25. Pilot's seat control - the seat is adjustable for height by means of a lever on the right hand side of the seat.
26. Safety harness release - in order that the pilot may lean forward without unfastening his harness, a release catch (73) is fitted to the right of the seat.
27. Cockpit door - To facilitate entry to the cockpit a portion of the coaming on the port side is hinged. The door catches are released by means of a handle at the forward end. Two position catches are incorporated to allow the door to be partly opened before taking off or landing in order to prevent the hood from sliding shut in the event of a mishap.
