Hello. i am new to flight sim, but have been able to go through and get the student license and the pilot license pretty quickly. ive now done enough tests and have been learning instruments. in the cessna i am able to understand the VOR readout and fly into the localiser, make a turn to the corect heading and land the plane using the localiser and glide slope. but when i fly a jet, say a 737400, i just can not work out how the localiser works. i am flying in the air 20miles from the airport and ATC tells me to stay at 3000 feet and ill hit the localiser, but the Vor doesnt seem to change, i dont have any needles on it which represent what i saw on the cessna. is there something else im supposed to do to get the needles so i know where the localiser is. do i have to use the radio stack and other things? i cant seem to find definitive answers in the Learning Center, is there a resource that someoen can point me to or help me out. im sick of being on target and then being told ive flown over the airport!
1. ATC should give you a long clearance for an approach when you are roughly 30-50 miles away from them. Note this is for IFR so you obviously need to be tuned into ATC etc and the airport you are landing at.
2. Go to the map and double click on a runway that has a green feather pointing in the direction of the approach. (If you do not see any ILS feathers, then make sure you have selected them at the top of the map). Once you have double clicked on the runway, a list will appear, with the frequencies for COMM (i.e. clearance, ground, tower etc) and NAV (i.e. ILS approach frequencies) as well as ILS headings and the elevation of the airport. You will be given a runway to land on in point one when they give you clearance. Find the ILS frequency next to that number. For example, ATC tells you to land on runway 9L at EGLL, so on the map you find the ILS frequency (110.30). Also find the ILS heading and remember that as well as the frequency.
3. Open up the radio stack and type this into NAV1 and make sure it is in the primary position, meaning it is on the left as opposed to the right of the two dials. This can be done by pressing the <---> button in the middle of them. At the bottom of the radio stack, there should be a row of clickable buttons, namely COM1, COM2, BOTH, NAV1, NAV2, ADF, DME etc. Click the NAV1 button as to illuminate the light. Then type the ILS heading into the course indicator probably on the AP panel. This means that the ILS is now set up, and you should begin to hear the Morse code identifier.
4. Now, once you approach the airport you must switch the toggle button of GPS/NAV to NAV. This is the only way the ILS will work, so make sure you have done this. Switching this toggle will enable the ILS to work, but will disable the GPS waypoints navigation. So if you are using AP then switch from one form (GPS) to the other form of navigation (NAV).
5. As you get closer to the airport, you will now be hearing the ILS Morse code identifier and you should be roughly on course, according to the HSI (but only if you have remembered to type the ILS course into the course selector). You will soon enter the glideslope pattern where you will need to slow down considerable to stay on it, about 180 MAXIMUM in a jet.
6. On the attitude indicator on the right and bottom side or similarly on the HSI, white indicator lines shall appear, with a pink triangle on both the vertical and horizontal set of lines. The big line in the middle is the centre of the approach and is the correct glideslope. If you are too high, the triangle on the vertical axis will be below the middle line and vice versa. If you are too far to the left, the line will appear to the right of the middle bigger line, indicating that you should turn to the right until it centers. To put it simply, fly towards the lines as to centre them.
7. Once you are roughly on approach and have been given permission to land you can use the autopilot. If you do not want to, then just carry on using the method above of centering the plane yourself and reducing speed and flaps etc. If however you do want to use autopilot then click the APP button, making sure the HDG button has disengaged itself and the toggle switch is on NAV. Deactivate the whole AP system at 500 feet. I hope this helps. Do not forget to lower speed in the approach and lower flaps and auto brakes/spoilers etc.

Hope this helps
thanks heaps for that detailed instruction. thats made it a lot more clear. ill print that off and have a go with it tonihgt... i didnt realise i had to enter all deatils into a radio stack etc.
No problem, let us know how you get on
