I wonder what official position (if any), the FAA is taking regarding what the intent of the "30 minute" wording in their Regulation is ?
Is the "extremely remote" design calculation still valid based on current total TIS of the aircraft ?
Is there an ELS "bolt-on" fix possible ? Don't see why the FAA couldn't issue a new Amendment to FAR29 to push the whole thing forward - commercially it could be consdered an "upgrade" and given the current climate wouldn't a "flow-through" cost be acceptable to all, in the interest of pushing the safety envelope forward ?
