The aeroplane shall be controllable and manoeuvrable under
all anticipated operating conditions, and it shall be possible to
make smooth transitions from one flight condition to another
(e.g. turns, sideslips, changes of engine power, changes of
aeroplane configurations) without requiring exceptional skill,
alertness, or strength on the part of the pilot even in the event
of failure of any power-unit. A technique for safely controlling
the aeroplane shall be established for all stages of flight and
aeroplane configurations for which performance is scheduled.
Note.— This Standard is intended, among other things, to
relate to operation in conditions of no appreciable atmospheric
turbulence and also to ensure that there is no undue
deterioration of the flying qualities in turbulent air.
