What is the compass direction in degrees for Southeast (SE)? - (Answer)135 degrees
Which compass directions corresponds to 270°? - (Answer)West
Describe why the heading and track can be different for a fixed wing aircraft? - (Answer)Fixed
wing aircrafts' headings will always be more into the wind than the track to counteract wind
forces.
How can multirotor RPAs (Remotely Piloted Aircraft) differ in their heading and track -
(Answer)They can be heading in one direction while tracking in another due to their ability to
move in any direction.
What is the compass direction in degrees for Northwest (NW)? - (Answer)315 degrees
In Australia, measurements less than 2 nautical miles (NM) are usually expressed in which unit?
- (Answer)Metres
What is Mean Sea Level (MSL)? - (Answer)The average sea level all over the world.
How is 'height' defined in the context of Aviation - (Answer)The difference between an aircraft
and a surface, usually the ground
Which factors contribute to an increase in potential energy? - (Answer)Height and Weight
What happens to kinetic energy when speed increases? - (Answer)It increases
, What is inertia related to? - (Answer)The power required to push or stop an object.
What is Relative Airflow? - (Answer)Relative Airflow is the speed of the air passing over an
object in the opposite direction to travel
According to Newton's third law, what happens when a multirotor generates down thrust? -
(Answer)It is pushed upwards.
What is the effect of placing a weight off-center on a multirotor? - (Answer)It will cause the
multirotor to lean in that direction and require the motors on that side to work harder.
How does a multirotor move in a desired direction? - (Answer)By increasing the lift of the
propellers at the rear and decreasing the speed at the front for the direction of travel.
What principle is used to stop a multirotor from moving forward? - (Answer)Applying the same
principle used to initiate forward movement but in reverse.
Why does a propeller have a larger twist at the root and taper narrower toward the tip? -
(Answer)To reduce the thrust at the tip where the blade is weakest.
What is the Remote Pilot Station used for? - (Answer)To control the RPA and receive telemetry
information.
What type of information is typically displayed on the screen of the Remote Pilot Station? -
(Answer)Height, speed, heading, battery level.
What does the pitch control do on a multirotor? - (Answer)Initiates, controls speed, or stops
movement forward or backward.
