ACES II Flashcards
What initiates the E O2 system during an ACES II ejection?
The ejection seat moving up the guide rails.
Briefly explain the operational mode 1 of the ACES II system.
Low speed, low altitude ejection where the parachute deploys immediately after the seat departs the aircraft.
Which mode does not use the drogue?
Mode 1
What are the two main differences between modes 2 and 3.
Mode 2 is low altitude so the drogue is immediately deployed while in mode 3 its delayed as well as man seat separation and deployment of the parachute.
What function does the pilot parachute serve?
Strips the container off the packed recovery parachute.
What purpose does the emergency handle serve?
Disconnects the parachute container from the seat, releases the pilot parachute to deploy it allowing the crew-member to separate from the seat.
Name the major components of the recovery parachute systems.
Pilot parachute, canopy, risers, reefing line cutter, harness/canopy release, mortar, pitot tubes, mortar sleeve, container, and drogue.
Briefly describe the ACES II pilot chute bridal line.
29 in tubular line made in the shape of a Y the point where two legs start from the Y is called the yoke.
What purpose does the reinforcement bands serve on the ACES II recovery canopy?
Prevent canopy blowout.
What is the purpose of the reefing line cutters?
Deploy the canopy in stages to reduce the opening shock at high speeds.
What lines are the back up reefing line cutter lanyards installed?
7 & 21
What is the purpose of the canopy release link assembly?
To attach the riser straps to the crew-members torso harness.
What is the purpose of the ACES II pitot tubes?
Provide data to the seat recovery sequencer.
Why are the cotton covers incorporated over the suspension line storage tunnels?
To insert the reefing line cutter pocket stays during packing.
What is the purpose of the drogue parachute assembly used on the ACES II?
To decelerate and stabilize the ejection seat and to position the seat correctly for deployment.
What are the inspection intervals for the ACES II recovery system?
Before installation, preflight, 30 day, and annually. (every 5 years for the B-1)
What is checked during a preflight on the parachute assembly?
The general condition and serviceability and checked to ensure the 30 day inspection or repack is not overdue.
What are you looking for when inspecting the reefing line cutter lanyard?
Broken rings or missing stitching.
What are you checking when inspecting the reefing line cutter lanyard?
Signs of fraying, deterioration, and attachment of the cutter firing lanyards.
Name 5 items you inspect on the mortar assembly.
Collar for damage,, missing or defective parts, contamination, O ring for defects, tightness of screws, and lock wire for correct installation.
What is the length of the installed reefing line?
156 in.
When you stow the canopy what portion of it must you center over the mortar?
Top radial seam.
What is the max amount of suspension line you can stow inside the container?
No more than 16 in.
How far may suspension lines extend beyond the top and bottom edges of the tunnels on the container?
.75 on top and 1 in on the bottom.
