GENERAL REGULATION INFORMATION
Part OPS
ANNEX IV - Operations Requirements - Aerodromes
Commission Regulation (EU) No 139/2014 of 12 February 2014 laying down requirements and
administrative procedures related to aerodromes pursuant to Regulation (EC) No 216/2008 of
the European Parliament and of the Council.

REGULATION ITEMS BY SECTION

SUBPART A AERODROME DATA (ADR.OPS.A)
Reference Description
ADR.OPS.A.005 Aerodrome data
The aerodrome operator shall as appropriate:
(a) determine, document and maintain data relevant to the aerodrome and available services;
(b) provide data relevant to the aerodrome and available services to the users and the
relevant air traffic services and aeronautical information services providers.
ADR.OPS.A.005 AMC1 Aerodrome data
(a) Data relevant to the aerodrome and available services should include, but may not be
limited to, items in the following list:
(1) aerodrome reference point;
(2) aerodrome and runway elevations;
(3) aerodrome reference temperature;
(4) aerodrome dimensions and related information;
(5) strength of pavements;
(6) pre-flight altimeter check location;
(7) declared distances;
(8) condition of the movement area and related facilities;
(9) disabled aircraft removal;
(10) rescue and firefighting; and
(11) visual approach slope indicator systems.
(b) The aerodrome operator should measure and report to the aeronautical information
services obstacles and terrain data in Area 3, and in Area 2 (the part within the aerodrome
boundary) in degrees, minutes, seconds and tenths of seconds. In addition, the top
elevation, type, marking and lighting (if any) of obstacles should be reported to the
aeronautical information services.
(c) Electronic obstacle data for all obstacles in Area 2 (the part within the aerodrome
boundary) that are assessed as being a hazard to air navigation should be provided.
(d) Electronic terrain and obstacle data should be provided for:
(1) Area 2a, for those that penetrate the relevant obstacle data collection surface;
(2) penetrations of the take-off flight path area obstacle identification surfaces; and
(3) penetrations of the aerodrome obstacle limitation surfaces.
(e) Electronic terrain and obstacle data should be provided for Area 4 for terrain and
obstacles that penetrate the relevant obstacle data collection surface, for all runways
where precision approach Category II or III operations have been established and where
detailed terrain information is required by operators to enable them to assess the effect of
terrain on decision height determination by use of radio altimeters.
(f) The aerodrome operator should establish arrangements with the Air Traffic Services
providers and the CAA for the provision of obstacles and terrain data outside of the
aerodrome boundary.
ADR.OPS.A.005 GM1 Aerodrome data
AERODROME REFERENCE POINT
(a) The aerodrome reference point should be located near the initial or planned geometric
centre of the aerodrome and normally should remain where first established.
(b) The aerodrome reference point should be measured and reported to the aeronautical
information services in degrees, minutes, and seconds.
AERODROME AND RUNWAY ELEVATIONS
The following should be measured and reported to the aeronautical information services:
(a) The aerodrome elevation and geoid undulation at the aerodrome elevation position to the
accuracy of one-half metre or foot;
(b) For non-precision approaches, the elevation and geoid undulation of each threshold, the
elevation of the runway end and any significant high and low intermediate points along the
runway, to the accuracy of one-half metre or foot;
(c) For precision approach runway, the elevation and geoid undulation of the threshold, the
