And maybe another question which is right now a little bit a pain in my ass, where even after discussion with mechanics I came to no solution.
Which TWO instruments are adversely affected by an electrical power failure in flight?:
A. ASI
B. Magn. compass
C. DI
D. AI
E. CDI
A and b definitely not. I would have chosen c,d,e but the question said TWO, and now i am strungling. The discussion with the mechanics ended up that it's c and d, but also a cdi could be affected depending on an old or new one...
So hopefully someone here knows the right answer and can explain why.
Appreciate it, thx
