B738 vs A332 hold temperature
Hi All,
Longtime listener, sometime poster.. Can anyone tell me what differences (if any) there are in the way the hold is heated and cooled between a) the forward hold of the B738 and b) the aft bulk compartment of the A332. These being the two holds that AVIs are usually accommodated in on these two aircraft types. I am a veterinarian (and onetime PPL) and I see quite a few pets who travel by air so I'm just trying to extend my professional knowledge of what the climatic conditions are in the hold and the B738 and A332 are the main two types operated by our local airlines. As I understand it the holds are heated/cooled by 'second hand' air from the passenger cabin through use of various fans and valves but I haven't got further than that...
Thanks.
