Two figures in, a clear answer out. The drone flight time calculator uses battery capacity, battery discharge, battery voltage, all up weight (auw) and watts to lift 1 kg to produce drone flight time and average amp draw, applying the standard relationship for this problem in the order the calculation actually needs it.
What Is the Drone Flight Time Calculator?
The drone flight time calculator turns battery capacity, battery discharge, battery voltage, all up weight (auw) and watts to lift 1 kg into drone flight time and average amp draw.
It is a quick way to get from the numbers you have to the number you need, without setting up a spreadsheet or reaching for a formula.
How the Drone Flight Time Works
Each result follows from the ones before it, and the calculator shows every step, so a surprising answer can be traced back to the input that caused it.
Round your inputs to the precision you actually know, and keep more precision than that in the intermediate steps.
Getting a Result You Can Trust
Run the calculation twice with slightly different inputs. A sensible calculator moves its output in proportion; a wild change points to a unit or a decimal point problem in what you entered.
Write the inputs down next to the answer. It takes a moment and it is the difference between a number you can explain and one you cannot.
A Worked Example
Working through an example, with battery capacity set to 10, battery discharge set to 5, battery voltage set to 2, the calculator returns average amp draw of 500, and drone flight time of 0.1. Substitute your own figures and the same steps produce the same kind of answer.
Frequently Asked Questions
What do I need to work out drone flight time?
Enter battery capacity, battery discharge, battery voltage, all up weight (auw) and watts to lift 1 kg. The calculator then works through the relationship and reports drone flight time and average amp draw.
What does the drone flight time actually calculate?
It takes battery capacity, battery discharge, battery voltage, all up weight (auw) and watts to lift 1 kg and converts them into drone flight time and average amp draw using the standard relationship for this problem. Each step is applied in turn, so every output is traceable back to the numbers you typed in.
How should I enter battery capacity?
Use the value you actually have, in the unit shown next to the field. Enter every value in the same unit system. The calculator assumes the figures you supply are consistent, so it cannot correct a mistake that happens before the calculation starts.
Do I have to fill in every field?
Only the fields a particular result depends on. If you leave one blank, the results that need it simply show a note instead of a number, and everything else still works.
Is the answer exact?
It is as exact as the formula and the inputs allow. The method itself is the standard one for this problem, so the only sources of error are the figures you enter and the precision you ask for.
