PMDG 737 Discussion (PC Version) (Part 1)

PMDG and Fenix is nothing for the casuals.
Lovely this 737-600, the smallest Boeing ever made :smiley: maybe there will be a different cockpit than in the 737-700, not only the air conditioning panel - but I don´t think so.

We will see what the 737-600 will have to offer, maybe there will be some surprises.

Not quite sure why PMDG feel the need for the subtle and not-so-subtle digs at Asobo all the time. This has been a feature of their communication over many months, and does them no favours in my opinion. Not defending Asobo in any way, and I’ve no clue as to whether PMDG’s comments are accurate, but this just feels petty and unprofessional to me.

Also interesting at the hint that the pricing of the 600 will be lower than previously billed.

Although I’m loving the 737-700 (and the Fenix A320 - they are different in good ways) I doubt I will buy any further variants as I’m not sure there is enough of a difference, for me, in what I would be paying for.

  1. What criteria must be met in order to get auto-retard upon landing? It’s not autoland only. Flying the last bit manually after a RNAV approach didn’t do it. Does it have to be an ILS approach with the frequency set in both radios?
    There is a high idle setting in the menu but i guess that’s just a little higher thrust after auto-retard to make go-arounds easier.

  2. Can i force the decel mode (speed select via flaps) somewhere? It seems we always have to hit that waypoint to make it happen, wonder if there is a button or so to force it like in an Airbus.

  1. It must be ILS, frequency on both radios, course set on both sides, both AP channels engaged.

Thank you so much, I genuinely appreciate the answer. I intend to fly AA routes that I’ve flown in real life, which they fly with the 800 or the MAX, which is why I’ve had my eye on the 800. I was also concerned that perhaps the 700 had somewhat dated avionics compared to the 800.

The 700 has perfect avionics screens in there :slight_smile:

And that´s why these variants (the same goes for the Fenix Airbus, when an A321, A319, and more are released) should be made different to keep them interesting.
Having the difference only in “one flies Mach 0,84 and the biggest and most modern one flies Mach 0,86 because of the winglets” (and no other differences at all in cockpit: avionics, cockpit layout, instruments, cockpit panel layout, and even all cockpit textures EXACTLY the same in all variants no matter if Airbus A319 or A321 or Boeing 737-600 or 737-900 are chosen in the menu) will make people somehow unmotivated to buy any of the aircraft variants.

But bringing for example an older 737-600 EIS cockpit for one of the PMDG 737 variants - yess!!! :smiley: AWESOME!
Adding some EIS into the cockpit to check the turbine status in some for the nineties ultra-techy way in the older smaller 737 variants would break the ice for many indecisive buyers :wink:

  1. In the 737 we only use autothrottle during manual flight during take off and climb. During all other phases of flight the autothrottle must be disconnected when the autopilot is not being used.
    This is not a 777. There’s no retard function unless you’re flying a dual channel approach (known in other types as autoland). Even during an autoland you must disconnect Autopilot and Autothrottle on airplane touchdown. Fail Passive airplanes do not provide control on the runway.

  2. If you’re in VNAV PTH, you can change the speed in the DES page or you can press SPD INTV to select a new speed in the MCP. If the airplane is “on approach” logic, pressing SPD INTV will not take it out of VNAV PTH. We use SPD INT during non precision approaches flown in VNAV. Normally we don’t let VNAV set speeds on final approach so we set up the legs page to fly UP speed before turning final and when we select the first flap setting, we press SPD INT and but the speed to standard approach speeds (Like 180 until 8 or as per ATC) or to the flap manoeuvre speed.

On the current version of VNAV (called COMMON VNAV) in any phase of descent, if you’re in VNAV PTH, pressing SPD INT will not change the mode to VNAV SPD. The NGX is based on the older VNAV version (Called BASIC VNAV) that I’m sure many airlines still use. With this version, if you’re in VNAV PTH and not on “on approach” logic, pressing SPD INTV will change the mode to VNAV SPEED, which is effectively like a LVL CHG that will respect the altitude restrictions set in the LEGS page.

The company I fly for has like 450 units of -800s and -MAXs and 1 single -700 used only for training (base training), VIP flights and rarely as a backup airplane.
It is fitted with a few toys needed for VIP ops but it’s still an NG. We do recurrent training on it although I have only flown it once in 5 years (the day I got type rated on the NG).
From a real world perspective it’s different enough and requires study. It has different limitations, different systems in some areas and so it has different QRH checklists and abnormals. If you’re not going in depth like a IRL pilot would, you would really not experience it differently than any other NG. If you’re the kind of simmer who uses the sim like someone would make model trains which have to look exactly like their real world counterparts and you want to fly real world routes with the same airplane, then I guess you’ll like having the variants you need. If not, it’s just an NG. I simply need the 800 because I use it to practice some things before my recurrent simulator IRL and air systems are an important part of any 737 (As it’s the part of the airplane trying to kill you every day).

Thx for detailed answer. Was just wondering why the plane stalls itself, dunno if there is a stall protection at cruise alt which adds thrust at a certain point, cuz the speed margin at altitude is thin. I didn’t let it come to a stall cuz i got back in time from said phone call. Imagine both pilots are unconcious and fail to enter a lower mcp alt in cruise close to descent and the throttles roll back to idle because they anticipate an idle descent. Wouldn’t it be safer to keep “cruising” at alt and speed until a deliberate decision is made by either pilot? Gonna test it again to see if there is a stall protection or not.

