4. ALT WARN
A pneumatically operated outflow valve, located in the aft pressure bulkhead, maintains the selected cabin altitude and rate-of-climb commanded by the cabin rate-of-climb and altitude controller. As the aircraft climbs, the controller modulates the outflow valve to maintain a selected cabin rate of climb and increases the cabin differential pressure until the maximum cabin pressure differential is reached. At a cabin altitude of 12,500 feet, a pressure switch mounted on the back of the overhead control panel completes a circuit to illuminate a red ALT WARN warning annunciator, to warn of operation requiring oxygen.
Warning Annunciator
Tak tato kontrolka se mi rozsvítí od FL120 a háže celou dobu červené varování dokud neklesnu na FL100. Jediné ,co jsem našel je přepínač oxygen a mikrofon v oxygenové masce.Nic na to nereaguje a svítí to dál  Co to prosím po mně chce a nebo nemůže stroj prostě létat výš ????
Děkuji za pomoc. |
