Regulation
Small unmanned aircraft systems must weigh less than this specific amount, including everything on board at takeoff.
What is 55 pounds?
This airspace typically extends from the surface to 2,500 feet AGL and surrounds airports with an active control tower but lower traffic volume.
What is Class D (Delta) airspace?
This is the minimum required flight visibility, measured from the control station, for any Part 107 flight.
What is 3 statute miles?
This aerodynamic force must be equal to or greater than the weight of the drone for it to maintain or increase altitude.
What is Lift?
This systematic approach to the mental process used by pilots helps consistently determine the best course of action.
What is Aeronautical Decision Making (ADM)?
To maintain this status, a remote pilot must keep their drone within their own vision without the use of binoculars.
What is Visual Line of Sight (VLOS)?
While most Class E airspace is controlled, drone pilots only need authorization if the Class E airspace is designated for this specific location.
What is a surface area (or Class E2)?
This type of fog forms on clear, calm nights when the ground cools rapidly and chills the air above it.
What is Radiation fog?
This term describes the maximum weight at which an aircraft can safely take off.
What is Maximum Gross Takeoff Weight?
To avoid "flyaways," a pilot should ensure this failsafe is properly configured before takeoff.
What is Return to Home (RTH)?
A Remote Pilot in Command (PIC) must report an accident to the FAA within this many days if it results in serious injury.
What is 10 days?
This type of Special Use Airspace is identified by a "P" followed by a number and prohibits all flight without specific permission.
What is a Prohibited Area?
These "Forecasts" are issued for specific airports and cover a 24 to 30-hour period.
What are TAFs (Terminal Aerodrome Forecasts)?
An increase in this—the angle between the wing's chord line and the oncoming wind—can lead to an aerodynamic stall.
What is the Angle of Attack?
This "crew" concept involves the effective use of all available resources—prioritizing communication and task management.
What is Crew Resource Management (CRM)?
A remote pilot must wait this long after a drug-related conviction before they can apply for a Part 107 certificate.
What is one year?
These are issued to restrict flights on a temporary basis to protect VIPs or ensure safety during major sporting events and accidents.
What are Temporary Flight Restrictions (TFRs)?
When warm, moist air moves over a cold surface, it creates this specific type of fog.
What is Advection fog?
This force, which opposes thrust, increases as a drone flies faster through the air.
What is Drag?
If a drone loses its link to the controller and begins to fly away, the PIC should immediately notify this agency if it enters busy airspace.
What is Air Traffic Control (ATC)?
These are issued by the FAA to allow a pilot to deviate from certain Part 107 rules, such as flying from a moving vehicle.
What are Waivers (or Certificates of Waiver)?
This non-regulatory airspace warns pilots of a high volume of pilot training or unusual aerial activity.
What is an Alert Area?
This atmospheric condition occurs when the temperature increases with altitude, often trapping smoke and dust near the ground.
What is a Temperature Inversion?
This document, provided by the manufacturer, contains critical information on the UAS's weight limits and performance charts.
What is the Pilot’s Operating Handbook (POH)?
Part 107 pilots are prohibited from flying if they have this "condition," which can be caused by stress, lack of sleep, or illness.
What is Fatigue?
Maximum altitude you can fly if you are 50 feet away from a structure that is 150 feet tall.
What is 550 feet Above Ground Level (AGL)?
On a sectional chart, a magenta vignette (shaded edge) indicates that Class E controlled airspace begins at this altitude above the ground.
What is 700 feet AGL?
On a METAR, the code "BR" indicates this specific weather condition that can reduce visibility.
What is Mist?
In a steep turn, this "factor" increases, effectively making the aircraft feel heavier and requiring more power to maintain altitude.
What is Load Factor?
This term describes the hazardous attitude of a pilot who feels that "it won't happen to me."
What is Invulnerability?
