My question is on the video. This looks like that plane had some black spots like a fire had occurred. Also what is this like the 3 or 4th 777 fire alarm diversion in the last few weeks??
There haven't been anymore bird strikes over the past few weeks than normal...3 or 4 fire diversions in a triple 7 in the last few weeks is not normal!
I've said it before, but I'll say it again: cameras would *not* aid fire detection on airplanes. If you can visibly see a fire within the hold, you've already lost. The detectors are as often inside the wall, inside the wiring, where no human can see (and where you'd need dozens and dozens of cameras to cover every such spot on the plane). The point of these detectors is to detect something wrong before open and self sustaining flame occurs (i.e. smoldering from shorted wires).
(Of course the major exceptions is fires within the cargo itself, but as I said, that's only a fraction of the cases the fire sensors are designed to handle)
Actually cameras would aid the pilots more than just detectors...the detectors go off indicating smoke in the hold, the camera help determine the actual "sighting" of the smoke intensity. And with today's small cameras and tech, you wouldn't need dozens and dozens, and they would not be very big.
I see a bit of smoke or a lot of smoke...that plus are there flames?..best line of defense in a fire is to knock it down before it can get up. Sorry but I did not agree with Dubslow's " If you can visibly see a fire within the hold, you've already lost." No you haven't.
yes but a lot of cases turn out that something triggered the alarm, and they divert and find out it isn't a fire... a camera would tell you whether or not there really is a fire..
They put cameras in the A380 so the pilots could have a view of what was going on around them. Night vision camera's are now pretty cheap. No reason for not doing this.
