250 KIAS SPEED RESTRICTION

A Canadair RJ-200 pilot reported a 250 KIAS speed restriction due to
structural reasons.

Can anyone provide more detailed info on the RJ-200 problem???

In the old Boeings, we had a similiar restriction if the windshield
heat was inop. Bird proofing.

Huh? What does windshield heat have to do with birds?

The colder the windshield is, the more brittle it is.

Drink is the curse of the land. It makes you quarrel with your neighbor.
It makes you shoot at your landlord. And it makes you miss him.

The colder the windshield is, the more brittle it is.

The windshield or the pilots?

The analogy used when I was taught this was to consider the nature of
toffee; warm toffee bends and will rarely shatter if dropped, toffee from
the fridge shatters with minimal impact. Same deal with the glass and
laminates in the windshield.

Windshield heat probably has something to do with windshield strength.

Supposedly, a bird striking a warm windshield will bounce off rather than
breaking though. I'm sceptical of that myself, but I expect that the bird
doesn't care either way.

Sounds fishy. If there were a structural problem that required slower
speeds, I would think the FAA would ground the fleet. And, who would
fly them anyway with such a limitation?
