[WORKS AS INTENDED]Above Angels 25 Oxygen should be at 100%

[DmitriKozlowsky]

Right now leaving LOX dilution at N (normal) has no physiological effect. I think that p[rogression is loss of color vision, blurriness, loss of consciousness .

Actually no. The normal flight position is "NORMAL" and you will be fine up the aircraft operational ceiling around FL500.

Normal oxygen switch is for the on board O2 tank.

Emergency oxygen is for the seat emergency tank.

Cockpit pressure is the parameter that counts.

PCAB alarm will light up if pressurisation issue is detected, thus exposing the pilot to hypoxia

Oxygenation of cabin atmosphere is not a concern for pilot health, right? He is wearing a mask.

what about cabin pressure ?

[El Chapo]

O2 % in the oxygen mask is automatically regulated.

Without mask or cabin pressure you should not fly above FL115.

With an O2 mask and without cabin pressure you can fly up to FL235.

With a mask and cabin pressure you can fly up to FL500.

Above that you normally need pressurised flight suit.

System is working as intended.
