Fer109 Posted November 8, 2016 Posted November 8, 2016 On ground, when oxygen switch is off, oxygen pressure indicator marks zero, but it should indicate pressure (around 65 psi). In DCS we only have pressure indication after placing oxygen switch to on. Oxygen pressure indicator is not related to oxygen switch position. If working fine, should mark pressure always (as far you have some oxygen quantity). (Can be checked in a real F-5)
