" professionals " .
There is no problem with switching from vfr to ifr if you have it as a planned option .... It's quite normal !!
Sorry to ruin your day but you may not have realised ...... The idiotic ppl brigade already swim in your waters .... And have done , virtually incident free , for quite some years . It's called an "IMC" rating and is basically the same as an EIR I guess .
Anyway don't panic , the idiot helicopter pilots are not going to be allowed to do the same as idiot FW pilots for the time being !!
