September 15, 2017, ©. Leeham Co: Last week we compared the energy economics of our 10-seater electric commuter to an equivalent commuter with gas turbine power.
Now we dig a bit deeper in the operational costs of the two aircraft. Is the electric commuter cheaper to operate over short sectors than a gas turbine driven variant? For the energy costs, it could be the fact. What about other operational costs?
The commuter designs we discuss would be similar to the Zunum Aero 10-seater commuter in Figure 1.
Sept. 13, 2017, (c) Leeham Co.: Boeing announced today it will boost the production rate of the 787
to 14/mo in 2019, confounding analysts who believe the rate is not warranted.
LNC‘s own analysis agrees. The backlog through Aug. 31 is 700, down 20 airplanes from Dec. 31. The book:bill rate has not exceeded one since 2013.
The rate is not sustainable, LNC believes, beyond 2020.

Our designs have the Zunum Aero 10-seater commuter in Figure 1 as reference.
