Aerodrome operating minima AOM are calculated by operators based on information supplied by national authorities in their AIPs. From May 2,the FAA started publishing new instrument approach plates that include an enlarged segment of airspace to protect aircraft during circling approaches.

This aviation -related article is a stub. Retrieved from ” https: Retrieved opw April The circling approach area has been expanded to provide improved obstacle protection. International Civil Aviation Organization. Table 1 shows the lowest value of visibility assumed by each method:.

Additionally, pilots not aware of the increased bank angle expected in US TERPS calculations might, in certain circumstances, stray outside the circling area due to the increased circling radius.

Such procedures are used to allow aircraft to land and take off when instrument meteorological conditions IMC impose instrument flight rules IFR. The basis for calculation of minima is usually printed on the approach plate see Further Reading: By using this site, you agree to the Terms of Use and Privacy Policy.

These values are calculated differently and therefore, may result in different AOM.

This is believed to have been a major factor in the following fatal accident, which resulted in considerable loss of life: The new airspace also offers pilots additional obstacle clearance while considering their MSL altitude above the MDA, which affects true airspeed. The boundaries of protected airspace for circling approaches are defined by arcs drawn from the threshold of each runway at an airport.

From Wikipedia, the free encyclopedia. These distances, dependent on aircraft category, are also based on the circling altitude which accounts for the true airspeed increase with altitude. Retrieved from ” https: This information typically consists of approach and departure procedures which assure safe separation between the aircraft and known obstacles located close to the intended flight path of the procedure in question.

Chapter 4 of Annex 14 to the Convention on International Civil Aviation “[establishes] a series of obstacle limitation surfaces that define the limits to which objects may project into the airspace” surrounding an aerodrome.

Prior to this all procedure design was done with pencil, tracing paper and a calculator. This is especially true in respect of Circling Approaches where the assumed radius of turn and minimum obstacle clearance are markedly different see below.

Aerodrome Design and Operations 7th ed. Please help improve this article by adding citations to reliable sources.

It is therefore essential that pilots understand these differences and are aware of the basis of calculations for all airfields at which they intend to operate, including alternates. Both systems assume a 25 kt The procedures themselves are based on obstacle clearance domains constructed using internationally accepted standards.


The latter is shown on Table April Learn how and when to remove this template message. Charts without the new designation will continue to be guided by the old, smaller-radii criteria. In the very first commercially available off the shelf instrument procedure design software conforming to ICAO document Pans-Ops was programmed.

Under the new criteria that radius will increase by 65 percent, to 2. The higher the speed of the aircraft, the larger the arc. This article needs additional citations for verification. Where buildings may under certain circumstances be permitted to penetrate the OLS, they cannot be permitted to penetrate any PANS-OPS surface, because the purpose of these surfaces is to guarantee pilots operating under IMC a descent path free of obstacles for a given approach.

As a result, circling minima at certain airports may increase significantly. Jeppesen Chart Basics – a presentation. You can help Wikipedia by expanding it. Views Read Edit View history.

B, vicinity Busan Korea, For details refer to the relevant documents listed below. Unsourced material may be challenged and removed. These surfaces may be used as a tool for local governments in assessing building development.

National authorities or operators may require adjustments to be applied to operating minima to compensate for these differences. Terminal Procedures and Jeppesen both plan to use new chart symbology to identify the updated approaches.
