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

Certification Specifications and Guidance Material for Heliport Design (CS-HPT-DSN) — Issue 1 · Regulation (EU) No 139/2014 · EAR revision 13 Mar 2026

IR Implementing rule

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

(a) Applicability: Where provided at a [heliport](https://avioverse.aero/glossary/easa/heliport), a flight path alignment guidance [marking](https://avioverse.aero/glossary/easa/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](https://avioverse.aero/glossary/easa/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.
