A delivery drone spends 77% of its energy not cruising

On 134 measured Matrice 100 package-delivery flights, 77% of battery energy goes to climb, hover and acceleration, and one pack buys about 1 to 3 km one way.

Cruise-only energy per metre makes a delivery drone look better than a diesel truck out to 63 to 83 km. That is what our last step in the aerolog-scaling programme found from Rodrigues et al.'s public Matrice 100 flights. This step integrates battery power over the whole flight instead.

Result (134 route flights, experiments/mission_energy/): 77% of the energy [74, 81] is not cruise. At 8 m/s whole-flight energy is 154 J/m against 60 J/m for cruise alone. With one TB48D pack (129.96 Wh from a retailer listing) at 80% usable, the one-way range is about 1 km from a regression and 2 to 3 km if cruise-only slope is combined with the measured fixed energy.

I predicted a 10 to 30% non-cruise share; that was wrong. Limits: cruise windows are under 150 m long, so the range extrapolates far past the data, and I did not check how many packs the study flew. One 3.7 kg airframe says little about a 500 kg cargo aircraft.
