ESSENTIAL
INFORMATION ON AERODROME CONDITIONS
(a) Essential information on aerodrome conditions is information necessary to safety in the operation of aircraft, which pertains to the movement area or any facilities usually associated therewith. For example, construction work on a taxi strip not connected to the runway-in-use would not be essential information to any aircraft except one that might be taxied in the vicinity of the construction work. As another example, if all traffic must be confined to runways, that fact should be considered as essential aerodrome information to any aircraft not familiar with the aerodrome.
(b) Essential information on aerodrome conditions should include information relating to the following:
(1) construction or maintenance work on, or immediately adjacent to, the movement area;
(2) rough or broken surfaces on a runway, a taxiway or an apron, whether marked or not;
(3) water, snow, slush, ice or frost on a runway, a taxiway or an apron;
(4) anti-icing or de-icing liquid chemicals or other contaminants on a runway, taxiway or apron;
(5) other temporary hazards, including parked aircraft and birds on the ground or in the air;
(6) failure or irregular operation of part or all of the aerodrome lighting system; and
(7) any other pertinent information.
(c) Up-to-date information on the conditions on aprons may not always be available to the aerodrome control tower or to the AFIS unit. The responsibility of the aerodrome control tower or the AFIS unit in relation to aprons is, with respect to the provision of information as described in points (a) and (b), limited to the transmission to aircraft of the information which is provided to it by the operator responsible for the aprons.
Essential aerodrome condition information, crucial for flight safety, includes hazards on movement areas like construction, surface defects, contaminants (water, snow, chemicals), temporary obstacles (parked aircraft, birds), and lighting failures. Air traffic services relay apron condition updates received from apron operators.
