ACES II

ACES II is an ejection seat system manufactured by the Collins Aerospace division of Raytheon Technologies (RTX).

In addition, the buying power of 5,000 in-service seats and previous service life extension programs have further driven down support costs.

For example, it senses the conditions of the ejection (airspeed and altitude) and selects the appropriate drogue and main parachute deployments to minimize the forces on the occupant.

[3] The minimal ejection altitude for ACES II seat in inverted flight is about 140 feet (43 m) above ground level at 150 KIAS.

Excellent terrain clearance performance under 250 KEAS is achieved by deploying the main parachute immediately after exiting the cockpit.

The Weber Aircraft ACES production line eventually closed as USAF needs for ejection seats declined.

USAF Capt Christopher Stricklin ejects from his F-16 with an ACES II ejection seat on 14 September 2003 during a Thunderbirds demonstration in Idaho . Stricklin was not injured.
