Please Note as at 10 March 2022 since latest update this Bush Trip doesn't appear to work with the selected helicopter. I'm told problem has been reported but no joy as yet. I expect I'll have to remove it eventually

Firstly you need the Airbus H135 helicopter:

I wanted to explore the use of the helicopter and after much trial and error I came up with this BushTrip. This flight is a Medical Mission. You will pilot the Airbus H135 Helicopter on a trip from its base in Besançon to Paris and back.  You must be prepared to make some diversions to accommodate the patients' wishes. The flightplan allows you to check out some sightseeing but there are some difficult moments with opportunities to land in exceptional locations.  

Note: I have created several Helipads and there are some landing areas located at waypoints and not always at the end of each leg. The route in Paris criss crosses the city and some helipads are close together, take care landing on the correct pad. You may want to open the flightplan in a mapping app such as Little NavMap and maybe switch the MFD to Map (DMAP) and pop it out as a separate window (Right Alt and LM click). 
Good Luck.

Notes-
Length: 582 nm, 
Time: 4 h 24 m (variable!)
Refuel/Repair - ALT+Shift+R  (or set your own dedicated key/mouseclick)
GPS/Flight Plan. The flight plan display may drift after a crash or restart but the correct leg can be selected in the 'Tablet' or Garmin screen. (It takes a few seconds for the waypoint options to be displayed)

Optional Addons are available for the areas covered by the flight, however I have had difficulty using this BushTrip with them due to differences in the way altitudes and maps have been used.
