ILS approaches with 296.
As "Drambuster" reports the VNAV terminates 500 ft above the target altitude (page 40 of manual).
Seems to me the fix is to copy the airfield co-ordinates into a User waypoint. Then subtract 500 ft from the airfield elevation.
In the VNAV setup page insert 500 ft above the target waypoint and the desired descend gradient e.g. for 80 knots approach 400 ft/min (approach groundspeed multiple by 5). Remember on the Panel page "Options" VNAV indicator ON.
Project the runway centre line (page 75 of manual) to give User waypoint say 6 mls IAF. Now take your observer along and practise ILS's.
4 ml height 1275 ft
3 ml height 950 ft
2 ml height 640 ft
1 ml height 320 ft and DH 200 ft
[as mentioned by other posts above, the airfield reference point can be fine tuned for the landing threshold, but with almost one mile to go there is room for correction]
