1What does RPIC stand for?
Remote Pilot in Command
2What are the four forces of flight?
Lift
Weight
Thrust
Drag
3What is a loaded drone?
One that has additonal weight mounted to it
4How do we properly load a drone?
By having proper balence by weight dristribution, ex. Dont let the drone tip when taking off
5What are the three axes rotation?
Roll
PItch
Yaw
6What part of an airplane causes a "roll"?
Ailerons
7What part of the airplane controls the "pitch"
Elevator
8What part of the airplane controls the "Yaw"
Rudder
9What does "roll" mean on an aircraft?
Think of a barrel roll, left wing up right wing down or vice versa
10What is the "pitch" on an airplane?
The angle of the plane up or down, ex. nose of the plane facing up or down
11What is "yaw" on an airplane?
Yaw is the lateral angle, ex. imagine a board game spinning arrow, laying flat but going left to right
12What is roll on a quad drone?
Similar to an aiprlane, essentialyl leaning left and right relative to the camera FOV
13What is pitch on a quad drone?
Imagine from the camera fov, moving forward or back by leaning forward or tilting back
14What is yaw on a quad drone?
Imagine the drone spinning like a table top
15What is lift?
The force that direclty opposes the weight of an aircraft and holds it in the air
16What is weight?
The force pulling the aircraft towards the ground
17What is thrust?
The propulion that pulls the aircraft through the air
18What is drag?
The resistance holding the aircraft back when moving through the air
19What produces lift on a rotorcraft?
Motors
20What produced lift on a fixed wing aircraft?
Wing (airfoil)
21What does C.P. or C.L. stand for?
Center of lift, or center of pressure
22When flying, when are lift and weight equal?
In a straight and level flight
23What is the leading edge of an airfoil? (wing)
The edge of the wing that the air directly hits
24What is the trailing edge of an airfoil? (wing)
The end opposing end of the wing the wind hits where the airflow meets at the end
25What is the chord line?
The line that draws out the angle of the leading edge and trailing edge
26What is the angle of attack?
The angle the flight path line and the chord line make
27Weight is applied to the center of gravity? T/F?
True
28During unaccelerated flight, thrust is equal to drag? T/F?
True
29What are the two types of drag?
Parasite drag
(Lift)Induced drag
30What is parasite drag?
A byproduct of flying through the air, increases as speed increased
Form drag - Casued by the shape of the object, like a jeep vs porche
Interference drag - The components of the aircraft like the wing generating with the frame
Skin friction drag - Imperfection on the surface of the lift generating surface, rivets, bugs, paint chips etc.
31What is (Lift) Induced drag?
Fixed wing - Generated as soon as lift is created
Rotorcraft - Created as soon as lateral motion starts, or moving sideways
32(Lift) Induced drag decreases as speed increases? T/F?
True
33When does a stall happen?
When the airfoil reaches the critical angle of attack
Flying at too slow of a speed
The airflow is no longer laminar over the top of the wing (sticking to the top of the wing)
34What does a stall cause?
Fixed wing - The nose dropping
Rotorcraft - Doesnt happen or very few chances
35What is load factor?
The representation of the acceleration of gravity - Getting sucked into seat from accelerating
36Load factor increases with bank angle? T/F?
True
37Stall speeds do not increase with load factor? T/F
False
38What is stability?
The ability of an aircraft to return to the original flight path after being disturbed
39What is dynamic stability?
The aircrafts response ofver time when disturbed
40Which factors affect performance?
Center of gravity location
Altitute
Temperature
Humidity
Weight
41What is the "envelope"
The aft and forward CG limit of an aircraft
42To ensure that the unmanned aircraft center of gravity (CG) limits are not exceeded, follow the aircraft loading instructions specified in the
Pilot's Operating Handbook or US Flight Manual.
43The term "angle of attack" is defined as the angle between the:
Chord line of the wing and relative wind
44When operating an unmanned airplane, the remote pilot should consider that the load factor on the wings may be increased anytime:
the airplane is subjected to maneuvers other than straight and level flight.
45The angle of attack at which an airplane wing stalls will
remain the same regardless of gross weight
46If an unmanned airplane weighs 33 pounds, what approximate weight would the airplane structure be required to support during a 30° banked turn while maintaining altitude?
38lbs
47A stall occurs when the smooth airflow over the unmanned airplane's wing is disrupted and the lift degenerates rapidly. This is caused when the wing:
exceeds its critical angle of attack.
