This sounds fairly accurate. Other comments about passing other planes or having a ground speed of 250 kts has no bearing on the true performance of a plane. There are a couple of days I could have had a C-182 doing 200 kts over the ground. Meaningless. P Baron = $$$ maintenance, so I've heard. Duke = $$$$$$$$ maintenance and big gas and runway guzzler. What is the premise of the paper? Are you looking for certain price ranges to start? Are you trying to define a client/customer for this study? Payload considerations?Lrjtcaptain said:The B58 Baron is an excellent airplane. I was flying a 1994 B58 with IO550 n/a and we figured operating cost of the airplane was $170 an hour.
The Duke however would be a different story. Don't know operating cost of the duke but i know it spends most the time in the mant. hangar.
Twin cessnas are more roomy for pax comfort then a baron, but on a performance level, id take a Baron any day of the week. Plus most twin cessnas have higher operating costs.
Flew an old PA31-325TC navajo back in the day. Quite expensive to operate, about $350 an hour at 180kts but spent alot of time down due to mag/alt/turbo problems. The baron never really had too many issues yet figured an average TAS of about 195KTS.
I can believe a Chieftan doing 215 at 18,000, but how many operators do that? Were you flying freight with no pax and using a cannula or mask? Finding the "perfect" twin or any aircraft for that matter is going to be a compromise and fairly subjective in the end. Define the mission - speed, range, payload, performance, cabin class, purchase cost, maintenance cost, insurance cost, etc. Many airplanes to choose from. Hope they find a viable solution to the pending AVgas shortage in the future. Try some of the site that provide aircraft comparisons - AOPA, planequest, chiefpilot, Conklin & de Dekker, etc. (Some info is free - others not) Good luck.
