Landing the Twin Otter

Recommended Posts

Im still in the early learning stage of flying the twin otter and im having trouble landing it. From videos ive seen of the real thing, they seem to approach fairly flat, almost nose down and there looks to be very little flare on touchdown. Im touching down around 70 as per the figures with 20 flaps but in order to get a fairly smooth touchdown im having to pull back a fair way leading to a very nose high flare which looks very unrealistic.

What should the trim be set at ideally for say a 11000lb landing, and what percentage of power? Too little power and it drops onto the runway, too much and it just floats above.

Any advice would be appreciated, and also to the other couple of queries i posted yesterday.

Many thanks in advance, Regards

Andy

Please relax your attitude, if you want people to help you.

This forum is primarily for support issues for the product, and you are now going into details about flying procedures. Not all fellow Twin Otter users follow this forum on a daily basis.

Did you already read all the provided manuals?

There isnt actually a 'how to fly the aircraft' manual. Just the systems, checklist, and data pdf manuals, which ive read.

It could do with a POH really

I think you can land with a higher vref, like 90 or 100 kts. Plane stops quickly when you feather the props. I am also new to the Twotter.

Unintentionally teach anything, but only help,
at sea level, average weight, reduce the torque to about 15 'hg, let the speed down to 80 kt with 30 degrees of flaps and 500 ft / min + or - 2 degrees down. Try to keep the 80kt and 500 ft / min slightly adjusting the throttles (gently).
Practice this to about 3000 ft msl: imagine a runway in front of you and try to keep this ramp.
For landing, just enter the flare and wait for the touch!
Usually do these exercises will help to get used to the controls and aircraft settings.
80 kt is a good speed for landing. 70 kt is very tight, but can be used ... if there are good understanding of powerplant!
Cheers,

Sinesio, many many thanks, ive tried your figures are they were spot on, pretty nice landing with nowhere near as much flare. Props full forward, 15 hg torque was around 60% on the power gauge, 80 mph at the threshold.

So the figures in the data tables seem to be incorrect then? Especially the take off figures of approx 65 at VR, and 75 V2 with flaps 10. I cant get the thing off the ground at less than 75 and thats with 100% elevator trim!

The landing figures dont quote anywhere near 80 kts for landing even with flaps 40 so their figures are a complete mystery to me.

Do you suggest flaps 30 landing even on long runways? Or would you happen to know the figures for a flap 2 landing? Presumably just slightly less on the throttles?

Its a very delicate balancing act between the props and throttles with this aircraft it seems, a pretty steep learning curve for me but i love it so will master it in the end.

Regards

Andy

1)As already said this is a technical support forum not a general caucus forum. For that try AVSIm.. You will find HUGE input on general flying tips and have dedicated forums where this is being discussed in great deal normally with a lot of real pilots frequenting these forums.

2)The figures are indeed correct for a person knowing what he is suppose to be doing.

3)The twin otter is really not a plane to start of your FSX training and buying such an intricate plane surely you should know that you will need to first understand the basics, before jumping into such a plane and expect it to work 100% to your liking.

4)There are just too many variables to have a specific speed as a golden rule for every takeof/landing. Weight/weather - wind, atmospheric pressure, height above sea level/runway type/aircraft configuration etc etc etc all play it part in the deciding factor what the takeoff/landing speed is going to be.

Maybe stop blaming and start studying the aircraft MIGHT put you in a better position to throws around comments of wrong figures. These were taken direct from official documents and the plane is pretty spot on developed within the limitations of FSX to replicate the real one. I must say this is the best one of FSX turbine props (that was developed within FSX). (remember the majestic dash has it's systems completely written outside of FSX)

5)Last but not least have a proper set of controls where you can manage full range from way back (reverse thrust) through beta to normal advancement of controls. Makes a HUGE difference.

So as a starting point I suggest you try Google. It is a wonderful instrument that might enlighten you a LOT.

Edit

By the way: Just for your input this plane was developed with direct input from Viking air. Maybe do a check on who is Viking air.!

"The new development of the turbines, the cockpit instruments as well as the hydraulic and electronic systems has taken place in an intense co-operation with the Canadian aircraft supplier Viking Air, a specialist in the manufacturing of Twin Otter aircraft. Tons of expertise and the love of detail has also come from the Twin Otter specialist André Äpfelbach."

Just search "Aerosoft twin otter and you will find over a well over 50 posts on the twin otter.
