Pilot Panel

Sequence System



Monitors the current status and progress of the boost phase, and to anticipate an abort condition if one should develop. These meters indicate the gas pressures in psis of the stage 1 fuel and oxidizer tanks. Dual indicater needles are provided for redundancy. The range of the stage 1 meters is 35 to 5 psia. A time versus-pressure scale near the bottom of the meter shows the minimum required pressure at 20, 40, and 60 seconds after lift-off. Critical fuel tank pressure is indicated by a shaded column at the low end of the scale. After staging with no signals applied, the meters indicate maximum psla.
