ASAP Aeronautical PANS OPS

ASAP s.r.o. (Aeronautical Services And Procedures) is an established company with a proven record since 1998, ASAP s.r.o. has maintained a reputation for delivery of the highest quality solutions to our clients requirements on time and always within budget. Through the company’s extensive experience in aviation consultancy and our understanding of the industry we work with our clients to ensure that their objectives as well as their „all important“ goals are reached.

The company ASAP s.r.o. is based in Slovakia at the cross roads between the East and the West. Being based in Slovakia has given ASAP s.r.o. the opportunity to provide high quality aeronautical services to the aviation community.

Basically, the whole subject of instrument procedure design can be summed up in two words: „Safety and Tolerance“

An IFP (or „instrument approach“) is the method by which pilots are able to position and then land an aircraft safely in reduced visibility or to achieve conditions under which visual navigation can be undertaken, permitting a safe visual landing to be made. Approaches are classified as either precision or non-precision, depending on the accuracy and capabilities of the navigational aids (navaids) used. Precision approaches utilize both lateral and vertical guidance information. Non-precision approaches provide lateral course information only. Similar procedures exist by which pilots are able to fly safe, accurate departure profiles from airports as well.

The publications depicting IFPs graphically show the specific procedure to be followed by a pilot for a particular type of approach to a given runway. They detail prescribed altitudes and headings to be flown, as well as obstacles, terrain, and potentially conflicting airspace. In addition, they also list missed approach procedures and commonly-used radio frequencies. As may be imagined, the production of these IFPs result from the application of extremely detailed safety criteria and an iterative process that requires the application of powerful and very sophisticated computer software programs to realize the most operationally effective and, above all else, safe result.

ASAP s.r.o. has produced over 600 AIP charts for inclusion onto local AIPs. These included not only instrument approach charts but also Aerodrome chart – ICAO, Obstacle Type A chart – ICAO, parking/docking chart – ICAO etc.. ASAP s.r.o. has also converted over 300 hard copy AIP charts into a computerised electronic format.

Instrument flight procedure design and aeronautical charting Software development (PHX)

It is unusual for a private companythat is a provider of aeronautical services to have a dedicated cutting edge computer software programming section within the company. However ASAP s.r.o. has gone against the norm and has had such a computer software section within the company for the last 14 years.

The ASAP s.r.o. instrument flight procedure design and aeronautical charting software department has enabled the company to move swiftly as the situation required. If new instrument flight procedure design or  aeronautical charting software capabilities would enhance a project or enable other company departments to complete a project more efficiently, the instrument flight procedure design or aeronautical charting software is planned, designed, programmed, checked and in the hands of the relevant department within a matter of weeks. This section has created the company’s own proprietary instrument flight procedure design and aeronautical charting software “PHX”.

The ASAP PHX software for instrument flight procedure design is a „Tool based“ package. For more information on the “Tool based” philosophy of the software click here.
