Comprehensive safety risk assessments, hazard mitigation, and operational evaluations for non-standard aerodrome conditions and obstacle penetrations.
When terrain, urban high-rise developments, or operational constraints encroach upon standard criteria, an Aeronautical Study is the authoritative engineering framework used to assess safety risks, evaluate operational impacts, and establish defensible mitigation measures without compromising aviation safety.
GACS conducts comprehensive aeronautical studies for civil aviation authorities, aerodrome operators, and infrastructure developers worldwide. Our multidisciplinary team evaluates obstacle penetrations, displaced runway thresholds, PAPI alignment, ILS commissioning angles, and radio altimeter operating areas against ICAO safety management principles.
Our aeronautical studies combine advanced flight mechanics, safety management principles, and international criteria to solve non-standard aerodrome challenges.
Hazard identification and quantitative risk modeling for proposed towers, cranes, and buildings penetrating protected airspace.
Optimizing placement, coverage, and desired glide path angles for ILS, DVOR/DME, and Precision Approach Radar (PAR).
Calculating PAPI obstacle protection surfaces (OPS), optimal beam angles, and eye-to-wheel height compatibility.
Technical evaluations for displaced runway thresholds, runway end safety areas (RESA), and non-standard climb gradients.
Applying international safety management principles to analyze constraints and deliver regulatory-compliant solutions.
Reviewing airport physical characteristics, current IFPD, obstacle database, and stakeholder operational needs.
Quantifying intrusions into OLS, PAPI OPS, radio altimeter operating areas, and instrument flight paths.
Applying ICAO Doc 9859 risk matrices, aircraft performance tolerances, and operational margin evaluations.
Formulating operational limitations, lighting/marking requirements, and comprehensive regulatory reports.
Each study delivers defensible documentation ready for submission to regulatory authorities:
All studies are conducted in strict alignment with ICAO Doc 9859 (Safety Management Manual), ICAO Annex 14, and ICAO Doc 9157 (Aerodrome Design Manual).
