* The C182 model does not realistically capture the flap/power/trim interaction. In the model, extending the flaps seems to cause a nose-down pitching moment, which is the wrong direction. And the power-dependence of the effect is not realistically modelled. In a real C182 / C172 / C152 / C150, the flap/trim interaction can be described as follows: | |||
** Changing the flap setting has little effect when the engine is at idle. | |||
** Changing the power setting has little effect when the flaps are in the retracted position. | |||
** However, there is a multiplicative effect: Adding power causes a nose-up pitching moment when flaps are in an extended position. Or, to say the same thing, extending the flaps causes a nose-up pitching moment. The effect is in proportion to the amount of power being developed *times* the amount of flap deflection. | |||
* The model seems never to consume any fuel. I dumped the property list and discovered that engines/engine/fuel-flow-gph takes on reasonable values and tracks the throttle setting, while engines/engine/fuel-flow_pph remained stuck at zero. This is a particularly bad disconnect, since apparently the latter is what gets integrated to calculate engines/engine/fuel-consumed-lbs. | |||
Desirable creeping features: | |||
* Retractible landing gear. This would increase the value of the model for "transition training" for pilots transitioning into complex aircraft. | |||

* horizon instrument is in wrong position after doing some wild flying maneuvers. This is a realistic model of a tumbled gyro. | |||
* cockpit window has no windscreen wipers. This is realistic. | |||
