Can someone please explain how to use the autopilot? Specifically how to get it to follow waypoints on its own? Right now, I have to manually correct the heading either through the stick or through the HDG on my instrument panel at each waypoint I come to. I figure there's probably a way for it to follow the ground transmitters (not a real pilot, sorry!) just like it does when you follow the ILS on landing. Am I wrong?

To use the Autopilot, you have to activate it, and set the correct values in the Mode Control Panel (MCP), Altitude you are ascending or decending to, vertical speed and heading.
To set speed, activate the autothrottle, and set desired speed in knots when decending and ascending, and speed in mach when reaching cruising altitude.

As for automatic lateral navigation, it depends on what kind of navigation instrument you are using (GPS, FMC?)

If it is a original aircraft in FS, you have to use GPS, and set up a flight path. When this is done (read how to do it in the learning section in FS), press the nav button (I think, not flown the original aircrafts in months), then it will follow the flight path made on the GPS unit.

If you have an payware aircraft, and it has a FMS, you should probably read the manual that comes with the aircraft, cause it is more advanced.

Hope that helps, feel free to correct me if I'm wrong.

From memory, if you use the flight planner to plan your route, the route will be automatically entered into the GPS.

press the nav button

You also have to make sure the GPS/NAV switch is set to GPS.

I knew how to use autothrottle, but I didn't realize that the knots setting was for ascent/descent and the mach was for cruising. I thought you just picked one measurement or the other  Smile

Ahh...so the GPS button will make the aircraft follow the waypoints on your flight plan. I have been unclear on the difference between the NAV/GPS settings. I haven't learned how to set up a flight plan manually yet. Right now, I just select my departure and arrival airports, use the automatic flight planner in FS, and load the flight plan it creates. Then of course, I have to adjust my HDG indicator or use the stick each time I hit a new waypoint.

Thank you so much to you both. I'll give this a whirl and see how it turns out  Smile

More corectly would be to use mach over Transition Altitude (I think), cause then there is no speed restriction. Usually, there is a 250 Knot speed restriction when you are under the TA.
And if you set a mach number under it, your air speed and ground speed will change depending on altitude (and air density, temperature and so on).
But if you set 250 knot right after takeoff, and when going through TA (18,000 feet in USA) you sett mach number to cruising speed.

Now there are som things I'm not totally sure about, so please someone correct me if I'm wrong:

Speed restriction is not restricted within TA, but in individual altitudes depending on which airport?

You Don't set mach number until you hit cruise altitude?

Actually its 250knts under 10,000 feet and unlimeted over that but then transition altitude is when you generally change from knots to mach as its more effective.

Think thats correct

Do you know wether there is a way to find VOR's, NBD's, DME's, waypoints, stuff like that.

I am currently trying to do this with a flightplan I got of VATPAC and would like to enter it into my FS GPS.

Only way I can think of is to go into MAP mode, and there you can select it to show all VOR stations.

I haven't used the GPS mode that much, but if you check out all the menus I think you can find a way to enter different waypoints between starting point and destination.

The change over from Knots to Mach and vice versa has nothing to do with the Transition Altitude/Level. With a transition altitude of 3000ft, it would be impossible to fly in Mach. It is based on efficeincy.

Eg.

On the 747 Classic, we climb at around 270kts until above FL100, then accelerate to approx 340kts. Climbing continues at this constant speed until an altitude where 340kts equals the proposed Mach number for climb, usually M0.83. (In a constant IAS climb, Mach number increases as altitude increases.) This automatic switch over occurs at around FL270 depending on the prevailing conditions.

In descent, it's the opposite. Initial descent at a constant Mach until the IAS reaches the required descent IAS, then the switch over.
