Flight Time Calculator

To calculate flight time for a pilot logbook, add the individual flight durations using hours and minutes (h:mm). You can also convert the total duration into decimal hours by dividing the total number of minutes by 60. For example, 1 hour and 30 minutes equals 1.50 decimal hours. The applicable definition of flight time and any rounding requirements depend on the regulations and logbook standards you follow. You can use the Avion Calc Flight Time Calculator above to add multiple flight legs and copy the total in both standard and decimal formats.

When a flight departs before midnight and arrives the following day, add 24 hours (1,440 minutes) to the arrival time before subtracting the departure time. For example, a departure at 22:30 and an arrival at 01:15 the next day gives an elapsed duration of 2 hours and 45 minutes. This calculation assumes both times use the same time zone and 24-hour clock.

To convert flight minutes into decimal hours, divide the total number of minutes by 60. For example, 45 minutes ÷ 60 = 0.75 hours. Some aviation logbooks use tenths of an hour, where each tenth represents 6 minutes: 6 minutes equals 0.10 hours, 30 minutes equals 0.50 hours, and 54 minutes equals 0.90 hours. However, rounding and recording requirements can vary, so follow the applicable logbook or operator guidelines.

Block time generally measures the period from when an aircraft leaves its parking position (off-block) until it reaches its parking position after the flight (on-block). Flight duration is commonly used to describe the elapsed time between takeoff and landing. These measurements are different because block time can include taxiing and other ground movements. The precise definition of flight time used for pilot records depends on the applicable aviation regulations and recording standards.

To add multiple flight legs, first convert each entry into a consistent time format, then add the hours and minutes separately. If the minutes total 60 or more, carry the extra hours into the hour total. For example, 4 hours and 80 minutes becomes 5 hours and 20 minutes. Avion Calc makes this easier by supporting h:mm, total minutes, and time interval inputs, automatically calculating the combined duration.

Yes. The Avion Calc mobile apps for iOS and Android support offline calculations, so you can calculate flight times, work with Flight Duty Period (FDP) values, and perform time arithmetic without an active internet connection. This makes the app useful when connectivity is unavailable. Always follow your operator's approved procedures and systems for official flight and duty records.
