Well,

I've been practicing instrument landings using the GPS in 1 mile visibility and have got them down pat. The Howard is nice and easy to land :d (so long as you remember the gear :banghead:)

So, now I can do those bad weather legs as well :applause:

Now onto ILS landings

I thought I'd move my responses into here as it is probably more appropriate in here.

Thanks for the advce from yourself and others about using the Approach features in the GPS.

Makes lining up a whole lot easier and much quicker in poor vis than circling around looking for a runway.

I am able now to set in an approach and let the AP take directional control all the way onto the runway. I was controlling the aoa and throttle just to keep ontop of things.

On the field that had an ILS I was put nicely ont othat and the situation gauge gave me a nice indicator to adjust my rate of descent to.

I had only one problem.
Following the AP all the way down I was not put on the tarmac but slightly off to one side.
Is that how it should be or is that a case of M$ not getting everything lined up just right.

It wasn't a big issue as the Spit I was in prefers grass to the hard tarmac :) A little side slip just before touch down put on the hard stuff if required!

I have a feeling that is a problem with the Auto Pilot (if I read correctly that you let the Auto Pilot do the nav and you were controlling the throttle). I was flying the opposite, me handling the nav, and the Auto Pilot doing the descent :d and I was lined up perfectly. you just need to make sure that the bottom most field on the left reads 0.00 nm. Then you know you are right on top of the approach path.

I have noticed the same with the Auto Pilot at altitude, if there is a little bit of a cross wind. It will fly the nav heading untill it is too far away from the course, and then correct back, rather than having a wind correction figured in. If there was a little crosswind, then the Auto Pilot probably didn't correct cause it wasn't far enough away.

That would make sense. There was a slight crosswind. Mostly from head but a small crosswind component. Not enough to worry about but perhaps enough to confuse Otto. I'll take the helm before the threashold in future.
I was letting the GPS control the nav as it got it lined up very nicely from a long way out as soon as I requested the Approach as active. The wind was very bumpy on the descent making it somewhat harder to hold course manually.

I also didn't have the GPS showing but was rather following the nav gauges I have installed. I'd show a screenie but FS/pc just crashed and rebooted!
I'll add on when I can.

Okay,

Personally I have the GPS open, as it is easier for me to follow and adjust too. I don't have any experience using the guages for an instrument landing, so I don't know how much I'll be able to help.
