State the purpose of the hydraulic patch test
|
To ensure the cleanliness and purity in the hydraulic system
|
|
State the purpose of the Blade Inspection Method (BIM) indicator.
|
In the leading edge of the blade there is a spar that runs the length of the blade. The spar contains nitrogen and if there is a leak in the spar the BIM will change to 3 black lines
Under proper conditions the BIM is all white |
|
State the purpose of conducting Flight Control system rigging

To bring the flight control perimeters into straight level flight, as set by factory
|
|
State the purpose of a tactial paint scheme
|
The paint design is for each A/C type to reduce visual detection by matching reflection of operational surroundings.
|
|
State the 2 methods of locking and unlocking tail wheel lock pin
|
manually

|
State the factors that affect rotor blade lift
|
Increasing the pitch of the main rotor blades creating a high-pressure area on the lower side of the blade and a low pressure area on the upper side of the blade, this creats lift. Lift must be greater or equal to weight if list is to be sustained.
|
|
State the location and purpose of the main rotor head dampers
|
Between each spindle
Purpose is to reduce the lead and lag of teh main rotor blades and absorb main rotor head start load. |
|
Explain how the the collective stick affects helicopter flight
|
changes the pitch of the main rotor blade. increace or decrease lift
|
|
Explain how the cyclic stick affects helicopter flight
|
changes the angle of the rotor disk. controls forward aft and lateral movement
|
|
Explain how the rudder pedals affect helicopter flight
|
changes the pitch of the tail rotor blades. controls helicopter heading
|
|
State what must be done for effective helicopter corrosion prevention
|
A/C must be washed every 7 days at sea and every 14 days ashore
|
|
State the 2 areas on the helicopter, which must have particular attention during a corrosion inspection
|
gear boxes
avionics |
