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.
