Light - electricity interactions are a model design matter. Granted, this behaviour should not exist in default aircraft (as well as inverted switches, nonworking animations, etc, etc...), but it's not a core sim engine issue.
Good catches though, especially for the ground friction, flap stall and superchargers.
Not sure if it's practically achievable with the flight model, but in theory, it should be possible to make the number of engines, fuel tanks, payload stations, etc... procedural, i.e. not limited to a set upper value (engines, payload stations) and not tied to a specific name (in case of the fuel tanks).
27) Mixture affects turboprops and jet engines on an on-off basis. Either make these engine types independent from the sim's mixture setting or affect output power
28) The icing model is much too timid. In FSX, the current weather requires an "icing" flag to have that dreaded stuff build up on the airframe. This flag is, however, rarely set by either the internal real world weather or third party tools, which renders icing basically harmless in FSX. In the rare case of working "icing" flags, ice will only apply a weight penalty on the aircraft instead of also affecting drag. Carburetor and pitot icing does also not gradually affect your engines, but will simply fail them after a certain amount of ice buildup. Engine icing (i.e. inlets) also does not gradually affect power output. If a better icing system is implemented, it would be nice to be able to scale ice susceptibility in the aircraft.cfg.
29) Fuel injected engines still suffer from carburetor icing.
30) I'd like to see a more dynamic flap system, where you can assign a pitch and drag offset to a specific flap position instead of a general offset evenly divided by the number of positions.
More supported positions would also be nice. Currently, the limit is 8 or so which is not practical for aircraft using a flap system without detents (e.g. DC-3).
31) Gear drag influenced by position (=50% drag at 50% extension) instead of a simple offset at full extension.
32) Atmospheric modeling from 36000 ft until the edge of space might increase popularity with pilots of high performance aircraft as well as increasing the current mach limit of 3.2 times the speed of sound.
33) System failures, e.g. for the hydraulic system can not be toggled via write-type variables (i.e. EventIDs) and there is no variable to read the current failure state of a system save for the engines or some avionics. If you cross-check the failiure menu with the official simulation variable and EventID lists, you will notice that a lot of systems failures can only be accessed from the menu.
34) There's not even a simple simulation of oil or hydraulic fluid use and leakage. Unless you toggle a failure from the menu, the gauges indicating quantities will never move. A scalar in the aircraft.cfg, akin to "Max_oil_quantitiy=nn" and "oil_use_nominal=nn" (with oil consumption scaling with engine RPM) and "max_hydraulic_fluid_quantity=nn" and "hydraulic_fluid_leakage_rate=nn" (with leakage rate dependant on the use of hydraulic-powered systems) could help here. Current quantities can be tracked in the flight save file and refilling the reservoirs can be done from the fuel menu or with the fuel truck or on refueling parking spots.
