Airspace & Flight Procedure Design

ICAO PANS-OPS compliant instrument flight procedures — from initial design through authority validation.

Airspace & Flight Procedure Design

Modern airspace is increasingly complex. Efficient flight procedure design is critical for maximising airport capacity, minimising environmental impact, and ensuring absolute obstacle clearance during all phases of flight. Altitude Nexus bridges the gap between regulatory requirements and operational efficiency.

Instrument Approach Procedures

We design all categories of instrument approach procedures including RNP APCH (LNAV, LNAV/VNAV, LPV), ILS, VOR, NDB, GNSS and PinS for heliports. Each procedure is designed per ICAO Doc 8168, optimised for obstacle clearance and documented with complete dossiers for authority submission.

  • RNP APCH (LNAV / LNAV-VNAV / LPV)
  • ILS CAT I, II, III
  • VOR, NDB & GNSS approaches
  • Helicopter PinS procedures
  • OCA/H & OAS calculation
  • ARINC 424 coding tables

SIDs, STARs & Holdings

We design Standard Instrument Departures (SIDs) and Standard Arrival Routes (STARs) optimising traffic flow while maintaining terrain and obstacle clearance. We also design holding procedures and conduct all associated airspace coordination with ANSPs.

  • SID & STAR design
  • CCO / CDO (continuous climb/descent) optimisation
  • Holding procedure design
  • NOTAM & AIP chart documentation

Airspace Design & Restructuring

We support airspace restructuring projects including Class A–G design, TMA and CTR design, route planning, and coordination with ANSPs. Complete technical documentation is provided for regulatory approval.

  • Class A–G airspace design
  • TMA / CTR / ATZ design
  • ANSP coordination support
  • Regulatory approval documentation
Airspace & Flight Procedure Design

Fast-time simulation offers a cost-effective means of quantifying and evaluating system reliability and performance. Its primary objective is to support high-level decision-making related to system changes or the introduction of new procedures and technologies. To address these needs, a broad range of current and future air traffic management (ATM) concepts are modelled, generating analytical results within short timeframes. This approach reduces data preparation effort and allows more time for in-depth comparative analysis.

Fast-time simulation

Detect current traffic hotspots, cuantify sector capacity and increase airspace management efficiency.

  • Airside Simulation
  • Groundside Simulation
  • Detect capacity bottlenecks
  • Measure operation delay (avg flight delay, taxi times, arr/dep, etc)

Regulatory Framework

  • ICAO Doc 8168 (PANS-OPS) Vol II — Construction of Instrument Flight Procedures
  • ICAO Doc 9906 — Quality Assurance Manual for Flight Procedure Design
  • EASA Part-FPD — EU requirements for Flight Procedure Design
  • ICAO Doc 9613 — Performance-Based Navigation (PBN) Manual

Powered by ASIT

We use ASIT to calculate and validate Obstacle Assessment Surfaces (OAS) for all instrument procedures, ensuring full ICAO and EASA compliance from design through submission.
