Aviation Calculator

Aviation Calculator is an application design for all Aviation Pilots to help them calculate and to fill their logbook, as well as other flight time calculations like Holdover Time.

It is inspired on the Airbus A320 MCDU, and it follows its concept, rules, design and color codes. It has a few modifications just for this application purpose.

With the Flight Time function you can:

- Add and subtract times, using the MCDU scratchpad, or any inserted value in the screen, like History inputs, Total Sum and Memories.

- Correct wrong inputs in the history list, without having to start from the beginning.

- No need to use the “:” or any other separator, neither zeros at left, just insert the numbers. As simple as that!
e.g.:
For 0h01 enter just 1, 0h25 enter 25, 2h35 enter 235 and for 10h00 enter 1000.

- Leaving the app will not make you lose any data, when you come back everything is just like you left it.

- Save your totals in Memories available, and use them next time.

- Intentionally, calculations are limited to 50000 hours, it is more than a pilot needs in a lifetime.

- There is a helpful tool that is the “+24” button, it helps you to calculate time differences between different days.
e.g.:
You depart at 22h50 and land at 2h50 next day:
In the scratchpad you insert 250 followed by the “+24” button. It will automatically show 2650 and then “add” button. Insert 2250 followed by the “minus” button, and there you have the difference of 4:00.

- A simple Help page teaches you which buttons are active and their functions in the MCDU.

- Adjust screen brightness for night and day use.

- Finally, but not less important this application works on any android device you have, phone or tablet of any screen size or resolution. It will adjust to it perfectly! (Not stretching or shrinking)

With the Holdover Time function you can:

- Calculate easily the Holdover Time for de-icing/anti-icing operations.
- Table sources are from the Association of European Airlines: Recommendations for de-icing/anti-icing aeroplanes on the ground, Edition 29 - July 2014.
- The start time must be entered in hhmm format (four digits, including zeros on the left).
- Use left/right buttons to scroll option selected.
- For safety reasons the data in this function will be lost when you exit the app, to avoid suggestion errors in future use.
- Warns you when to check Lowest Operational Use Temperature of Types I, II, III, & IV Fluids (LOUT).
- Warns you when no Holdover Time guidelines exist.

NOTE: THE USE OF HOT FUNCTION DOES NOT REPLACE YOUR AIRLINE MANUAL OR EQUIVALENT. IT SHOULD BE USED ONLY AS A GUIDELINE.
