|
- Life Preserver
- low profile floatation collar
- equipped with Flu-8B/P |
|
When is the LPU-36/P authorized for use?
|
- only with aircraft equipped with the ejection seat system
|
|
What does the Anti-Gravity suit consist of?
|
- bladder system encased in fire-resistant cloth |
|
How does the Anti-Gravity suit operate?
|
- bladders automatically inflate as G-forces increase
- applies pressure on the body to restrict downward flow of blood to aircrew feet and waist
- lessens the effects of black out |
|
What is the PHSRU?
|
- Parachute Harness Sensing Release Unit
- Sea Water activated release system - provides a back up automatic mode of separating the parachute from the aircrew |
|
What is the HDU?
|
- Helmet Mounted Display Unit
- uses miniature display components - allows symbology to be projected onto the visor and superimposed in the operator's view
- provides a way of recording real-world view - routes the video to the cockpit video recording system (CVRS) |
|
What is the purpose of the ejection seat?
|
- provides aircrew a place to sit during normal conditions
- propels occupant out during emergency situations |
|
What is the SJU-17A (V) 2/A?
|
- variant of the Navy common ejection seat (NACES)
- automatic - rocket assisted |
|
How is ejection initiated?
|
- by pulling the ejection control handle located on the front of the seat bucket
|
|
How is the Ejection Seat System operated?
|
- ballistic gas pressure - produced by ejection seat initiators - fired by ejection control handle - each initiator has 2 cartridges (L/R) |
|
What does the Ejection Seat System right cartridge do?
|
- gases start the canopy jettison sequence - activates the seat electronic sequencer - activates seat restraints - fires the seat catapult after a delay inserted by the escape system |
|
What does the Ejection Seat System left cartridge do?
|
- gases redundantly activate the seat electronic sequencer - provides a backup source to fir the seat catapult if the right cartridge fails |
