Wodrick,
I think everyone here would appreciate an answer to whether or not this relay c/b is pulled routinely when performing the daily check and whether there has ever been any MD SB/AD warning engineers/crews of the danger of leaving this cb pulled.Thank you.
I think what Wodrick was saying is that there is a SEPARATE CB to disable the RAT heater
There is no direct danger in pulling that CB PROVIDED a/c doesn't encounter freezing conditions and need the RAT probe heated in-flight (previously ascertained)
UNLESS, the R2-5 relay might be the source of the fault, when given more time, rather than the pressure of an RTS situation, a not so straightforward troubleshooting exercise would need to be carried out.
Additionally, some reports suggest the strobe was functioning in ground Mode, after Return to Stand... which is also controlled by the R2-5 relay
