Normal procedures
and recommended speeds
To enter the cabin first lift the glass door all the way to the bottom wing surface. The silver knob
will grab and secure the glass door in position. Sit onto the cabin's edge and support your body by
placing hands onto this same cabin edge. Drag yourself into the seat lifting first the inner and then
the outer leg over the control stick. Immediately after having sat into the seat, check rudder pedals'
position to suit your size and needs. Bring the pedals closer or further away by removing the pin in
between the pedals and slide them to desired position. Do not forget to re-insert the pin in order to
secure pedals in position.
To lower the door DO NOT attempt to grab and pull door's handle but gently pull the silver knob
instead. To close the door securely, rotate the handle so that it locks (click here to see picture) and
verify that all three closing points are secured.
Fasten the safety harnesses according to your size.
WARNING!
The safety harness must hold you in your seat securely. This is especially impor-
tant when flying in rough air, as otherwise you may bump into the tubes and/or spars overhead.
