Hello Jim.

I think the F1 GTN will provide lateral navigation control via the autopilot in the 737. It certainly does in the L1011.

When I get around to buying the 737, I will give it a go! (Real life keeps interfering with sim life.. :D)

The GTN has to be one of the best add ons. Although completely incorrect for the period 737-200, (or the Tristar) its a joy to use ;)

Vertical navigation in this model is where the challenge comes in. Without any VNav, its up to the pilot's arithmetic (the PDCS should have the figures) and flying skill to get the altitudes correct.

Cheers,

David

EDIT. Did anyone read the sign in front of the Captain, left side of the PDCS, above "GARMIN REMOTE BATTERY". It says "The GPS Equipment is not equipped for approaches within European Designated Airspace. I accordance with AMJ 20X2"? :-? Which GPS would this refer to? ::)
