ILS Approaches
EHM-0654 Murray:
Found a really interesting PDF in my searching for the "3 to 1" guidance.

EDIT: In attempting to print this here at work, I've noticed that the PDF was damaged. Is fixed now.

And you will find all the info you need for the actual app conducted in the ILS plate.

Good Info, I did find the above ILS approach quite useful, I have been doing something like that only, but was not sure of the time I should release the AP to OFF. So now I will look for the Inner Marker and quickly turn this off.
Approach plates are quite cryptic, but I managed to get one page on Vatsim which did some good explanation on the Approach plates, and after that I am like a little more comfortable when I look at the approach plates. However for me too there seems a lot to learn.
ILS is a wonderful tool, especially when you are low on visibility. I plan my descent and my approach to the ILS cone from very far and hence normally line up in line with the runway very early. I lock my ILS frequency and click on App button which does the final lining up to do a straight landing. The only thing needed to control is that when you hit the green cone on the GPS window, you speed should be very close to the required landing speed + 10 kts max. That ensures that the plane does not start rocking around too much in making the final landing adjustments.
Lastly its a good idea to put the guides on. In the Aircraft Menu, Visual Flight Path, (click on Enable Visual flight path after the ILS freq is entered into the Radio Panel) ,lock that to the Nav1 Radio and you will get rectangles coming up showing you exactly whether you are in line or not. Try doing it for a while and then you can use your stick / keyboard for doing the landing, without locking to ILS and APP, thats what I love doing now. I practiced enough with ILS locked, now with the NAV guides, I managed to keep my plane in the Cone. Ofcourse I try that on my favourite planes only and keep big birds above 737 only on ILS.
For all this I make it a point to make sure that I have the NavLog printed / written down from the Flight Manager thats built in into FS 2004 itself. I make sure that I have a notepad where the destination frequencies are copied and kept as well.
Hope this info helps and thats the way I fly :> and make my flying more interesting as well. Would love to hear comments.
EHM-1671 Ben:
I have been using Murray's 3 to 1 rule for about a year as a general rule of when to descend and how fast to descend from cruise altitude - I like to add about 10 miles on to the 3 to 1 total as a safety precaution ;)
As for ILS descent rates, if you've intercepted the frequency and are tracking the runway I like to descend at about -800 feet per minute. If I'm to high I may descend at a rate as high as -1000fpm, and if I'm too low I'll descend at just -200fpm - sometimes I may even level off - and wait for the glideslope to 'come' to me.
Hope that helps, and happy flying ;D
