"Also whilst I'm here, most schools have the Idea that for the CPL flight test the maximum amount of time for flight planning is 1hr prior to departure, does anyone know where this comes from?"
Applicants should be given the task (route and conditions) no less than 1 hour before intended commencement of the test. The operational task will be a simulated passenger carrying charter flight of not more than 4 sectors.
When presenting the task for the proposed flight, ATOs must ensure that planning the task, including performance calculations, can be achieved by the average student in an hour.
If the applicant does not complete the planning task in the allotted time, the ATO must make a discretionary decision as to the continuation of the test."
