Apologies, It seems I was not quite clear enough in my original question.

When you're in level flight about to intercept a glide slope from underneath as usual (whether or not I'm about to drop the gear here is irrelevant), the standard industry call (apparently) is "One Dot Above". Then maybe "Gear Down Landing checklist" etc.

My gripe here is that once you've established yourself on the slope and are descending, the standard calls for DEVIATIONS are "One dot above" if you're too HIGH....and "One Dot Below" if you're too LOW. We always reference the glideslope's position relative to the airplane...NOT where the instrument dot is on the indicator. That'd result in very poor situational awareness.

That'd be like saying "One Dot left" when you're right of course because the CDI is left....just doesn't make sense.

The call when you're about to intercept is an opposite philosophy compared to the deviation calls. Following me here fellas?

Glideslope alive. Then, if you're not on it you get above for high, below for low. I'm sure there are variations around the world though. I sure miss the sounds and lights of the marker beacons.

Wow that's confusing.

You get one dot high or low:

"Glideslope"

Response:

"Correcting"

Lateral error is the same:

"Localizer" or "track"

"Correcting"

I make it a personal challenge to intercept loc and g/s simultaneously without a level segment. :mrgreen:

Exactly what Donald said.

I'm rather surprised to see folks interested in describing the relative position of the desired signal, not the position of the aircraft.

Your position relative to glideslope.......then the glideslope position relative to you.

I would rather describe what I see in the cockpit (ie: 1 dot above when below g/p). That way, what I see matches what I hear.

In that case, you will see what you heard.
