Airspace Geometry
This is the standard vertical limit (ceiling) of Class D airspace above the primary airport.
What is 2,500 feet AGL?
You look here to find information concerning parachute jumping sites.
What is the Chart Supplement?
14 CFR Part 107 applies to this specific type of drone operation.
What are Civil Operations?
During autonomous flight, the remote pilot must be able to do this at all times.
What is take manual control of the aircraft?
A runway labeled "08" is oriented toward this magnetic heading.
What is 080 degrees magnetic?
The normal radius of the outer area (shelf) of Class C airspace.
What is 10 nautical miles?
This specific notation indicates a Control Tower frequency on a VFR sectional chart.
What is the abbreviation "CT"?
Under Part 107, a Small Unmanned Aircraft System (sUAS) must weigh less than this amount.
What is 55 pounds?
Hazards in this airspace (MOA) often include high-volume pilot training, aerial gunnery, or abrupt maneuvers.
What is a Military Operations Area?
A pilot announcing they are "left downwind" for a runway is flying parallel to the runway in this direction.
What is the opposite direction of landing? (Context: Downwind is parallel opposite)
Without prior ATC authorization, you are allowed to fly below 400 feet AGL in this specific type of airspace.
What is Class G (or uncontrolled) airspace?
To find the active times for a Military Operations Area (MOA), you should check this part of the map.
What is the border (or margin) of the sectional chart?
This person has the final authority and responsibility for the operation of the aircraft.
Who is the Pilot in Command (PIC)?
Along an "IR" training route, military aircraft may be flying at speeds above 250 knots and at this altitude.
What is above 1,500 feet AGL?
The frequency used at a non-towered airport to self-announce positions.
What is CTAF (or UNICOM)?
This class of airspace is depicted by solid blue lines on a Sectional Chart.
What is Class B airspace?
This figure represents the minimum elevation a manned pilot should fly to clear all obstacles in a specific chart quadrant.
What is the Maximum Elevation Figure (MEF)?
To fly over people in "Category 2" or "Category 3" operations, the drone must not cause injury equivalent to this much kinetic energy.
What is 11 foot-pounds?
If you are inspecting a railroad track 7 NM North of an airport in Class G airspace at 200 feet AGL, you are in this airspace class.
What is Class G?
Runway numbers are always determined using this type of North.
What is Magnetic North?
To inspect a tower that is 1,200 feet AGL, you can fly this high above the structure (assuming you are within the 400-foot radius rule).
What is 400 feet (making the total altitude 1,600 feet)?
You see a magenta circle with a "C" inside near an airport. This tells you the CTAF is what?
What is the Common Traffic Advisory Frequency?
If a drone is produced after the compliance date and does NOT have Standard Remote ID, it can only operate here.
What is an FAA-recognized identification area (FRIA)?
A foreign registered drone can be registered in the U.S. under this condition.
What is dual registration (or if it is registered in the US)?
This specific frequency (often 122.9) is used for broadcast when no UNICOM is available (MULTICOM).
What is 122.9 MHz?
