PMDG help

I bought the PMDG 737NG recently, and have been trying to figure out how to start the engines properly/set FMC, from a cold cockpit. I am using a tutorial, availabe of their site, called 737TNG Flight Tutorial (search AVSIM, it's there).

I've tried, tried and tried over and over again, and I can't seem to get the engines to start Embarassed. I followed the directions, and checked with default manual, seems like same thing. APU was on, and set properly *I think.* When I turn ignition to right (also tried both), and then turn that knob to GRD, nothing happens and the N2 power remains...err blank with 0.0 Mad.

Hmmm, that's a tough one. So you turned on the APU, turned on the APU generators (not sure if that matters, but it's good practice), and set the APU bleed to on?

If you pop one of the start levers over to GND, you should hear the engine start to spool up right away. In about 30 seconds you should be able to flip on the cutoff valve. Make sure you're not trying to start it using the Cont or Flt controls, as was my mistake when I first got the plane =). Cont is short for "continuous ignition," for takeoff/landing use. Flt is for when you're flying and need to re-start an engine.

If that's not the issue, then i'm not sure what it is. He steps you through what you need to get the plane off and running...Let us know how it goes! It could be (and nearly always is) the smallest detail!

It turned out I had the ignition valve on auto, and that closed it for some reason.

Now I ran into a new problem, once my generators are started, where should ingition be, off? When I turn the APU off, electrical power goes away (like 50 things light up again), generator pumps are on and electrical pumps are on as well but they are low pressure. Any ideas on this?

Have a look at this tutorial and see if that helps

PMDG 737NG Start up

Glad you got them started! When you start up the engines, don't forget to bring their generators on line (same way you would the APU). Even though the generator light is glowing, that doens't mean they're on line. The blue light above the switch should actually extinguish when you switch them on.

Thanks guys, I confused the generator switch with another one Embarassed.

Now if only I could figure out what the "Top left screw of the MCP" is...

TSK,

that top left screw on the MCP (the Autopilot) will activate TO/GA, or Take off / Go around mode.

When you have completed all your preparations for take off, and you have your clearance, push it, and get ready fast to fly... 😳

Yes, I found that out after I located the screw and pressed it Wink.

But I now have more questions 😕, after I rotate and have a positive climb, I retract gear and activate autopilot (the tutorial which I indicated earlier explained the steps to use to set up FMC). When I try to press LNAV and VNAV, the two don't light up and nothing happens, can't figure out why. In FMC, it now says "no active route," although one was set before take off.

You may have set the route, but that's a two step process! Very easy to forget one or the other. After programming your route, you'll see at LSK R-6 or something the words "activate"...Press that to activate the route, but to LOAD the route you have to hit the glowing "EXEC" button on the FMC right after. Then the computer should know what you're talking about.

You're making great progress, keep asking away 😀

I think that was it, thanks!

New question, where is the STD button for the barometer, I couldn't find it.

Pro Member First Officer

It's on the EFIS control panel up near the top left I think.

And now, we come to the landing:

I tried both times, using autopilot and had to do it manually (crashed once, saw a problem too late). Is the green box the glideslope indicator? What does that mean exactly, how do I tell if I am above or below it? Should my crosshair be inside that green box?

Oh, and another question. What does "airport in IFR" (or something like that) mean? Thanks.

Can anybody help me out, can't land without that information.

I'm on my way to work TSK, but will look in tonight if nobody else helps you out.

Hey sorry I missed the message. When you're following the glide slope, you're following the purple dot on the bottom and the purple dot on the side of what you were showing us. I've never actually asked the question of what that green box is! It should have it listed in the manual somewhere.

But anyway, the pink dot on the bottom shows you how far left or right of the runway you are. So you pretty much want to steer towards the dot if it starts shifting one way or the other. The pink one will show you how far off from the slope you are vertically. If the pink dot is above that middle marker, you're too low (note: you usually start out low on a glide slope, and as the pink dot descends to the middle marker you catch it on its way down). If the pink dot is below t he middle marker, you're coming in too high.

Continue asking away 😀
