Getting any lower, or fluctuating? Why I ask: years ago I had a similar issue where a check valve on Emer Air side had corroded, letting emergency "down" air bleed into the system to oppose the "up" from the normal side. LG wouldn't budge going up. Replaced the faulty check valve and all was fine afterwards. Regardless, I'm sure it's a straightforward snag to fix, just got to find the gremlin...

Both cockpit gauges show Emergency Air at 55 atmospheres, and they never go down, even after weeks of sitting Thanks for all of the help! It is much appreciated!
