starterRPM: "RPM during engine startup. Higher starts faster. Too high = unrealistic.",
idleThrottle: "Throttle at idle. Higher means more thrust at 0% throttle.",
fuelFlow: "How fast fuel is consumed. Higher = more realistic consumption, lower = longer flights.",
enginePower: "The base power of the engine. Higher = more thrust and acceleration.",
brakeRPM: "RPM at which braking effect is active. Higher = faster deceleration.",
wingArea: "Total wing surface. More = more lift. Too much = unrealistic flight.",
dragFactor: "How much drag affects the aircraft. Higher = slower top speed.",
liftFactor: "How efficiently the wings lift. Higher = easier takeoff & climb.",
CD0: "Parasitic drag coefficient. Higher = more drag.",
CLmax: "Max lift coefficient. Higher = more lift before stalling.",
elevatorFactor: "Effectiveness of pitch control. Higher = more sensitive.",
rudderFactor: "Effectiveness of yaw control. Higher = tighter turns.",
aileronFactor: "Effectiveness of roll control. Higher = faster rolls.",
mass: "Total aircraft mass. Higher = slower response, more stability.",
emptyWeight: "Weight with no payload. Affects takeoff performance.",
maxWeight: "Max takeoff weight. Higher allows more payload.",
inertia: "Aircraft rotational inertia. Higher = more sluggish pitch/yaw/roll.",
pitchMoment: "How much pitch resists change. Higher = smoother pitch.",
yawMoment: "Yaw stability. Higher = less yaw wiggle.",
rollMoment: "Roll stability. Higher = steadier rolls.",
gearDrag: "Drag caused by landing gear. Higher = slower when deployed.",
gearCompression: "Suspension compression. Higher = softer landings.",
gearLength: "Length of gear strut. Higher = taller aircraft stance."
