- Nota adicional1
- TERPS is used by the procedure designer to determine a lateral path that is usable by a wide variety of aircraft types, and establishes a clearance plane that aircraft must be able to stay above to fly the procedure.
- Contexto
- ATC may establish a minimum vectoring altitude (MVA) around certain airports. This altitude is based on terrain and obstruction clearance and provides controllers with minimum altitudes to vector aircraft in and around a particular location. However, it may be necessary to vector aircraft below this altitude to assist in the efficient flow of departing traffic. For this reason, an airport may have established a Diverse Vector Area (DVA). DVA design requirements are outlined in TERPS and allow for the vectoring of aircraft off the departure end of the runway below the MVA. The presence of a DVA is not published for pilots in any form, so the use of a textual ODP in a DVA environment could result in a misunderstanding between pilots and controllers. ATC instructions take precedence over an ODP. Most DVAs exist only at the busiest airports.
- The OEI net takeoff flight path is unique for each airplane type and is assessed on each takeoff for the required obstacle clearance directly against those obstacles located beneath the OEI flight track and within the prescribed lateral distance from the flight path centerline. TERPS, on the other hand, provides a required climb gradient that represents a surface that the aircraft’s all-engines-operating climb profile must remain above throughout the IFR climb until reaching the en route environment.
- The criteria for development of Terminal Instrument Procedures (TERPS), within the Federal Aviation Administration (FAA), are the responsibility of the FAA Flight Procedure Standards Branch, AFS-420 (and its predecessors). Much of the analytical work of the branch is performed by the Flight Operations Simulation and Analysis Branch, AFS-440. Both branches are part of the FAA Flight Standards Service.
