75:: As of 1.9.0, in the c182, the altimeter is not self-consistent. There is an analog scale and a digital readout. It takes 10 clicks of the Kollsman setting knob to move the digital readout ten hundredths of an inch. It takes 14 or 15 clicks to rotate the analog scale the corresponding amount.
Neither readout appears to produce entirely accurate altimetry, although the analog scale is clearly worse. This is highly unrealistic. There exist other altimeter models that are both prettier and more functional. 76:: Newton’s laws are still being violated by environment.cxx. The pressure profile (P versus h) is incorrect. This has many consequences. It greatly affects altimetery, but also affects engine performance, airfoil performance, et cetera. In particular it means the simulator fails to exhibit the HALT phenomenon (high altimeter because of low temperature). For quantitative details on this, see http://www.av8n.com/fly/fgfs/htm/bug-list.htm This bug has been known for years. The code to fix it was written years ago, but not incorporated. 77:: In the default c172p model, sitting on the runway at KSFO, at full power the engine consumes about 78 pph of fuel. So far, so good. Now stop the engine by pulling the mixture to cutoff. I observe that the fuel flow, as reported by the FDM via the property tree, settles above 8 pph. That’s more than a gallon per hour, with no mixture and no revs. That seems like rather a large leak. Similar phenomena have been observed in other aircraft models. 78:: As of 1.9.0, in the c182rg, I observe that the menu item "reload panel" doesn’t reload the panel. Shift-F3 doesn’t reload the panel either. ------------------------------------------------------------------------------ Check out the new SourceForge.net Marketplace.
