The intensity of the LCD backlighting is obtained from the aircraft dimming bus and a measurement of the ambient light in the cockpit. The ambient light is sensed by a photodiode on the front bezel.

The ozone converter prevents damage to the air separation module from oxidation of the membrane material by ozone.

The airplane fuel system supplies pressurized fuel from the center or main tank.

Before inspection, you should remove access doors and fairings.

The circulation of the air in the components is such that the temperature for specific component is not out of the limit.

Turbine blade tip clearances decrease when the turbine case is cooled.

This can cause a deterioration of the mechanical properties of the assembly.

The assembly extends through the casing assemblies and is connected to the telescopic control assembly.

Loosen the air valve nut one or two turns to slowly release the air pressure. Drain hydraulic fluid by inverting shock strut or removing check valve.

Outside Air Temperature is the free air static temperature, obtained either from inflight temperature indications or ground meteorological sources, adjusted for instrument error and compressibility effects.

In some cases, extension of inspection frequencies may be possible if the data suggests that the onset of fatigue problems occurs at a greater number of flight hours than initially predicted.
