SQUARE /CIRCULAR FATOs/TLOFsAnnex 14 allows the FATO and TLOF to be square,rectangular or circular ... or in fact any shape. It is notmentioned in Annex 14 but it is generally accepted thatresearch studies show that square or rectangular FATOs orTLOFs – or those with „straight edge‟ sides - provides muchbetter visual cues, particularly on approach, to the pilotthan a circular FATOs or TLOFs. Similar at a distanceduring nighttime operations, a square or rectangularpattern of FATO or TLOF perimter edge lights provides thepilot with better visual cues than a circular pattern. Thusthere are advantages in designing heliports with a squareFATO and/or square TLOF or for the FATO and/or TLOFbeing hexagonal, octagonal or similar shaped.ICAO ‘Annex 14 Update’ Workshop – HAI HeliExpo 2010Leverton Associates, Inc

SAFETY AREAICAO ‘Annex 14 Update’ Workshop – HAI HeliExpo 2010Leverton Associates, Inc

SAFETY ZONE/AREAS• ICAO CURRENT ANNEX 14 – 0.25 D (1/4 OL) OR 3m (10ft)• FAA AC-2B: These depend to some extent on the Heliport type and whetheror not the 1 RD „TLOF is marked‟.i.e.. TLOF Marked: Private Use/PPR 1/3 RD or 10 ft. (3 m)Hospital 1/3 RD or 10 ft. (3 m)General Aviation 1/3 RD or 20 ft. (6 m)Transport Min 30 ft. ( 9 m)TLOF NOT Marked: ALL 1/2 OL (1/2D) or20 ft /30 ft (6 m/9m)(NOTE: TLOF must be marked on Transport Heliport)NOTE: 1/3 RD is approximately the same dimension as 0.25 D. Thus „safetyarea‟ is effectively the same for both current Annex 14 and „FAA‟ when theTLOF is marked. The ICAO requirements assume that the helicopter doesnot land/park near the edge of the FATO. The FAA requirements assumethe helicopter lands in the TLOF if it is marked.ICAO ‘Annex 14 Update’ Workshop – HAI HeliExpo 2010Leverton Associates, Inc
