CANADIAN MINIMUM NAVIGATION PERFORMANCE SPECIFICATIONS (CMNPS) TRANSITION AREA (See
map page M7):
Airspace within the CDA extending upwards from FL270, underlying the designated CMNPS airspace.
CHANGEOVER POINT:
A point along the route or airway segment between two adjacent NAVAIDS where changeover in navigation
guidance should occur.
CONTROL AREA EXTENSION:
Controlled airspace of defined dimensions within the low level airspace extending upwards from 2200 feet above
the surface of the earth unless otherwise specified. CAEs extend to the base of overlying controlled airspace. Even
if described with an ASL floor, the base of a Control Area Extension shall not extend lower than 700 feet AGL.
CONTROL ZONES:
Controlled airspace of defined dimensions extending upwards from the surface of the earth to 3000´ AAE rounded
to the nearest 100 feet, unless otherwise specified.
CONTROLLED AIRSPACE:
Airspace of defined dimensions within which Air Traffic Control service is provided.
CONTROLLING AGENCY:
The air traffic control unit which normally exercises air traffic control or provides advisory service in a given
airspace.
DANGER AREA:
Airspace of defined dimensions above international waters within which activities dangerous to the flight of nonparticipating
aircraft could take place at specified times.
