Hi, Apologies if this has been answered elsewhere, but I haven't been able to find the answer. When you set up VNAV for a Skyview GPS VFR approach, you enter the distance and "altitude above the threshold" that you wish the Autopilot to fly you to. My question is assuming that the barometric pressure (as opposed to GPS altitude) is used to determine this then should the Baro be set to QFE or QNH? It's confusing to me as (in the UK) its not normal to talk about an altitude above the threshold - its either a height above the threshold or an altitude (above sea level).
Also secondary question, what happens when this height (altitude) is reached? Does the autopilot level off or continue the descent? What is the relationship if any to the Altitude bug or the setting of the Minimum Altitude?
Many thanks
