FLYING THE MACJET
Study the following drawings of different trimmer setting and speed-system use and
their influence to the wing stability.
Released trims without brakes
Preferred setting for fast and safe flying. The centre of gravity of the airfoil is moved
forward, the wing has higher resistance to collapses. Pitching moment decreases.
Released trims with brakes applied
The MacJet uses a flap system in the centre of the wing on the trailing edge for
improved take-offs and landings. This provokes more lift in the centre of the wing
and also increases the pitching moments. Even slight brake input (especially on
full speed bar) produce lift close to the trailing edge. The centre of gravity of the
airfoil is moved back and the higher pitching moment significantly decreases the
stability.
Warning!! Especially in turbulence this can lead to a collapse on full speed with
trims released! Therefore we recommend pilots only use the wing tip steering
system.
