Why should you not do an AUTOLAND CAT I?. Is it neccassary to
write it in the SOP that you can do it?. Or is it better to write
you can`t?. If you restrict your operation by regulating everything
then you have no flexibility in common sense cases. I hope it
helps. We have dual channel APP in all CAT I and CAT II cases.
To disconnect the AP is really not a big deal. You know what you
expect when you push the button to continue manualy. We have
the HUD in all of our NG`s and that helps as well to allign the AC
in the slot and put her on the spot. The saving of fuel and brakes
pays for itself allone as you are able to fly the speed more
accurate and gate even flare guidance. It takes you a few times
until you get used to it but then you can grease her on as well.
The logic behind is that the HUD to point you to the Centerline
and the touch down zone.
