Morning
Thanks. We can not go bigger than the machines listed. The 412 is a touch and go. The problem with the range is the return flight. Most flights approximately 1 hr to 1.5 to destination. If we do not have close to 3 hrs range, we will have to deploy fuel to all the hospitals which creates problems.
Based on performance only, 2 B3's per site would have been an almost perfect scenario. Unfortunately regulations are forcing us to seek a twin and thus 2 patients/machine. Obviously, we need a safety margin in the machines performance as well. No use we pull max TQ/N1 every take off otherwise we may just as well buy BO105's for next to nothing and operate under the smoke screen of a twin ops.
