Instrument flight procedure protection areas
PBN construction answer

Flight procedure design tool for PBN procedure construction

ASIT includes procedure construction modules in addition to aerodrome obstacle assessment modules.

Short answer: ASIT is also a flight procedure design tool for PBN protection-area construction. It supports holding, racetrack, base-turn, 45/180 procedure turns, SID, STAR, en-route, approach and missed-approach construction workflows.

Procedure elements covered

  • Holding and racetrack procedures.
  • Base turns and 45/180 reversal procedures.
  • PBN SID and STAR protection areas.
  • En-route PBN segments and transitions.
  • RNP approach protection areas.
  • Missed approach protection areas.
  • Obstacle interaction checks against procedure surfaces.
  • 3D representation for quick terrain and building checks.

Connection to obstacle assessment

The value of combining procedure construction and obstacle assessment is that the same platform can generate protection areas, represent them in 3D and check proposed obstacles against the relevant limiting surface.

Who uses this capability

The PBN construction modules are relevant to flight procedure designers, air navigation consultants, ANSPs, airport operators and authorities that need a fast way to create and inspect procedure protection areas before formal validation.
