SEATS, SEAT BELTS
The seats are ergonomically shaped composite designs. The rear seat angle can be
adjusted on the ground with 2 quickpins, there are different seat angle possibilities. The
back rest is also adjustable on the ground in different positions and angle. The rear pedal-
to-seat distance can be varied in different positions. In the front cockpit there is no possibility
to adjust either the pedals nor the seat. The seat belt assembly consists of a left and a right
shoulder strap, two left and two right lap belts and a negative-g-strap. All belts are
adjustable. As each lap belt features a single point release, they are redundant for safety
during aerobatic maneuvers. If one release is opened unintentionally, the second one
guarantees full safety. For safe operation the releases are arranged in a way that one has to
be closed to the right side, the other one to the left. During acrobatic maneuvers the seat
belt system should be tightened firmly.

CANOPY
The canopy is manufactured in one section and can be manually operated by interior locking
handles located on the left side on the canopy.
To open the canopy from inside proceed as follows:
Pull together the interior locking handles of the front or rear seat and lift canopy to the right.
The canopy strap will limit the opening angle.
To lock the canopy pull together the interior locking handles and then release.
To open the canopy from the outside use the aft interior handles by reaching through the
small window (bad weather window) and proceed as mentioned above.
Generally the emergency operation is equal to the normal procedure. When opening the
canopy in normal flight the low pressure over the canopy will flip the canopy fully open
immediately. However complete jettison of the canopy is possible. In this case the canopy
can be finally unlatched at its RH hinge line by the following action:
push canopy slightly forward while opening.
