The weight for carry on bags is included in the passenger weight. Each checked bag adds weight. By maximizing the number of bags that fit in the cabin they reduce the number of gate checks which reduces the weight used in the weight and balance calculations.
I have no idea how turbulence would have factored into this unless turbulence enroute was forcing a lower cruise altitude which would require more fuel.

In the belly it counts as a bag. In the cabin it's part of the passenger's assumed weight. It is an accounting trick.

How wide are the margins on weight and balance? At what point does a substantial deviation between actual and assumed average passenger weight cause trouble?

Personally, I have no idea of the exact aircraft loading margins but I'm sure they're pretty conservative considering since the figures used to calculate weight/balance are mostly averages and or estimates.

[QUOTE=drewguy;27828187]Anything from 19-seats and up will have a tiller but they still have limited nosewheel steering through the rudder pedals. You sue the tiller at taxi speeds and the rudder for nosewheel steering during takeoff and landing roll.

Assumed for bulk bags, they may weigh containerized bags on the larger aircraft like they do for cargo containers/pallets, I'm not sure.
Legally you can't be over weight or out of balance.
As you can see on this typical, if dated, weight and balance envelope, the allowable CG range at takeoff for a 737-500 is about 16 inches.

Our flight was cleared for landing at LHR 20 seconds before touchdown, I heard on ch9. Is that normal for busy airports or is there a different standard in that country? I feel like when I've listed to EWR ATC the planes are often cleared with at least one inbound aircraft in the air in front of them but maybe I am mistaken.

The United States is one of the few places where ATC can use anticipated separation in clearing an an aircraft to land. Which means that we can have many aircraft cleared to land on the same runway at the same time if in our (controllers) judgement the preceding aircraft will be clear of the runway by the time the following aircraft touches down.

Are paper charts and plates still carried or is everything electronic?
