The ACES ejection seats currently utilize a Recovery Sequencer based on analog technology to control ejection event timing and ejection mode selection. The Recovery Sequencer has limitations with respect to installed life, electronic component obsolescence, flexibility to accommodate seat safety improvements, and mode differentiation at the Mode 1 to 2 crossover point. The Digital Recovery Sequencer DRS program was undertaken by Goodrich, the seat OEM, and the CADPAD Joint Program Office JPO to design and qualify a sequencer based on digital technology that overcomes the limitations of the Recovery Sequencer. The DRS Program was broken down into three phases.
