What are the control requirements for a canopy jettison system in a sailplane as per CS 22.807?

The jettison system must be actuated by no more than two controls, which remain in the open position. Controls must be operable with a pilot effort between 5 and 15 daN, and designed to minimize inadvertent operation.

How should a sailplane canopy or emergency exit operate at high speeds per CS 22.807?

The opening or jettisoning of the canopy or emergency exit must not be prevented by aerodynamic forces or the canopy's weight at speeds up to VDF, or by jamming with other parts of the sailplane.

What are the design requirements for a sailplane cockpit emergency exit according to CS 22.807?

The cockpit must allow unimpeded and rapid escape in emergencies, both during flight and on the ground, with the occupant wearing a parachute.

What structural support must a sailplane provide for occupants bailing out under acceleration according to CS 22.807?

Sufficiently strong cabin parts or grab-handles must be available and located to allow occupants to lift themselves out of their seats, designed to an ultimate load of at least 200 daN.

What are the operational requirements for a sailplane's emergency exit opening system according to CS 22.807?

The opening system must be simple, easy to operate, function rapidly, and be operable by each occupant strapped in their seat and from outside the cockpit.

ED Decision 2009/009/R

(a) The cockpit must be so designed that unimpeded and rapid escape in emergency situations during flight and in any normal or crash attitude on the ground is possible with the occupant wearing a parachute. (See AMC 22.807(a))

(b) The opening, and where appropriate jettisoning, of each canopy or emergency exit must not be prevented by the presence of the appropriate aerodynamic forces and/or the weight of the canopy at speeds up to V_DF or by jamming of the canopy with other parts of the sailplane. The canopy or emergency exit attachment fittings must be designed to permit easy jettisoning, where jettisoning is a necessary feature of the design.

(c) The opening system must be designed for simple and easy operation. It must function rapidly and be designed so that it can be operated by each occupant strapped in his seat and also from outside the cockpit.

(d) A canopy or emergency exit jettison system must be actuated by not more than two controls, either or both of which must remain in the open position. The canopy jettisoning controls must be capable of being operated with a pilot effort of between 5 and 15 daN. If two controls are used they must both move in the same sense to jettison the canopy. If there are controls for each pilot, both controls or sets of controls must move in the same sense. If a single control is used for jettisoning, it must be designed to minimise the risk of inadvertent or unintentional operation towards the jettison position.

(e) In order to enable the occupants to bail out under acceleration conditions, sufficiently strong cabin parts, or grab-handles, must be available and suitably located so that the occupants can lift themselves out of their seats and support themselves. These parts must be designed to an ultimate load of at least 200 daN in the anticipated direction of force application.
