Mike Koerner Posted April 25 Report Share Posted April 25 Flight Design has updated the status of the F4 (https://flightdesign.com/flight-design-f4-aero2023). It will have the new Rotax 916 engine. First flight will be the end of this year with certification in fall of 2024. A cabin width of 134 cm = 53 in. That compares to 49 in for our CTs, an extra 2 inches of shoulder room per person. The fuel consumption of 30 l/hr = 7.9 gal/hr. The range of 1400 km = 755 nm = 870 sm. At a cruise speed of 145 kts that’s 5.2 hr of flight time. Assuming 30 min VFR reserve, that’s 5.7 hrs of fuel. At 7.9 gal/hr, that’s 45 gal usable fuel. At 6 lb/gal, that’s 270 lbs of fuel. A payload of 450 kg = 992 lb. Assuming 4 passengers at 170 lb, that still leaves 312 lb for baggage, 78 lb per passenger, compared to 55 lb per passenger for our CTs. This assumes they really meant to say “payload”. Remember there are translations involved. If they meant “usable load”, with 4 passsengers at 170 lb and full fuel, you would be left with a total of 42 lb for baggage, 10.5 lb per person. 400 T€ = $440.000 at today’s exchange rate.
