Start with hot avionics, cold engines

[Weta43]

If, as it says in the manual:

"When a helicopter is starting from a “cold” state at the beginning of a mission, it is already connected to external power supply by default. Therefore, there is no need to explicitly request to connect to it."

Then if there's a reasonable possibility that an aircraft will have to 'scramble' in a hurry, shouldn't it - wouldn't it - be possible for systems that take a long time to initialise - like the full INU alignment - to have already had this done & be sitting hot running off ground power while the engines are cold ?

There already are such options like short INS or stored heading alignment in MiG-29, F-14 and F-15E afair.
