BOAC,
I'm not sure if I 100% get your idea... But in my view it does indeed matter. Why? Because if you hear "on course and glideslope" with the
correct range, navigator may see that this range does not match with their height. Or others of the crew may feel/understand this by their intuition, as they know their height. Hence, there is a possibility to understand that something is wrong. But if you are given both a mistaken "on glideslope", in combination with a wrong range.. Then you are totally deceived.. No chance to catch the error. If you see what I mean.. Both data are wrong. But since both are wrong, they do not contradict your height. But if only one of the data was wrong, the data would "not make sense"..
Does that make sense ?
