Ice and Rain Protection Flashcards
When the ice detector (located at the bottom of the fuselage) accumulates ice to a predetermined thickness what happens ?
An alert will be presented.
The ice detector will then be regularly de-iced to check if icing conditions still exist.
The alert will remain until it no longer detects ice as having been accu
A black stripe is provided on the outboard wing to ?
Help to determine if there is ice contamination on the wing during flight and on the ground
Engine Anit-Icing is provided to ?
- The nacelle leading edge
- The inside of the air intake
- The engine spinner
The air that is discarded from the nacelle anti-icing flows back into the engine to provide ?
Anti-icing for the air intake
Ice protection for the conical spinner is provided by a ?
Flexible rubber tip
When wing anti-icing is selected via the wing anti-icing p/b, a pressure modulating and shutoff valve is opened, provided what 2 conditions are met ?
- The aircraft is airborne
- Bleed-air pressure is sufficient
In case of a wing bay overheat or a duct overpressure, the modulating and shutoff valve will ?
Close and an alert will be presented
Operation of the wing anti-icing system is inhibited as long as ?
- Either thrust lever is set to the maximum TLA, AND
- For approx 60 seconds after lift-off, OR TOGA activation
On the ground, the on ground wing leading edge heating system, provides a
means of wing anti-icing when used in addition to approved de-icing and antiicing procedures and is automatically activated when ?
Either engine anti-icing system is switched on, provided the aircraft is on
the ground AND bleed-air pressure is suffIcient.
A relevant system alert will be presented in case of 3 conditions ?
- A wing leading edge overheat
- A wing leading edge low temperature, OR
- A control system failure.
Operation of the on ground wing leading edge heating system is inhibited as long as one of these two conditions are met ?
- Either thrust lever is set above the MIN TO position AND,
- The aircraft is airborne, OR
- For approx 60 seconds after the TOGA triggers are activated.
A wing leading edge low temperature can
be caused by 2 conditions ?
- A system failure, OR
- A too low bleed-air supply pressure
When engine anti-icing is on during landing, the on ground wing leading edge
heating system will ?
Automatically be activated after touchdown.
When tail anti-icing is selected via the tail anti-icing p/b, a temperature modulating
and shutoff valve is opened, provided ?
The aircraft is airborne and bleed-air pressure is sufficient.
Low temperature will be detected and the relevant low capacity alert presented.
In case of a duct or bay overheat ?
The modulating and shutoff valve will close and an alert will be presented.
Operation of the tail anti-icing system is inhibIted as long as ?
- Either thrust lever is set to the maximum TLA, AND
- For approx 60 seconds after lift-off, OR TOGA activation
In relation to the Pitot and Static system an alert is presented when ?
- A pitot heat system fails or;
- A vane heat system fails or;
- A pitot heat system is OFF with the aircraft on the ground and the PARK BRAKE released.
In a battery-power-only condition, which pitot heat sensors are heated ?
Only pitot head 1
The flight deck front windows and sliding windows are ……. heated ?
Electrically
Two independent systems automatically control the window heat to the required temperature for anti-icing, demisting and increased impact resistance.
Each system has …. operating channels ?
2
One channel provides temperature control and monitoring for a front wind
In the event of a front window malfunction the respective channel is …(1)… ?
Failure of the sliding window heating is indicated by an alert …(2)… ?
- Auomatically de-activated and an alert is presented.
- On the maintenance test panel only.
In the park position the blade is ?
Lifted just clear from the window surface.
