Some O&G pax are wearing UEBS currently. With more moving to the technology this year.
Doesn’t seem to be any urgency in introducing it for pilots.
(Although, it is “on its way” for some companies. 3 years - normal time/ scheduled currency for HUET, to “up skil”l all crews, then some more time to roll out the hardware. This time frame might reduce if a few more pilots drown while trying to escape.)
I’ve moved from flying machines with mechanical emergency door releases, (seemed a great option) to a more modern design with a “fiddly” “filler strip” to be removed, followed by pulling the window IN with a tiny, sun faded/weakened tab. Seems unlikely to be successful in anything but ideal conditions. Worse still there is no provision to experience or practice the technique. (The push out widows in the HUET trainer are child’s play by comparison, and they never punch you in the face and break one arm before you escape from them.)
