1) How is a serrated rod ice detector bench tested? Report

Screwdriver torque test

By a motor load test

Motor test and go/no-go gap measurement

2) Windshield heating provides Report

thermal expansion for a tighter fit

impact resistance enhancement

increases strength to resist cabin pressure

3) At what pressure and temperature is anti ice fluid applied? Report

7⁰F at 100 PSI

70⁰C at 100 PSI

70⁰F at 10 PSI

4) The advantage of leading edge fluid de-icing is Report

less of a fire hazard

more efficient

aerodynamic shape is not disturbed

5) On large transport aircraft, the windshield wiper system is Report

one system for both sides but with the same power source

independent on each side but with the same power source

independent on each side with different power sources

6) Prior to securing a leading edge de-icing boot you must Report

remove all paint

paint the surface

shave rivet to prevent further abrasion

7) On a 'hot rod' type of ice detector, it is switched on Report

all the time

when selected by the crew

when in the air

8) Ice formation on wings is due to Report

suspended ice crystals melting on contact with the wing and instantly re-freezing

ice crystals forming layers on contact with the wing

supercooled water changing state on contact with the wing

9) When a vibrating rod ice detector has de-iced, the warning lamp on the flight deck Report

goes out immediately

goes out after one more cycle

goes out after a set period of time

10) De-misting of passenger windows is provided by Report

sealed window

an electrical heating element

air from the cabin

11) A deicer boot is completely bonded to the leading edge to Report

provide smoother airflow over leading edge

prevent electrical static build up

provide more efficient deicer cycles

12) In a cockpit window heater system, the autotransformer Report

supplies DC power for heating

supplies AC Power for heating

steps up output for severe weather conditions

13) Windshield rain repellent is applied Report

when rain is on windows and spread by wipers

before rain and spread on window surface by wipers

when in heavy rain so vision is unobscured

14) Pneumatic rain removal systems Report

use engine bleed air at high velocity to remove water droplets from windscreen

are not permitted on large transport aircraft

use a pneumatic motor to drive windscreen wipers

15) Windscreen wiper torque tests are carried out at Report

blade attachment end

centre point of the blade

the shaft end

16) Windscreen autotransformers Report

step down voltage

step up voltage

are used to supply extra current under difficult conditions

17) An ice deposit formed when liquid water flows over the airframe before freezing, and which is dense, tough and sticks closely to the surface is called Report

glaze Ice

rime Ice

hoar Frost

18) When testing pitot head heaters Report

they can only be checked by noting the temperature rise of the probe

they must only be switched on for the minimum time required to check serviceability

they should be switched on for five minutes to allow to stabilise before taking ammeter readings

19) Windscreen heating is supplied from Report

frequency wild generator, direct to the windscreen

DC generator, via a transformer

frequency wild generator, via a rectifier

20) A wing thermal anti-ice annunciator is illuminated permanently in flight deck without selection being made. The most probable cause would be Report

a short circuit

an open circuit

normal
