RPAS Practice Questions and Answers
"over/out" - Answerno longer used but may be on the exam. Over means I am done
talking but
still expect a response, out means that no further conversation is necessary
"vortex ring state" - Answerwhen the power of a multirotor is insufficient to get it out of
the
turbulent air that its rotors cause. This results in the multirotor slowly drifting to the
ground until it regains enough lift due to ground effect
• The best way to avoid vortex ring state is by flying laterally to get out of the turbulent
air
"will comply" - Answer"wilco"
actively listen in on a conversation - Answer"monitor"
Air is ---- at higher altitudes which leads to less lift potential and shorter flight times -
Answerthinner
Aircraft stations - Answerany airliners, general aviation aircraft or unmanned aircraft in
an area.
airfoil - Answerdesigned with elongated teardrop shape that generates lift on wings and
propellors
An increase in the angle of attack will increase lift until it an aircraft reaches its critical
angle of attack
Once the critical angle of attack is passed, the additional drag caused by a steeper
angle
will outweigh the lift benefit gained
will stall when exceeds critical angle of attack, adjust to smaller angle ends stall
Airspeed - Answerthe speed an aircraft is traveling through the air
an acknowledgement from a tower you call telling you to proceed with
your transmission - Answer"Go ahead"
An aircraft flying at a greater speed will have - Answera larger turning radius
ATIS (The Automatic Terminal Information System) - Answeris an automatic recording
of weather
,reporting at the airport that can be tuned into by radio or phone that can be listened to
in many parts of Canada
Bank - Answeris the angle of roll an aircraft has maintained to achieve a turn
Bearing - Answerthe relative distance to a point (usually North)
Bernoulli's Principle - Answeras the velocity of a fluid increases, the pressure exerted by
the fluid decreases
as air passes over cambered shape like airfoil of wing, lift is generated which leads to
flight
Black dashed line - Answerrail road
Can aircrafts get icing even if temp is not < 0? - AnswerYes. The pressure differential
caused by propellers can drop the temperature of the air by a few degrees causing
precipitation or moisture in the air to freeze to the drone - catch it with listening to sound
change in motors
Can you take batteries on the plane - AnswerYou can take as many batteries aboard
with you as long as they
are under 100 Wh (watt hours). If they are over, you're limited to 2 total.
Circle made of dots - AnswerNon directional beacon (NDB)
Circle with no markings - AnswerAerodrome with no services offered, numbers are
where it is ASL and longest landing space
Circle with X in it - AnswerNo longer an aerodrome, only used for emergencies
Class C Airspace - Answer- 7 NM radius
- Airspace extends from
surface to 6600' ASL (3000' AGL)
denoted with [
Class D Airspace - AnswerAirspace extends from
surface to 8000' ASL
(6100' AGL)
denoted with [
Class E Airspace - AnswerNo information along perimeter, just dashed
Class E airspace border - Answerborder between two levels of class E airspace
, side with number E700 means it is 700 ft
if not indicated starts at 2,200 ft
Class F Advisory Airspace (CYA) - AnswerAirspace where activities occur that for safety
reasons non-participating pilots should be aware of.
M indicates military activity
anything below 6000 ft is class G airspace
Class F Restricted (CYR) - Answerin Effect from surface to 10000 ft
controllers can be find in designated airspace handbook
Clear icing - Answeris when precipitation freezes on impact (freezing rain), can lock
up the moving parts on a drone extremely rapidly so it should never be flown in
common unmanned aircraft frequencies are - Answer2.4GHz, 5.8 GHZ, and 900 MHz
could you repeat yourself? - Answer"say again"
Critical surfaces and critical surface contamination - AnswerCritical surfaces are any
surface on an aircraft that contributes to lift or is in the
downwash of that lift. Critical surface contamination is anything that gets stuck to a
critical surface and creates friction.
Cumulus clouds - AnswerCumulus clouds are vertically developed (as opposed to
stratus which develop
horizontally). They become nimbus clouds when it starts to rain. If they turn into
thunderstorms, they become towering cumulonimbus clouds (TCUs)
n
Density altitude - Answeryour pressure altitude corrected for temperature
is the altitude your aircraft will behave like it's flying at regardless of its
actual altitude above sea level
DGPS - AnswerDifferential global positioning system (DGPS) can be used to
supplement the satellite system of positioning for RPAs using
ground-based systems for triangulation
•
Difference between VNC and VTA - AnswerAll of Canada is covered by VNCs
Specific, high traffic areas are covered by VTAs
