>Actually, there is no such thing as a G/S echo :-). At no less than 5 miles out you should be established on a decending G/S.HTH,Mike T. If you are flying VFR to an ILS approach then simply look on your sectional chart which will tell you the minimum altitude you need to maintain to clear every object in each quadrangle of the chart. ATC will bring you down to whatever the FAF altitude is regardless of what your your G/S is doing. The morse code for the ILS is printed on your approach chart so simply match up the dots and dashes to what you hear, and, if its spoken to you verbally then even better.And YES you CAN descend before being established on the LOC, regardless of your place on the glideslope because you will be approaching the ILS with the GS above you (never below you). To verify that you are have tuned to the right ILS approach simply switch from COMM to NAV on your radio and you will hear the ILS approach morse code or verbal designation. "could be descending on a false G/S echo".Actually, there is no such thing as a G/S echo :-). You are heading in on the runway heading and your LOC is centered on the runway heading.You are now established on the LOC. You should now be banking to center the LOC needle on HSI 350 (mag var not withstanding) and aim to have the needle centered as the same time you roll out of your bank at heading 350. Your LOC needle will be deflected to the left and as you come within 10 degrees of 350 the needle will begin to move to the right (you have 20 degrees of deflection). Once you are on an intercept course to the runway heading (for instance you are approaching runway 35R from heading 310). You don't even need to follow the glidelope needle and can transition to visual and follow the VASI or PAPI in (white you're alright, red you're dead).So.To make a long story short. From an glideslope standpoint you can be on or ABOVE the glideslope on approach (never below). ATC is not concerned with the glideslope indicator because in most cases you don't need it to land since most airports have a standard 3.0 glideslope whether you are flying the needles or not. Both the localizer and the glideslope together form the ILS. Once you have tuned to the LOC frequency and the vertical needle becomes centered and you are showing a similar heading on your HSI (with wind correction angle applied) you are established on the localizer.Do NOT confuse the localizer with the glideslope which is the horizontal bar. Wow, you guys would fail the Instrument knowledge course:Established on the localiser means that you are:1) tuned to the localiser frequency for the desinated runway (not to be confused with the glideslope).
