11.2 Flight Time Calculation
Example: RDASS flew 14 minutes and 19 seconds. Flight Battery
required 5459[mAh] to fully charge. How much available flight time
is there? (Under similar flight conditions this battery can be flown
18 minutes and 53 seconds)
1) Convert minutes and seconds to decimal minutes
(
19 [𝑠𝑒𝑐. ]
60 [𝑠𝑒𝑐. ]
+ 14[𝑚𝑖𝑛. ] ) = 14.31 𝑚𝑖𝑛𝑡𝑒𝑠
2) Multiply the decimal minutes by 80% of battery capacity
14.31 [𝑚𝑖𝑛. ] 𝑥 7200 [𝑚𝐴ℎ] = 103,080 [𝑚𝑖𝑛 · 𝑚𝐴ℎ]
3) Divide the result from step 2 by the required charge
103,080 [𝑚𝑖𝑛 · 𝑚𝐴ℎ]
5459 [𝑚𝐴ℎ]
= 18.88 [𝑚𝑖𝑛. ]
4)
Multiply by 60 to convert decimal minutes to seconds
18.88 [𝑚𝑖𝑛. ] = (0.88 𝑥 60) + 18 = 18: 53
