pmdg 737-800 spd rest problem

Recommended Posts

Hi I`ve been flying the PMDG 737 600 for a while now and thought i`d give the 800/900 Ng`s a try.Downloaded them a few days ago but i`ve found i`m stalling and falling out of the sky soon after take off. Even though i`m sure i`ve programmed the FMC correctly. My speed tape shows red boxes throughout the speed scale and for some strange reason the SPD/REST shows zero in my FMC on my initial climb. I`ve googled this problem and found others to have had the same trouble with the 800/900 but i couldn`t find a solution.i`m taking off with a flap 5 setting and I`m sure i have all my FMC and MCP settings correct. Any help ???????????????

Doesn't sound like the auto throttle is engaged. Could you provide a screen shot?

hi I have the auto throttle on and use ToGa to set N1. After takeoff i`m engaging LNAV and VNAV. My speed tape then turns red - SPD REST goes to zero knots and i start to stall. I`ve come across another post on the forums that also discuss this problem and it suggests i remove all my PMDG files and re-install them.The post is here http://forums1.avsim.net/index.php?showtop...hl=737+airspeed Sorry to sound a bit dumb but if i remove all my pmdg files how do i re-install them?? And will this actually solve the problem??

Paul wasn't referring to uninstalling the installation files, just ensuring that all of the PMDG files are removed from the FS directory. :( Before you uninstall/reinstall, sounds like there is some corruption somewhere. Are you starting with a custom startup rather than the default?

ok I`ve been loading the flightplan into the FS9 start page ( Dept. Gate, weather etc) and then loading the game using the default cessna - closing down the cessna engines and then swapping the plane to the PMDG 800NG. so as to enable a cold and dark cockpit. The only way i know how to begin in cold and dark. I tried it again tonight and notice as soon as i set the flaps to 5 the SPD REST turns from 250/10000 to 0 FLAPS. Speed on the PFD goes to zero as soon as autopilot is engaged. I`d add a few pics but i don`t know how to do it sorry

737 speed restriction problem with red bricks in the wrong place on the speed tape is a guage.ini (or cfg) problem. It comes up every couple months here. The various speed restrictions for configuration are supposed to be in this file and if missing or corrupt this is the problem you see. Deleting all pmdg files before reinstalling should help, there is a 737 removal tool available at the pmdg website.

ok cheers for the reply. I can only find a removal tool for the 737 800/900 though. Will running this do the job or do i need to remove the 600/700 aswell?

I don't know... the goal is to update the guages.ini file... did you check if there is a repair option in the installer? I'm not at my own workstation where I can check these things.

Yes i`ve run the repair option for both the 600/700 and 800/900NG and it`s made no difference.

Okay, check file 737guages.ini and see if it has the following section:

[PFD]VLE=270.0FlapPositions=9// Default Values (for 700 too)VMaxFlaps=340.0, 250.0, 250.0, 250.0, 210.0, 195.0, 170.0, 165.0, 156.0//Specific values for -600VMaxFlaps_600=340.0, 250.0, 250.0, 250.0, 210.0, 185.0, 175.0, 160.0, 155.0//Specific values for -700VMaxFlaps_700=340.0, 250.0, 250.0, 250.0, 210.0, 195.0, 170.0, 165.0, 156.0

This is the data used for flap speed restrictions. Hope it helps.

yep this is a copy & Paste of mine [PFD]VLE=270.0FlapPositions=9// Default Values (for 700 too)VMaxFlaps=340.0, 250.0, 250.0, 250.0, 210.0, 195.0, 170.0, 165.0, 156.0//Specific values for -600VMaxFlaps_600=340.0, 250.0, 250.0, 250.0, 210.0, 185.0, 175.0, 160.0, 155.0//Specific values for -700VMaxFlaps_700=340.0, 250.0, 250.0, 250.0, 210.0, 195.0, 170.0, 165.0, 156.0Identical. Tonight i ran the removal tool and that didn`t help so i completely removed FS9 from my system. Deleted all the files in programme files/microsoft games and started all over again from scratch and it`s still doing it! i don`t know what else i can do

Yipes... that was pretty drastic. If you are using Vista, make sure that the pmdg folders and subfolders have admin rights assigned when doing install. Next, send email to support at pmdg and explain the problem. If we have ruled out the guage file then it is something that I haven't seen in the forum yet (that alone is not big news tho.. sorry). Make sure you get an automated response from support. No response = they didn't get your message (some have to use gmail depending on isp). Frustrated? Hang in there.. we are amatures in the forum, time for the expert.PS Please post the fix once you find it. Thanks.

