minimum inside radius of whichever of the following is the greater:

 (i) 6 m;

           (ii) 0.83 times the D value of the largest helicopter using the area.

       (3) The touchdown and lift-off area must have a white "H" identification marking that is:

(a) located centrally within the touchdown and lift-off area circle; and

(b) aligned with the orientation of the primary helicopter landing direction; and

(c) either:

 (i) 3 m high and 1.8 m wide, with a line thickness of 0.4 m; or

 (ii) 6 m high and 3 m wide, with a line thickness of 1 m; or

           (iii) of dimensions within the range constituted by subparagraphs (i) and (ii), provided the proportions are preserved as far as possible.

8.116 Helicopter touchdown and lift-off area markings — runway type FATO area

Note   A runway type FATO area is described in ICAO Annex 14, Aerodromes, Volume II, Heliports. In Annex 14, the relevant markings are referred to as Helicopter FATO designation markings and heliport identification markings for a runway type FATO. For ICAO documents see section 1.07.

       (1) If a runway type FATO area is provided for the touchdown and lift-off of helicopters on a sealed, asphalt or concrete surface, it must be marked with an identification marking.

       (2) The identification marking must consist of a runway type FATO area designation marking, as shown in Figure 8.116 (2), that is:

(a) a white "H" marking, 9 m high and 5.4 m wide, with a line thickness of 1.2 m; and

(b) located 6 m from the commencement of the runway type FATO area; and

(c) in the form of a 2-digit number that is:

           (i) derived from the magnetic bearing of the runway type FATO area when viewed from the direction of approach; and

 (ii) rounded to the nearest 10 degrees.

       (3) If a magnetic bearing becomes a single-digit number, a "0" must be placed before it.

       (4) If a magnetic bearing becomes a 3-digit number, the last "0" digit must be omitted.

Note   For example, a bearing of 353 degrees would be rounded to 350, and the 0 omitted.

       (5) For this section:

(a) the letter H in the marking must be in accordance with paragraphs (2) (a) and (b); and

(b) the numbers in the marking must be:

 (i) the same height as the letter H; and

 (ii) the same line thickness as the letter H; and

 (iii) as far as physically possible, drawn to reflect, in form and width, the same proportions as shown
