GM1 to AMC19 ATS.TR.210(a)(3) Operation of air traffic control service

AERODROME CONTROL — PRIORITY FOR LANDING

(a)An aircraft landing or in the final stages of an approach to land should normally have priority over an aircraft intending to depart from the same or an intersecting runway.

(b)If an aircraft enters an aerodrome traffic circuit without proper authorisation, it should be permitted to land if its actions indicate that it so desires. If circumstances warrant, aircraft which are in contact with the air traffic controller may be instructed to give way so as to remove as soon as possible the hazard introduced by such unauthorised operation. In no case should permission to land be withheld indefinitely.

(c)In cases of emergency, it may be necessary, in the interest of safety, for an aircraft to enter a traffic circuit and effect a landing without proper authorisation. Air traffic controllers should recognise the possibilities of emergency action and render all assistance possible.
