Those Crazy Sweedish Dash Drivers! (gear collapse)

As soon as you ask one within the domain of the DHC-8 systems, of course I will.

Do you have a hydraulic pump which can be power though an inverter, from a battery, on a standby system or mode?

I.E.:
A 28vdc to a bus through an ac inverter to one or more pumps which can power one or more hyd systems in the aircraft.

This is the most fun I have had in a long time!!!

Give'em Hell Russian!!!

Quit eggin' her on, B-Dub! This is kinda fun, though.

Hey Russian!

Now go back to telling us how to fly a B1900 you've bought a job on, and shut the he|| up on telling us how to fly Q400s/DHC8s when you know nothing about the airplane.

There isn't enough bourbon in Kentucky to get me to her level of arrogant BS-ery, to the point where I'd be correcting an old ASA pilot on the Bro! I'd be ashamed of myself.

Listen to what you are being told, Russian. The Dash uses 115v variable frequency (3 phase) AC to run the standby hydraulic pumps. This power comes from the AC generators which generates electricity when the prop is turning (it is on the prop reduction gearbox). The inverter produces 115v FIXED frequency AC to power some of the avionics. It cannot power the standby hyd pumps. Different bus, different power. No worky worky.

The main hyd pumps are also on the prop reduction gearbox. You can close a gear door if maintenance left one open on a dash by walking up to the right prop and spinning it in the direction of travel for about 5 turns.

So now we have demonstrated to you that with no props spinning on a dash, you get no main hyd pumps, no AC generator, and therefore, no standby hyd pumps. The rudder has a standby pressure unit, which was designed after the N819PH accident described above, so you would have a rudder, but no spoilers, no nosewheel steering, emergency brakes only (with a handle you have never used before) NO ANTISKID, and probably something else I can't remember from 5 years ago.

You didn't have all the facts when you made your "shut 'em both down" comment. Now you have a couple more facts.

For literally the FOURTH time: NO.

Did she PFT? I always gave her the benefit of doubt on that one.

Lunch, I'll be back.

Might I suggest "Crow?"

Horizon must be cancelling flights to tell the crews to shut off both the engines if they have a red light on the gear indication. LOL.

Horizon cancels 113 flights

By BRAD WONG
P-I REPORTER
Thousands of Horizon Air customers will have to rebook or find new flights immediately, following Wednesday's announcement that 19 turboprop aircraft will be pulled from service for inspections.
The precautionary inspections will affect at least 113 flights Wednesday, said Laurie Hohisel, a Horizon spokeswoman. Passengers should be prepared for cancellations throughout the week.
The Seattle-based carrier is encouraging customers to check its Web site, www.horizonair.com, or call 800-547-9308 for assistance. The carrier also might book passengers on other airlines.
The inspections of the Canadian-made Bombardier Aerospace Q400 airplane follow two cases in Europe on Sunday in which SAS-affiliated Q400s had landing gear failures, Hohisel said.
Affected Horizon flights include ones from Seattle to Spokane, Portland, Reno and Bellingham.
Horizon, which is owned by Alaska Air, will use aircraft from Alaska Airlines for 13 flights, said Caroline Boren, an Alaska spokeswoman.
Hohisel does not believe those flights will be able to replace all of the cancellations. "But it will help," she said.
The Horizon inspections are scheduled to begin as soon as possible and will be conducted by company mechanics.
But the flight delays could affect more than 8,300 passengers. Each Q400 holds between 74 to 76 passengers.
The aircraft manufacturer asked Horizon to look at Q400s that had over 10,000 cycles, which means a departure and landing. Horizon has operated those planes since 2001.
But the announcement will not affect 14 Q400s.
Each day, the carrier operates about 480 flights. Of that number, about 240 are flown on Q400 aircraft.
