The lowest safe altitude for instrument flight within sectors of an
aid, facility or aerodrome which is published in the appropriate
approach chart’

20
Q

Missed Approach Pointtca

A

The point in an instrument approach procedure at or before which
the prescribed missed approach procedure must be initiated in
order to ensure that the minimum obstacle clearance is not
infringed

before sunrise (both times inclusive), sunset and sunrise being
determined at surface level

Radar for guidance in both azimuth and elevation

25
Q

Prevailing Visibility

A

The visibility value that is reached or exceeded within at least half
the horizon circle or within at least half of the surface of the
aerodrome. These areas could comprise contiguous or noncontiguous
sectors13535

26
Q

Runway

A

A defined rectangular area on a land aerodrome prepared for the
landing and take-off run of aircraft along its lengthon

27
Q

Special VFR Flight

A

A flight made at any time in a control zone which is Class Aairspace or made in any other control zone in IMC or at night; in
respect of which the appropriate air traffic control unit has given permission for the flight to be made in accordance with special
instructions given by that unit instead of in accordance with the Instrument Flight Rules; and in the course of which the aircraft complies with any instructions given by that unit and remains clear
of cloud and with the surface in sight

A designated IFR departure route linking the aerodrome or
specified runway of an aerodrome with a specified significant
point, normally on a designated ATS route, at which the en route
phase of a flight commences5
