Blocks 4 and 5 of the FAA Form 7460-1 now show your analysis data.
Airport identifiers or "Idents" are code words for airports. Idents, like "ORD," represent airports. In this case ORD means Chicago O'Hare International Airport.
The first report produced during an analysis is the Airport Report. This reports discovers the landing facilities that are near your proposed site. This report should be the first report you review after an analysis. It provides information on Federal Aviation Regulation 77.13, "Notice Criteria." It lists the distance to the nearest point of the nearest runway.
The identifier or Ident is listed in the left most column of the report. If you need additional information about this airport go to the TERPS® program and open an airport using this 3 or 4 alphanumeric code. A window will open providing you will additional information such as Airport Reference Point data and Magnetic Variation.
For many years now the Federal Aviation Administration has had a program to survey all airports (and runways) in the National Airspace System (NAS). This program is ongoing. They increase the number of surveyed runways every 56 days. The average number of new runways added to the data is approximately 10 to 20 every two months. This data is checked by our staff for accuracy (we have found mistakes) before we accept the data into our data base. We research and fix errors. If we can not verify the data, we do not use it.
If an airport does not have data for its runways AIRSPACE® uses an algorithm to predict potential penetrations of the Horizontal and Conical surfaces. If the actual runway data is not available AIRPSACE® enters the distance to the Airport Reference Point (ARP) on the FAA Form 74601-1 in nautical miles.
Our instructor has almost 30 years of service with the FAA and has been involved in the obstacle evaluation process for over half of that time.
Federal Airways & Airspace, the creators of AIRSPACE® and TERPS®, provide training to individuals, companies, and state governments, if requested. We come to your place of business and provide training to your entire staff for one fee. We believe in training as many individuals as possible in a company so they can work together to develop your sites as fast as possible by making site selections early in the design stage. Please contact us via email (FAA@AirspaceUSA.com) if your would like additional information.
TERPS® stands for Terminal Instrument Procedures. Terminal Instrument Procedures or TERPS® surfaces are constructed from the electronic signals transmitted by ground and space based air navigation electronic equipment. These are the instrument procedures that aircraft pilots use to fly between airports and land on runways.
TERPS® surfaces are different than FAR Part 77, sub-Part C, imaginary obstacle surfaces that surround airport. These instrument surfaces can extend 10 nautical miles from a runway, where as, obstacle surfaces normally extend only 10,000 feet.
Our TERPS® Professional software displays the airport runway configuration, your proposed site, existing obstacles, and ground based electronic air navigation facilities (VOR, NDB, ILS, etc). To visually see the effects of a TERPS® surface, select the procedure from the Map menu (Draw Procedures), locate, click and hold on the runway end. Now drag the the mouse cursor in the opposite direction of the approach course and the TERPS® trapezoid will be drawn on the screen to scale when you release the mouse button. This capability is not available in the standard version of TERPS®.
New data is available every odd month. Jan, Mar, May, Jul, Sep, and Nov. In addition to new data, software upgrades are shipped at the same time.
