An
aircraft that isn’t of aerobatic standard can still perform aerobatics because
every plane has to be able to withstand with stand +3.8 Gs to - 1.52 Gs at
least. This can often be observed at air shows, the difference between this and
aerobatics performed in an aerobatic category plane is that there is no room for
error. A problem with doing aerobatics in a non aerobatic plane is it is very
dangerous and only the most skilled aerobatic pilots should attempt it is that
if its not in the aircraft’s manual you now have an experimental aircraft and
it has to be re-certified.
The
manoeuvring speed (Va or Vman) is very important to aerobatics because it is the
speed at which the pilot can apply full deflection of pitch, roll and yaw
controls without exceeding any of the relevant limitations. At the maximum Va
the application of full pitch, roll or yaw control will overstress the aircraft,
and the aircraft will fall out of the sky.
