Many companies want to fly their employees a 1,000-mile trip nonstop. For example a distance between Dehradun and Chennai which is 712 NM / 1320 KM can be done in a flying time of just over 4 hours without any refueling stops.
This is best achieved by Pilatus PC-12 NG single-engine turboprop, which can lug at least 1,200 pounds of payload (passengers and cargo) over 1,000 miles. And the PC-12 NG can fly the trip at maximum cruise speed of around 260 knots, Having great range is a terrific asset for any airplane, but there is an adage in aviation that an airplane can “outfly its cabin,” meaning the endurance of the passengers expires before the fuel supply does. While most pilots are willing to sit in a cramped cockpit for hours on end to avoid a fuel stop, passengers are not. They demand room to move around, a private and usable lavatory and access to drinks and food.
Again, the PC-12 stands out for having a cabin almost 17 feet long and 5 feet wide, with 4 feet 10 inches of headroom. There is a private lavatory, and luggage is accessible in the rear of the cabin while in flight. The cabin equals, or at least rivals, some midsize business jets that have similar range.
