There are several reasons why a manual start may be required including low pneumatic pressure. The main difference between a manual and an automatic start is that the pilot controls the time at which fuel and ignition are supplied to the engine. The FADEC only provides passive monitoring of the engine during the start sequence. This means that responsibility for preventing an over limit start remains with the pilot. Note: Manual starts are completed using the procedure detailed in FCOM 3- procedures and techniques MENU POWER PLANT (IAE) Manual Start 3/31 The FADEC controls: - the closure of the start valve at 43 % N2 - and ignition cut off on the ground. MENU POWER PLANT (IAE) Manual Start 4/31 The configuration is the same. On the E/WD, all indications related to the engines are displayed in amber as long as the FADECs are not powered.
