Spec range vs actual range of FSX Beech Baron

[claudej1]

What’s wrong here and how do I fix it? According to the specs. for the Beech Baron the range should be about 1569nm or 1807sm. I get 5.76 mpg at 12,000’ with mixture at max flo, propeller at 22 and power at about 20 (max power is around 26.) With 142 gallon capacity this will give me a range of 818sm. Less than half the specs. Can I change this in the aircraft.cfg file some way?

Wouldn't you want to dial down you mixture quite a bit at FL12?

Yeah, you typically don't fly with max throttle or fuel mixture, especially at higher altitudes. All this does is waste full as not all of it will burn. In real life this is also a good way to dirty up the engine.

It's a shame Microsoft doesn't include the performance charts for the aircraft so you could get the correct settings to achieve maximum range in the aircraft. I fly it at about 19-20 inches, 2300RPM and the engines leaned to 50* rich of peak.

Nobody mentioned it, so I will. When you get to cruise altitude, lean engines until it sputters (tries to die), then give it 1 or 2 notch toward rich and that's where it should be set. The EXACT amount (50%, etc) will depend on other factors, of course, but above tip is 'close enough for horseshoes', and you don't even need any gauges to set it!

I've found FS to be pretty good at hitting real world aircraft ranges. I'm just not that good at flying in a fuel conservation mode.

Of course the default aircraft are much better than many addon aircraft.

That depends upon the aircraft designer. Many purposely set their flight dynamics to have greater range and higher speeds than the real world aircraft.

There are some real high quality addon aircraft which beat the FS default aircraft.

However, I have found it much easier to hit the real world range targest with an aircraft with a fuel flow meter and to fly to the fuel flow in the real world documentation.

Raytheon's web site says the current Beech Baron will fly

948 nm @ 6,000 ft @ 25 in MP @ 2,500 rpm
1,052 nm @ 10,000 ft @ 25 in MP @ 2,500 rpm

A critical requirement is no more weight than pilot and two passengers.

The long range cruise is:
1,388 nm @ 6,000 ft @ 21 in MP @ 2,100 rpm
1,383 nm @ 10,000 ft @ 21 in MP @ 2,100 rpm


Your spec'd ferry range of 1,563 nm is going to be @ 164 kts TAS/ Ground Speed - your flight is much too high and too much power. Long Range Cruise performance is best at 6,000 ft.

The flight should take about 2 hrs per 330 nm - or approx 9 1/2 hours flight time for a 1,500 nm flight.

One other point - yes the Be-58 is certified up to 20,000 feet - but I think a check will show that the time on oxygen (above 10,000 ft) is limited - so long range cruise would not be at 12,000 ft.

From the US FAA:

"If pressurization is not an option and supplemental oxygen is not available, limit your exposure time to less than 1 hour between 10K feet and 14K feet, including not more than 30 minutes between 12K feet and 14K feet. If you have supplemental oxygen, use it above 5K feet during night flights and above 10K feet during daytime flights."

I do not see this as a RULE, but still part of the FAA procedures.

The aircraft is quite capable of flying that high for a long period of time - pilots and passengers without pressure suits are not.
