CVR CB Posn During Towing

Fri Jan 14, 2005 4:00 pm

Is it Mandatory for Activating the CVR CB during a Mx towing operation from one bay to another parking bay adjacent.
In other words,Everytime the Aircraft is moved [Towed/Taxied] the CVR CB should be in.
Anyone.

Your GMM (operator procedure manual) will dictate towing procedure, including whether or not the CVR C/B needs to be pulled.

Yup, its all operator specific. I've worked for airlines that required the CB, for both CVR and FDR, pulled and I've worked for operators that insist (checklist item) that they are in.

On reflection, in the past ten years or so, as the industry has moved from tape based to digital based recorders, the tendency to pull the CB has gone away. My guess is that since we (maintenance) are not eating into the life of the CVR or FDR recording medium, our operators will insist that the recorders are operative in case of a problem, so the "tapes" can be reviewed.

in the JAA regulations it states that the CVR only needs to be on when the a/c is operating under it's own power...however operators may impose stricter regulations.
The only time there is too much fuel onboard, is when you're on fire!
