a few landings a month or is it more?
Define a few?
FWIW in my 15'ish years in the RHS on the fleet I averaged 2 or 3 landings in an average month. It can be very variable - anyone who picks up a lot of two pilot trips (e.g. US East coast) might get 4-5 a month, the guys who pick up the 3 or 4 pilot trips are going to do less.
