.. is the NAV/GPS Switch?

Hi BA772

I don't think is needed. You probably just didn't see that the whole IRS panel is switched off. The IRS panel is needed for the autopilot. Otherwise nothing will happen. You only have to set all lower switches to NAV. You then wait until you get a few digits on the little screen, that is your heading, if your heading know is selected in the IRS panel.
I had it in the beginning aswell, just set all knobs to NAV and the upper knob to hdg.

Hope this can help.

When i want to Activate the Autopilot i cant activate VS and ALT together because when i switch on VS, ALT goes off and opposite.
And i want to once fly this Beauty!!!! And i got one Question: Do i have to fly with FMC???Becuase if i want to use an FS Flightplan i make it load already into the Aircraft, and if i can do that witch ANV would i have to select?

Is there a way to set up the autopilot to disconnect via a keypress? When I press the key I have assigned to that task (which works in all my other aircraft) I get a warning sound and a voice telling me the AP is disconnected however it is not. If I click the AP disconnect bar with the mouse, it disconnects and I hear a different warning sound. I have also observed that pressing the AP and AT buttons in the VC works exactly like it should. Would like to get those button functions to respond to a key press.

Thanks in advance,
Joe

Hello Bob,
Will check out the mentioned thread. I too assign all the AP disconnect, trim and autothrottle commands to yoke buttons. I do that thru FSUIPC, using buttons on the yoke to send key presses. I quess per your comments that is not possible on the CS 757. On my other add-on Boeings, when the AP button is pressed it causes a "soft" Ap disengage which disconnects the servos without interacting with the AP disconnect bar.  Once again thanks for your input.

Regards,
Joe Esposito

I am posting here since this IS an AUTOPILOT issue I think or is it an Approach issue?  Although I am only a simulator commercial pilot, I was able to train on Boeing 757/767 CBT through the generosity of a close friend who is a captain for a large airline.  Anyway, when pushing APP, it is my understanding that all three CMDs are to activate for a LAND3 approach.  Mine don't.  What am I doing wrong.  I have lnav pushed and runway selected in the CDU no discontinuity.  Anyone who has the answer please help me out here.  I am tired of landing my plane manually when it cound autoland. Reading the CS manuals has not helped and Boeing says they should.  PS I was under 1500 feet and on glidepath but Approach was not descending.

I've spent some hours in a CRJ sim for the same reasons you point out above.  Quite a thrill, is it not!

I assume from what you've said that the FMC controlled the descent, and brought you in proximity of the approach, if so, that rules out all FMC items except one...

I assume you selected an approach?  Or at least a runway?  The database on the FMC in CS757 is limited, even if it shows approaches and runways it doesn't always store the ILS frequencies for that runway.  Check the NAV/RAD page and see if the ILS is in there.  If it's not punch it in (like 108.70/326 for freq and course) and shift it up to the ILS location with the left side key.  Or, you can put it into the ILS radio directly, which is on the center column of the Aisle stand, below the transponder and above the rudder trim.

Once you're holding heading and altitude to intercept the ILS, and assuming you're below the slope, click in APP mode and when you start to get near the ILS, the plane should turn in, and once it's intercepted the GS, shortly before landing LAND3 will engage and all 3 CMD modes will come on.  I've had a few cases where it did not engage LAND3 until I was almost to my DH setting, and as I recall those were all rough landings because the LAND3 didn't flare soon enough.

The biggest keys here are to make sure the freq and course are in the ILS radio, and to have patience- LAND3 won't engage until you've intercepted glideslope and I believe I won't engage unless the gears and flaps are down.

Hope it helps.

I second that, and i would also add, that from what i have experienced there is one more condition to make the autoland active. You have to be fully stabilized on the GS and LOC. In certain weather conditions it might be difficult and can happen really late or even never. With mild weather 100% of my landings were in autoland mode. So unless you are flying in hurricane, you might be doing something wrong.
