Heh when I did Peter McLeland's Cat3 tutorial in the Trident in FS it felt really strange... god knows how it must feel doing it for real

I can tell you Jonesey...For real, it looks just like in my tutorial and as you have seen, the visibility is far, far less than in that video. If you watch that video then when the voice says "10 feet" then in CAT3b Trident, you would only need to see one single light...not the whole Christmas tree of lights that were visible there in that video.

The settings provided in the .FLT and .WX files in my tutorial give a very realistic CAT3b view of things. The decision height was 12 feet radio, and the limits for the approach were Touchdown RVR 75 metres and MidPoint and FarEnd RVRs of 50 metres. The last two calls from P3 were "30 Above" (at 42 feet on the centre radio alitimeter) and "Decide" (at the 12 feet bug on the same instrument).

On that last call of "Decide", I had to respond immediately with "Land" or "Overshoot"...To make that "Land" call, I had to see ONE LIGHT.

If I said "Overshoot", or said nothing at all, the P2 slammed the throttles to the firewall and the aircraft would overshoot ON autopilot without actually brushing the tyres on the concrete. When you realise that at that "Decide" call the WHEELS were actually only 12 feet above the runway, then you can understand how remarkable that is.

BTW...On that last point they never quite achieved that in the Trident Simulator...If you slammed at 12 feet, the the wheels would just briefly brush the ground...Unlike the real aircraft

In that case Peter it is as Tonks' signature states 'IT'S NOT REAL'....more likely a case of 'AS REAL AS IT CAN GET'!!
