Quick reference

Air Law - Canadian Aviation Regulations, Part IX

  • CAR Part IX covers RPAS with a takeoff weight of 250 g to 25 kg; registration with Transport Canada is required before flight.

  • Basic RPAS pilot certificate minimum age is 14; Advanced RPAS pilot certificate minimum age is 16.

  • Advanced operations are required in controlled airspace, within 30 m of bystanders, or over people; Basic operations must avoid those conditions.

  • An Advanced RPAS must have a manufacturer's safety assurance declaration; a Basic operation does not require one.

  • A pilot must not operate an RPAS while impaired by alcohol, drugs, or fatigue, or while medically unfit.

  • Advanced certification requires a written exam and a flight review; the flight review remains valid for 24 months.

  • Basic operations require VLOS, maximum 400 ft AGL, at least 3 NM from an aerodrome, and at least 30 m from people.

  • Operations outside Part IX limits, such as RPAS over 25 kg, require a Special Flight Operations Certificate.

Airspace - classes and structure, NOTAMs, controlled and restricted airspace, aerodrome and airport operations

  • Classes A through E are controlled; Class F is special use; Class G is uncontrolled.

  • An Advanced RPAS operation in controlled airspace requires authorization from the air navigation service provider before entry.

  • Class C and D control zones normally extend from the surface upward around busy aerodromes.

  • Class F restricted airspace requires permission from the controlling agency; Class F advisory airspace does not prohibit entry but requires caution.

  • A NOTAM can activate, restrict, or close airspace and must be checked before every flight.

  • Basic operations must stay at least 3 NM from an aerodrome; Advanced operations near aerodromes require authorization or coordination.

  • Control zones and terminal areas are depicted on VFR charts and must be identified during route planning.

  • In Class G airspace no ATC clearance is required, but see-and-avoid, NOTAM, and restricted-area checks still apply.

Navigation - maps and charts, coordinate systems, GPS/GNSS use, position reporting and lost-link considerations

  • VNC scale is 1:500,000; VTA scale is 1:250,000; WAC scale is 1:1,000,000.

  • At 1:500,000, 1 cm on the chart equals 5 km on the ground; at 1:250,000, 1 cm equals 2.5 km.

  • One minute of latitude equals 1 NM (1.852 km); longitude spacing decreases toward the poles.

  • GNSS position is latitude/longitude in WGS 84; chart coordinates may use NAD83, which is close but not identical.

  • GNSS altitude is ellipsoidal; chart elevation is above mean sea level; do not use raw GNSS altitude for obstacle clearance.

  • Lost-link failsafe options include hover, return-to-home, and land; the selected action must be tested and appropriate to the site.

  • Position reports can use latitude/longitude, a named landmark, or distance and direction from a known point.

  • Chart bearings are referenced to true north; convert to magnetic heading using local magnetic declination before comparing with a compass.

Meteorology - weather products and reports, wind and stability, icing, visibility, and weather hazards to RPAS operations

  • METAR is an hourly observed aerodrome report; TAF is a forecast; GFA is a graphical area forecast.

  • AIRMET advises moderate hazards; SIGMET advises severe or significant hazards; PIREP is a pilot report.

  • Density altitude rises with high elevation, high temperature, and low pressure; it reduces lift, climb rate, and battery performance.

  • Icing risk exists when OAT is 0°C or below with visible moisture; accumulation can distort props and block sensors.

  • Temperature-dewpoint spread of 2°C or less indicates likely fog or mist.

  • Unstable air favors gusty winds, turbulence, showers, and thunderstorms; stable air favors smooth conditions, haze, and fog.

  • Thunderstorms produce wind shear, microbursts, lightning, and severe turbulence; avoid associated gust fronts.

  • Wind components: headwind/tailwind along runway or route; crosswind is perpendicular; compare both to manufacturer limits.

Human Factors - situational awareness, fatigue, stress, workload, decision-making, and crew resource management

  • Situational awareness includes aircraft position, traffic, weather, people, and system status; losing it precedes most errors.

  • Fatigue reduces vigilance, reaction time, and decision quality; it increases omission errors.

  • Stress narrows attention and can cause fixation; checklists and deliberate slowdowns reduce error.

  • High workload degrades scanning and decision-making; a visual observer and task sharing reduce workload.

  • IMSAFE checks Illness, Medication, Stress, Alcohol, Fatigue, and Emotion before flight.

  • CRM requires clear role assignment, closed-loop communication, and willingness to speak up about safety concerns.

  • Complacency after routine operations can cause skipped checks; use standard checklists even for familiar sites.

  • See-and-avoid is limited by small RPAS size, blind spots, and human vision; an observer improves scan coverage.

Quick reference

Flight Operations - site survey, performance and loading, emergency and contingency procedures, visual line-of-sight and operational limits

  • Site survey identifies obstacles, people, emergency landing areas, airspace, NOTAMs, weather, and takeoff/landing hazards.

  • VLOS requires continuous unaided visual contact with the RPAS and surrounding airspace; observers assist but do not remove see-and-avoid.

  • Maximum altitude is 400 ft AGL; Basic operations also require 3 NM from aerodromes and 30 m from people.

  • Advanced operations may fly within 30 m of people or over people only with the required Advanced certificate and safety-assured RPAS.

  • Weight and balance must remain within manufacturer limits; payload reduces endurance and can shift center of gravity.

  • Cold batteries lose capacity and voltage; warm batteries to manufacturer range before flight and monitor voltage in flight.

  • Lost-link response is hover, return-to-home, or land as programmed; fly-away requires notification to ATC and authorities.

  • Emergency contingency planning includes abort criteria, alternate landing sites, emergency contacts, and battery/landing margins.

  • Preflight checks include props, battery, firmware, GPS lock, failsafe altitude, and control-link range.

Radiotelephony - radio communications procedures, phraseology, and use of frequencies in controlled airspace

  • Use standard phraseology: request, roger, wilco, affirm, negative, standby, and readback.

  • MAYDAY x3 is distress; PAN PAN x3 is urgency; both require priority handling.

  • 121.5 MHz is the aeronautical emergency frequency; use it only for distress or urgency.

  • In controlled airspace, obtain authorization before entry and monitor the assigned frequency.

  • Read back ATC clearances and instructions, especially runway, altitude, heading, and frequency changes.

  • Identify with the RPAS registration or assigned call sign and state position and intentions briefly.

  • Radio failure: leave controlled airspace, land as soon as safe, and notify ATC when able.

  • Obtain ATIS before contacting ATC to reduce frequency congestion and confirm weather and aerodrome information.
