Hi all, I know it starts to get boring but I just want to start with a big compliment to the PMDG team! Thank you very much for this masterpiece! Now on topic: I never managed to fly a proper automatic go around. I'm following the Boeing procedures but still the aircraft is not behaving like it should. It would be great if someone can check this procedure out for me and report back his/hers findings. This is what I do: Fly a standard ILS approach with both CMD's on (flare mode will be armed indicating it is ready for a automatic landing or go around). At minimums push the TO/GA switch and select flaps 15. When positive select gear up. Now, normally it should pitch up for a steady climb with about 2000'/min. But in my case every time I tried it, it reduces power right away and doesn't climb at all. The airspeed then starts to drop of quickly and I have to take manual control to save the aircraft. I tried this procedure with joystick and without joystick, with ASE and without ASE, it made no difference. I'm very interested if this has something to do with my setup or not. Thank you for trying! Best regards, Daniel Verhaal

Somebody? I really want the automatic go around mode want to work, so I hope it has something to do with my system.

Do you have missed approach altitude on the MCP?Something that I have noticed and, without any doubt is accurate, is that if your throttle levers are not within a very close percentage with each other, the AutoThrottle will kick off. If you push TO/GA and your throttles are not close to even, there is a chance that the A/T kick off and TO/GA won't work.

Hi Robert, Yes, I have set the missed approach altitude and the A/T stays on as it should but it just throttles back immediately. It does not climb at all. I just tested it with a fresh install of the NGX and with the default 738 with the fail operational option. Made no difference, still a very strange behaviour. Have you been able to perform a automatic go around with the NGX? Daniel Verhaal

Never heard of automatic go-arounds, in Boeing, Airbuses or any other western made aircraft.Actually pressing the TO/GA should among other things disconnect autopilot and give you pitch command on FD. But it is pilot hands that must establish the desired pitch. Re-engagement of autopilot comes later.I think you better study the manuals, this is absolutely basic knowledge. But check with Boeing pilots here on this forum too, no doubt during beta testing they preformed hundreds of go-arounds.

Hey on the NG if you're flying a dual channel approach the autopilot will remain on during go-around. If only a single channel the autopilot will disconnect.Cam

Hi Michal. On a dual autopilot approach on the Ng, the autopilot remains engaged and flies it for you. The only thing you need to do is bring up the flaps.Lol Cam. We must have been typing at same time

Nope nothing wrong with your system All is correct. The reduced thrust limit (GA mode) that you see there is one calculated that in the end at clean speed the plane will climb at a specific gradient (which translates to around 1000 to 2000 fpm). Second push of the TOGA switch and you go full thrust. I had exactly the same question with you when this thing was developed and asked our tech advisors for additional confirmation. PS. Useless information : the calculated speeds that you see on GA are all based on max gross weight (regardless of your actual gross weight).

I read the Flight Operations manual and practiced many Go-Arounds on Dual CMD and the same thing happens to me as the OP stated. I just expect it to maintain GA thrust and maintain MCP or whatever speed for pitch up to MCP Altittude. I understand double push gives you actual GA thrust so can someone explain the exact logic of what the plane does when GA is pushed once. Thanks

I hope they will look into this again because it really doesn't make sense. The go/around mode should give you a v/s between 1000-2000 fpm. Now I'm just hoovering above the runway with a vs of barely 50 fpm with airspeed bleeding off. Very dangerous in real life. From the manuals: "A/P Go-AroundThe A/P GA mode requires dual A/P operation and is available after FLARE armed is annunciated and prior to the A/P sensing touchdown. With the first push of either TO/GA switch:- A/T (if armed) engages in GA and the A/T Engaged Mode annunciation on the FMA indicates GA- thrust advances towards the reduced go-around N1 to produce 1000 to 2000 fpm rate of climb- etc...."

I think the AT is reducing thrust because full trust it is not required to produce 1000 to 2000 fpm. Then if you push it again you will have full trust and climb at more than that fpm.

Hi Matias, I know the AT should provide reduced G/A thrust after the first press of the TOGA switch. But it should give you aprox. 1000-2000 fpm of climb with a pitch of about 15 degrees. The problem is that this is not happening at all. It barely climbs and it is losing speed fast. Please try this procedure in the NGX and you'll see what I mean. Daniel Verhaal

Yes, I'm sorry, i should do that.

Not useless - they are the highest figures therefore giving the greatest stall margin. Best regards,Robin.

Just did a few Go Arounds , you are right .GA Mode seems weired.LAND3 Approach with both flight directors on..push TOGA switch in 300ft.It goes to GA Thrust and Pitch Up but after a few Seconds it reduces thrust to70% N1 and the plane hold level and no climbing. After clicking TOGA buttonagain it Pitch up and gives thrust.
