To take into account the variations, we use the average value. We use average because the actual current draw varies greatly during different flight stages and depends on the mode of operation (full throttle flight draws more current than mellow flying). For this calculator, we will be measuring it in Kg.Īverage Current Draw (ACD) = ACD is the average current all the motors draw from the battery. It includes the weight of the drone itself, any added accessories, and most importantly the battery. Total Flight Weight (TFW) = TFW is the weight of the drone just before take-off. Do note that the battery size is measured in terms of its capacity (Ampare-hours) and not its size.īefore going into the formula to calculate the flight time, let’s defined a few variables that we will be using. The drone flight time calculator is a simple tool that takes into account two parameters.Ī heavy drone with a smaller battery will have shorter flight time compared to a lighter drone with a relatively bigger battery. How does drone flight time calculator work? I have tested this calculator on a few drones that I got the opportunity to fly and found this quite accurate.īelow I have explained how this calculator calculates the flight time in detail for those interested in the technical details. The tool above is a simple calculator I put together to calculate the flight time using average current draw under actual load (total weight of the drone before takeoff) and your battery capacity and takes into account what kind of motors you are using (brushed or brushless).

It is painful to lose your drone just because you ran out of battery without warning especially with most DIY self-assembled drones that lack sophisticated battery monitoring systems or smaller toy category drones like Propel Snap 2.0 that have limited software capabilities to accurately calculate battery timings. In such situations, you might want to re-calculate your drone battery life or flight time. In practice, loads change as you might want to add additional gears to your drone (prop guards, extra battery, bigger camera, etc.). Most manufacturers advertise the flight time in their drone specs, but these are not always accurate because these timings are under standard load and lab conditions. This Drone flight time calculator will help you accurately calculate your time in the air.
Drone flight time varies with manufacturer, model as well as battery condition. It makes perfect sense because drones with higher flight times give you more time in the air hence extend their usability. Thank you for your understanding.Flight time is one of the first and most important parameters you check for before buying a drone.

For this reason we are no longer able to offer our service unlimitedly free of cost. Unfortenately our costs for hosting and integrated services, especially Google Maps, have highly increased.
