CRJ-200 Landing Gear Quest.?

[FmrFreightDog]

I have a better CRJ-200 gear question: Why the hell does it sound like a bomb just went off? Scared the crap out of me the first time I rode on one and still scares me even though I know it is coming.

Makes me jump a little too when I'm in the back, and I fly the damm thing.

I have a theory on that. It's always loud, but I think that it is louder when the airplane is faster. Normally the gear would go down at approximately 185 KIAS, but on occasion it may be lower (when slower speed is required by ATC for example).

Of course this is unprovable, as no one in their right mind would ever ask the pilots how fast they were going when they put the gear down. That's probably why it's so loud to begin with. The Bombardier engineers sitting in the back of the airplane never bothered to ask the pilots how fast they were going when the gear was extended.

It's about the pressure in the hydraulic lines are how fast and hard they slam those releases on the gear doors open.

Asked one of the Bombardier mechanics one time when we picked an aircraft up from factory; he says it's just as loud in the hangar when they do the gear swings on jacks during certification, too.

Never said WHY the pressure is so high and not restricted or something. I'd worry about blowing a line, but evidently they're not, so what do I know.
