Helicopter License — Study Guide
Helicopter systems, performance, controls, and operating limitations.
Baggage and cargo must be properly stowed and fastened, otherwise a shift of the cargo may cause...
Unsecured cargo can cause uncontrollable attitudes, structural damage, and injuries.
The power output of most turbine engines is limited by...
Compressor RPM, turbine outlet temperature, and the main rotor gearbox limit turbine power.
What are the variable physical properties of the atmosphere that affect helicopter performance?
Temperature, pressure, and humidity directly impact lift and engine performance.
The maximum power output of helicopter piston engines is usually limited by...
The main rotor gearbox sets the power limit for piston engines.
Which factor has a positive effect on the power required for flight?
Clean blades reduce drag and improve efficiency.
The total weight of a helicopter is acting vertically through the...
The centre of gravity is the point where weight acts.
What needs to be observed if the carburettor heat is applied in a hover?
Applying carburettor heat causes a loss of power while hovering.
Why does the Vne (never exceed speed) decrease with increasing pressure altitude?
True airspeed increases with altitude, reducing safe margin at Vne.
What is the main function of the main rotor in a helicopter?
The main rotor provides lift, thrust, and stability to maintain control.
What is rotor speed?
Rotor speed is the rate at which the rotor blades rotate.
What are the primary controls for maneuvering a helicopter in flight?
Helicopters use cyclic, collective, and pedals to control movements (equivalent to ailerons/elevators in planes).
What is helicopter pitch?
Pitch is movement around the longitudinal axis (nose up/down).
What is the primary source of propulsion in a helicopter?
Most helicopters use piston engines, though some use turbines.
What factors affect the lift generated by a helicopter's rotor?
Flight speed and blade angle of attack determine lift.
What does the element labeled in the helicopter cockpit photo represent?
The joystick (cyclic control) manages helicopter tilt and direction.
What is this helicopter component responsible for?
It provides stabilization and controls the helicopter's directional flight.
