Hello. I am learning to fly PMDG 737-800 NGX using the Tutorial #1 from PMDG. After takeoff it says that plane will accelerate to 250. But it accelerates only to 230. I use To/Ga as said in the Tutorial flight from Gatwick to Schipol. Please help.

Hello,

I am learning to fly the PMDG 737-800 NGX using the PMDG manual 

Soon after takeoff at about 300 feet suddenly the speed autopilot dissapears. If says 162 , and suddenly dissapears. And after that I can not activate autopilot, although in the manual it says that at 400 feet engage CMD A and take off your hand off the controls. Please help. That is very strange.

Your conversation about the PMDG 737 and how to fly it are similar topics, whether it concerns the speeds, tutorials, raising or lowering the landing gear, top of climb, top of descent, when to activate the AP, how to program the FMC, how to use the NAV frequencies, changing the comm frequencies, etc, etc.  Hope this explains forum etiquette.

And I still have one quick question remaining about the speed disappearance. All that you told in your last message I understood but I didn’t understand the most important. The speed dissapears , but how could I then engage the autopilot. In the manual it says: passing 400 engage autopilot. But how if the speed is gone ?

An hour ago you stated you understand what I said and now you do not.

That is because the VNAV is not engaged.  When you click on VNAV, the FMC takes over the rate of climb and speed (so it removes the speed from view (see about 10:53 after he clicks on VNAV).  All gone!

This was my answer.

Best regards,

Jim

THank you . Sorry.

Hello,

i am learning to fly the PMDG 737/800 NGX. Have a question. Why is autopilot not engaging(CMD A). Does the autopilot not engage if I touch the yoke ? Or how? 

the  auto pilot  will not  engage unless  the  aircraft is  in a level flight( it  will disengage  if  you move the  yoke  as well)  and  i think  above  400  feet  all is  explained  in the  fcom    that  you  had purchased well worth   having  a  look

Yes, look at page 4.20.2 of the Flight Crew Operations Manual (FCOM) Vol. 2.  FCOM is provided with your aircraft purchase in the PMDG Ops Center.  The aircraft does not have to be in level flight though.  Just make sure you do not have your hands on the controls when you engage it (FCOM - Autopilot Engagement Criteria).  Only one AP can be engaged at a given time unless the APP is engaged.  I usually engage it soon after raising the gear and the aircraft appears to be stable.  There's really no regulation that states when the AP is engaged after you takeoff.

There are two options in the NXG FMC for the autopilot to connect. One of them is that for autopilot to engage you must have the aircraft trimmed properly for the autopilot to engage (realistic option). The other option is to be able to engage the autopilot with the plane out of trim (not realistic but easier). 

Having said that, I’d assume that you’ve got the first option selected in the FMC options to have the autopilot engaged when the aircraft is properly trimmed which is why you been told to have you hands off the controls. However, if the aircraft is properly trimmed you can have your hands on the controls and it will still engage.

If you want to set it to the other option to engage while the airplane is out of trim you will have to go into the FMC options/setup pages and change that. Off the top of my head I can’t remember which page in the FMC it’s on, but it’s covered in the PMDG Intro Guide as to where that option is located.

This has been brought up many times in the PMDG forum where people were having issues getting the autopilot to engage and the setting of those two options and the plane being out of trim were usually the reason why.

Btw, Avsim has a PMDG 737NGX forum. The section is located here -> https://www.avsim.com/forums/forum/432-pmdg-737ngx/

It might be worth reading through their forum to help get you up to speed.

Hello,

I am learning to fly the PMDG 737-800 NGX. What do the IRS switches do? What do the fuel pumps , l pack and r pack do? 

Best advice is that you do the tutorial flight. All of your new user questions and more will be answered. Most of us here in the forum cut our NGX teeth by flying the tutorial at least once.

Oleg, I merged your newest NGX question into this topic since the title of the topic title encompasses all your questions related to the NGX.

best bet is  to read the  fcom  on the  sections  your  having  issues  with, is  the only way  to learn
