Anyone know the approximate Vref for the CRJ? I downloaded one into MS FS, and I was shooting the 18L ILS at CVG. I came in too hot, and, well, let's just say I floated a bit. So to anyone who flies one, or just anyone who happens to know, I would love you to impart some of your knowledge.

Thanks,
Mike

Western727,
why not do a simple flight test yourself? Set the aircraft up in the desired landing configuration, fly straight and level then slow down until it stalls. Take that speed and multiply by 1.3. That would be your Vref for the airplane model you downloaded.

Have fun  Smile/happy/getting dizzy.

The approach should be flown at VREF+10=VPROG

I was told they do around 150 kts on final approach in the CRJ. So I guess the Vref is around 140 kts. I'm not sure if this was with a reduced flap setting. Obviously the Vref varies with weight and configuration etc., but they do have high ref speeds even with full flaps.

I thought it would be an interesting topic for discussion. Isn't that what this forum is all about?

Absolutely ! If you want I can ask a CRJ pilot -the next time I see him- about a specific Vref; let's say max landing mass, full flaps, ISA sea level day.

Western727, the ref speeds for the CRJ are as follows:

34000 lbs. vref=121
At 47k (max landing weight) it is 143kts.

A typical ref speed would be 140kts at 45,000lbs.

I hope this helps. Happy flying!

Western727,

I think that MD11nut gave you a wonderful answer, why did you have to knock him for it?

He gave you an insight into how the Vref was derived, he had turned you into a testpilot, guess what you blew it!

I don't recall knocking anyone for anything. I was merely explaining why I made that post. The term 'knocking' implies disrespect, of which there was none. Besides, I'd like the input of those who are more knowledgeable than myself, which this forum provides.
