Hey guys,This will maybe sound stupid, me being a reviewer and all, but I can't for the life of me understand how to do ILS landings with the CS757. I just don't get it. As a matter of fact, the entire A/P just keeps eluding me. I engage the A/P, engage ALT HOL, engage SPD, engage HDG, and I tune the ILS frequency and course in the ILS config panel thingy on the pedestal. I then fly the pattern, bringing the aircraft in front of the runway, but the A/P doesn't line me up and doesn't do anything with the G/S. It just flies right past the runway, and if it catches the ILS signal, it only starts flying into the respective course, completely disregarding, it seems, the origin of the signal. It doesn't line me up with the runway and I can fly right over the airport, parallel to the runway, but not lined up and not on the G/S, even though I engage APP mode... It's driving me insane, because I just don't understand what I should do, and since CS doesn't provide any tutorial whatsoever, I feel completely helpless on this one. Could somebody please tell me how this A/P, and especially the ILS landing, works on the CS757?

My understanding is that the autopilot works when using the CDU/FMC config only. If you don't want to mess with the FMC, you can manually input the runways frequency into NAV1 and it should capture the ILS 'manually' so you can fly the aircraft in manually and while staying on the glideslope. Make sure the autopilot is disengaged if flying manually. I did an ILS landing into Albuquerque last night w/the CS757 and it worked like a charm using the CDU/FMC.Best regards,Jim Young

Make sure u are tuned into the ILS frequency and heading by pressing the navrad button on the FMC. Also you have to hit the LOC button on the MCP first and once you have captured the localiser,then and only then press the APP button to get the glideslope. Sounds like u may not have the correct ILS freq/course punched in or u are just pressing the APP withoutfirst catching the localiser.Hope this helps.Alex

I feared you had to use the FMC/CDU in conjunction with the A/P APP, but here's a quick rundown of what I'm doing:1) takeoff; engaging HDG, VS (climbing to an altitude of 3000), A/T at 200kts.2) I fly the pattern, meanwhile tuning the ILS and setting the course of the runway I'm gonna land on (I did this at Birmingham EGBB: ILS 110.10, CRS 330). I dialed all of this into the small ILS panel on the pedestal.3) Once on baseleg, I engaged LOC, and waited for the A/P to line me up.4) In the end, the plane indeed turn, but just towards the CRS I had set, and it didn't really line me up with the runway. I then engaged APP, hoping it would help, but nothing really worked. It just kept flying the way it had flown earlier on, not doing anything differently, really...Based on this, I think you both are right in my mistake: I did nothing with the FMC/CDU except aligning the IRS before takeoff. So, what exactly am I supposed to do with the FMC/CDU?(And thanks for the info you guys already gave me!)

Are u getting the LAND 3 green lights when u have turned on the APP? Try a different airport in a different country and see if it does anything differently.Alex

I have found that even thought the FMC will autotune the nav radios, I have to also input the ILS freq and final approach course manually in the #1 NAV radio. Open the radio stack and you will see 3 nav radios, switch them to Manual mode then set them. Once the LOC indicator starts to move, push the APP button and it should turn on course. If your altitude is correct, below the GS, when it intercepts the GS it should descend on it. You can either let the AP land, or disengage it at around 500ft AGL and hand fly to the landing.For some reason the FMC also doesnt set the proper speeds for me when using VNAV after the TOD, so I also manually set the speeds and approach altitudes in the FMC, see the manual if you don't know how to do this. Usually the altitudes are correct for the waypoints but the speeds are way too high. Of course if you use the SPD option on the AP, just dial in the speed you want as long as you are using the autothrottles.Hope this helps, the 757 is a great plane

I'll try these suggestions, but I think I'll just ahve to learn the way the A/P works. It's clearly quite different from the other planes I have been flying, like the Boeing 737 (classic and NG). By the way, how similar is the B757 A/P to the B767 A/P?

