AS420 - Final Exam Flashcards Questions And
Correct Answers
Why is standardization important for a large airline? Why is standardization important
for a flight training operation such as at ERAU? - answer There will always be different
flight crews, and having a standardized flight deck ensures the safety and consistency
of each flight. ERAU has a young workforce
What are the four Ps and how do they affect your procedures and practices? Give an
example. - answer Philosophy, Policy, Procedures, Practices. Capt. Needs to be outside
cockpit, and F.O. does shutdown procedures
Why do airlines not use a generic manufacturer's POH as we do here with our Cessna
and Diamond POHs? - answer Each company will have different four Ps and each POH
will be rewritten into to the POH.
Why would emergency checklists be more similar between different airlines flying the
same model than normal procedures? - answer Due to the nature of the situation, the
systems drive the checklists in emergency situations
Before the loss of airspeed indications with Air France Flight 447, the pilot flying wanted
to climb higher to avoid weather. Why might that be a bad idea assuming they were
already at or near optimum altitude? - answer There will be less excess thrust available
if there were to be an emergency, and that was exactly what happened.
What initial action on the part of the pilot flying after losing airspeed indications would
have likely prevented the accident? - answer Should have leveled off and flew the plane
with control and do nothing. If there is an instrument error, just take time and figure out
where you are at in terms of instruments.
Why would a jet transport aircraft's stall angle of attack be different at high cruise
altitude than at 15000'? - answer The air density is lower at higher altitudes less air over
the wing, resulting in a lower stall angle of attack.
Describe coffin corner. - answer The difference between lowest and max speeds, there
will only be a 5-10 kt buffer between the two.
How can large jet aircraft cruise at high altitudes? Why do large jet aircraft cruise at
high altitudes? - answer Its more efficient to fly at high altitudes because it is colder, and
it is more efficient for the engines to fly at higher altitudes, and it does this by
compressing its own air.
Why do large jet transport aircraft typically have a moveable stabilizer along with trim
tabs on the elevator to achieve stab trim? - answer The speed range, because there is a
wide variety of speeds, and the movable stab.
, Why are accurate takeoff and landing performance important for jet transport aircraft in
terms of ground effect? - answer Because you do not have the same rotate speed each
time, because there is such a weight difference between most flights.
Why is it so critical to set the thrust accurately for a heavy-weight TRT takeoff? - answer
At heavy weight takeoff, each bit of indication makes a bigger difference in thrust.
Would a typical jet transport aircraft have positive, negative, or neutral speed stability at
Vref? Why would I care? - answer Neutral speed, because of the equal thrust point.
Why is the Control and Performance concept more suitable to precise instrument flight
in jet aircraft than the Primary and Supporting method? - answer Because of the high
speeds of a jet, every little change of pitch or attitude will make a larger difference in
VSI. You will end up chasing instruments if you use Primary supporting.
Why do jet transport aircraft not use standard rate turns during climb, cruise, and
descent? - answer Standard rate turn at high speeds is like 45 degrees, its
uncomfortable for passengers.
What is V1 and on what potential takeoff event is it based? - answer V1 is a decision
speed, that is based on engine out at that speed.
What is balanced field limit? Is every jet transport aircraft takeoff equally limited by
accelerate-go and accelerate-stop for every takeoff? - answer When you are equally
stop and go limited, when your aircraft is too heavy to take off or have an accel go.
When the two speeds are equal.
Assuming a balanced field limit takeoff and a tire failure at V1, would aborting the
takeoff make more sense or would continuing the takeoff make more sense? - answer
No, it would make more sense to take off, and then come back because how close you
are to V1. You have lost stopping capability with a lost tire.
What aircraft system is most effective in decelerating a jet transport aircraft on the
runway either after landing or during an abort? - answer Breaks are what stops the
aircraft.
If your jet transport aircraft has two takeoff flap options, in what circumstance would
you use the greater flap option? In what circumstance would you use the lesser flap
option? - answer Shorter runway is when you would use greater flaps. 10 degrees is
