All four crew members were on the seats for arrival. It is not "policy" that I can remember seeing anywhere, but certainly convention.
Alf..
I said..
"PLI is a PFD representation of the pitch attitude where the stick shaker will occur"
You said...
"jtr I think that you have a common misunderstanding about the operation of the PLI."
and then went on to say...
"The principle of most systems (I do not know the 747 in detail) is to provide an indication of the stick shake angle of attack (AOA) on the attitude indicator."
Aren\'t we saying the same thing, or am I missing something?
