Basic Test Flashcards
- Remotely Piloted Aircraft (RPA)
A navigable aircraft, other than a balloon, rocket or kite, that is operated by a pilot who is not on board.
- Small RPA
:(250 g to 25 kg)
- Remotely piloted aircraft system RPAS
A set of configurable elements consisting of a remotely piloted aircraft, its control station, the command and control links and any other system elements required during flight operation.
- Aerodrome:
Any area of land, water (including the frozen surface thereof)or other supporting surface used, designed, prepared, equipped or set apart for use, either in whole or in part, for the arrival, departure, movement or servicing of aircraft. This includes any buildings, installations and equipment situated thereon or associated therewith.
- Airport:An aerodrome for which an airport certificate is in force
- Heliport:
A heliport means an aerodrome in respect of which a heliport
- certificate issued
- Class C
Class C airspace is common around airports ranging from big international hubs to some local/regional airports as well. Class C starts at the ground and typically has a radius between 3, 5 or 7NM from the centre of the aerodrome. Factors like other airports, terrain and busyness determine how large this radius is. Airspace isn’t always round, either, for similar reasons. You can remember that class C requires a clearance.
- Class F:
These areas are marked on maps to show locations where there’s a designated activity taking place. This could be flight training, helicopter operations, aerobatics, parachuting- all kinds of things! Many of the types of activities taking place can bring aircraft all the way to the ground or very close to it, making it unsafe for UAV flight unless some coordination is taking place between pilots. No recreational or exemption flights can take place within class F and those applying for an SFOC will have to show how they plan on ensuring they can operate safely given the activities taking place. CYR class F is restricted airspace. CYRs cover things like prisons, forest fire areas, airshows, and military areas. They are no-go zones unless you’ve coordinated with the agency that controls the institution.
- Advanced operations only - to operate in controlled airspace (Classes C, D or E) you need to ask NAV CANADA for an RPAS Flight Authorization
- Control Station:
Control station device and cables (tablet, phone, laptop, or other).
- Above Ground Level, or AGL, describes the literal height above the ground over which you’re flying.VS ASL It’s the average height above standard sea level where the atmospheric pressure is measured in order to calibrate altitude.

2019
Basic Pilot and Advanced Pilot
More complex commercial operations typically require you to apply for a ____________ CERT
special flight operations certificate (SFOC)
If you RPAS is more than 25 kg you require a __________ cert
special flight operations certificate (SFOC)
Line of sight
control RPAS by seeing the aircraft in the air (unobstructed line of sight)
A separate visual observer may be used to
keep visual line of sigh for the pilot, provided there can be very clear communication between pilot and observer
VLOS
Visual line of sight
In order to operate outside of Visual line of sight you have to apply to transport canada and meet 2 requirements
1.) The probability of a RPAS collision must be no hgiher than for that of a manned aircraft
2.) Detect sense-and-avoid (DSA) capability is available
DSA defined and reuirements
Detect sense-and-avoid (DSA)
1.) Collision preventions capabilities similar to that of a human pilot including regarding right of way
2.) Sensors and actions with decision time similar to human
3.) Must detect participating and non-participating aircraft
Aerodynamics
the study of the properties of moving air and the interaction between the air and solid bodies moving through it.
Air?
like water-fluid
moving set of molecules
drag
air friction which opposes the motion of an object through the air
Parasitic drag
-is the drag caused by structure ofthe aircraft resisting the flow of air
-increases with more speed
Induced Drag
- caused as a result of lift
-downwash of air from the wing due to angle of attack
- drag decreases with speed
Two principles of lift creation are?
Newton’s laws of motion and Bernoulli’s principle
-provide fundamental understanding of how aircrafts use air to produce lift through propellers and wings
1.) Laws of motion
-Air has mass so it behaves according to newtons law
-Newtons 3rd law of motion states that for every action there is an equal and opposite rection
-It is the “action” of the aircraft on the air and the air’s “reaction” that is primary reason for flight
ex: a propeller pushes air backwards and the opposite reaction is for the plane to move forwards
4 distinct forces on an aircraft
Lift (Up)
-is the force required by an aircraft to overcome its weight and become airborne
Thrust (Forward)
- is the force that pulls the aircraft through the air usually generated by a prop
Drag (Backwards)
- is the resistance of the air to the motion of the aircraft (and all its components)
Weight (Down)
-is the force of gravity on the aircraft and its contents
How if lift generated?
as the wing pushed air downwards the air pushes the wing upwards
as the velocity of the air increases the pressure decreases
Stalls
when the angle of attack is too high air flow becomes turbulent over the wings leading to a drastic decrease in lift
-a stall can be corrected by reducing the angle of attack and/or changing the velocity of the aircraft
center of gravity
important if holding payloads because it affects stalls
air craft axis’
Axis of roll (longitudinal)
- Wings left or right
-controlled by ailerons
Axis of Pitch (lateral)
- nose up or down
-controlled by elivator
Axis of Yaw (vertical)
-nose left or right
-controlled by rudder
for any plane to turn you will need to use the ______ and the ________
rudder and aileron
most RPAS have ________ propellers
fixed pitch propellers
two types of propeller pitch
coarse (high) pitch
-greater flight speed at higher RPM
-best for cruising at long distance
-most economical
Fine (Low) pitch
-for landing and takeoffs mostly
-allows engine to develop more power
4 main flight controls on a helicopter
1.) cyclic
- joystick to move helicopter
-changes pitch of each main blade and different points of rotation
2.) collective
- lever to go up or down
-changing pitch of all main blades at the same time
3.) Anti-tourque pedals
- foot pedals to move nose left or right
-changes pitch of tail rotor
4.) Throttle
-controls engine power
Density altitude
when the air becomes less dense then the aircraft needs to work harder to gain lift
density altitude decreases with altitude and higher temps
airspeed
high airspeed requires larger turn radius
load factor
G force
- the ratio of an aircraft’s lift to its weight
-when an aircraft is flying level the load factor is 1
- when the aircraft is forced to climb or turn the load factor increases
ground effect
is essentially the added lift that can be produced because the air is pushing off the ground
gyroscopic effects
the resultant action of a spinning rotor when a deflecting force is applied to its rim
when a force is applied the resulting force takes affect 90 degrees ahead of and in the direction of motion
why helicopters have tail rotors
PARTS OF AN airfoil

Slat at the front of airfoil
Flap at the back of airfoil
critical angle of attack?

Which flying area increases directional stability?
Does low pressure generate lift on a wing?
The shape of an airplane wing generates a low pressure above the wing surface as air flows over the wing. The low pressure produces the lift that enables the plane to fly.
In a system, where energy remains constant during low pressure, speed goes _______(up/down)
up
An aircraft with contaminated skin or surface would worsen which type of drag?
skin friction
What kind of angle does coarse pitch has?
Large angle (high pitch)
stalling speed is essentially the _________ speed
minumum
If ice has accumulated on an aerofoil in flight, the stalling speed will
Increase in all flight conditions
so, you will not be able to go as slow without stalling
-it raises the minimum speed
Explain the role Flap slots play on an aircraft’s wing?
slot increase the lift and delay the stall
What is the angle of attack?
The angle between the chord line and the relative airflow
What is Bernoulli’s principle?
That the total energy is any system remains constant. In other words if one element of an energy system is increased another decreases to counter the balance
