Freight sounds ?
 

Ok, I have a silly question.


In turbulence or bumpy air in a large freighter do you ever hear the freight pallets and or containers 'straining' against their locks.


I realise you probably wouldn't in the cockpit with the ambient noise but what if you are in the passenger area of the upper deck on the 747 for example or just behind the cockpit on other Aircraft .



Rather like the sounds containers make on a ship make in a heavy sea ?

No, we don't hear the pallets straining. We do hear the cans popping we we haul engine cans and do feel and hear the horses stomping on horse charters.

Those cans really are loud. I was shocked the first time I started hearing them. Empty drums make lots of noise too.

Pallets are nice and silent.

In a passenger aircraft, you may sometimes hear the under- floor containers (LD's) clunking with forward/aft movement, ie; power changes, pitch changes etc.usually as a result of not having been secured correctly in the floor locks.
The A300 was particularly prone to this in the Fwd belly hold, don't know why but it did make new crews on the type prick their ears up!

Hey, did you hear that?
 

My favorites are the boom hissssssss and whoooosh.:uhoh::uhoh:

Having cargo door seals blow out is a blast! The fun is offset by the stink that follows. Oh yeah, I did find out that the FO didn't pack a spare pair of tighty whities!

The poster above is dead on about the engine containers and empty sealed barrels.

If you hear other booms or pops you may want to land at the nearest suitable airport. Shifting loads have and do kill. Miami International still has some scars from a DC-8 crashing after a load shift.

Thanks for the reply's, in the cockpit of passenger Aircraft I have heard lots of noise from pallets and containers being loaded but certainly not during flight.



With the state of relations between the Flight Deck and Cabin Crew these days I often think that freight sounds more appealing :eek:
