Recall going into Crete one day in the 1980s about number 5 or so in the sequence to join right base visual for the westerly runway. Greek controller working like a one armed paper hangar with departures as well (same track).
In the middle of the RT fracas Danair ahead of us calls up requesting the QFE - a rather exasperated controller replied "Danair XXX the QFE is five millibars less than the QNH".
Wouldn't it be nice if there was only one altimeter setting... You could call it 'altimeter setting' All the terrain on the chart including the airport elevation would match the altimeter. All airspace delineations would match the altimeter at all times. Every plane of interest would be on the same setting, and would be individually responsible for keeping their altimeter accurate using widespread sources of airborne aeronautical data. Eventually you'd have a difficult time finding a pilot who would know what Q-this and Q-that meant, because it would be archaic nonsense.
Silvaire1 - love the irony and am with you all the way.
In the days when we operated QFE you could almost take a £5 bet on seeing an altitude bust in the event of a missed approach in the simulator. As soon as we changed to QNH it became a rarity.
