Regulations - drone registration
A small UAS registration is good for 3 years. Keep the registration information current, and update changed information in DroneZone within 14 calendar days.
Use it when: Use this when a question asks how long registration lasts, what happens after moving, or whether registration data must stay current.
Contrast: A drone should not be registered in two countries at once. Under the FAA rules, registration effectiveness ends if the aircraft is registered under the laws of a foreign country.
Open regulations module Regulations - handing off controls
A person may manipulate the controls if they have a remote pilot certificate, or if they are under direct supervision of the remote PIC and the remote PIC can immediately take direct control.
Use it when: Use this when a question asks whether someone standing with you can fly the drone, take the controller, or operate while you supervise.
Contrast: If the remote PIC is incapacitated and cannot supervise or immediately take control, a non-certificated handoff does not meet the normal Part 107 rule. A certificated backup remote PIC is the clean answer.
Open regulations module Airport ops - wind direction
For runway selection, match the runway number to the reported wind direction. Wind 130 favors RWY 13 because the aircraft points 130 degrees into the named wind direction.
Use it when: Use this when a runway-selection question gives wind direction and asks which runway to use for landing or takeoff.
Contrast: If an example arrow points toward RWY 13, read it as the reported wind direction marker, not necessarily an airflow arrow. A tailwind on RWY 13 would be wind from about 310.
Open operations module Charts - airport symbol layers
Airport symbols stack clues: color tells tower status, shape tells airport/runway type, and small extras like tick marks tell services. Blue = control tower. Magenta = no control tower.
Use it when: Use this when a chart question shows a magenta circle, runway-looking airport symbol, blue runway outline, or tick marks around an airport.
Contrast: Do not read every blue or magenta airport mark as an airspace boundary. Airport symbol color is tower status; surrounding airspace lines determine controlled airspace.
Open airspace module Airport ops - frequencies
CT is the control tower frequency. ASOS or AWOS is automated weather. UNICOM is for non-control airport advisory and service calls, such as fuel, parking, and local airport information.
Use it when: Use this when a Chart Supplement or airport listing question asks which frequency gives tower contact, weather, or airport services.
Contrast: Do not use ASOS/AWOS to talk to people. Do not treat UNICOM as ATC. At some non-towered airports, UNICOM may also be the CTAF used for traffic advisories.
Open operations module Operations - night aircraft lights
At night, steady red and green position lights mean you are seeing the front or side of the aircraft, so treat it as approaching or crossing. A steady white tail light means you are seeing the rear, so it is moving away.
Use it when: Use this when a night question asks whether a low-flying aircraft is getting closer, moving away, or crossing your path.
Contrast: Do not confuse a flashing red beacon with the steady red wingtip position light. Red is on the aircraft's left side, green is on the right side, and white is aft.
Open operations module Charts - MEF
MEF means Maximum Elevation Figure: the highest elevation in that latitude-longitude quadrangle, including terrain and vertical obstacles, rounded up to the next 100 feet MSL.
Use it when: Use this when a question asks what the large blue elevation figure in a chart quadrangle represents.
Contrast: Do not treat MEF as a controlled-airspace floor, ceiling, or the height of one specific tower. It is the worst-case elevation for the whole box.
Open airspace module Charts - lighted obstructions
A lighted obstruction is shown with small starburst or light marks around the obstruction symbol. The FAA legend labels this as an obstruction with high-intensity lights.
Use it when: Use this on sectional-chart questions asking whether an obstacle or obstruction is lighted.
Contrast: Do not confuse the light marks with the height numbers. The first number is MSL, parentheses are AGL, and the lighted symbol is a separate visual cue.
Open airspace module Airport ops - runway numbers
A runway number is the runway's magnetic direction rounded to the nearest 10 degrees. RWY 13 means about 130 degrees; the opposite end is RWY 31.
Use it when: Use this when a question asks runway direction, landing direction, takeoff direction, or which runway points most into the wind.
Contrast: The runway number is not itself a wind report. Wind is reported separately, but pilots usually choose the runway end closest to the wind-from direction.
Open operations module Charts - airport fuel ticks
Tick marks around an airport symbol mean services are available: fuel is available and the field is attended during normal working hours.
Use it when: Use this on sectional-chart questions that ask whether fuel is available at an airport based on the airport symbol.
Contrast: No tick marks means fuel is not depicted on the chart. Check the Chart Supplement for complete airport services.
Open airspace module Airspace - part-time towers
When a part-time control tower closes, the Class D surface area is no longer active. It may become Class E surface area or Class G to the overlying Class E floor.
Use it when: Use this when a question asks what happens to Class D airspace after a part-time tower closes, or asks whether the towered-airport rules still apply after hours.
Contrast: Do not assume it is always Class G. The Chart Supplement airport listing will say 'other times CLASS E' or 'other times CLASS G.'
Open airspace module Airspace - TFR checks
To identify a Temporary Flight Restriction (TFR), check NOTAMs through the FAA's official system or a NOTAM-aware flight-planning application.
Use it when: Use this when a question asks how to find temporary restrictions, VIP movement restrictions, firefighting restrictions, stadium restrictions, or other time-critical airspace changes.
Contrast: A sectional chart is not enough for TFRs because TFRs are temporary and time-sensitive. Check NOTAMs before the flight.
Open airspace module Operations - night vision
With off-center viewing at night, an object can disappear if you stare at it longer than about 2 to 3 seconds.
Use it when: Use this on night-operations questions about off-center viewing, night scanning, dim objects, or the night blind spot.
Contrast: The fix is not to stare. Look slightly beside the object and keep your scan moving with short pauses.
Open operations module Regulations - Part 107 applicability
Part 107 applies to civil small UAS operations. On the test, that answer beats broader wording like all aircraft, all drones, or recreational-only operations.
Use it when: Use this when a question asks what kind of operation Part 107 covers, or asks for the scope of Part 107.
Contrast: Recreational flyers may operate under 49 U.S.C. 44809 instead. Part 107 is the civil small UAS rule set for certificated remote pilot operations.
Open regulations module Weather - stable air
Stable air is usually smooth, but it can trap haze, smoke, or moisture near the surface, so surface visibility is often poor.
Use it when: Use this on weather questions about air stability, haze, fog, stratus layers, or reduced visibility.
Contrast: Unstable air is the opposite pattern: bumpier/turbulent, better visibility, cumulus clouds, and showery precipitation.
Open weather module Operations - hot air balloons
It can be unsafe to operate near hot air balloons because tethered anchoring cables, ropes, or lines may be present and hard to see.
Use it when: Use this when a question asks why drones should avoid hot air balloons, balloon launch areas, or tethered balloon operations.
Contrast: The trap is usually not GPS, radio interference, or airspace class. The exam wants the physical cable/anchoring-line hazard.
