Widerøe Dash 8 Q400 Startup and landing at Stord Airport, Oct. 2020. 

Me to I love blades pitch

The sound it makes is amazing

Yeah they become huge

Buyhh

I can tell because that’s your logo !😅

Stupid, that's how....IMO!

I dont know….

crazy

I think they thought it was the download button…

its also partly because of the blade pitch

As the propellers are unfeathered into flying position there will be less drag and the blades can cut through air easily so they will turn faster than while being feathered.

@@deception1744 it’s completely because of blade pitch 😂

Om yg

What does the wiper position has to do with noise reduction?

@@Altenholz the wipers are horizontal in their off position, which means you get to hear every single knot of wind pass over them. When you flip them up vertically they are streamlined with the wind and significantly quieter.

@@fhslax Well, damn my a*@!s in hell.

What simulator do you have?

She's kind of hard to land, even the real Q400 pilots say this. You have to treat her gently :)

Same direction, from the cameras view anti clockwise, or from the pilots ‘view’ clockwise.

One of the fastest turboprops in the world. Can cruise up to 360 knots (667 km p/h).

They feather the prop

This is purely visual effect due to camera filming 30 (or maybe 60, or some other figure) frames per second.

Yeah, I hate digital cameras for props or rotorcraft.

The starters on this engine are electric, not high pressure air. This start was done with electrical ground power (GPU). Q400 have an auxiliary power unit (APU) in the tail for electricity and air conditioning without main engines running although they have a reputation for unreliability so use is avoided where possible. A battery start is possible but as a last resort only as it's very draining on the batteries.

Almost all props in twin engines turn the same direction it's very rare to have opposing rotating props. It costs too much for maintenance when the engines don't all run in the same direction

Vhhhhhhj.... Jjkkknbbh? Kutu tapi 0y7 pop

That’s called blade pitch, they normally do this with the 400’s and 300’s. they go from feathered config (which is when the blades look really skinny) to flight config (which is when the blades look really thick) you would normally have them feathered during engine startups to idle and if you were to have the blades feathered during low speeds it could possibly lead to a mid air stall.

Q400 is quicker

They are not. Just prior take-off, a cockpit switch controlling the spoilers is set to the "Flight" position, and with the power at idle the spoilers extend. As take-off power is applied, the spoilers retracts and stay retracted for flight (note they are also used in flight for roll control). If the take off is aborted for some reason the engines are brought back to idle and the spoilers automatically extend and help slowing down the aircraft. Same thing happens on landing, with power at idle and aircraft on ground, the spoilers automatically extend. Once the aircraft has slowed down, the cockpit switch is set to "Taxi", which retracts the spoilers on the ground for taxi in, until the next take-off. This is a simplified explanation, the system is a bit more complex than this, with safety features that prevents inadvertent spoiler deployment in flight, etc.

@@nonamesthesame e Q

The Q400's are as big as a DC-9-14/15 series as well, just not quite as fast or with the same range. They're quite efficient, though, combined with jet-like speeds.

Nope. The An-132 and Q400 are totally different. However, they do share the same engine and propeller.

@CREEP MATT GAETZ No, this is the De Havilland Canada (or Bombardier) DHC-8 Q400. The ATR is another turboprop that just serves a similar role to the Q400.

I think you may be mixing up feathered vs unfeathered. They start with the props feathered (parallel to the airflow) which reduces noise and fuel consumption, and then unfeather them. On landing they disc the props (make them perpendicular to the airflow), as you said, to slow down. Reverse thrust is rarely used (at least on the q400) just because discing is effective on most runways. On shutdown they feather the props again for the reasons mentioned earlier, and to let the engines cool off a bit and stabilize before shutting down. Hope this info is useful!

@@sebsaviationyyc Happy to corrected, thanks. I learnt something new.
