Same in Norway, no problem as long as you don't vector from the TWR position if you have any other tasks/traffic.
But...in Norway (and Sweden, if nothing has changed in the last 3 years), all ATC units have CAS (CTR&TMA) that give IFR traffic the ability to fly from a controlled to a controlled airport without leaving class D/C (Even the ones without pressurized cabins)
We don't have the RIS/RAS in class G to contend with. The fact that there is a requirement to carry a working SSR in CAS allso helps. (No PSR tracks to babysit)
And frankly, the old matra that radar is not helpful when working TWR only, is ridiculous. (Sure, the Mk.1 eyball is still the most important, but everything that increases SA is good in my opinion)
(Give me a hint to where you work MSI, I might know you!
