The FAF on any ILS is the intersect of the glideslope with the lowest published intercept altitude
For a precision approach, the altitude at which you'll be vectored must be not less than the glideslope intercept altitude
at the planned point of intercepting the localizer.
43) In fact, the authors' simulations show that using only proportional navigation, without requiring ranging to the warhead, allowed lower-tier interceptors to engage successfully at a 20 km intercept altitude
if launched within 70 km of the warhead's target--and at a 10 km intercept altitude
if launched within 30 km.
There was a land -- versus sea -- breeze which meant aircraft were landing to the north so we continued on a southerly radar downwind heading as we descended to glide slope intercept altitude
Since you're starting significantly higher than the published glideslope intercept altitude
, you've managed to locate a false glideslope.
The most common area of fusion I see among pilots flying a vectored or straight-in (no procedure turn) final approach course is determining when it's safe to descend to the initial or intercept altitude
That gives you time to get established and down to the intercept altitude
One airplane turns inbound, and the plane above/behind it descends to intercept altitude
for its turn at the approach.
The hold is at 2600, which is the glideslope intercept altitude
As far as assigned altitudes, when the approach is an ILS, the controller can't park you above the glideslope or below the minimum glideslope intercept altitude
for the approach.
The VGSI can only be received out to 4 miles, whereas the ILS glideslope intercept altitude
