The above report raises three crucial technical questions arising from the Helios-ajet dispute with Tsolakis' findings:
1) Is it or isn't it physically (humanly) possible for a commercial airliner with 121 people on board to pressurise normally on the ground prior to takeoff - ie as engine/APU bleeds are turned on - with the Outflow Valve barely open (14 degrees from closed) instead of FULL OPEN as it should have been if the Pressurisation Mode Selector Switch was in AUTO and the ground-air sensors working normally?
2) Is it or isn't it physically (humanly) possible for a commercial airliner with 121 people on board to take off at a cabin rate of climb of 2,500ft/min, when the normal (bearable) rate of cabin altitude change is 500-700ft/min, and the minimum allowable differential with a/c flight altitude is 1,800ft/min (otherwise AUTO-FAIL)?
3) Are there or aren't there separate circuit breaker(s) for E-bay equipment cooling fans on the B737-300 models and, if so, where exactly are they located on either of the CB panels?
