What! In excess of walking speed you mean? Okay, I'm being sarcastic, but GS
high?
The FCTM says sideslip only landings should not be attempted in crosswinds above 18kts with Flap 30 due to lack of control authority and pod strike risks.
And what does that mean? One has no choice about the TOTAL energy put into countering a crosswind but on the early jet transport aircraft just a tad of side really does effect a lot of stabilisation.
