It appears that there is a memo going around suggesting that the problems are more involved than just water in the air data sensors.

Specifically, there is a wheel speed sensor, and you should get a warning at about 60 kts if the wheel and air speed data does not match. Additionally, it appears that you can’t turn on the pitot heat too early to dry out the water, because it would warp the skin in that area, which would compromise the plane’s stealth characteristics.
