ICAO Doc 9261:2020

Please note, this edition addresses design and operations for heliports at a range of offshore installations and vessels.  Guidance for heliport design and operations in the onshore environment is still in development and will be included in a future edition.
The Fourth Edition of the Heliport Manual (Doc 9261) provides guidance for the implementation of the Annex 14 - Aerodromes, Volume II - Heliports. The manual consists of two parts: part I addresses design and operations for heliports at a range of offshore installations and vessels; and part II, which is currently under development, will provide guidance for heliport design and operations in the onshore environment. This new edition has taken into account the substantial development of Standards and Recommended Practices (SARPs) incorporated into Annex 14 in recent years, as well as the equipment, technology and best practices now used in the heliports arena.
