A NOTAM (Notice to Airmen) is an official notice containing information about changes to aeronautical facilities, services, procedures, or hazards that pilots must know.

In Class G airspace below 1,200 feet AGL during daytime, VFR pilots only need to remain clear of clouds with 1 statute mile visibility.

Ailerons are the primary roll control surfaces located on the trailing edge of each wing, working differentially to bank the aircraft.

Copper is an excellent thermal conductor, which is why it is used in heat sinks, cooking pans, and electrical wiring. Wood, glass, and rubber are much poorer conductors (good insulators).

Mast bumping occurs in teetering rotor systems when the rotor hub contacts the mast, typically in low-G flight, and can rapidly lead to catastrophic blade separation.

The collective pitch control raises or lowers the pitch angle of all main rotor blades simultaneously, changing the total lift generated and controlling altitude.