Look in your cruise page. Don’t climb higher than the Maximum Altitude it shows there. It is safe to fly exactly at the maximum level listed there, but on turbulent days it’s not “fun” as the pilots have to spend the whole cruise looking at the airspeed and ready to use speedbrakes or push the thrust levers in case there’s a gust. The autothrottle on Boeing airplanes is very lazy. The thrust levers will not be chasing the speed during cruise for every small change. A way to update the tables is to press SPD INTV and select a different speed for a few seconds. When the Thrust levers start moving it means that the ATFDS system has recalculated thrust settings based on current conditions. Then you can press SPD INTV again to close the window. Lazy lazy autothrottle…
Some airlines will set the N1 Limit to CONT during the cruise just so that the engines have better capacity to counteract a sudden loss of airspeed due to a change in wind or temperature.

If the airplane is stalling on normal flight, you’re doing something wrong.

Guess there is some misunderstanding going on here. Just be in VNAV/LNAV (of course autopilot and autothrust on) towards a destination of your choice but don’t select a lower altitude before descent, keep it at whatever it was, maybe 35000 feet or so, and watch what happens when the plane reaches the T/D marker.

I know this is not you saying this, but I really do not know what people expect? It is a 737NG and no matter what they are all the same. In all honesty be it the 737/A320-19-21/A340/A350 a C172 or 747/777/787 I have and have had them all before in different sims. Nothing has changed much, (I am talking study or 90% Study level planes here) and they are not going to. Me buying the Fenix or the 737 and expecting them to be different to say the ZIBO 737 or past PMDG products or the Fenix to be any different to the A320’s I had from PSS in FS2000/4 or the Toiis buses now is rather silly. The planes have not changed since the 1980’s what can I possibly expect different about the planes what more can they do? before it starts getting fictional?, Its a silly idea.

What is or can be different is the EFB and the quality of life stuff maybe, better more modern Simbrief integration which we have with Fenix FBW etc. As for the planes they still operate in the same way, and if they were already Study level or accepted as such what more can dev’s do.

Flying the Fenix to me is no different to flying the Toliss or Flight Factor A320, there isn’t anything more or less in the actual operation of the plane and why should there be? The only difference being is the Fenix has a way better efb, in X-Plane I would have to use more tools using menu’s in the sim to set up the plane, MSFS seems to have overcome this flaw. I mean we could argue ad nauseam over which has best Flight Model, but in terms of offering more what could that be, above what was already seen as the best in previous sims when using PMDG as an example?

What is very different and simply cant be beaten at all, is the MSFS Scenery and graphics and there is a lot to be said for that only when the plane is as good, and we are now getting these planes in spades.

Well study level means you can have a flight instructor in the right seat monitoring your actions when he pulls a circuit breaker.

Hello!

Am i alone to have all the switches, buttons, yoke and throttle totally freeze? It is actually not possible to have any kind of intercation with the cockpit for push, turn, pull etc…

All are freeze when i click on them. So i really can not to fly the Boeing 737 and it is a bit frustrating ahahah

(Just the yoke and the primary controls and throttle stay freeze but have effect on the plane. For exemple, if i turn my honeycomb yoke to the right the plane go to the right. But the yoke and the ailerons stay freeze.
Even the fan of the plane are freeze when the noise are making indication of TOGA mode)

Already deleted the plane and instal it again, i checked about the mouse option an was set for MSFS.

I already do a post on PMDG forum, but i do not have a really
answer about it :slight_smile:

That shouldn’t happen. You must be doing something wrong. If the airplane is in VNAV PTH on a cruise and you don’t start descending at the TOD or earlier, the airplane will initiate a mode called “Energy Compensation”. It’ll slow down but it will not stall!

When this happens, the AFDS will select a slower speed while keeping the Target Speed constant (Econ dictated by your Cost Index or the pilot selected speed for descent, for example .78/280). This way, when the crew are allowed to descent, there’s an acceleration margin to burn some potential energy into kinetic energy and catch the descent. It’s all about energy management. If this acceleration is not enough to catch the descent, the message “drag required” will be shown. This doesn’t mean that speedbrakes are required. In this case you can simply select a slightly higher speed for descent which will result in a steeper descent that is easier to catch when you’re high on the original speed path.

Ok, so it won’t stall, that’s reassuring.

Totally agree! I find it annoying and quite unprofessional.

The sim without addons is nothing. The addons without the sim are nothing. It shouldn’t feel like the addons developers are piggybacking from Asobo. They should be working together, so when a developer as important (the most important) as PMDG needs a certain collaboration from Asobo to bring some real world airplane characteristic to the simulated world, Asobo should either collaborate or provide an alternate way of solving the problem. When it comes to complex simulated versions of real airplanes, I’d assume there aren’t many companies with as much know-how as PMDG so if their development team consider that a certain technical feature is necessary (debugging tools), chances are they are right.

But yeah, I know what you mean when you say this shouldn’t be vented in public forums. It just happens that PMDG was as active in their development as it is now even when the flight sim community was a lot smaller than it is now. The PMDG forums were a more private intimate place than they are now and it really felt like it was just RSR and a bunch of us talking in private. Flightsimulator forum just didn’t exist. Maybe they’ll need to adapt to the fact that simulation has now become more mainstream than it was.
