Light Twins: Performance versus Cost
Assistance Required:
I am looking for a comparison between a couple of light twin helicopters (AS355N, B105, BK117, A109 any other suggestions??) to operate offshore up to about 15nm. I have searched the web, but was unable to gather sufficient information.
Could any operator flying these models, provide me with some performance/hourly rate figures? Below is the requested format. Alternatively, contact me via a private message.
