  1. Press FLT, move with ▼ ▲ to the function the question needs, and press ENTER.
  2. Type each value the question gives you on its own line, and press ENTER after each one.
  3. Leave the unknown line empty. It fills itself in. Fuel is the one screen that waits for =.

The screen opens on US units. Before you type a hPa pressure, a Celsius temperature or a time in minutes, press SET UNIT on that line until it shows the right unit.

In the DGCA Air Navigation paper you may use a navigation computer such as the CX-3 and a scientific calculator without multiple memories. Meteorology allows no calculator at all, and the other papers no electronic device. You cannot borrow or share one in the hall. The same calculations with the working written out: Groundspeed and wind, Density altitude and Holding entry. Many Air Navigation chapters have free sample questions to try them on. When the presses come without thinking, sit a timed DGCA mock test or work through the DGCA question bank.

Ready for your DGCA exam.

Air Navigation has 1,922 practice questions, every one worked through. Free to start.