When you're flying heavy's like the 757 you should learn and use the FMC. You'll get so much more enjoyment! If you want to fly manually entering the ILS into the NAV1, fly the Piper's! The FMC looks formidable but it's actually very simple to use, especially the CS version. Here's what I do: -- Load the CS757 using one of the flight plans I have prepared. Once loaded, I set the IRS alignment switches to NAV immediately.-- Goto the 2d panel and open the CDU. Press POS INIT. Enter the airport I'm at - KLAX, then look down at the GPS POS - click the 4th button down on the right, then click the 5th botton down on the right (the sets the INERTIAL POS). Click on botton next to Route which takes me to the Route Page.-- Route Page: Click on button on left next to SEND. This takes me to the Flight Plans page and I click on FLTSIM FPLS button. I use the Next page button on the CDU to goto the flight plan I want to load - KLAX-KSFO, and click on the button next to it and it will load the flight plan with all waypoints. Press the ACTIVATE button which is the 6th button on the right. The EXEC light will come on and I press it and the light goes out. I then click on PERF INIT button again the 6th button on the right side.-- PERF INIT page: This takes me to the most difficult page IMHO. Using the numerical buttons on the CDU, I enter 150 and then press the 3d button down on the left to enter ZFW. That will automatically complete the top box - Gross Weight for me.-- I always enter 10 for the RESERVES and enter the CRZ ALT that I stated when I originally prepared the flight plan - 280 (for 28,000). In COST INDEX I enter any number, usually 50.-- I then press TAKEOFF (again the 6th button down on the right side). This takes me to the TAKEOFF Page.-- TAKEOFF REF Page - I enter 20 for the FLAPS and will immediately see the speeds for V1, VR, and V2. To activate those speeds, I have to press the buttons next to those speeds. For CG% I enter 23 (this is the trim and it works well for me; you can put 21, 22, 24% in there too).-- I then see PRE-FLT COMPLETE.I then close the CDU and begin setting all the other switches on the panel, like arming the A/T; setting the takeoff heading and altitude that ATC provides. I also make sure all the warning lights have been extinguished and begin my taxiing. During taxi I set the flaps to 20 (don't worry, you'll get a warning siren if you don't configure your flaps before takeoff!). I also activate the VNAV button so that when I eventually hit the CMD button, it will begin the climb. At takeoff, I simply hit the EPR button and the CDU takes over. At V2 I'm pulling back on the stick and beginning the climb, raise the gear and gradually begin raising the flaps. At about 1000 feet, I hit the CMD button and the CDU pretty much takes over everything. All that is left is activating the LNAV button when ATC says I can fly my flight plan. Nothing else to do except watch the instruments and sightsee until the top of descent (TOD).Just before the TOD, make sure you lower the altitude setting on your panel (I usually take it down to 4000). Don't worry, the aircraft won't start descending until you get to the TOD. I usually disable the VNAV just before the TOD and manually enter the Altitude and V/S as it makes for a smoother descent. I can also control the speed of the aircraft by lowering the speed on the panel. I take the aircraft down to about 4000 feet or until I engage the APP which will automatically control my descent down the glideslope to the runway. On the way down, I go back to the CDU to enter the runway I'm landing on, usually 28L at SFO. I click on the DEP/ARR button on the CDU and it opens the KSFO ARRIVALS. I look for 28L and click on the button next to that runway. MOST IMPORTANT: I go to the LEGS page by clicking on the LEGS button. I look for discontinuities (and there are always discontinuties). Your capturing of the glideslope and subsequent landing will not go as planned if you do not get rid of the discontinuties. To get rid of a discontinuity, click on the left button in the LEGS Page just below the word "DISCONTINUITY" then click on the button just above the word. DISCONTINUITY will go away if it's successful. I then Activate this plan and click on EXEC to turn out the light on the CDU. Lastly, I goto the VNAV page on the CDU. It will show me all the landing speeds and the last one on the page will be blank. I simply click on the right button next to the landing speed with full flaps (usually 139/30) and then click on the button next to the blank speeds and that will enter the landing speed the computer will compute for my landing. Again, this is important as it will mess up your landing and glideslope if not properly completed. I close the CDU and watch my descent and heading. When I have captured the glideslope, I click on APP (Note I do not use the LOC button, just the APP). Once the APP takes over, I begin lowering my speed to 139 and start lowering my flaps to 30; but I make sure I lower the gear (about 10 miles out) before I lower the flaps or I'll get all kinds of warnings! I sit back and "relax" and watch the descent to the runway. I also set the Autobrakes to MAX and arm the Spoilers (Shift+ the Slash / key). At about 200 feet before landing on the runway, I turn OFF the A/T ARM so that I can control the speed once the aircraft has touched down. At touchdown, I hit the F2 key to activate the reversers and bring the aircraft to a halt. I then disengage the A/P and raise the flaps and begin the taxi to the gate. Passengers cheer.... :( Hope this helps.Best regards,Jim Young
