Working my way through some feedback and I have come across the following "issues":
1. Temperatures condusive to the formation of rain ice:
-7 to -25, or -30 to -40?
My theory is that at the higher of those two temp ranges, SCWD would be larger and therefore pose a greater icing risk. However answer given is -30 to -40. Obviously lower airframe temperature means more of the SCWD freezes on impact (thirty eightieths as opposed to seven eightieths). Is this the right tree to be barking up?
2. Triggers for a thunderstorm:
"convergence in a trough or a low", or "a steep ELR"?
I say steep ELR. Someone else says convergence. Both seem to be correct, but I would say the steep ELR is more correct than "convergence in a trough or a low", because convergence can still be associated with stability.
3. Setting QFE on final. Altimeter gives:
(A) height of the wheels above the RWY
(B) height of the static port above the AD datum
(C) height above AD elevation
I say (B). However answer given as correct is (A). ((D) was a crock of !!!!!e). Do I take it that all altimeters are corrected for the height difference between the static port and the bottom of the landing gear?
Thanks!
