GM1 HPT-DSN.F.530 Final approach and take-off area perimeter marking or markers
ED Decision 2019/012/R
(a) Where a TLOF is coincident with a FATO, the TLOF marking can be used.
(b) FATO perimeter markers should be of a single colour, either orange or red, or the two contrasting colours of orange and white or, alternatively, red and white should be used except where such colours would merge with the background. A FATO perimeter marker should have dimensional characteristics as shown in Figure GM1-F-1.
