Tire smoke gets in your eyes....

It was interesting to watch the arriving aircraft. Most every other type did
not kick up that much smoke. However, ALL of the 737s did. Even a similarly
sized Embraer managed to pull off a nice touchdown with barely a puff of
smoke.

From what I can see, the WJ B737s are not using landing flap settings.

Speaking with 20 years service on B737-200s, we initially used 40deg
of flaps (full) for landing; then when the fuel crunch came, we used
30deg as the normal setting. The WJ 737s do not appear to have that
much flap extended.

The reasoning behind reducing to 30deg was less drag, less fuel
required to overcome the drag, thus less noise.

Using even less flap will require even less power, but the speed will
be higher, and touchdown will be "firmer", producing the tire smoke.

Any WestJetters out there?
