Hi,

I would like first to thank you for the great job of the b767-300, it is a wonderful aircraft, however there is a strange problem that i face:

In the overhead panel, the cabin altitude gauge, this gauge (the middle gauge in the pressurization panel) if the panel knob is set to Auto 1 or Auto 2 modes, it should not exceed 6000 feet even if the aircraft is on fl370, but i noticed that the gauge always indicates half the cabin altitude, that means that if the aircraft is fl200, the gauge reads 10000, and if the aircraft is fl300, the gauge reads 15000.

I think that was a fault as the cabin pressure altitude should not exceed 10000 or a warning and emergency would take place. When i reached fl380, the cabin altitude gauge read 19000 feet!! of course that's very unrealistic. If the cabin pressure reached that extent passengers would have died.

Please help me to fix that serious fault.

best regards

Jim
