Aerodrome Standards at a Remote Helipad
You are asked to support a new offshore helicopter operation using a remote inland helipad that has never been licensed. The helipad is a 20 m x 20 m concrete square with a single wind sock, no markings, a 1.2 m high fence 5 m from the edge of the touchdown area, and an approach path that passes over a line of 12 m trees 60 m from the pad. The operator wants to begin night operations within three weeks using the H125. The local authority has asked whether the site meets aerodrome standards and what oversight applies. You are not an aerodrome inspector, but you have been asked for a technical opinion as the maintenance engineer familiar with the aircraft.
1. Identify the aerodrome-standard deficiencies you can see, and explain why each matters for the H125.

Several deficiencies are apparent. The touchdown/positioning area is small for the H125's footprint and leaves no clear obstacle-free area beyond it; standards require a defined FATO with a safety area around it. The 1.2 m fence only 5 m from the edge intrudes into the obstacle limitation surfaces and would be a collision hazard in a steep or offset approach. The trees 60 m out on the approach path penetrate the approach surface and reduce the available climb gradient for a night approach. There are no markings, so at night there is no visual cue for the TD/positioning area, and a single wind sock with no lighting gives no wind information after dark. These are not cosmetic: each reduces the margin for error in exactly the phase where the H125 has least performance reserve.
2. Explain the relationship between aerodrome standards, licensing and safety oversight, and who is responsible for what.
Read the worked answer
Aerodrome standards (in this jurisdiction set out in the ANOs and CAD circulars, consistent with ICAO Annex 14) define the physical and visual requirements. Licensing or certification is the regulator's formal acceptance that a site meets those standards; oversight is the continuing process of surveillance and change management. The operator is responsible for ensuring the site it uses is suitable and, where required, licensed. The aerodrome operator is responsible for maintaining standards and reporting changes. The regulator grants the licence and conducts oversight. Your role is advisory: you can identify deficiencies and recommend that the operator obtain a proper aerodrome assessment before committing to the site.
3. What would you recommend before any night operations begin?
Read the worked answer
Recommend a formal aerodrome assessment against the applicable standards before scheduling. That should cover obstacle limitation surfaces, FATO and safety area dimensions, markings and lighting, wind indication, and an approach/departure procedure that respects the tree line. The fence should be relocated or the safety area redefined. Night operations require lighting and marking that this site lacks. Until the assessment is complete and any licence obtained, the operator should not commit to the three-week timeline; the timeline is a commercial wish, not a safety input.
