ILS decent too short help!

Featured Replies

Hello,I need help, iam flying the 757-200 using the ILS to land...And sometimes at some airport iam not able to land on the runway it decent to fast and i reach minimums way before the runway... the speed at which this is happing is almost the same 133kt and so far it only happends at germany airports like: eddf, eddk (aerosoft)Can some guru advice me?I have FSPassenger btw,so yesterday i tried it again but this time i went with a faster approach @ 154kt and i made it to the runway but because i was to fast i coulnt bring her down gently and i blew a tire...Now i know how to fly and ILS (moslty) and what i need help explaining or tips is how to decent at the right rate when using the ILS glideslope and what speed should i be using most of the time?I really hate when that happends can someone please help me understand what iam doing wrong that in that particular approach eddf eddk that i always land to early of the runway and crash on the guiding lights...I guess i should be using a speed between 133kt to 155kt to land at this airport (iam only having the problem at those 2 airport every other ils landing goes great when using 133kt, could it be because those airport are know of winds or crosswind or something?)many thanks

Really this is one where you need to get the books out (i.e the pilot handling notes for the aircraft, which will tell you the correct V-speeds for any given landing weight). They will either be in the PDF manual for your aircraft, or you can find the data online, or you can open the aircraft config file in FS with notepad, and find the data there.But, as a rough guide, this should help: You need to know Vref for your aircraft (Vref is the speed at which you should cross the threshold when landing). When you know that, you can work out your correct speed for your weight.Typically, Vref is approximately Vs plus 30 percent (Vs is the minimum controllable speed before a stall). But, those speeds are not what airliners are typically flown at. In light winds an airliner is usually flown at Vref plus 5 knots (with flaps 30), whereas in windy conditions, an airliner is more likely to be flown on approach at Vref plus 20 knots.All this is to give a bit of margin for error on a wind gradient as you come in (wind gradient typically causes the headwind to drop as you get lower down, owing to the wind being slowed down by interaction with the ground, so your airspeed typically drops a bit as you get nearer the runway and your groundspeed increases). In very windy conditions where serious wind sheer may be a factor, you might even come in faster and steeper than normal, to ensure you have speed and inertia on your side.If all that V-speed stuff is confusing you, here is a helpful guide to it: http://en.wikipedia.org/wiki/V_speedsHope that helps.Al

wow perfect reply..thanks for the info i can now lookup the vref and pratice..thanks

i reach minimums way before the runway
Now what's the problem with that. Usual CAT I minimum is at least 200 feet. TCH should usually be around 50 feet. So of course you will reach minimum before the runway. Does obviously not apply for higher CATs, and is way worse on any non-precision approach.

130 kts.All purpose FSX vref for jets :-)Somewhat tongue-in-cheek, but when in doubt I don't think I've ever had a disaster shooting for 130 knots and adjusting from there. Not in a Cessna, though.Something worth repeating for newer simmers is you control your up-and-down on the glideslope with your throttle, not your normal up-and-down controls. Give yourself plenty of time to get set up. If you need 15 miles, take it, then you'll get better and need less space. Once you get properly set up (flaps, gear, trim, throttle) a good airplane will coast down the glideslope without drastic intervention on the pilot's part (assuming no challenging weather).Many add-ons will tell you what your v-ref is. It might be on the approach page of your FMC. Others have speed cards that pop up. Still others it is in the documentation. The main variable is the weight of the aircraft at landing.It is a lot of fun to practice ILS landings. Just program a very short flight between two close airports. I like to use KLGB (Long Beach) and KLAX (Los Angeles). You can program an entire flight including an ILS approach that takes well under half an hour. Alternatively, you can just do touch-and-goes at one airport, but you get better practice the first way, I think.The worst way to practice ILS landings is at the end of a 9 hour flight :-P It takes a lot of practice in each airplane to get it right.

