Significant Yaw on Landing

Post by pelmet »

Seems odd but if one already has a back issue, I can see it being aggravated. An AC A220 landing I experienced a couple of months ago created a bit of pain for me, yet I am sure the data would not have shown anything particularly unusual....

C-FIVM, a Boeing 777-300 operated by Air Canada, was conducting flight ACA415 from Montreal
Trudeau International Airport (CYUL), QC, to Toronto Pearson International Airport (CYYZ), ON.
The aircraft was on approach for runway 05 with a strong crosswind (METAR reported wind:
33016G25); during the landing flare the Captain took control to ensure landing on the centreline,
which required some relatively brisk control movements. Initially, three passengers who were
seated towards the rear of the aircraft reported that they had been injured during the landing due to
the aircraft yawing abruptly. The flight crew arranged to have EMS meet the aircraft at the gate. All
three passengers who had reported an injury after the landing declined to be assessed by the
waiting EMS personnel and walked away from the gate. The flight data was reviewed by engineers
at the TSB laboratory: there was no indication of unusual yaw rates or lateral acceleration during
the landing.

Pearson should really build a runway facing that way. I’m pretty sure they have the land for it.

After they build one, likely could consider building a second so they could get two runways into wind.

In all seriousness, in the last 6 or so years I've not seen YYZ use all 3 24R/L (06L/R) and 23 (05) other than now where they are using the inside runway as an expensive taxiway.

How does arrival and departure rates change when using 33/15s if it is essentially the same (albeit closer) than when running two runway ops on the East/west runways.

Why? 16G25 crosswind is too much now for airline pilots?

Maybe all those FTUs with 15 kts crosswind limits were on to something after all!

As an AvCanada discussion grows longer:
-the probability of 'entitlement' being mentioned, approaches 1
-one will be accused of using bad airmanship

Apparently. More than that, if an into-wind runway exists do we not owe to our passengers the comfort of using it, especially if it’s gusting?

I can’t believe this isn’t a joke of a thread, right? Isn’t it? :roll:

What's the proper crosswind technique for a aircraft like the 777?

Boeing gives one options for their big jets. Wing down like a Cessna, crab then kick straight, or crab to landing but be careful about that on dry runways.

Spent a number of operational years in YYT( when the gales of November come slashing), good crab on, keep it lined up, rudder to straighten the fucker on the flair out and lower the windward wing. Worked for me during those years and didn't bend either of the airplanes I had the pleasure to drive. Now those 100 &1/4 approaches, well that's another topic.

So when you kick it straight what happens to the rearmost passengers in a 200 ft long aircraft?

From the first post:-
The flight data was reviewed by engineers at the TSB laboratory: there was no indication of unusual yaw rates or lateral acceleration during
the landing.
Here's how not to do it:-

Always fly a stable approach - it's the only stability you'll find in this business
