Hi everyone!

After some time away from flightsimming, I've made a fresh install of my FSX, with all sorts of sceneries. And after installing plane after plane, where I couldn't decide which one to actually fly with, I ended up with the 7oh7... Again...

Anyway. Sadly for my wallet, I found some real 707 hardware which I might buy. First one is a real 707 autopilot, which pretty much corresponds to the one in the CS707, apart on one small detail:
The CS707 has one mode more than the real deal; "NAV". All real one's I've found just got "HDG", "MAN", "VOR LOC", "GS AUTO" and "GS MAN".

My question now is, did most of the 7oh7's have just 5 modes istead of the 6 like in the CS707? If yes, did the pilot's fly their 707 with Doppler/INS on "MAN" by manually turning the AP-knob, or manually turning the HDG-Bug on "HDG" mode, according to the outputs from Doppler or INS?

I'm asking because my plan is to get a real autopilot and to convert it for use with FSX. And because the real one only has 5 modes, i wouldn't be able to get all functions in FSX, which wouldn't be too bad if the real deal didn't have "NAV". So I would just leave it away.

Thanks for your help!

Aircraft not equipped with doppler nav or INS probably didn't have the NAV position on the AP mode selector. I have a TWA 720B manual and its AP is just like that.

One curiosity: on the Varig 707 simulator, which only has doppler, instead of NAV, the selector has a DOP position.

I have an AA 707 manual from 1978 that already have the INS.

This manual also had a section on the new experimental ACARS system installed on some 707s!
