MCQ Aircraft Landing Gear Components & Hydraulic
System.
1. An excessive cleaning on the trunnion using abrasive
method may lead to which type of defect?
a.Hydrogen embrittlement
b.Mechanical damage such as sractch and dent below 0.1mm
c.Accidentally removal of the coating lead to the formation of
pitting corrosion under stress and SWAMP area.
2. Microswitches design to enable the failure at uplock
position for what purpose?
a.To warn and inform the pilot on the proper action to be taken
in those situation instead of failure at uplock which could end up
with extension
b.To warn and inform the pilot on the proper action to be taken
in those situation instead of failure at downlock which could end
up with belly landing
c.To warn and inform the pilot on the proper action to be taken
in those situation instead of failure at transit which could end up
with belly landing
3.Due to the type of material trunnion were made of the
most suitable NDT would be?
a.Only FPT applicable
b.ET , UT and FPT
c.Thermography and acoustic
4.In an opposite actuator retraction the excessive
hydraulic fluid pressure shall be relieved by ?
a.Check valve
b.Manual bleed valve
c.Pressure relief valve
5.The actuator use for the restraction and extension of
the landing gear is of which type?
a.Double acting
b.Brake type actuator
c.Single acting
