¶ What are the airspaces?
Airspaces are 3D invisible volumes of the sky where specific rules apply for pilots and controllers. It's like a "3D puzzle" that cuts out the sky. These invisible volumes are called Airspace Classes
There are 7 Airspace Classes: A, B, C, D, E, F and G
Each classe has its own rules (altitudes, authorizations, types of flights authorized).
👉 Imagine the sky as a kind of big house: depending on which room you are flying in, you have to follow specific rules.
✈️ Key points to understand:
-
Airspace classes are the same all around the world, but they are not arranged in the same way everywhere.: For example, it would be wrong to say that all airports are in Class C airspace. It cannot be made a universal rule. In one country it can be Class C, in another it can be Class B (and it's just an example)
-
Some countries do not use all Airspace Classes: it is not uncommon to see a country without F class
-
Don't try to link them to an altitude or geographical points. These are 100% arbitrary, 100% human choices
-
Each airspace classe (each "room") has its own rules: minimum visibility, radio contact with ATC, maximum speed, or the type of aircraft allowed.
¶ 🛫 Why does it matter?
Airspaces make sure pilots and ATC follow the same rules.
For pilots, they tell you what you must do: altitude, radio, clearance, visibility.
For ATC, they define which flights must be managed and how to keep safe separation.
*this picture is only an example, please refer to your division
Imagine an aircraft taking off from Class C and climbing westbound: it will enter Class E, then cross a Class B area before continuing its climb through Class E and finally cruise in Class A.
