Hi Max :
Our POH shows in addition from what you mentioned to turn ignition ON if the runway is covered with standing water , or if heavy rain or severe turbulence is expected during approach or go-around.
The severe turbulence procedure in the supplementary techniques does not include ignition to ON .
So lets say you took off expecting turbulence , ignition selected ON in order to keep it on after flap retraction I guess , and maybe as a back up for the auto selection when the flaps where dawn , or ???
Now when do they expect us to turn it off and why ?
As I said , the severe turbulence procedure does not call to have it on .
It's been ignition ON when in rain for my past 30 years on other aircrafts , this FCOM's talks about it only related to departures and arrivals . Why ?
Max ? Anyone ?
