ENGINE STALL WARNING UNIT FOR MIG SERIES AIRCRAFT
Replaces: PVS Stall Warning Unit
The unit is compatible to interface with DVS pressure transmitter that send stall pre-warning frequency signal to PVS unit that analysis / computes the signal and generates corresponding stall warning signal.
- Indigenous reliable design.
- Long operational life. No electro-mechanical components.
- Incorporates design for enhanced performance.
- Overcomes performance limitations and abnormality of Russian PVS Stall Warning Unit.
- Immune to disturbing signals. No false warning.
