NOTE: Always crosscheck the HYD 2 caution
light subsequent to RAT extension. There is a
possibility that RAT extension was the result of
momentary high demand on the HYD 2 EDP
and not pump failure. In this case, the HYD 2
light will extinguish at EDP pressure of 2000 psi
and HYD 2 can be reset.

(1) Indicates pressure in HYD 2 FC
accumulator (accumulator pressure,
as opposed to system output pressure read
from HYD 2 pressure gauge in cockpit)
(2) Calibrated from 0 to 4000 psi increments
and labeled every 1000 psi
(3) When hydraulic fluid supply is depleted
from accumulator, gauge displays nitrogen
