Hi, thanks for the replies.
Zulu, you said
The glideslope is easily maintained by working out your groundspeed (IAS taking into account the wind) roughly and use the following formula: (Groundspeed / 2) * 10 - this will give you the approximate decent rate in feet per minute that you can obtain on your VSI... if the decent rate isn't enough or is too much then change it by 50 feet per minute or so... the glideslope is very sensitive...
so it is possible to change the GS decent rate? i cant find anywhere on the flight deck and option to do this.
From what you said I have a feeling i may have been flying the backcourse during that flight, because there was no GS.
cheers
