CRJ 700 Crosswind Limits

[transducer]

Can anyone help out, with references, the crosswind limits (demonstrated or otherwise) on the CRJ 700. The only limit I have found is in the FCOM 2 Supplementary Procedures about wet and contaminated runways saying that on a wet runway 27 knots is max and 15 for a contaminated (snow or ice covered). There is no other reference to limits, other than the rolling vs. static, in any of the official documentation that I have managed to track down. Maybe I'm missing something?!

CRJ 700 Airplane Flight Manual Chapter 6 (Performance) page 06-01-30 item 5D

Demonstrated Cross-wind (Take-off and Landing)
The maximum demonstrated cross-wind component for take-off (at 33 feet [10 metres] tower height) is 28 knots and is not considered limiting.
The maximum demonstrated cross-wind component for landing (at 33 feet [10 metres] tower height) is 30 knots and is not considered limiting.

As it says, "not considered limiting", so nothing is in Chapter 2, Limitations.

At my airline, the crosswind limitations for the CR7 are as follows:

For takeoff:

28kts if braking action is good or better;
15kts if braking action is fair;
10kts if braking action is poor.

For landing:

30kts
15kts
10kts with the same braking action stipulations.

These are steady-states speeds, not gusts, so if I'm landing on Runway 36 and the wind is reporting 270/29G45, I'm still legal.

Dear flyboyike (http://www.pprune.org/members/135146-flyboyike),

Does your airline state that these are steady winds or do you assume this? Most advisory material from manufactures on crosswind versus braking action assumes steady wind without gusts.

Legal doesn't always mean that you are safe.....

[flyboyike]

My airline specifically and explicitly states that these are steady-state limitations. I agree with you on your legality vs safety point, I was only reporting what our book says. Word for word.

speaking of which, they have a nice iPhone app that figures out crosswind/tailwind/headwind components including the gusts and it's free.
