Fluctuation of speed

Featured Replies

Hello

 

I hope i write the word correctly but my speeds are going up/down in flt.

Than i have overspeed with m.78 and then it's going down to m.65 .

Anyone a clue?

due to the wind coming from front or back side.It will reduce the round speed accordingly.

ground speed or IAS

FSX default real-world weather possesses wind bugs, which cause rapid and often repetitive wind shifts, thus creating ticking sounds and/or unrealistically large speed changes. Wind bugs can be resolved by using an add-on weather program or FSUIPC wind smoothing.

thx for the answers indeed it's the wind head/tail

sorry guys it's still the same look at picture it's not clear but it goes up and down.

I put on smooth in the wind section of FSUIPC.

I climb with a desent 2000ft/min which i think for a B&* is not to steep,but then my speed drops dramatically and i have to climb in steps.

Hello

 

Sorry i thought it was solved but it still goes up/down like hell.

I climb with 2000ft/min i don't think that is to steep for a B738.

I put on smooth in the winds section of FSUIPC.

Hi Frans,

I presume you have a registered copy of FSUIPC? Maybe as a test,you could select wind calming and the other three boxes as well:

Turbulence, Gusts, and variance. This should take out all winds and gusts.

Have you prepared a flight plan in the FMC so that LNAV and VNAV are working ok? This should take care of climb/cruise speeds and altitudes.

 

Regards
