Interesting and Unexpected Pressurization Incident

Featured Replies

Here's what happened: About 2.5 hrs after engine start, FL310, heard a very short beep, about 3-4 seconds apart, 3 times. Pressurization panel showed cabin alt at 15,000, Diff Press about 5.5. Went to manual, AC, closed the valve to about the 1/4 position and cabin began descending at about 1500fpm. At cabin alt of 10,000 reduced rate to 400fpm by opening the valve a few notches (clicks). At cabin alt 6,500 reset the Auto function okay. Tried to reset the auto function 2 times initially, but to no avail. It was completely unexpected, all the controlls worked as they should to correct the problem. Was this possiblity programed into the Tnmouse II, or was it a "glitch"?

It's a glitch in the auto mode, but luckily the stby mode is there to recover as with the real McCoy. One of my friends who flew the -200 said he wished he had a dollar for every time he had an issue with the auto controller.At any rate, even more work has gone into the pressurization controller in v1.2, so hopefully most of the dragons are slain.CheersBob ScottATP IMEL Gulfstream II-III-IV-V L-300Santiago de Chile

At any rate, the info from the B737.uk site was a lot of help, and the problem was a tribute to the Tinmouse program.
