PBN and Procedure Design | Training

Instructor-led Training

Our designers, instructors, training material, and software are world-class. Aeropath holds certifications from multiple jurisdictions and is a contributing member to the ICAO Instrument Flight Procedures Panel (IFPP). We have received ICAO recognition for PBN and conventional procedures, and our practices are aligned with the latest ICAO Standards and Recommended Practices (SARPs).

We offer in-person and virtual instructor-led training options from basic to advanced. We also offer the ability to customise the course content to meet your learning requirements, offering you a practical and cost-effective solution for your specific training needs.

M-1 | General Criteria and Conventional Procedures

The course is based on PANS-OPS ICAO Doc 8168 Volume II Construction of Visual and Instrument Flight Procedures; it describes the essential areas and obstacle clearance requirements for the achievement of safe, regular instrument flight operations.

Prerequisites: Geodesy for procedure designers; if you are not sure we have a free self-assessment test.

Duration: 4 weeks

M-2 | Performance Based Navigation (PBN) Procedures & BARO-VNAV

This course explains the components required for the construction of RNAV instrument flight procedures based on the Global Navigation Satellite System (GNSS) and BARO-VNAV procedure design criteria.

Baro-VNAV approach procedures are classified as APV procedures — they utilise a DA/H and not an MDA/H, and neither a FAF nor a missed approach point (MAPt) is identified. They use obstacle assessment surfaces similar to those for ILS, but based on the specific lateral guidance system.

Prerequisites: Knowledge of General Criteria and Conventional Procedures.

Duration: 3 weeks


  • PBN Introduction and RNAV Principles
  • RNAV — Arrivals
  • RNAV — Final Segment
  • RNAV — Intermediate and Initial Segments
  • RNAV — Missed Approach
  • Terminal Arrival Altitude
  • RNAV Departure within transition
  • RNAV Holding Pattern
  • Proposed changes to PANS-OPS criteria
  • Practical application
M-3 | RNP-AR Navigation (Doc 9905) & BARO-VNAV

This course covers approaches with vertical guidance (APV) including the RNP-AR and a revisit of the Baro-VNAV procedure design criteria.

Required Navigation Performance Authorisation Required (RNP-AR) APCH operations are classified as approach procedures with vertical guidance (APVs). This type of operation requires a positive vertical navigation (VNAV) guidance system for the Final Approach Segment (FAS).

Prerequisites: Knowledge of General Criteria, Conventional Procedures and Performance Based Navigation.

Duration: 1 week


  • RNP AR General Criteria
  • RNP AR — Arrivals
  • RNP AR — RNP Final Segment
  • RNP AR — Intermediate and Initial Segment
  • RNP AR — Missed Approach
  • RNP refers to both advanced and and authorisation required procedures
  • Practical application
M-4 | Helicopters (Point in Space) Procedures

A specialised course that covers the general criteria and area navigation (RNAV) approach procedure applicable to helicopters only.

It also covers the Point in Space approach and departure procedures consisting of an instrument segment followed by a visual segment or vice versa.

Prerequisites: Knowledge of General Criteria, Conventional Procedures and Performance Based Navigation.

Duration: 1 week


  • Helicopter Criteria and Procedures
  • Point in Space Approaches
  • Point in Space Departures
  • HAS Diagram
  • Practical application
M-5 | PANS-OPS Recurrent Course

  • Future developments
  • Customer-specific requirements
  • PANS-OPS proposed changes
  • Forum discussion
M-6 | Obstacle Assessment and Management

This course provides airport operators or obstacle control personnel the necessary skills to evaluate aerodrome obstacles from a practical perspective.

It describes different methods to efficiently evaluate obstacles within the vicinity of the airport, including the straight segments of published flight procedures.

Prerequisites: Background in Annex 14 / PANS-OPS.

Duration: 1 week
