2.1. Flight Time

---

Quick Theory

Hover time is the maximum time for stationary flight, calculated using the following formula:

$t_{hover} = 60 \times \frac{P_{hover}}{V_{avg} \times C_{Ah}} \times 0.8$

Symbol	Description	Unit
$t_{hover}$	Hover Time	minutes
$V_{avg}$	Average Pack Voltage	V (Volts)
$C_{Ah}$	Battery Capacity	Ah (Ampere-hours)
$P_{hover}$	Hover Power	W (Watts)

The Flight Time Calculator offers Beginner, Standard, and Advanced options for users to choose from.

Regardless of the option selected, the flight time calculation results provide the following information:

• Hover Time [min]
• Cruise Time [min]
• Maximum Flight Distance [km]: Assumes no communication range limitations; actual flight distance may be limited by communication equipment
• Battery Capacity [Wh]
• Reliability and Design Risk
