How long is the time delay for the reefing line cutters to fire on the ACES II parachute?

The time delay for the reefing line cutters to fire on the ACES II parachute system is specifically set to 1.15 seconds. This delay is crucial for ensuring that the parachute can deploy properly and stabilize before the reefing line cutters are activated. The design of this delay balances the need to allow the parachute sufficient time to open fully while also ensuring timely activation of the cutters to facilitate a safe descent when necessary.

Understanding this delay is essential for aircrew members, as it impacts parachute performance and safety in various flight scenarios. Proper knowledge helps them manage expectations during a potential parachute deployment and contributes to overall mission effectiveness and safety.
