| Welcome Aboard Flyaway. Glad to see you here. To answer your question we need to know a little bit about what air craft you are flying. When approching usually you set the flight plan to your destination from your origin airport. As a generla rule with most aircraft set your frequency as you have done with the correct settings. How did you get the ALS frequency? Did you get it within the flight sim? Or do you look for it on a map of that area? I looked at map of KIAD (Dules International) I wamted go by what the FAA had as the actual frequencies one of them did not work, I did not have a smooth approach but I did land and it wasn't pretty. If this is a heavy aircraft you are flying, it won't handle like a Cessna. Think about it and get back to us. Regards,
Ed

To get the frequency, I went to the map and clicked on the airport and looked for the runway frequency. I set an IFR from Heathrow to Boston. |

You're missing some basics of using th autopilot(AP) and you're in the wrong aircraft to learn. I suggest that you use the C-172. With that said, let's talk about a few basic items that assume you're trying to land using the ILS.
The ARR button only arms the approach mode of the AP so that as you cross the localizer(LOC) course, it will capture and track the LOC. It will not automatically align the aircraft with the runway from any direction or position. It has to be a runway with a ILS or LOC approach. You have to have the aircraft within the service volume(see below) of the localizer(LOC) and on heading that will intercept the LOC at the proper position(normally about 10 miles out and about 2000-3000 feet AGL with an intercept angle of approx. 30 degrees). AGL-Above ground level as opposed to altimeter altitude which is above MSL, mean sea level.
The ILS means Instrument Landing System but it will not land the aircraft(one exception). It's designed to get the aircraft to a minimum point from which the pilot must see part of the runway environment to land visually.

| Alrighty then. Very good explaination bravo. Had I known it was a 747 to begin with that would have helped me to help this person. You did a great explaination. I didn't know some of that but ya know you can always learn something on this site that is why I like it. Thank you CRJCapt Regards,
Ed

If you are too close to the runway - say less than 8 miles, the plane will seek the localizer as fast as it can. For example, if you are too much to the right, then the plane will lurch to the left. It will overshoot the localizer and appear to be leaving the airport. If you are farther back, it will correct itself and get back on track. Usually I try to use the APR about 10 miles out. But you should disengage the AP and fly to the runway manually when you get close. The AP and ILS are not designed to guide you right to the tarmac. |

just make sure you're not approaching back-course!  |

| I can capture the localizer (737 into Schipol) but I can't get automatic descent. My HSI shows the glideslope but doesn't capture it. I'm approaching at 7000 feet from 30 miles out roughly in line with the runway. |

Try 15 miles out at 3000 feet. |

You cannot capture a glideslope. Only the localizer. To automate your descent, first set your autopilot altitude to 0 feet (or any value lower than airport elevation). This will tell the autopilot to bring the aircraft down. Next set your descent rate on the autopilot to -700 fps. This will bring you down at a rate that closely matches the glideslope. If you come in too high, then reset your descent rate to -900 fps for example. If you are too low, reset your descent rate to -400 fps until it follows the glidslope. You can finally reset the descent rate to -150 fps as you get ready to touch down on the runway. I've done this many a time with the 737. It works like a charm. Just keep an eye on your airspeed so you don't drop below 130 kts. You basically will be flying the craft by turning knobs or clicking switches from the autopilot panel instead of handling the actual controls. Much easier and better landings! |
