The bubble canopy of a Lockheed Martin F-22 Raptor Canopy of an F-22 Raptor. An aircraft canopy is the transparent enclosure over the cockpit of some types of aircraft.An aircraft canopy provides a controlled and sometimes pressurized environment for the aircraft's occupants, and allows for a greater field of view over a traditional flight deck.
A warning applied on the cockpit side of some aircraft using an ejection seat system intended especially for the maintenance and emergency crews. The "standard" ejection system operates in two stages. First, the entire canopy or hatch above the aviator is opened, shattered, or jettisoned, and the seat and occupant are launched through the opening.
On many high-performance military aircraft, the canopy is an integral part of the ejection seat system. The pilot cannot be ejected from the aircraft until the canopy is no longer in the path of the ejection seat. In most ejection seat equipped aircraft, the canopy is blown upwards and rearwards by explosive charges.
Back injury rates occur in only 1% of ACES ejections compared to 20% to 40% in most other ejection seats. [2] The A-10, F-15, F-117, B-1, and B-2 use connected firing handles that activate both the canopy jettison systems, and the seat ejection. Both handles accomplish the same task, so pulling either one suffices.
Canopy breaking horns were added to allow ejection through an unjettisoned canopy. [2] Two aircraft types operated by the Royal Norwegian Air Force, the RF-84F Thunderflash and the F-86D Sabre, were retro-fitted with Mk.5 seats at the Martin-Baker company's home airfield at Chalgrove. [2]
The Mk.4 seat was designed as an improved, lightweight version of earlier Martin-Baker seats for installation in a range of lighter, smaller aircraft types. [2] Improvements included a single combined seat and parachute quick release fastener (QRF) and a snubber mechanism to allow crews to lean forward without loosening the harness. [ 2 ]

The Mk.6 seat was developed from the earlier Mk.4 design by the addition of a rocket pack to enable zero-zero capability. [1] A variant of the Mk.6 was fitted with a compressed air cylinder crew breathing system to provide underwater ejection capability for the carrier-borne Blackburn Buccaneer aircraft.
