# intercept altitude

## intercept altitude

As used in astronavigation, it is the difference between the minutes of an arc, between computed and observed altitudes, or between precomputed and sextant altitudes. It is labeled T (toward) or A (away), as the observed or sextant altitude is greater or smaller than the computed or precomputed altitude.

The FAF on any ILS is the intersect of the glideslope with the lowest published intercept altitude. In this case, that's 7800 feet, which happens to be coincident with--but isn't defined as--DOUMA.
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. What if you intercept the final approach course 20 miles out?
That gives you time to get established and down to the intercept altitude of 2300.
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. However, glideslope crossing altitude is 2536 at HISER.
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 is 4.8 miles from the runway.
This time, they cover nonprecision approaches by telling us to report "leaving the final approach fix inbound." Ok, so we have one paragraph that compels us to report leaving the minimum glideslope intercept altitude (on glideslope) when conducting an ILS (lightning bolt symbol for you Aero Nay users) as well as to report crossing the Maltese-cross symbol on a non-precision approach.
