TECNI DATA

The purpose of the wing anti-icing is?. Prevents anti-ice build up on the Leading edge Slats only if are retracted. Prevents anti-ice build up on the leoding edge slats extended or retracted. Prevents anti-ice build up on the Leading edge Slats only if are extended.

With the Wing Anti-ice switch selected to ON and light is illuminated BRIGHT BLUE it means?. Anti-Ice Valve is OFF. Anti-Ice Vave in transit or Disagreement. Anti-Ice Valve is OPEN.

Does the wing TAI also protect the leading edae Flaps?. NO, only the 3 outboard slats (there are 3 slats on each side; total of 6). Yes all leading edge flaps. NO, only the flaps.

The wing anti-ice valves will close when. The temperature in the engine reaches a preset limit on the ground or in flight. there is an overpressure in the Anti-Ice duting sensed by the ground thermal switch. The temperature in the Anti-ice ducting reaches a preset limit, thru the ground thermal switch.

What are the three conditions for opening the Wing Anti-ice Shutoff valve?. Wing Anti-Ice Valve switch in OFF, No OVHT conditions exist, No Engine thrust levers in advance. Wing Anti-Ice Valve switch in ON, No OVHT conditions exist, No Engine thrust levers in advance. Wing Anti-Ice Valve switch in ON, No OVHT conditions exist, Engine thrust levers in advance.

What means when the probe heater lights comes on?. The associated probe is heat is inoperative and when the pitot static heat switch OFF. The associated probe is heat is operative and when the pitot static heat switch ON. The associated probe is heat is inoperative and when the pitot static heat switch ON.

Where does the wing anti-ice Shutoff valves are located, & operated from?. Outboard of each engine struts in the wing LE. : operated from P5. Inboard of each engine struts in the wing LE. : operated from P3. Outboard of each engine struts in the wing TE. : operated from P5.

How is powered the drain mast when the aircraft is in flight?. The drain mast receive the power from AC BUS No.1 115Vac. The drain mast receive the power from DC BUS No.1 115Vdc. The drain mast receive the power from AC BUS No. 1 28Vac.

What is the purpose of the wing thermal anti-ice system?. Prevents ice- Buildup on Leading Edge slats by blowing hot air from the Pneumatic manifold. Permits ice- Buildup on Leading Edge slats by blowing hot air from the Pneumatic manifold. Prevents rain-buildup on Leading Edge slats by blowing hot air from the Pneumatic manifold.

How is the engine TAI valve operated?. It is electrically controlled, pneumatically operated. It is pneumatically controlled, electrically operated. is mechanically controlled, pneumatically operated.

After the overheat lights have illuminated during OVHT test. The window heat switches must be momentarily positioned to RESET to reset the system. No action is required as the resetting of the system is automatic. The window heat switches must be momentarily positioned to OFF to reset the system.

During a flight in icing conditions with wing anti-icing selected to ON. The system will automatically select the wing anti-ice valves to "closed" if the temperature in the leading edge is too high. The associated wing anti-ice valve will automatically close if the pressure in the wing leading edge is too high. There is no direct control over the amount of heat supplied other than variation of engine power.

Thermal air for wing anti-icing is obtained from. Bleed air ducted from the main pneumatic manifold. 9th stage engine bleed air only. .5th stage engine bleed air only.

If the engine anti-ice switch is selected ON, and a cowł valve failed in the closed position then the COWL VALVE OPEN light. Will illuminate dim blue after 5 -7 seconds. Will be extinguished. Will be illuminated bright blue.

The total air temperature probe. Is not heated while on the ground. Does not require heating. Is electrically heated.

Rain repellant is actuated. Automatically and momentarily when the windscreen wipers are selected ON. By pressing the single rain repellent button located on the overhead panel. By pressing one of two rain repellent buttons located on the overhead panel.

Heat is applied to the alpha vanes. Automatically when either generator bus is powered. By selecting the Stall Vane heater switch on the stall warning test panel. By switching on the pitot static heaters.

The wing anti-ice valves will. Close when the pressure in the anti-ice ducting reaches a preset limit on the ground only. Close when the temperature in the anti-ice ducting reachesa preset limit on the ground or in flight. Close when the temperature in the anti-ice ducting reaches a preset limit on the ground only.
