Physiologic Deficient Zone
TUC=Time of useful Consciousness - ANSWER-10K to 50K ft MSL
O2 pressurization is required
Sign of compression loss is cooler temperature and window fogging.
Normally 90 Sec TUC at 30000ft
If a rapid decompression occurs TUC is @45 Sec
Pressure Values - ANSWER-Sea level = 760 Torr = 1 ATM
10K = 523 Torr
18K = 380 Torr = 1/2 ATM
