I=20 am using your question to answer two additional queries about AOA = systems that=20 I received during Oshkosh.

 

First=20 of all, AOA systems, when properly installed and calibrated, are a = great stall=20 warning system--better than the traditional vanes and airspeed-only = based=20 systems.

LOBO=20 has not endorsed any specific system, but strongly believes that any=20 properly-installed system, to include stall strips, are a significant = addition=20 to the airspeed indicator for stall warning and avoidance.

I am=20 considering adding AOA to my Legacy and was wondering if I can get = some=20 feedback from anyone who has done this.

 

Is=20 there any consensus out there as to what system is preferred, from a=20 performance standpoint and secondarily, ease of=20 installation.

 

I was=20 looking at the Alpha Systems DSTR-AOA-9000EK which just happens to be = named=20 Legacy.  

 

Any=20 experience about this or any other systems would be greatly=20 appreciated!

 

Thanks,
