Describe the bug

when all set (passengers on board, flight plan included, etc.) one will need to enter details in MCDU / PERF / TAKE OFF RWY xx. All buttons (LSK1L-LSK6L and LSK1R-LSK6R) work except LSK1L-LSK2L-LSK3L to insert the V1, VR and V2. I can push whatever I like but I will never get a calculated V1, Vr and V2 speed based on the figures already available in the MCDU (Fuel/Payload/etc.)

The same buttons LSK1L-LSK2L-LSK3L do work correctly while in MCDU / PERF / APPR to insert QNH, TEMP and MAG+WIND !

Hence I assume a bit or byte has dropped out in the TAKE OFF RWY xx page.

Expected behavior

I expect to get the calculated V1, Vr and V2 speeds shown to be inserted.

Steps to reproduce

1. As mentioned above

Is your flaps setting inserted?

Yes, I insert "1"

By the way, when flying with FBW A32NX MCDU is working perfectly. Hence all buttons work correctly.

A bit more information. After Flightplan fullfilled, ZFW/Fuel via LSK1R and LSK3R fullfilled, going to TAKE OFF page.

1. inserted 1 at flaps
2. inserted 50 at Flex
3. checked/insert Trans Altitude via LSK4L
4. then pushed in LSK1L in order to get the normally calculated V1 speed on bottom line (which does not appear), hence V1 remains empty
5. then pushed in LSK2L in order to get the normally calculated Vr speed on bottom line (which does not appear), hence Vr remains empty
6. then pushed in LSK3L in order to get the normally calculated V2 speed on bottom line (which does not appear), hence V2 remains empty

Going to APPR page - LSK1L to insert QNH, LSK2L to insert Temp, LSK3L to insert Wind info. On this page these buttons operate correctly.

By the way in TAKE OFF page when inserting on bottomline a speed figure and then push on LSK1L than the information will be inserted, Same goes for LSK2L and LSK3L.

My conclusion : the calculated speeds by the system does not take place when pushing the LSK1L for V1, LSK2L for Vr and LSK3L for V2.

Hope this will give you some more thoughts.

@st3ph29 : unfortunately I am still grounded. I changed to FBW A32NX u.f.n.. Any progress ?

[YoLo1956]

UPDATE 25 October 11:00 hrs : today after update DEV to 6d39c05 I jumped again in the cockpit and did the same steps again as mentioned above. Result : no change ! Then decided to leave V1, Vr and V2 blank and start engine 2. When engine 2 was stable I went back to MCDU / PERF / TAKE OFF page and simply pushed the same LSK1L a few times ....... AND then suddenly the V1 appeared. After this insertion I did the same with LSK2L and LSK3L to get Vr and V2. Please note before starting engine 2 I pushed in MCDU / PERF / TAKE OFF page the buttons a numerous of times with no result. My conclusion : getting V1, Vr and V2 has to be established in the MCDU / PERF / TAKE OFF page before starting any engine, but it does not act as such. This program section has possibly to be advanced (I have no in-depth knowledge of programming).

I hope this will provide you some additional feedback to solve the issue once and for all.

NOTE : I have decided to do a full reinstall of MSFS 2020 2 days ago hence a new clean version.

We couldn't replicate this behaviour, additional feedback is needed.

I managed to replicate something similar. It isn't really what @YoLo1956 described but as I said, something similiar.
