I’ll probably get flamed and roasted to for saying this too:

 

AOA’s are important and angle of attack is the only thing that matters of course especially when flying slow but you need to have another skill if you are going to be a safe pilot in a Legacy (or any plane.):

 

You need to know what a stall feels like.  Raise your hand, how many of you have stalled your Legacy?  I suggest you do it as part of your training regimen.  If you need an instructor for this fine.

 

The fact is you only have about 2 seconds literally if you accidentally stall your machine to get the stick forward to prevent one of the wings from stalling and the plane from rolling.  If you don’t know what this feels like and don’t have a built in reflex to get the stick forward, you probably won’t survive a stall/roll below 2000 ft/agl.

 

(The advice to “just don’t accidentally stall your Legacy” ignores the reality of gear/canopy/engine/electrical problems in flight.  This happens over and over again – it is the leading cause of death in Legacies (sp?).)

I’ll probably get roasted, toasted and slammed for this but what the hell.

 

Sure and why don’t you just build and fly two airplanes in case one doesn’t work you have the other.  Sorry but I just couldn’t resist that.  For God’s sake man, how much redundancy do you really need?  If you’re really afraid of this happening maybe you shouldn’t be in aviation.  There are risks.  Accept a little and don’t worry about every little thing that can go wrong.

Subject: Pitot System and AOA

 

Greetings,

 

I will have an AOA in my Legacy. 

 

That said, I am concerned that if for some reason my pitot tube gets blocked by something like an insect, bird, or other debris, my airspeed indicator will probably be giving me an erroneous reading. 

 

Would not this error also be reflected in the AOA?

 

Therefore, would it not be a good idea to have the AOA on its own pitot source?  And could one tie both pitot tube together so that if one was blocked, the other would continue to provide pitot pressure?

 

Thank you in advance for your input.