you said you approach at 154 knots so that you should be at 133 by the time you hit runway, this suggests to me that you glide down to the runway instead of flying doen to the runway.By fly down to runway, i mean, always maintain speed and flaps that allows you to fly a bit higher or lower as you need in your glide slope following. always approach slightly below the glide slope, cause you can still land if you are low than if you come in too highI prefer to save a flight when ILS is captured, and do my landing practices with that saved flightMaintain speed and flaps that aloow you to fly down, and not glide down, cause you got more control of the plane when flying down to the runway as opposed to gliding down.Increase sensitivity of Elevators to ensure you have strong control over elevators, and add some null zone if right sensitivity is not balanced when controls are centered.By flying down, i mean, throttles are not fully idled till the rear wheels have touched down, and at everypoint along the glide slope flying down gives you the opportunity to make altitude corections you would not be able to make if you were gliding down, cause you dont have enough speed.Go to full flaps gear down a bit early(i do this about 2000 feet AGL), cause flaps allow you to fly slower, and hence you have more time to make corrections at lower speed.In the early stages of approach try to trim your elevators so that you can almost leave the joytstick and the plane will still stay on the glideslope. For this you need to have elevator trim buttons in very easy to reach location. This means you need to make fewer adjustmenst further down the line.Trim Trim Trim, No matter the flying situation, trim first, this puts the plane in a much easier to fly attitude, and you only need make little adjustments.Trim for TakeoffTrim For ClimbTrim For approach/GLide slopeSince i worked out how to trim, and put the trim buttons on my joystick, all phases of flying have been much much easier.So when landing, if the speed is right, say 133 to 155, but the plane is still heavy to put nose down, then from this point centre joystick and keep triming down till plane is roughly following glide slope, from here adjust power and elevator as required. But once trimed the elevator adjustments youll need to make on the way down will much less, than if you had not trimed for landing. ALso triming the plane up a bit gives extra lift that allows you to make a softer landing at slower speed.That is what i do

Your elevator trim should be mapped to the two side buttons on the top of many joysticks. I use left for up, and right for down (that just seems natural to me). Be sure to drag the slider to the right on your joystick control from within FS so it is a continuous action as long as you hold the button down. (I have four such buttons on the top of my Logitech Extreme 3D Pro; I assign left and right brakes to the smaller pair.) That way it is easy to give your trim a blip in either direction. Just enough so the airplane is descending or climbing the way you want without pressure on the joystick. Don't overdo trim. Just a blip, ease off the joystick pressure, and see what the airplane does. Repeat patiently until you don't even have to touch your joystick to maintain the desired descent.Trim is probably the most neglected part of most peoples' virtual flying.The main thing is, don't short yourself on distance from the runway start, because it takes a lot of time to get set up properly at first. And you shouldn't be pushing your joystick forward along the way (if you have to, you are coming in too high or fast, although I have been guilty of some pretty scary dives on final -- very sloppy flying.) Use your throttle and sort of glide down like the poster above put it so well, once you find the sweet spot with your throttle. If you start to get below the glideslope, give yourself a little more power to let your airplane "catch up with" it. If you're above, take away some power. You shouldn't be monkeying with your elevator control until the very end, when you'll want to flare (pull back on your joystick some) just above the runway before your wheels touch down.Some add-ons will control your throttle automatically to set it a v-ref and pretty much land themselves. Autolanding all the time fmakes for lazy pilots, though :-)Make sure you are at the right flap setting, too. Generally, more flaps mean a steeper approach. Again, many addons will tell you what flaps you should use for different v-ref speeds and give you a choice, but you are going to have a lot more flaps for landing than takeoff, maybe even full flaps, depending on the airplane. A bad habit you can into in both virtual and real flying is to rely on your flaps to correct a sloppy approach. "My Cessna is coming in too high, really, so I'll just crank out full flaps to make my descent steeper." Or, worse, "Hey I'm coming in way to fast in my 737, I'll just throw out flaps and gear to slow down." Best to get set up properly and use flaps as intended. That way you don't scare your passengers or break your equipment.Also, don't forget to arm your spoilers ("shift+/") and set your autobrake if available, and be ready to hit F2 for reverse thrust. Again, you won't have those kind of options on small planes, but you won't need them either. A 77,000 kg jet has quite a bit of inertia to overcome, and that isn't even a big one.Practice with the Cessna until you get the basics.Let us know how you do, please. Becoming confident in the final part of the flight is the most satisfying part of flying, in my opinion, whether on the computer or for real. Anyone who has taken PPL lesson can tell you how great that first (non accidental) good landing feels, when it finally "clicks."After you get good at all that, use the weather options to set up crosswinds, working your way up to where you are decidedly crabbing into the wind at an alarming-looking angle to stay on the extended centerline. Reduce visibility to where you have to rely on your instruments. There's always a new challenge in flight simulation, which is why it is such a great hobby. Unlike other games, you don't learn how to beat the Big Boss on Level Three and that's that. You might not need all this, but someone else might be doing a search or run across this thread, so I apologize if I have told you stuff you already know.

 

 

 

Presumably you are using the inbuilt ATC!!!!!! Which doesn't give speed advisories which they shouldBasically at or below FL100 you should be at 250kts. When you get to within 30dme of your destination you should be at 210ktsAnything below 210 will require a flap setting on your a/cAs you turn on to the heading to establish on the localisor your speed should be 180 or 170when you drop the undercarriage plus flaps reduce to 160. At 4dme you should be on full flapsyour Vat is dependant on the a/c performance and weight typically say 130kts.To whatever your calculated Vat is you should add the required margin for crosswinds bad weather altitude temperature humidity etc.It's that simple!!!!!!Vololiberista
