The geometry of the ONYXJET MK3 ejection seat is inspired by the ACES II seat of the F-16. Like its prototype, the seat is inclined by 30 degrees. It also includes a harness system, produced by Mil-Tec, an Adjustable headrest and a Sony SRS-X88 sound system. Inside the seat, there is an extra compartment with a USB hub, space for cables and a power strip.
