Recommend not using VS for climb - you run the risk of running out of airspeed while the plane attempts to maintain a 2000’ rate of climb. You will stall out and leave controlled flight.
Use FLC (Flight Level Change) instead and set the airspeed to 124 knots. This is the best climb speed possible in the plane as determined by testing and listed in the POH (Pilot’s Operating Handbook).
It’s also noted on the PFD airspeed tape if you use the Speed Bugs icon and turn ON all bug carets. Note the Y 124 which denotes Vy or best climb speed.
Instead of trying to maintain a 2000 foot per minute rate, the aircraft will stay at 124 knots and whatever climb rate you get at that speed is the best combination with a speed safety margin so you don’t stall.
Use VS for descent instead - with a recommended 1200 foot per minute rate which gives gentle 3.3 degree deck angle - very kind to the passengers so they don’t feel like they’re going to fall forward out of their seats.
