIR Avionics ACD-57 Air Control Display (AA-ACD-57).
