Ever Had To Land At 180 Kts In Flight Simulator?

Mon Feb 18, 2002 9:01 am

It allways happened to me.
Original planes that comes with FS they don't have this problem, but when you install new planes, specially the heavys, in order to get the glideslope centered, you have to approach in abnormal speeds, till you are forced to land about 180 knots in case of a 747 for example.
Is this an error of Flight Simulator ? or some kind of incompatilbility with the ones you wanna install ?
Thanks

Do you land your Planes fully loaded with fuel?

Well, Try to Land with about 20% of fuel in every tank

on the FS taskbar click on: Aircraft then Fuel then put in 20% in all the tanks

nnnaaaaahh, there should be a more realistic way to dump fuel. isn't there ?

Nope you cant dump fuel in Flight sim...but that would be cool! Big grin

yeah, it would be very realistic. anyhow, thanks for you help, i'll try to light up the plane by doing this.

You could dump fuel if you had a fuel dump gauge. But I'm not aware of anyone having made one of those  Smile/happy/getting dizzy

I do approaches at 180knts, and when im on finals im still around 170knts....by the time i touch down im at around 150-160knts......btw, i have never used ILS because i like to fly everything manually, can anyone tell me how to get it all set up?

EGFF, There's a great tutorial In FS on how to do ILS Approaches.

You're not trying to land a 747 like a CRJ are you (nose down pitch on final)?

Typical approach speeds for the 747 are around 150kts with Flap 30 (it can vary anywhere from 140 to 165kias)

Here's a tip. When approaching, try & also keep the nose 2.5° up - that's realistic flying. It'll help keep your app speed down as well.

Cheers,

Justin

Once landed an MD90 at 190 knots. Not needed, but was so busy figuring out a new panel I forgot to change the speedbug to approach speed and later to turn off the autothrottle  Smile
Overshot the runway and came to rest in the water beyond (no, not Meigs).

Skystar, as i noticed before, i realized that my problem is that i was landing with 80 porcent of fuel. i got to have 20 porcent and i wont need to land at high speeds.
As regarding what you said, keeping the nose up to 2.5 deg will be realistic and hard, remember that you have to keep a 300 hundred feet per minute descent. so it's kinda hard , but i will try.

300 ft/min sounds a bit low. A good rule of thumb for a 3 degree GS is the airspeed times ten divided by two. I e, at 130KIAS,

VS=-130*10/2=650 ft/min.

I don't think the problem is the fuel, I always land high fuel and I can still land at 140-160 even with the heavies. I think the nose pitch might be the problem.

Nose pitch shouldn't matter (ie. trimmed..), but I can't see that anyone would not learn to keep the nose up on approach.

I've found, with 70-100% fuel, you need to keep the nose pitched higher to maintain descent rate below 100ft/min and always leads to a very high nose touchdown. With low fuel, its alot easier to perform an approach and landing with the nose relatively low, although i've noticed the speed bleeds off far too much.

Actually, dumping fuel is not realistic in an airliner. The PIC uses an E6-B and charts to determine how much fuel is required to make the trip, plus more for a diversion. Therefore when you are landing you have the correct amount.

Fuel calculation is an artform and usually done with the FMC these days.

Fuel dumping is very realistic in an airliner, although not in routine ops of course. MTOW (Maximum Take Off Weight) is often higher than MLW (Maximum Landing Weight) so in case of a malfunction before enough fuel has been burned to put the aircraft below MLW, you'll either have to dump fuel or hold while burning off fuel if you want to avoid an overweight landing.

A pitch up attitude of two degrees or so on approach is in fact quite typical of most airliners. What you really want is to fly a specific angle of attack on the approach. Combined with a glide slope angle, this pretty much determines the pitch attitude. The variable that can be adjusted to make this work is the airspeed. A heavier aircraft will have to fly faster to remain airborne. Approach speeds are calculated by the FMC or looked up in speedbooks depending on aircraft weight.

It is also worth noting that a heavy aircraft will have to start its descent earlier than a light aircraft since it won't be able to descend as fast without overspeeding. If you want to get down faster, you'll have to increase drag by using flaps or airbrakes. Some aircraft are very slick and hard to get slowed down once you are on the glideslope, making the crews reluctant to accept high speeds from ATC while inbound.

Cheers,
Fred
