Tire smoke gets in your eyes....

?....and farmer's burning stubble too. Sigh. Tons of haze today.

Wow, can smell it from here!

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.

A good source of income for those who make the tyres. Tut! How cynical.

Maybe because there are only two wheels per truck instead of four.

I don't have any stock in them..... :-)

I know some aircraft have wheels that help the airstream spin the tires to
ease the contact somewhat. I wonder if this is standard on all aircraft or
if it came into use fairly recently?

I think that's been around for some years.

I can still recall, as a paratrooper in the 60s, standing in the door of
a Blackburn Beverley waiting for the green light to come on so that I
could depart and watching the main undercarriage wheels turning in the
slipstream. I doubt, though, that that was intentional in order to
reduce tyre wear.

Hmmm.... I'm not so sure this is the answer. Everything else coming in was
of the CRJ / Embraer / Regional Jet variety and all of those seem to have
two wheels just like a 737. Perhaps it is a landing weight and speed
dependant issue more so than anything else. Then again, pilot skill has
something to do with it too. One particularly smoky landing gave me two sets
of puffs as the aircraft bounced down the runway on touchdown.

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?

AHA! I knew it must be something related to either the type or the way it
was being operated. Interesting. Someone told me that WestJet will even
request the most direct approach to save fuel and even use a less optimal
runway if the approach is more direct and will result in a fuel saving.

I tell ya - for folks that brought us the Fury/Hart, Spitfire, Hunter,
Comet and 'alf a Concorde, you Brits could sure hit the urgly button
once in a while!

(Yeah - I know Boeing crapped out the X-32...)

Ain't called "Boings" fer nothing...

I've seen Seattle-based Alaska Airlines - experts in greasing 737s
into short fields in zero visibility with 40 knot sidewinds - nearly
break the wings off in calm sunny weather.
