Thank you for your early responses - I expected nothing less rigorous from you stalwarts. OK the next bit:
The hot and high more specifically could be: Humidity around 85% and temp around 40-50 degrees Celcius.
Job 1: Light general HEMS work one would associate with the general populace. No great distance to transport said casualty(s). Expect max 2 casualties. Max 3 crew including pilot.
What is the best cab?
Job2: A discerning customer requiring perhaps a surgical team onboard together with associated kit. Minimum crewing: 4 including pilot(s). In addition 2 casualties.
What cab fits this scenario best?
Good to hear from the Aussies - some of the finest EMS ops in the world perhaps?
