An electric power generation controller for use in an aircraft to control an electric power generating apparatus including a manual transmission which changes speed of rotational power of an aircraft engine, transmits the rotational power to an electric power generator, and includes a plurality of gear stages. The electric power generation controller includes: a rotational frequency receiving section configured to receive an input rotational frequency or an output rotational frequency of the manual transmission as a monitoring rotational frequency; and a manual transmission control section configured to, when the monitoring rotational frequency exceeds a first threshold, output a shift-down signal to perform shift-down from an upper stage to a lower stage, and when the monitoring rotational frequency falls below a second threshold, output a shift-up signal to perform shift-up from the lower stage to the upper stage, the first threshold being set to a value larger than the second threshold.

Electric power generation controller for use in aircraft

An electric power generating apparatus for use in an aircraft is an electric power generating apparatus connected through an emergency cut-off device to a gear box such that the gear box can transmit power to the electric power generating apparatus, the gear box being configured to decrease speed of rotational power of an aircraft engine. The electric power generating apparatus includes: a manual transmission configured to change the speed of the rotational power transmitted from the emergency cut-off device and including a plurality of gear stages; and an electric power generator to which the rotational power which has been changed in speed by the manual transmission is transmitted.
