Is the Ram Air Turbine considered an AC source?
Hello fellow pilots,
This question might be type specific. However I appreciate general philosophy but I'm concerned more about the Embraer E190/170. We have a company policy states that with a single AC source functioning onboard we shall declare emergency. the conflict then rises which is whether to declare emergency over single IDG ,with both otherside and apu gen inop, or not since we still have one more emergency source (RAT). |

Agree with hans. I wouldn't go off knowing that the RAT is my only backup.

Does the RAT not load shed, on the Embraer, at around 130kts? If so I wouldn’t consider it a reliable AC source! |
on the A320 you lose the RAT around 140kts, so there is a chance yours screens will go blank during the approach. |
