When should you initiate the first Time Hack?

• A. After Before T/O checklist and Departure Brief, but before calling Tower
• B. After Takeoff
• C. At Cruise altitude
• D. After landing

Answer: (A)

Timing your flight from a defined reference point is the idea being tested. Start the first Time Hack after you complete the Before Takeoff checklist and Departure Brief, but before calling Tower. Establishing the timer at this stage gives you a precise takeoff reference to measure subsequent leg times, fuel burn, and ETA calculations. Starting the timer before you contact ATC ensures the initial elapsed time matches the actual moment you’re about to depart, keeping your navigation and planning accurate. Beginning it after takeoff would lose that baseline, waiting until cruise altitude would miss the initial climb timing, and starting after landing serves no enroute timing purpose.
