Commencing conditions e.g. Callsign M52 level at 2500ft AAL 30deg intercept from left most configuring done and it goes something like this:
ATC: M52 Turn left heading 270
M52: M52 Left heading 270
ATC: M52 slightly left of the centreline turn right 2deg heading 272
M52: M52 Heading 272
ATC: M52 approaching the glidepath do not acknowledge further instructions.
ATC: M52 Commence descent now for a 3 degree glidepath.
ATC: On the centreline turn left 2deg heading 270.
ATC: On centreline, slightly above the glidepath, adjust your rate of descent.
ATC: M52 on the glidepath on the centreline at 5 miles from touchdown, check your gear down and locked.
ATC: Slightly right of the centreline turn left heading 268
ATC (on tx & patch to tower): M52 at 3 miles to land TWR: Clear to land
ATC: Slightly below the glidepath adjust your rate of descent
ATC: On glidepath on centreline turn right heading 270
ATC: Approaching decision height, look up and take over visually, talkdown continues (that's the good slightly cheaty bit)
Leavesden used to do a good talkdown which I used when LHR weren't taking air taxis.
However, doing a talkdown on say, a Phantom with the lift augmentation u/s or a Lightning you wouldn't have time to get all that chatter in at a normal relaxed pace
