Method and system for starting an engine

- 13 Aug 2020

TL;DR: In this article, the engine start request is received on the second channel while the first channel is inactive and it is determined which one of the first channels and second channel was used to conduct a last successful engine start.

Abstract: Methods and systems for starting an aircraft propulsion engine are described herein. Operation of the engine is controlled by an engine controller having a first channel and a second channel. An engine start request is received on the second channel while the first channel is inactive. It is determined which one of the first channel and the second channel was used to conduct a last successful engine start. Responsive to determining that the last successful engine start was conducted on the second channel, a predetermined time period is waited to elapse and for the first channel to reinitialize before commanding, via the first channel, an engine start based on the engine start request.
