Anyway - I agree that I could have chosen my words a bit better - but do you agree on the rest of my post? |

I am no expert, so please go easy with me as I try to clear the fog in my head over all this, but I assume that the above speeds for the Hurricane and Spitfire would be increased at low level with operation of the emergency boost cut-out with 100 Octane fuel (by approx 30 mph)? Or have I got the wrong end of the stick? Happy landings, Talisman |
How many Kms slower is a 109 speedometer at sea level than actual true airspeed?

I didn't buy CoD to get BoM. I'm not buying BoM to get CoD either. I want CoD as advertised (or even in the ballpark). Then I 'll consider buying BoM. There are a lot of CoD owners who feel the same way. And yes if you buy BoM and they don't fix CoD you are asking to get ripped off a second time and that would be a sucker. If they fix CoD, then no worries. |

True airspeed, or TAS, is a measure of the physical speed of the aircraft in relation to the air around it. Just as differences in wind velocity affect groundspeed, differences in air density affect true airspeed. At the same engine power setting, e.g., 75 percent power, an airplane can move faster through air that is less dense. That’s why higher altitudes can translate to higher true airspeeds. Like aircraft groundspeed, TAS cannot be measured directly. Rather, the pilot uses outside air temperature (OAT), pressure altitude, and calibrated airspeed CAS to calculate this value.

http://www.tscm.com/mach-as.pdf The complexities gather...... Assume its a standard day and the ASI reading = 'calibrated' = True Airspeed at sea level. You'll lose less sleep. Anyone know what kind of day we have in CoD? |

If the 1.23 ata speeds can't be met, then there is something definitely wrong with the FM. |
