Throttles not at idle on landing

[barramundilure 152]

Hi everyone I have noticed this for years and just put up with it but thought someone might know what the problem is. When I land and pull the throttles to idle there remains some residual thrust in the engines until I push the throttles forward a bit again and then back to idle.

It only happens with the PMDG B737. I have the PMDG B777 plus TFDi B717, Flight 1 Mustang, Vertex DA62 and have no issues with any other aircraft.

Barra, what is your "residual thrust", resp. which N1 value do you read? Sure you disabled A/T on manual approach(?).

Hi Pegaso, residual thrust is about 31%N1.  Yes A/T is off at around 1000' agl as is A/P.

There are different levels of idle just so you know depending on which phase of the flight you are in

As above. FADEC logic is such that in the air on approach, FLIGHT IDLE is about 31-32%%. The autothrottle will put it up to 42% quite often even when you want to slow to final speed, which is a bit annoying if you are still trying to get your final flap out and the magic 1000aal company limit is looming...

Anyway, once WOW is sensed, Ground Idle is enabled. This is more 23-25% and (always dependant on airflow through the fan).

Try just leaving them back and watching the N1 drop after landing.
