hehe Posted December 19, 2020 Share Posted December 19, 2020 It is in the Aircrew's starting engines checklist of the flight manual. It says something like "normal starting sequence is 3 / 4 / 2 / 1" depending on which flight manual you read Quote Link to comment Share on other sites More sharing options...
hehe Posted December 19, 2020 Share Posted December 19, 2020 Here is a C-130 flight manual for reference. This sequence started on A models because the GTC door had to be manually closed and the engine generators were split between inboard/outboard. So they would start #3 and #4 and then shut down GTC, manually close the door and then start left wing. Some pubs mention starting engines in a different sequence than 3/4/2/1 to spread the wear and tear on engine starters. The first engine started off of GTC/APU Bleed air will wear faster than the others with engine bleed air because of the higher flow/pressure from the engines. Generally speaking, if you 100% always start #3 first, data/trends say that you will replace the #3 engine starter before the other engines. 1 Quote Link to comment Share on other sites More sharing options...
