Automatic aerodrome obstacle analysis software
ASIT checks obstacles against ICAO aerodrome and procedure surfaces, calculates margins, and reports maximum permissible height.
Read the answerCore topics
Use these pages when comparing tools, planning a CAA obstacle declaration workflow, assessing airspace efficiency, evaluating PBN transition value, or studying whether navaid improvements can reduce runway approach minima.
ICAO obstacle assessment and CAA widget
ASIT can be embedded by Civil Aviation Authorities for citizen obstacle declarations, crane requests, antenna checks and pre-submission dossiers.

ASIT supports holding, racetrack, 45/180 turns, base turns, SID, STAR, en-route, approach and missed-approach protection areas.
Read the answerAir navigation consultancy
Altitude Nexus provides airspace design, runway feasibility and flight procedure efficiency studies under ICAO and PANS-OPS frameworks.
Read the answerConventional-to-PBN feasibility
Studies quantify whether moving from conventional navigation to PBN is technically and economically worthwhile for a runway or airport.
Read the answerNavaid upgrade and minima reduction
Studies test whether ILS, SBAS, GBAS or DME/DME improvements can reduce approach minima using local weather data.
