The correct option is (c) 18,000 feet msl.
When climbing to cruising flight level the altitude should be 18,000 feet msl.
What is pressure altitude?
- When an altimeter is set to 29.92 in Hg, the stated height is called Pressure Altitude (1013 hPa in other parts of the world).
- High-altitude flight and estimations of aircraft performance are its main applications.
- "Pressure altitude compensated for nonstandard temperature fluctuations" is the formal definition of density altitude.
- All aircraft operating at altitudes more than 18,000 feet MSL must have their altimeters adjusted to 29.92 inches.
- This implies that all aircraft flying in the flight levels will always have their altimeters set to the same altitude in order to keep them apart and clear of one another.
