This comes from thread creep on the pass thread.
With adopt and go, the US side is getting most of the changes. I get the theory, but some AA procedures just seem odd to us. I'm figuring that for some of them we just don't understand the logic, so I thought I'd ask.
Does anyone know why we use 10,000' AFL for the cabin chimes? I really don't get this one. It doesn't really correspond to anything. At US we used 10,000' MSL up and 10,000' MSL down, or 10 min prior to landing. Those correspond to steril cockpit, 250 knot speed and in the Airbus the non-magic fingers speed for landing lights. When we leave CLT for the west coast in the Super Slug(321), we hit 10,000' MSL where we are allowed to retract landing lights per the PH(dang, already forgot proper AA term), accelerate to 280 for the SID, then wait until we are nearly out of NC to get the next 750' for the bells. What am I missing?
South America? Left over from when you guys used QFE?
