“Investigators of the Payne Stewart incident never concluded the speed of the decompression - whether it was slow or rapid. A commercial airliner’s oxygen systems are automatic and should deploy when the cabin pressure exceeds a certain altitude - something not required of private jets. They also deploy for the pilots. At 35,000’ the time of useful consciousness is from 30 to 60 seconds”
You are not familiar with FAA certification standards. I am type rated in several types of “private” jets and they all have automatic oxygen mask deployment. On the other hand, pilot’s oxygen masks do NOT deploy automatically. Pilot’s have quick donning oxygen masks.
Thank you for the correction.
