H4-3 Heli Flight Controls (3.0-3-4) Flashcards
3-0 Collective Pitch 3-0 Throttle Control 3-0 Governor/Correlator 3-3 Cyclic Pitch Control 3-4 Antitorque Pedals 3-4 Heading Control
3-2 Collective pitch control is also called
Thrust lever
3-2 What is the Governor
A sensing device that senses rotor and engine rpm and makes the necessary adjustments in order to keep rotor rpm constants.
3-2 What is a Governor in a turbine engine a function of
the fuel control system.
3-2 What is a CORRELATOR? What does it do? is it absolute?
a mechanical connection between the collective lever and the engine throttle. —Maintains rpm,–but still requires adjustments for the throttle for fine tuning.
3-3 In a piston helicopter, what is the main control for manifold pressure
Collective pitch
3-3 In a piston helicopter, what is the main control for rpm
throttle
3-3 In a piston helicopter, what instrument does throttle control
rpm
3-3 In a piston helicopter, what instrument does collective control
manifold pressure
3-3 In a tachometer (rpm indicator). What should you do if it reads Low rpm and low Mani Pressure
increasing the throttle increased mani press and rpm
3-3 In a tachometer (rpm indicator). What should you do if it reads low rpm and High mani press
Lowering the collective pitch decreases mani press and increases rpm
3-3 In a tachometer (rpm indicator). What should you do if it reads High rpm and low mani press
raising the collective pitch increases mani press and decreases rpm
3-3 In a tachometer (rpm indicator). What should you do if it reads High rpm and High mani press
reducing the throttle decreases mani press and rpm
3-3 Cyclic’s real name is
Cyclic pitch control
P factor or torque effect
Left turning tendency. The Right Decending blade has greater force than the left ascending blade thus pulling to left. (Especiall at high angle of attack)
PAEW
Personal and Equipment Working
PAPI
Percision Approach Path Indicator (0000 is too low, 0008 is kinda low, 0088 is good, 0888 kinda high, 8888 to high) (used for commercial, private will show low if looking at rnwy #)
PAR
Private Pilot Airman
PARE
Power idle, Aileron neutral, Rudder opposite, Elevator down then up gradually
PATWAS
Pilot’s Automatic Telephone Weather Answering Service
PCL
Pilot controlled lighting
PCN
Pavement Classification number
PFD
Primary Flight Display
PIC
Pilot in command (need to have license, FAA medical, and pilot cert) no logbook needed unless you need endorsement.

Ice Pelets
POH
Pilot operating handbook (so you can leave your Operators manual in the plane)
PPR
Prior Permission Required
