Every aircraft has an approach speed and every approach has its own localizer and glideslope intercept heights.

Approach speed is typically in the high double digits or low to mid 100s depending on aircraft, weight, etc. Localizer intercept...typically a couple thousand feet up, depending on the approach, how the final approach course was entered, etc.

Perhaps, I don't understand the question, but it's really dependent on the approach for the intercepts of glide slope and localizer. For the speed, it is aircraft dependent.

For the 744, depending on gross weight, the average approach speed would be around 155KIAS. At Changi (WSSS), 02L/C you're generally vectored in anywhere between 10-14 miles to intercept the Localizer at around 2500'. Your glide slope intercept on those approaches is generally just before 8 DME. Obviously, if you were vectored in higher the intercept would be further out (every 1000' would be just over 3 miles further out) and the converse would be also true.

Again, I'm not quite sure what you're asking, but if that isn't what you're looking for perhaps you could rephrase the question.

It's impossible to answer this without giving some more detail - as already said above it'll vary significantly depending on what approach into which airport you're talking about...

As Star world said, we need a little more detail. It depends on the airport.

As a rule of thumb, you want to intercept the glideslope from below in order to avoid catching the false glideslope.

Other than that and what Philsquares wrote, I don't know what you really want to know.

You could possibly type out the question in a sentence  Big grin

And check back in from time to time to acknowledge the answers.
