Revision as of 20:36, 18 June 2023

To fly a drone commercially, and to get approvals for non-standard flights, you must operate under Part 107 rules (ie you must have that certification).

To fly a drone that weighs more than 0.55lb, you must register it with the FAA. The FAA requires that the drone broadcast a Remote ID. You must include that when registering your drone, unless you register it as recreational.

NOTE It may be that a ham radio license is required for DIY FPV drone flying.

Allowed Materials

Allowed Materials

All models of aviation-oriented calculators may be used, including small electronic calculators that perform only arithmetic functions (add, subtract, multiply, and divide). Simple programmable memories (which allow addition to, subtraction from, or retrieval of one number from the memory) are permissible. Also, simple functions, such as square root and percent keys, are permissible. Applicants may use scales, straightedges, protractors, plotters, navigation computers, blank logsheets, holding pattern entry aids, and electronic or mechanical calculators that are directly related to the test. For more detailed information, please consult guide.

Prohibited Materials

Applicants for airman knowledge tests may not take any written materials (either handwritten, printed, or electronic) other than the supplement book provided by the proctor into the testing area. The use of magnetic cards, magnetic tapes, modules, computer chips, or any other device upon which prewritten programs or information related to the test can be stored and retrieved is prohibited. Applicants are not allowed to bring personal writing utensils into the testing room; any required writing utensils will be provided by the proctor and collected at the conclusion of the test.

Recurrent Education

If you have a Remote Pilot Certificate, you are required to have completed one of the following online training courses within the previous 24 calendar months to operate UAS under part 107:

Anyone who holds a part 107 remote pilot certificate (regardless of aeronautical knowledge recency):

   Complete the Part 107 Small UAS Recurrent (ALC-677) online training course (no cost)

Part 107 remote pilots who are also certificated with a current flight review under part 61:

   Complete the Part 107 Small UAS Recurrent (ALC-515) online training course (no cost)

You can read the Remote Pilot –Small Unmanned Aircraft Systems Airman Certification Standards (PDF).

Practice Exams > (bottom of list) Unmanned Aircraft General - Small (UAG) > Select

Gruelling 45 questions that will take over an hour, very educational to understand what the hell to study... you might want to grade yourself as you go, they will email the results at the end but it is a bit flaky.

Also see Recurrent Ed for the sample test available there.

More resources, so so many more...

AND LOTS MORE! Hard to navigate!

Test 107 Q&A

Latitude and Longitude

Measurement from 0-360 degrees, 0-60 minutes, 0-60 seconds.

Latitude: 0 degrees at equator to +90 degrees N at north polar cap and -90 degrees S at south polar cap. US is between

Longitude: 0 degrees at Greenwich, England to +180 degrees E / -180 degrees W.

AGL vs MSL

Mean Sea Level (MSL) is absolute height above standard sea level. Most common. Used to calculate atmospheric pressure, eg.

Above Ground Level (AGL) is the distance from ground to height.

https://www.dronepilotgroundschool.com/kb/what-is-the-difference-between-agl-and-msl/

What is a temperature inversion?

Stable air masses of cooler air trapped by warmer air above it.

Causes clear skies, calm wind, dew/fog, horizontal smoke patterns,

https://www.weather.gov/media/lzk/inversion101.pdf

What is high density altitude?

On a hot, muggy day, the air becomes "thinner" or less dense, and its density at a pilot's location is equivalent to a higher altitude in the standard atmosphere. Thus the term "high density altitude."

Reduced power, thrust, lift, less responsive aircraft.

https://www.weather.gov/zse/HighDensityAltitude

What is a moist unstable air mass?

An unstable air mass is characterized by warm moist air near the surface and cold dry air aloft.

Results in clear air, turbulence, precipitation, cumuliform clouds.

Lat/Long question

What airport is at 47 40 N 101 26 W?

At first (THIS IS WRONG), this looks fucked up bc "Shemchenko" is under that point, if you assume the unmarked line south of 48 degrees is the next degree (47).

But you should not look at unmarked lat/long lines and assume they are the next degree. Instead, COUNT THE TICKS, they are each ONE DEGREE, and 5 and 10 are marked out with bigger ticks. How tf you supposed to know that? This video helps.

Airspace ceilings and floors

What is the floor of the Savannah Class C airspace at the shelf area (outer circle)? 1300 feet AGL | 1300 feet MSL | 1700 feet MSL

This video is gold. God damn it is the PURPLE NUMERATOR/DENOMINATOR NUMBER on the chart, ALWAYS IN MSL unless it is in (PARENTHESES) then it is AGL - in hundreds of feet! crazy shit...

41

13

Airspace class B is BLUE SOLID LINE.

Airspace class C is RED SOLID LINE.

Airspace class D is BLUE DOTTED LINE. Ceiling is in dashed box in hundreds of feet!

Airspace class E is RED DOTTED LINE.

METARS

METARS fig 12 conditions at Midway KMDW? Sky 700 feet overcast, vis 1-1/2sm, rain

Olga's video explains.

SPECI KMDW 121856Z 32005KT 1 1/2SM RA OVC007 17/16 A2980 RMK RAB35

SPECI: METAR if no change, SPECI if changed from standard)
KMDW: the airport
121856Z: time/date, 12 = date, 1856Z = UTC 24-hr time
32005KT: 320 wind direction (0 is north?), 05KT = 5 knots
  Gusting example 11012G18KT: 110 wind dir, 12 knots wind dir, G18 gusting to 18 knots
1 1/2sm: visibility, you can see 1.5 statute miles
RA: type of weather, RA = rain, BR = mist, DZ = drizzle; +/- = heavy/light
OVC007: cloud coverage, OVC = overcast, BKN = broken; 007 = clouds at 00700 feet
17/16: temp/dewpoint
A2980: altometer barometric pressure 29.80 inches of mercury
RMK: remarks (additional info), RAB35 = rain started 35min after the hour

Runway descriptions

Fig 26 area 2: Cooperstown While monitoring a CTAF frequency, an aircraft announces they are  "midfield left downwind to runway one-three." Where is the aircraft relative to the runway?
east of runway | south | west

Olga explains.

THIS IS FUCKED. Proceed carefully and diligently and you will get it.

GIVEN:

  • INFERRED after studying this: Typically, aircraft liftoff and land AGAINST THE WIND.
  • CTAF: common traffic advisory frequency (plane to plane radio when there is no tower)
  • For compass degrees, NORTH IS ZERO, roll right, back around to zero as you come back up and to the right on the compass wheel.

one-three: Runway numbering like 27 means 270 degrees. You don't say 27, you say two-seven. YOU LAND GOING IN THIS DIRECTION. REPEAT THIS DESCRIBES LANDING, NOT TAKEOFF. For example, you fly east to land on runway nine, and west to land on runway two-seven.

left: Left hand traffic pattern is standard. You take left-hand turns through the legs (see next part).

downwind: Downwind means they are following the downwind leg. The Downwind leg is the leg for landing, opposite of the final leg for taking off. Land on it, then you take the base leg to the final leg. And you have to combine this with left/right hand traffic pattern. Left-hand says the turns are all left-hand turns. On take-off, the same designations for landing still remain I guess? THAT IS SOME FUCKED UP SHIT. lolz.

Midfield = halfway down the runway.
