The emergency escape disconnect is located under the canopy deck. The transfer valve acts as a check valve to prevent the backflow of SMDC detonation to the seat components. The one-way transfer valve is located on the ballistic panel in the upper equipment bay. The initiator receives inputs from either the internal canopy jettison lever or external canopy jettison handles to initiate the jettison sequence. The canopy jettison shielded mild detonating cord (SMDC) initiator is located below the canopy jettison lever. The jettison is usually used with many types such as F-16 or F-18, where the transparency is so tough that the detonating cord might not be able to cut through it. At first, the ejection path has to be cleared, either in the form of a canopy jettison or its transparency scattering. 2-11.) The lever gives the pilot the capability of starting the emergency canopy jettison sequence from inside the cockpit. For a pilot to be ejected, several steps have to occur. The internal canopy jettison lever is located to the left of the main instrument panel. This single, common cable runs through the bulkhead into the cockpit, where it connects to the internal canopy jettison lever linkage.įigure 2-10.-External canopy jettison handle. My mission profile is 1000ft down the beach enjoying the view, aerobatics and occasional flights with the wife down in the Bahamas’ island chain. The cables are routed through the gun bay and are joined to a common cable at the cockpit forward pressure bulkhead. Jettison able Canopy: No one ever wants to ditch a canopy but it might be useful to do so in certain situations. 2-1 and 2-10.) Each handle is attached to approximately 8 feet of cable. The external canopy jettison handles and cables are stowed behind doors on each side of the aircraft near the radome. This is accomplished by pulling the ejection control handle on the ejection seat.īefore discussing the internal and external methods of jettisoning the canopy, a description of the system's components is needed.Įxternal Canopy Jettison Handles And Cables Our systems successfully unlock canopies, sever hatches and propel structure away so a clear path for an ejection seat or person is safe to egress the cockpit. It can also be jettisoned by initiating ejection. Canopy / Hatch Jettison is another method of providing the aircrew a clear and safe passage from the cockpit in the event of an emergency on the ground or in the air. The canopy can be jettisoned internally or externally without initiating seat ejection. The emergency canopy jettison system provides the capability to ballistically jettison the canopy in case of an emergency. ![]() Learning Objective: Recognize the system components and procedures for emergency canopy jettison. The canopy may be jettisoned by internal controls for in-flight or ground escape or external controls for ground rescue, refer to this section. ![]()
