Q400 operators
Hello fellow Aviators;
I am looking for operational information on the Q400.
If you are or have operated or dispatched a Q400 recently I would very much like to pump you for real life info.
In particular I'd like to establish performance data but, I am reluctant to use Manufacturers sales pitch info.
I'd like to know real TAS, alt. capability, fuel burn etc. I anyone has access to a simplified Flight planning graph or software I would really appreciate it
I'm operating in a tropical climate, shortest sector about 100nm, longest 800nm with most falling around 3 - 600nm.
Compensation is offered in Beer, Rum, Jerk Chicken or Marinated Conch currency
Thanks

The Q400 performes quite well, not behind the book figures normally.
Only problem is it stinks! And fails every once in a while (read: one per week).
My current outfit is desperately trying to get rid of them, would rather take ATR!

We have a god dispatch rate (fantastic technicians), at MTOM FL250 is possible with about 330TAS/M.5.
There's no harm trusting in BBD's figures about the machine.

Dash8Driver is correct.
Just a little addition: of course, performance is a bit dependent on temperature. While I have never had to reject the intention to climb to FL250 yet, high OATs tend to make the last 2-3000ft a chore.
With regards to fuel consumption: at maximum cruise rating and FL250, expect around 330-360kTAS (weight and OAT dependent) and a fuel flow of 2500lbs/h. In case of no performance limits on departure or landing, MZFM allows for 6930lbs of takeoff fuel, so assuming IFR reserves of 1800lbs, a distance of 600NAM should be well feasible; anything beyond that would require lessening the passenger load. Mind You, the MZFM of 57.000lbs is rather generously calculated and in my experience only limiting in case of a full pax load, much luggage plus some cargo - a full pax cabin without cargo will show a ZFM of around 55 to 56.000lbs typically in our operation, so the figures I estimated above are highly conservative. In case You like to calculate for Yourself, a ballpark DOM figure would be at 42.000lbs.
