Jandakot Airport's Preliminary Draft Master Plan (PDMP) includes provisions for a new runway for circuit training.
Runway 12L/30R, which was first proposed in 1986, is planned to be 990 m x 18 m, and is intended to perform the same role as 06R/24L: day circuit training.
"Provision of the fourth runway will not significantly add to the airport’s overall capacity potential," the PDMP admits.
"The fourth runway will add to efficiency and regularity by providing an equivalent level of capacity in any wind condition, with both a primary runway and dedicated parallel training runway that can be used.
"This will be of significant benefit to the flying training schools that can currently be forced to curtail training activities when the 12 or 30 directions are in use due to the capacity restriction of a single runway operation."
The PDMP also proposes to extend the re-named 12R/30L to 1508 m from the existing 990 m to enable jet operations and to accommodate "... some of the aircraft considered for future use."
Distance between the two runway centrelines is proposed to be 213 m.
The PDMP can be downloaded from the Jandakot Airport website and is open for public comments until 15 November.
