Controls and Displays
Air.30.11
11. Valve Symbol - white/green/amber
Valves always reflect the state commanded by the ESC. They are white when
closed, green when open, and amber with DISAG displayed above the valve
when not in the commanded position.
12. Engine Bleed Readout - white/amber/red/green
Engine bleed pressure (psi) is shown above the outline of the engine. Digits
are normally white but turn amber and are boxed if limits are exceeded.
Engine bleed temperature (degrees C) is shown adjacent to the associated
engine. Digits are normally white, but turn red and are boxed if high
temperature limits are exceeded, or turn amber and are boxed when low
temperature limit (ice protection) is exceeded. The pressure regulator valves
are shown in the engine outline. The valve is green if the engine is running,
the manifold is pressurized, and the valve is commanded open; otherwise, it
is white. If no valid engine bleed pressure or temperature data is available,
digits are replaced with an amber X.
13. Air Conditioning Pack Readout (3) - green/white/amber/red
The packs always reflect the commanded state. Operating packs are green
circles with green vanes. Non-operating packs (no faults) are white circles. If
a pack overheats or is turned off due to a pack manifold failure, it is amber.
When a manifold fail occurs, it is red. Pack outlet temperatures are
programmed in degrees C. Digits are normally white but turn amber and are
boxed in amber when the pack overheats. If no valid pack temperature is
available, the digits are removed and replaced with a red X.
14. PAX Load Readout - amber
The number of passengers, as entered on the AIR control panel PAX LOAD
selector, is shown in the upper left hand corner of the screen. The number is
always the next highest multiple of ten (last number is always zero). When
the number of passengers is not available, the digits are replaced with amber
dashes.
