3.3. Seating Position in the Aircraft. Seating position is important and should be the same on every flight to ensure that visual references remain reasonably the same for every flight. When sitting comfortably, the upper part of the EADI display (border) should be visible just below the glareshield. As a general rule, a clenched fist between the top of the helmet and the canopy ensures adequate clearance for the canopy breaker during ejection. Adjust the rudder pedals to allow full travel of the rudder and associated wheel brake with the heel raised slightly off the floor. During strap-in, ensure there is enough length with minimal slack in the leg restraint lines for full rudder deflection.
