How fast is the Dash 8 - Q400?
 

Anyone care to satisfy this old Bonanza pilot's curiosity?

What is the TAS in cruise of a Q400?
How does this compare with the "non-Q400"?

What did they do to get the Q400 to GO?

My interest was triggered by the fact that, over a short leg (<200 nm) the Bo is generally not too far behind older Dash 8's, but I recently "raced" one of the new ones from Mackay to Rocky. I took off from YBMK behind one with only the length of the runway between us, but it was taxying YBRK for departure before I had landed.

Seems very quick!

Are the QL Dash 8s breeding? There were at least 8 of them on the ground at YBBN today !!!!

FTDC:cool:

bit faster then the Q300 bit slower then the B737, bigger engines make it go faster, and the red tail makes it go a little faster - note to designers if they painted it all red it would go even faster.

put a pair of Roles Royce engines on those wings and it would go even faster.


I'll pull out some documentation when i get home and post for you

TAS of 360 is fairly common. Max cruise is around there too. PW150A engines are actually based on PW's 4000 series turbofans apparently. 3750 odd KW of power out of each of the buggers! Roughly twice as powerful as older props, and uses significantly less fuel. Now who said props are for boats...:E

Just look at QF's block times for YSSY-YSCB flights in the Q400 compared to the B734.

Impressive :D

CMN :ok:

Bout 350/65 Kts as reported is correct! The bonks have the same core as the J-Model Hercs operated by the RAAF. Qlink were looking at replacing the leading and trailing edge de-ice boots and utilising bleed air to heat the wings in icing conditions if required, thus extending the speed to an estimated 385kts! Yep this is one fantastic machine,:ok: however will Mr Joe Public continue to commute in one when VB start going head to head against this a/c (with there Ejets) one has to wonder?:confused: :confused: :confused:

Is it just me or has anyone else found them horrendously noisey inside? I liked the inside fit out of the new 400s, but on a CBR SYD - sector the noise was almost unbearable. Couldnt wait to get off.


Never found the noise as bad (memorable) on earlier models.

I too have heard that the 400 is a bit of a disappointment in the noise department, especially considering it being a modern plane with those fancy 6 bladed props. I find the earlier models to be one of the quietest turboprops around on the inside, at least in cruise, so would have thought all the advancements in noise suppression would have found its way onto the Q400....apparently not though:confused: Will have to go for a burn on one and see for myself:8

Sounds like dey are like rooly, rooly fast!:E

Q for Quiet?
 

Did Qlink not get all the electronic gear that quietens them down? Rode on an old 100 series the other day and boy are they loud!

Bloody slow really.

(Props are for boats)
:p

Yeh, but not over short setors Mr Bloggs....:ok:

73, 71, 320 = 30% quicker...............anyone who thinks 30% is a " bit " , I have a bit of land for sale :E

Even on our shortest sector ( 270nm ) we would be on the ground when the " boat " arrived in the circuit ( notwithstanding shonky ATC ala CB-SY )

Never mind speed.. the Dash8-400 goes tech quicker than any other aircraft on this blue planet! :eek:

Trailing edge deice boots?

What are you smoking?

How much do you have to slow down when you start hitting a few bumps down there at 20k?

Hahaha... ITS ON!


If thats what they really Tas at (360) then im pretty sure thats quicker then the C130J... Pass-A-Frozo should be able to confirm!

Funnily enough more crying tends to be heard from above FL300, than below...http://www.augk18.dsl.pipex.com/Smileys/stirthepot.gif

If I am not mistaken the 400 series is a Medium wake turb above 25,000kg - unlike the 300 series and below.

If this is the case I hope that you requested a wake turb waiver from ATC as this sounds like a break down of departure wake turb. Light behind Medium you gotta have 2 mins or 5 nm :eek:

Err, I think medium category starts a little lower than 25,000 kg's, say 7000 Kg's (with thanks to flightfocus)...:O

I am not a nerd!:ok:
