It is the period of time from the interruption of the oxygen supply or exposure to an oxygen-poor environment to the time when useful function is lost, and the individual is no longer capable of taking proper corrective and protective action. It is not the time to total unconsciousness. At the higher altitudes, the TUC becomes very short ...
According to an AOPA chart on "time of useful consciousness" (below), SWA1380 passengers had about 30 seconds to get their masks on after the window blew open: hypoxia time useful consciousness ...
The aircraft involved was Boeing 737-3H4 [a] with registration N632SW, manufacturer's serial number 27707, [11] line number 2799. [12] It was delivered to Southwest in 1996 and at the time of the accident had completed 48,748 hours and 39,786 cycles.
The oxygen systems have sufficient oxygen for all on board and give the pilots adequate time to descend to below 8,000 ft (2,438 m). Without emergency oxygen, hypoxia may lead to loss of consciousness and a subsequent loss of control of the aircraft. Modern airliners include a pressurized pure oxygen tank in the cockpit, giving the pilots more ...
In the aftermath of the incident aboard an Alaska Airlines 737 Max 9, we look at what happens when an aircraft experiences a sudden loss of cabin pressure and the risks for those on board.

But assuming they were at 30,000 and climbing, they would have had about one to two minutes of useful consciousness before passing out.” But he said this plane's autopilot system did what it was ...
Actually, the Time of Useful Consciousness is indefinite at roughly 15,000 ft, where the partial pressure of oxygen is only 50% of the pressure in a 100% oxygen mask at 34,000 ft. Thus, you should be able to maintain useful conciousness indefinitely when the pressure in the O2 mask is 50% of the partial pressure of O2 at sea level, which means ...
