A2 CofC Airspace Classification & Restrictions

Question 1

In UK airspace classification, which class of airspace is associated with the busiest controlled routes and requires ATC clearance for all aircraft including IFR and VFR flights?

Accepted Answer

Class A

Answer

Class A airspace is the most restrictive controlled airspace in the UK. All flights require ATC clearance and must be conducted under IFR. Drone operations in Class A are effectively prohibited without specific authorisation — which is extremely rare.

Question 2

What does 'Class G' airspace mean for drone pilots in the UK?

Accepted Answer

Uncontrolled airspace where drones may fly subject to open category rules and altitude limits

Answer

Class G is uncontrolled airspace. Drone pilots flying in Class G are not required to contact ATC, but must still comply with all ANO requirements including the 120 m altitude limit, distance rules, and any geographic restrictions such as ATZs or flight restriction zones.

Question 3

What is an Aerodrome Traffic Zone (ATZ) and how does it affect drone pilots?

Accepted Answer

A cylinder of airspace around an aerodrome; drones must not enter without permission from the aerodrome

Answer

An ATZ is a defined volume of airspace around an aerodrome (typically 2 nm radius, surface to 2,000 ft AAL) intended to protect aircraft in the circuit. Drone pilots must contact the aerodrome and obtain permission before entering an ATZ.

Question 4

What is a Flight Restriction Zone (FRZ) in the context of UK drone regulations?

Accepted Answer

An area around aerodromes where drone flight is restricted without specific permission or exemption

Answer

Flight Restriction Zones (FRZs) are established around licensed aerodromes to protect aircraft operations. They typically extend 5 km from the aerodrome boundary and apply from the surface upwards. Drone flight within an FRZ requires specific permission from the aerodrome or a CAA exemption.

Question 5

Which UK app or service is widely used by drone pilots to check airspace restrictions before flying?

Accepted Answer

NATS Drone Assist or Altitude Angel apps

Answer

Apps such as NATS Drone Assist and Altitude Angel (which powers several manufacturer apps) aggregate airspace data including NOTAMs, FRZs, ATZs, and temporary restrictions. Using these tools before every flight is best practice and part of responsible pre-flight planning.