Ok thanks for your replies anyway. I`m using windows XP. I`m going to try a few things before i E-mail PMDG.I wanna see if this is happening to the 600/700 aswell or just the 800 and will also load up the aircraft without starting in cold and dark cos i`m sure this problem only started after i started loading up this aircraft in this way. I`ll keep you posted as to what the problem was --- assuming i ever find out.Also can you tell me what the `` A `` is next to the speed on the MCP.I have 166knots set on the MCP speed for takeoff which is V2+10 knots. When i engage autopilot after takeoff the speed on the PFD shows zero and i get an `` A`` next to my speed on the MCP.Also i`ve noticed sometimes i get an `A` after an altitude setting in the FMC when i havn`t set my altitudes in the FMC yet. What does the ` A` stand for??Cheers

AOM pg 7-16: The A character means it thinks commanded speed cannot be reached, most likely due to original problem you are having the speed restrictions. I recommend you email support.

ok Update: It makes no difference how i load the 800/900 aircraft i still get the same problem.The 600/700 series however seems fine and flies without a problem. Upon selecting flaps the SPD REST shows the correct and relevant speeds -- Unlike the 800/900. I`ve noticed that the Guages.ini file that we looked into only refers to the 600/700 and i can see no reference in that file to the 800/900 which leads me to believe that there is a seperate guages.ini file for the 800/900 though i can`t find another guages.ini file anywhere on my system.I`m going to E-mail PMDG now and show them this forum post. I`ll post any reply i get on here.

Yeah, I suspect (I'm guessing) the 800/900 might use the first line for default values or those values are calculated by the FMS with the newer program. Anyway, I also do not have separate 800/900 ini files so you can assume you are not missing those.

ok cool so i know i`m not missing some complete guage commands. Anyway i E-mailed PMDG tonight and recieved an immediate auto reply so fingers crossed i can suss the problem soon,post the solution and put the problem to rest.Few more questions i have ... Bare in mind i`m fairly new to flight sim and it`s a rapid learning curve for me ATM and i`m a flight sim enthusiast not a computer programmer.I downloaded a few Afcad files months ago and found afterwards that i`d lost all my taxiway and runway direction signs. ( you know the red and yellow direction signs on the taxiways)Well when i deleted all my FS9,PMDG,AI files,Afcad files the other night and did a complete re-build i was thinking it might also solve this problem too but i`ve found i`m still missing my taxi signs. I only installed the FS9 programme with PMDG this time Mmmm!! What happened to my Taxiway signs i wonder?????? Also on the 737 can anyone explain to me what determines the vertical climb or decent rate when using the FLCH button or VNAV. It seems the only way i can control the aircrafts climb or decent rate is to use the V/S. It seems sometimes when i fly a FLCH or VNAV climb for example the aircraft can pitch nose upward to say 3500ft/min and other times only say 900ft/min regardless of the amount of nautical miles before my next waypoint.Hope you understand what i`m tryin to askAll very confusing but i`m getting there!!Had a very enjoyable flight tonight to EIDW RW16 and finding i don`t tend to crash these birds anymore. X-cept when i try to fly the 800!! Grrrrrr!!

You should start a new thread on new topics... that will help with responses from the other guys in the forum.Descent rate is usually not a controlled flight variable, in climbs you are interested primarily in IAS whereas in descent you are interested in altitude constraints.

Is your autothottle armed? If you don't turn on the generators after engine start the A/T won't "catch".

Yes the Autothrottles are on. This isn`t a problem with the autothrottles /Overhead panel settings/MCP settings etc. I do exactly the same in the 600/700 737 with no problems. The only difference is when i deploy the flaps in the 800 or 900 i notice the speed in the climb page switches to zero whereas in the 600/700 .......... upon deploying flaps 5 it goes to 245knots and then the speed goes down in stages to about 190 on flaps 25 ( from memory) On the 800/900 it just switches to zero even on flaps 1. It makes the aircraft impossible to fly

Did you ever get this resolved?I'm having the same issue. Re-installing didn't solve anything.

There is a configuration file in the pmdg folder that the 737 uses for setting up the various flap speeds (ah, found it '737guages.ini') If your nanny-security features of the operating system do not allow the update installer to modify this file then you will get the results you see. Run the installer as admin, consider turning off the UAC, and assign admin rights to the pmdg folder and subfolders.

Thank you Dan, much appreciated for this response.I was having the same issues under Windows 7, with the retracting of flaps, zero in the red tape and finally a stall while taking off in the 800/900. The 600/700 series worked great.I removed all versions of the 737, turned off UAC, reinstalled all files and updates as administrator and all the problems went away.Thank you very much again.Chris Bremmer
