You are planning to conduct an IFR flight in OZY from Mackay to Longreach via Dysart and Barcaldine. The area forecast indicates BKN cloud with a base of 2500 feet throughout and a freezing level of 5500 feet
Choose one answer.
a. the flight may be planned at any level providing you do not carry passengers
b. the flight may be planned providing you do not cruise above 6000 feet
c. the flight may be planned providing you remain below the freezing level
d. the flight may not be planned
The correct answer was d.
The highest LSALT is 5000, therefore why can't you plan to fly at a non-standard 5000 feet (instead of A060) as this will keep you 500 feet below the freezing level?

Hi Andrew,
Check out this reference: AIP ENR 1.7 3.2 (b) (emphasis on the word "must")
Therefore, you cannot plan to cruise at a non-standard 5000' for this route. If you need to change to a non-standard level while underway that's different. If, due pressures of weather for example, you can work with ATC on getting a new level. However, you can't take-off knowing you won't be able to oblige the regs.
