Semi automatic procedure is feasible if before shut down dry motoring cannot be performed for any reason and APU is not available.
Before going on, set MFD CPL, MCDU CPL & PIL brakers out, RCP to MFD CPL only, all electrical power consuming items set wisely OFF.
Check BATT not bellow 20V and residual ITT between 250° / 280° C.
ENG#1 only, battery start procedure setup (leave all systems checks for after start).
GOV switch: AUTO
ECL: OFF (using beeper trim)
FUEL boost and switch: ON both
ENG switch: IDLE
---wait 5 to 7 seconds, check ITT must decrease---
NG @15% minimum
ECL: IDLE (min) using beeper trim.
example:
A/C long nose, 44Ah & 27Ah batteries installed, EAPS installed, supp. 85 NOT installed, startup @ SL and OAT 50°C, BATT: 20V and residual ITT:280°C: ITT peak on startup could be around 780°C for less than 1 second.
If MFD goes blank: abort procedure or count seconds and push ECL to IDLE anyway, remember the hot start graphic assessment gives large margin to ITT vs time.
