... but aerial work does not require factoring.
I have been reliably informed that, following the forthcoming rule changes, the "airwork" category will no longer exist (or will not be available to aeromedical operators).
The aeromedical operators will then have to operate to charter standards, which require the 1.67 landing distance factor for aircraft above 5,700 kg MTOW.
... if you knew the development plans for Jandakot airport ...
If there are any plans to extend the runways, then they are keeping them secret. The website (
www.jandakotairport.com.au) lists their current development plans, but these are limited to food distribution facilities.
If you know of other plans, please tell.
