Which combination can indicate a sustained severe compressor surge with overheating?
After air has passed through the compressor of a gas turbine engine the:
Fuel flow information for gas turbine engines is:
The manual inflation handle fitted to an evacuation-slide assembly:
On an aircraft provided with resistance and capacitance variation type fire detection loops, a fire alarm is initiated by a temperature increase detected:
Consider the flight deck oxygen supply system. The purpose of the oxygen regulator (as a function of demand and altitude) is to: 1. decrease oxygen pressure from 1800 PSI (in the bottles) down to about 50-75 PSI (low pressure system) 2. supply pure oxygen 3. supply diluted oxygen 4. supply oxygen at normal pressure 5. supply oxygen at emergency/positive pressure 6. trigger the continuous cabin altitude warning at 10000 ft cabin altitude. The combination regrouping all the correct statements is:
For the appropriate oxygen and protective-breathing equipment carried on a pressurised aeroplane, which uses are recognised? 1 - Supplemental oxygen after depressurisation. 2 - First-aid oxygen for passengers who require it under the applicable conditions. 3 - Supplying the normal cabin ventilation air directly from oxygen cylinders. 4 - Flight-crew respiratory protection with suitable oxygen masks or protective-breathing equipment during smoke or fumes. Select the combination containing all correct uses.
Which statements describe a typical passenger chemical oxygen generator? 1 - It can reduce weight and volume compared with an equivalent stored-gas installation. 2 - It has a long shelf life when stored and maintained as specified. 3 - It supplies oxygen indefinitely once started. 4 - It does not require a high-pressure oxygen storage cylinder, although the hot generator still presents hazards. 5 - It can be stopped and restarted repeatedly after ignition. 6 - It must be replaced after activation and is subject to expiry and maintenance requirements. Select the combination containing all correct statements.
The equipment of an oxygen supply installation must be kept absolutely free of oil or grease traces as:
In a pressurized transport aircraft, the protective breathing equipment:
