| Category 1 flight over people | The drone weighs 0.55 lb or less and has no exposed rotating parts that would cut skin on impact. | 14 CFR §107.110 |
Airspace
| Topic | What to know | Source |
|---|---|---|
| Class B airspace | Generally the surface to 10,000 ft MSL around the busiest airports, shaped like an upside-down wedding cake. ATC authorization required. | Remote Pilot Study Guide, Ch. 2 |
| Class C airspace | Generally the surface to 4,000 ft above the airport: a 5 NM core and a 10 NM shelf from 1,200 ft. ATC authorization required. | Remote Pilot Study Guide, Ch. 2 |
| Class D airspace | Generally the surface to 2,500 ft above the airport elevation around a towered airport. ATC authorization required. | Remote Pilot Study Guide, Ch. 2 |
| Where does Class E usually begin? | 1,200 ft AGL in most places; the surface or 700 ft AGL in others. Usually no authorization needed, except the surface area around an airport. | Remote Pilot Study Guide, Ch. 2; 14 CFR §107.41 |
| Class G airspace | Uncontrolled airspace, from the surface up to the base of the overlying Class E. No ATC authorization needed. | Remote Pilot Study Guide, Ch. 2 |
| How is a temporary flight restriction (TFR) issued? | By a Flight Data Center (FDC) NOTAM. Check NOTAMs and TFRs before every flight. | Remote Pilot Study Guide, Ch. 2 |
| Military training route numbers | Four digits (VR1207): no segment above 1,500 ft AGL. Three digits (VR207): at least one segment above 1,500 ft AGL. | Remote Pilot Study Guide, Ch. 2 |
| CTAF | Common Traffic Advisory Frequency: where pilots self-announce at airports without an operating tower. With no UNICOM or FSS, it is MULTICOM, 122.9. | Remote Pilot Study Guide, Ch. 7 |
| The usual UNICOM frequency | 122.8, but always check the Chart Supplement for the airport. | Remote Pilot Study Guide, Ch. 7 |
Weather
| Topic | What to know | Source |
|---|---|---|
| What is a ceiling? | The lowest layer of clouds reported as broken (BKN) or overcast (OVC), or the vertical visibility (VV) into an obscuration. | Remote Pilot Study Guide, Ch. 3a |
| TAF coverage | A forecast for the 5 statute mile radius around an airport, valid for 24 or 30 hours and updated four times a day. | Remote Pilot Study Guide, Ch. 3a |
| Reading wind in a METAR or TAF | Direction it blows from, in degrees true, then speed in knots. G marks gusts: 16015G25KT is from 160° at 15 knots gusting 25. | Remote Pilot Study Guide, Ch. 3a |
| Stable air | Stratiform clouds and fog, continuous precipitation, smooth air, and fair to poor visibility in haze and smoke. | Remote Pilot Study Guide, Ch. 3b |
| Unstable air | Cumuliform clouds, showery precipitation, rough air (turbulence), and good visibility outside blowing obstructions. | Remote Pilot Study Guide, Ch. 3b |
| Microburst | A downdraft 1 to 2 miles wide that lasts about 5 to 15 minutes and can produce downdrafts of up to 6,000 ft per minute. | Remote Pilot Study Guide, Ch. 3b |
| Temperature inversion | Temperature rises with altitude. Expect smooth, stable air near the ground with poor visibility in the layer. | Remote Pilot Study Guide, Ch. 3b |
| Frost on the drone | Clean it all off before flight. Frost disrupts airflow over the wing, cutting lift and adding drag. | Remote Pilot Study Guide, Ch. 3b |
| Thunderstorm life cycle | Cumulus (updrafts), mature (updrafts and downdrafts; every hazard is at its worst), then dissipating (downdrafts). | Remote Pilot Study Guide, Ch. 3b |
Loading and performance
| Topic | What to know | Source |
|---|---|---|
| Load factor in a level 60° banked turn | 2 G. The structure carries twice the aircraft weight. | Remote Pilot Study Guide, Ch. 4 |
| What does a higher load factor do to stall speed? | It raises it, so stalls can happen at seemingly safe speeds in steep turns. | Remote Pilot Study Guide, Ch. 4 |
| High density altitude | Thin air, from high elevation, low pressure, high temperature or high humidity. Performance goes down. | Remote Pilot Study Guide, Ch. 3b |
| Over max weight or CG out of limits | Overweight compromises the structure and hurts performance; a center of gravity outside its limits makes the aircraft hard to control. | Remote Pilot Study Guide, Ch. 4 |
Operations
| Topic | What to know | Source |
|---|---|---|
| IMSAFE | Illness, Medication, Stress, Alcohol, Fatigue, Emotion: your fitness check before each flight. | Remote Pilot Study Guide, Ch. 9 |
| PAVE | Pilot, Aircraft, enVironment, External pressures: the four risk categories to check before a flight. | Remote Pilot Study Guide, Ch. 10 |
| Starting a new medication | Wait at least 48 hours after the first dose before flying, to make sure it does not affect you. | Remote Pilot Study Guide, Ch. 9 |
| Scanning for traffic | Scan in about 30° sectors, stop no longer than 2 to 3 seconds each, and overlap each stop by 10°. | Remote Pilot Study Guide, Ch. 9 |
| Antidote for anti-authority | "Follow the rules. They are usually right." | Remote Pilot Study Guide, Ch. 10 |
| Antidote for impulsivity | "Not so fast. Think first." | Remote Pilot Study Guide, Ch. 10 |
| Antidote for invulnerability | "It could happen to me." | Remote Pilot Study Guide, Ch. 10 |
| Antidote for macho | "Taking chances is foolish." | Remote Pilot Study Guide, Ch. 10 |
| Antidote for resignation | "I'm not helpless. I can make a difference." | Remote Pilot Study Guide, Ch. 10 |
