Vertical limits

4. The vertical limits of an area of airspace are defined in this Schedule as being:

(a) SFC – xx00 AMSL (see, for example, the description of YBBB/AEROPELICAN below); or

(b) SFC – xx00 AGL (see, for example, the description of YBBB/ALPHA below);

where:

xx00 is a multiple of 100.

5. If the vertical limits of an area of airspace are defined as being SFC – xx00 AMSL, then, the vertical limits of that area are:

(a) the ground level; and

(b) the plane any point on which is at a height of xx00 feet above mean sea level.

6. If:

(a) the horizontal limits of an area of airspace are defined in this Part as being a circle centred on a specified point (the reference point) on an aerodrome or aircraft landing area; and

(b) the vertical limits of that area are defined in this Part as being SFC – xx00 AGL;

then, the vertical limits of that area are:

(c) the ground level; and

(d) the plane any point on which is at a height of xx00 feet above the horizontal plane that goes through the reference point.
