PMDG 18 second initialization and SLEW mode

Recommended Posts

I've been practicing the Roaring Fork Visual Rnwy 15 at KASE ... did the usual trick of saving the flight through FSX and then reloading ... PMDG is great about reinitializing ... anyway ... after loading the flight I have to wait 18 seconds for the plane to start back up.  By that time I'm down 300 to 400 ft. ... I lucked into a solution.  Most of you probably know this trick ... but I found that if I press "Y" ... or slew mode ... everything freezes ... the countdown ends ... I press Y again to get out of slew mode ... and my plane is up and running ready for another go at a challenging visual approach.

 

Just thought others might get some use out of this information.

Interesting, I wonder if everything actually initializes correctly. I usually save about 3 or 4 minutes before touchdown for this reason.

The 777 in to KASE?  I'd say go for whatever works for you because a 777 in to KASE is never going to be realistic.  A 737NG would be a heck of a big plane in there.  More on the order or CRJ's and  turboprops.

I did a MLW 777 into NZHN Hamilton airport, that's about a 6000ft runway. occasionally sees 737s and A320s. Autobrakes MAX however. Got to love the red glow huh!!

The problem is usually not the landing!

You can take the 777 to a full stop on a surpisingly short strip.

 

It is when you have to depart from there again, that the problems start.

(not an FSX problem haha)

 

Like these guys in November:

Nope, I did not know that, good tip!

 

Thx.

For what it's worth, there is specific instruction in the intro manual to leave the plane alone until it is fully initialized.

 

I'm wary of any "trick" that circumvents a normal initialization status indicator.  Perhaps that's just the real world flight side of me, but if I did something that made an initialization status indicator instantly jump to "ready" when it normally takes longer, I would assume something didn't initialize properly.

 

That's just me, though...

I agree with Kyle.

 

I just wrote a long piece about CTD and that one should try to prevent it from happening.

 

Who knows, this might just be one of those things that cause a CDT after the 10th time or so.

 

I am going to refrain from using it an will accept the 300ft altitude loss.

 

Sorry Charles.

I could have mis-read it, though.  He could be saying that slew is simply being used as a sim pause mode where the aircraft isn't allowed to move while the countdown continues.  If so, then that's actually a pretty smart trick.  How I originally read it, though, was that it was a way to sidestep the counter and set the aircraft up to be immediately ready.

I read it as using slew as a freeze. Slew mode won't bypass the initialisation countdown. The big problem with using slew for this is if you accidentally touch the controls and do move the position or heading. Slew is quite sensitive so you could be miles out of position before you know it. So why not just use pause (P)? That's what it's there for. I'm fairly sure the PMDG initialisation would still continue.

Actually it does not... I believe that pause suspends processing of gauge code, so that makes initialisation stop as well.

Well that shows the difference between being fairly sure and being right! I thought I'd seen it continue, but you're right - it doesn't.

Easiest is just don't save quite so close to landing. As I said before, a few minutes out might be a better idea.

I use this trick when recovering from the ever-present OOM. It beats 20 seconds of in-flight free fall after loading while the aircraft initializes. Just drop into slew, wait for the T7 to do what it's gotta do, then unslew and off you go.

 

As others noted, pause suspends the update loop on the gauges so nothing progresses. Slew provides a running but motionless sim which is ideal for this scenario.

Or the missed approach...at least at KASE, that's a pretty darn narrow valley to make that turn in.  Similar issue at LOWI.  The bigger aicraft can make the climb performance and stop on the runway, but they can't make the turn radius down in the valley.

I will try the slew trick. Gotta be carefull though as one bump of the controls and your suddenly doing Mach 42 and on the other side of the country.

Yes ... pause doesn't work ... Y (slew) does ... I'm sorry ... I didn't realize I was in the 777 forum <s>  ... I'm using the 737-800 to do this visual approach.  The turn radius is just fine ... but the descent is steep ... hard to keep her at Vref prior to threshold.  The scenery, on the other hand is fantastic!  I'm using FTX Global and the mountains are breath-taking.

 

On another note, I had to do a check ride with my VA ... it was the Parkway Visual for 13L at JFK ... that approach is very fun as well if you haven't tried it ... here is a link to the real thing ...

To make it totally realistic download the trial version of JFK from FSDreamTeam ... it gives you five minutes of time ... which is just enough to get the bird down and enjoy all of the great graphics.

Hehe, I had to practice that SOB for a while and do a fair number of approaches before I submitted the pirep...and even then, my first one was rejected because I was too high at the threshold.

Finally nailed it though   :good:

For me the third time was the charm ... first time the descent rate was over 400 fpm ... the second time I landed more than 4,000 ft. from the threshold ... then, after adopting a tip from Tabs (of PMDG fame) I nailed it as well.

 

Always looking for great visual approaches to work with ... LOWI is next.

Press CTRL + K to disable all the controllers, then press Y to enter Slew mode, now there is no possibility of your joystick or pedals sending you half way across the country by you bumping your sticks. Reverse the above when coming back out of slew mode.

I have 2 pc's both doing same, loads saved panel state, but inits the countdown evry time, even if already in the air????

 

Bob,

 

Our aircraft are a very, very complex system of things that need to be configured correctly for things to work properly. If all of this was a basic, default sim function, then I don't think our countdown would be necessary. The fact is, though, that we're asking a sim to do more than it was built to do, which requires us to run the initialization function any time our aircraft is loaded to ensure everything is set properly.

 

I'm sorry you see this as a terrible inconvenience, but I think hitting the 'Y' key and sitting in slew mode for a few seconds after reloading a flight isn't too much to ask.

I will gladly use the Y key...

 

Maybe I should read the history in this thread but I'm not; I've loaded a 777 trip while enroute on almost every trip and have never had to use the slew.  However, I am careful when I save to the flight to ensure the aircraft is not in a position that makes the  load/initialization  process difficult.  For example, do not save/load a flight that is within a couple of minutes of the next fix and if you are close to a fix it helps to save in HDG SEL mode rather than LNAV. 

 

There's no need to do anything hoky-poky if you choose the place to save with the load process in mind.

One more thing I can't let go for the assistance of potential and new 777 buyers...

 

All of the great documentation for this beauty and NO WHERE does it say that this initialization can cause a free fall in flight when you reload a saved mid flight flight and the method  (slew key "Y") to prevent it. 

 

So, if it is so well known, why are there so many posts on internet about it wasting tons of customer's time trying to figure it out because prior pmdg aircraft did not do this... so one would think this is not correct.

 

Just my two cents.

 

Still VERY HAPPY with this purchase...

No need to overdramatise. The sim won't free fall if you don't use the slew mode. There only might be a problem if your saved flight was not in level flight and/or you were close to terrain. The slew key trick was mentioned here because the thread starter found it worked for them when they made a save on approach and they wanted to share that discovery.

 

I don't know what you mean about this being so well known and so many posts about it. There are lots posts about OOMs and using flight save to recover from that of course, but few that I've noticed about problems caused by the initialisation phase. There is no widespread demand for a solution which PMDG need to document.

 

I suggest you re-read the opening post to understand the context of this thread before getting worried about something you think PMDG has missed.
