for a perpendicular runway entry (illustrates matters)

     Figure 5.12 (4)   Calculation of intersection departure information for a non‑perpendicular runway entry (illustrates matters)

       (5) Intersection departure information must be reported as follows:

(a) RWY [runway designation] — TKOF from TWY [taxiway designation];

(b) RWY remaining [in metres and feet] — Reduce all DIST by [reduced distance, in metres and feet].

Note   Here is an example of how to record the information:
       (a) RWY 14 — TKOF from TWY A;
       (b) RWY remaining 1085 (3560) — Reduce all DIST by 360 (1181).

       (6) The code number of the OLS standard under section 7.16 for each runway must be reported in accordance with section 5.04.

Note   For the applicable runway code number, see Table 4.01 (3).

       (7) The selection of the critical obstacle must be based on:

(a) a survey of the full take-off surface in accordance with the nominated runway code number; and

(b) the applicable OLS standards specified in Chapter 7 of this MOS.

       (8) The gradient from the end of the TODA to the top of the critical obstacle within the take-off climb area must be reported as a percentage figure. However, if there is no obstacle, a value of 1.2% must be reported.

 Fences or levee banks

       (9) If a fence or levee bank is located so close to a runway strip end that the take-off gradient is greater than 5%, the take-off gradient may be reported based on the next most critical obstacle within the take-off area provided that a note is added:

(a) advising that the fence or levee bank has not been taken into account in the calculation of the TODA and STODA gradients; and

(b) giving the location and height of the fence or levee bank.

 Supplementary take-off distance available (STODA)

       (10) For a TODA having an obstacle clear gradient of more than 1.6%, the STODA must be reported for obstacle clear take-off gradients of 1.6%, 1.9%, 2.2%, 2.5%, 3.3% and 5%, up to the gradient associated with the TODA, unless the corresponding STODA for a particular gradient is less than 800 m.

Note   In calculating the STODA, care must be taken to ensure that a shielded object does not become critical for the lesser take-off distances, and that the slope of the runway is taken into account.

 Threshold elevation

       (11) For an instrument runway, the elevation of the midpoint of the runway threshold must be reported, measured in feet to an accuracy of 1 foot, based on the Australian Height Datum (AHD).

 Aerodrome obstacle charts — Types A and B

       (12) If a Type A or B chart is prepared, its currency must be reported by reference to:

(a) its date of preparation; or
