I have been a fan of the Beech 18 for quite a while. I got a ride in one from the Boston area to Richmond, VA and back in the early 1970's. It was not a jet but it got the job done for a one-day business trip. (Okay, it was a long day!) We have kicked around an FS model of the Volpar for a few years. I just got a little more serious about it and tuned up the FD to meet published specs for speed, range and tankage.
There is an ad today for a "1954 Beech 18 Volpar" so that may make it eligible for use in the GAAR.
The following specs were obtained from Jane's All The World's Aircraft:
Cruise at 5000 ft and 66.7% power: 180 KTAS.
Range at 10000 ft and 44.4% power: 1414 nm.
My Power Gauge for 450hp is used in finding the percent power. Because 2300 rpm is the max recommended (continuous) for the engine, that is what I have used to set up the cruise table. You can use lower RPM at the same power level but will need slightly higher MAP.
FS9 Beech 18S Volpar
ALT FT__POW %__RPM___MAP___KIAS___KTAS___GPH___NMPG___RANGE nm
__5K____44.4_____2300___20.0____135____145_____14.5___5.00_____1212
__5K____66.9_____2300___26.3____168____180_____21.8___4.13_____936
_10k____44.4_____2300___19.7____128____148_____14.4___5.13_____1231
_10k____66.8_____2300___26.2____162____187_____21.8___4.31_____954
Notes: Climb at 80%. Range includes 1 hour reserve. Max gross weight at takeoff with full tanks was used for range estimation with no wind. All testing at Standard Day conditions (Clear Skies).
The payload for the testing was 2 crew (200lb ea) plus 6 pax (180lb ea) plus 120 lb baggage. The CG was at 26.4%.
For a copy of these FD files, send me an email.
