Dash-8

Sat Sep 01, 2001 3:41 am

Are the flap settings on the Dash8-100/200 series 5, 10, 15 and 35? Or are they 5, 15 and 35 (no 10deg setting)? Upon looking at pictures of cockpits it appears as if the settings of 5,10,15,35 are displayed on the flap guage on the panel. But on the middle column next to the condition levers and power levers there are only three settings...5,15 and 35. I'm assuming that not all dash-8 models (ie 100/102/103/200/300 etc..) have the same settings. If anyone has some input on this it would be greatly appreciated.

Cheers,
Markus

Markus,

The 10 degree setting is for the Dash 8 300.
Bombardier allows the use of the 300 series indicator in the Dash 8 100's
If an airline operates both 100's and 300's then they only have to keep one type of indicator in stores. I guess it saves money for them, those indicators arn't exactly cheap.  Smile

Does the flap 10 degree setting apply to the -200 series as well since the -200 and the -300 use the same engines? Thanks for the input T-prop
Cheers,

Does anyone know what the usuall takeoff/landing flap settings are for the -300? I would imagine 10 for t/o and 35 for landing....is that correct?

Most Dash-8's do not use full flaps for landing unless its a short field situation. A flap setting of 15degrees is more suitable. Flaps 5 degrees seems to be the norm for takeoff...again 10 or 15 degrees would apply for STOL ops.
Again any help with the -200 series flap settings would be appreciated.
Cheers,
Markus

I recently left an airline where the SOP was flap 35 for landings, regardless of runway length. SOPs don`t have to make sense....................

No, it wasn`t Air BC, but it is now, sort of, since Air Canada merges all 4 of its`regionals. That place is a good example of small, relatively efficient outfits merging into one big monster. Efficiency and common sense just seem to disappear as companies get bigger.
Thank God for small companies, they are a lot more fun to work for.................

I took a position (avionics), with an oil company in North Africa. We have two Twin Otters, and a complete radio shop facility. A bit of a change, but sometimes that`s a good thing.

Hi Dash-8 fans!

Any of you gents work with dash-8's with the rudder isolation system mod installed? This is the add-on mod, not the kind with the right SPU in the tail.

Pete,

Our aircraft have this mod. The only work I've done on this system a while back is reset an iso valve that had activated due to fluid loss.

Probably the reason I haven't done more on this system is because they don't give trouble, not in our operation anyway. Mod 8/1983 on the other hand (#2 SPU relocated) is another story.

T prop.

T prop,

Thanks for the reply. I'm glad to hear the system is performing OK. I took a bit of a risk asking, since I was the team leader for the contractor that designed and certified this rudder iso. system. If the valve activated due to a fluid loss, then it was doing its job!

De Havilland was supposed to incorporate this system in all new -200 and -300's, but after the conversion of all existing a/c, they decided just to stick with the rear SPU concept for new a/c. (We lost a lot of potential busines as a result) I understand they have the overheat problem in the #2 SPU licked now, didn't they end up adding an orifice for cooling flow?

Do you perform the periodic test of the rudder iso. system by pulling on the reservoir level switch knob and seeing if the valve activates? Are you careful not to damage the little transparent plastic covers over the valve indication stems?

I'm sorry I just realized how far off the subject I've gotten. Maybe I'll start a new thread.

Cheers,
Pete

Many is the time I wanted the name of the "?$/*&%/ that designed whatever particular widget I was working on! Pete, you are a brave man! However, I haven't had any problems with that mod. Now, if you could get me the name of the guy that decided aluminium hydraulic lines were a good idea................................. Big grin

Well, it seemed like a good idea at the time!

Now, if you could get me the name of the guy that decided aluminium hydraulic lines were a good idea...

Ha-ha-ha -- I'm sure glad that wasn't me!

I've got to tell you this little story -- When we got the contract from DH for the rudder iso. system, I was briefing some of our management. Our QE manager, who at one time was associated with the FAA or NTSB or some such organization, said ... "Dash-8, huh? Isn't that the one with the aluminum high pressure tubing?"
"Why, what do you know about that?" He just rolled his eyes.

Cheers,
Pete
