However, the altitude system cuts off the hot air, while the landing gear cuts off the cold air. If you forget the lower the gear, the cabin is flooded with cold air, almost enough to make you shiver.
Much like the incident/NEAR TOTAL DISASTER with Air Florida at BNA where some 'dump switch' wasn't working so the PNF popped the CB, however it was 'interlocked' with the automatic spoiler system, so the spoilers popped up on short final and some approach lights were clipped and some structural stuff was bent...the pilots went around (go-arounds are no big deal, you know) and then landed safely.
