Very nicely described Peter ! You probably don't get this in the sim, but if you load your procedure on the ground you'd immediately get a fuel warning and you'd see you'd need xxx thousand gallons to complete the flight. The reason for this is the missed approach procedure which is often a time or altitute restriction "From the missed approach point climb on runway heading to 2000ft before turning back to the beacon" etc. Because the GNS has no coordinates for that point in the procedure, essentially the ILS extends to infinity (I think I found the Southend 24ILS extends to the mid South Atlantic). So the all the maths around flight time and fuel burn gets screwed up.

What might work in the sim though is a near-VNE approach. Not every ATC'er is used to handling aircraft like the Cirrus and it happens that you can often be left high. So when you intercept the ILS you can find yourself doing 160-170 knots while you've been trying wash off height. Continue with the GS like this, and at 2 miles close the throttle completly. Unless you have a very strong headwind, you'll just about be over the hedge when you can feed first flap in, swiftly followed by full and land thereafter.

Cheers

Hi Rich,

It probably works in the Sim because at McLeland Field at least, the Missed Approach procedure turns back and joins the hold over MCL VOR...You can see that GNS picks this up and displays that holding pattern on the map and the map on the MFD...Also in the Sim, on declaring a missed approach to ATC you are offered "Vectors" or the "Published Procedure". If you elect "Published Procedure" then the GNS and Autopilot will fly it for you and join the holding pattern over MCL.

The Sim depends on properly coded Approach Procedures in the XML coding and I don't think that ALL the airports in FS9 were given that luxury. However, I wrote the coding for McLeland Field myself and it performs very well :flying:

Cheers Peter,

Perhaps you can team up with Nigel H J and try something like this next .....................?

Thanks for the explanation Peter, I will surely try this out this week.

Regarding the Activate or load option, is this simply so you can preload the system but not follow the plan until you select acitvate at a later time?

Yes Allan...You would normally "Load" the procedure on route and then you could "Activate" it when nearly there. In practice in FS, you get radar vectored to ALL airfields but this would not happen in real life :flying:
