I have read that the 737 has a higher takeoff weight than landing
weight -- ie you could takeoff heavier than you could land.

Yeah, they all do.


Is that so? Is it just a recommendation? If this were to happen in a
737 and you need to land right away, is the weight issue blown off?

Yes, you just log it and there is an inspection. Depends on the type, but
it could take three minutes or hours, depending.

(which leads me to suspect that it can be blown off, ie, it is a
recommendation). If not, why would you ever take off heavier than you
could successfully land?


To make money hauling ****, of course!

There are two reasons for the lower landing weight. one is structural. The
flaps are out further and the strain on the airframe is larger during
approach. Two, if you bang it onto the runway, the stresses from the higher
wieghts could damage the thing and the other reason can be peformance. the
airplane won't climb as readily with approach flap out. The performance one
is not usually an issue, though. Mostly only if you'r ehot and high or
there are obstacles in the go around.

We can dump fuel n a lot of airplanes for this very reason. The 737 does
not have this facility, though. Mostly it's a long haul thing.
