CS HPT-DSN.F.620 Flight path alignment guidance marking

(a)Applicability: Where provided at a heliport, a flight path alignment guidance marking (or markings) should indicate the available approach and/or departure path direction(s).

(b)Location: The flight path alignment guidance marking should be located in a straight line along the direction of approach and/or departure path on one or more of the TLOF, FATO, safety area or any suitable surface in the immediate vicinity of the FATO or the safety area.

(c)Characteristics:

(1)A flight path alignment guidance marking should consist of one or more arrows marked on the TLOF, FATO and/or safety area surface, as shown in Figure F-6. The stroke of the arrow(s) should be 50 cm in width and at least 3 m in length. When combined with a flight path alignment guidance lighting system, it should take the form shown in Figure F-6, which includes the scheme for marking the ‘heads of the arrows’, which are always of the same size, regardless of the stroke length.

(2)In the case of a flight path limited to a single approach direction or a single departure direction, the arrow marking may be unidirectional. In the case of a heliport with only a single approach/departure path available, one bidirectional arrow is marked.

(3)The markings should be in a colour, preferably white, which provides good contrast against the background colour of the surface on which they are marked.
