ASA Assembly & Rigging Questions and

What is the primary function of a helicopter rotor system?
✔✔The rotor system generates lift, allowing the helicopter to take off, hover, and maneuver in
the air.
How do collective and cyclic pitch controls differ in helicopter flight?
✔✔The collective pitch control adjusts the pitch of all rotor blades simultaneously to change the
overall lift, while the cyclic pitch control changes the pitch of individual rotor blades to control
the direction of flight.
What is the role of a helicopter's tail rotor?
✔✔The tail rotor counteracts the torque produced by the main rotor, providing stability and
directional control.
How does the phenomenon of "ground effect" influence helicopter performance during takeoff?
✔✔Ground effect occurs when a helicopter is close to the ground, enhancing lift and reducing
power requirements, making takeoff easier.
1
,What is a critical factor to consider when performing a weight and balance calculation for a
helicopter?
✔✔The distribution of weight and center of gravity must be within specified limits to ensure
stable flight and control.
How does a helicopter achieve a hover?
✔✔A helicopter achieves a hover by balancing lift and weight while adjusting rotor pitch to
maintain altitude.
What are the primary components of a helicopter's flight control system?
✔✔The primary components include the cyclic control, collective control, and anti-torque
pedals, which together control the helicopter's movement.
What is the purpose of the helicopter's governor system?
✔✔The governor system automatically regulates engine RPM to maintain consistent rotor speed
during flight.
How does the design of a helicopter's rotor blades affect its performance?
2
, ✔✔The shape, length, and material of rotor blades impact lift, drag, and maneuverability,
influencing the overall performance of the helicopter.
What is the significance of autorotation in helicopter flight?
✔✔Autorotation allows a helicopter to descend safely without engine power by using the
upward flow of air to keep the rotor blades turning.
What are the common types of helicopter rotor systems?
✔✔Common types include single main rotor, tandem rotor, and co-axial rotor systems, each
offering different flight characteristics.
How can a pilot determine if a helicopter is experiencing Vortex Ring State?
✔✔Signs of Vortex Ring State include a rapid loss of altitude and an increase in power required
to maintain flight, often accompanied by an unresponsive control system.
What safety checks should be conducted before a helicopter flight?
✔✔Pre-flight checks should include inspecting fuel levels, control surfaces, rotor systems, and
emergency equipment to ensure safe operation.
