ATPL Principles of Flight - Control Exam
Questions and Answers with Verified
Solutions | Latest Updated 2026
rotation around the lateral axis Pitching
(and is related to longitudinal
stability)
rotation around the Rolling
longitudinal axis
rotation around the normal Yawing
(vertical axis)
back pressure on control To pitch up
column = elevator moves up
+ negative camber of
tailplane/elevator increases (to
provide downforce)
requires stabiliser to produce Trimmable horizontal stabiliser
more downforce therefore (forward CG)
lower stabiliser AoA needed
less nose down pitching Trimmable horizontal stabiliser (aft
moment from the CG)
wing-stabiliser does not need
to produce as much down
force-so stabiliser leading
edge higher
