Diamond Aircraft DA62 flight model mod v1.12.13.5

This is no livery, this is a flight model mod. The idea is to make the flight behavior more realistic. One important detail is a realistic glide ratio of 1:10,9. Now you can flare your airplane before touch-down.

Flight model modifications version 1.12.13.5:
The book “Quest for Performance: The Evolution of Modern Aircraft” has no data about the DA62. A typical (L/D)max value for DA62 class airplane is 13. The Asobo flight model (L/D)max is 14.9, measured with the MSFS 2020 build-in DevMode tool Aircraft Editor, Debug, Sim Polar VhVs.
MSFS 2020 has no propeller drag and no ground effects. Therefore I reduce (L/D)max from 14.9 to 10.9. A smaller (L/D)max value needs a higher thrust_scalar value for the same level flight cruise speed at sea level. As second workaround I use increased retractable gear and flaps drag.

My standard set of changes for a “baseline”:
[AIRPLANE_GEOMETRY]
wing_incidence = 0 ; const
oswald_efficiency_factor = 0.77 ; const
htail_incidence = 2 ; const

[FLIGHT_TUNING]
cruise_lift_scalar = 1 ; const
parasite_drag_scalar = 1.76 ; drag_coef_zero_lift to (L/D)max adjustment
induced_drag_scalar = 1.5 ; 1.2 (sailplane, low power airplane) to 1.5 (piston, turboprop)
flap_induced_drag_scalar = 1.5 ; see induced_drag_scalar
pitch_stability = 0.04 ; const
roll_stability = 0.04 ; const
yaw_stability = 0.04 ; const

[AERODYNAMICS]
drag_coef_zero_lift = 0.032 ; 0.01 (sailplane), 0.035 (GA plane), 0.05 (aerobatics plane)
compute_aero_center = 0 ; const
aero_center_lift = 0 ; const
lift_coef_at_drag_zero = 0.1 ; const
lift_coef_at_drag_zero_flaps = 0.1 ; const

Engine.0 = 112, 0, 0.55 ; 0.6, -5.85, 0.55 ;
ThrustAnglesPitchHeading.0 = 0, 3 ; 0, 0 ;
Engine.1 = 112, 0, 0.55 ; 0.6, 5.85, 0.55 ;
ThrustAnglesPitchHeading.1 = 0, -3 ; 0, 0 ;
This is the “Static thrust bug on multi engines (and Icon A5) found!” workaround. See https://forums.flightsimulator.com/t/static-thrust-bug-on-multi-engines-and-icon-a5-found/344329
The 3° ThrustAnglesPitchHeading.X.heading angle together with the Engine.X.longitudial of 112ft result in a distance of engine to center line of 5.85ft. But the engine is far ahead of the airplane …

cruise_speed = 171 ; Knots True (KTAS)
thrust_scalar = 1.9 ; 1.15 ; Propeller thrust scalar
This parameter controls the maximum level flight air speed. I gave the airplane more power for 171 KIAS level flight at sea level.

fuel_flow_scalar = 0.9 ; 1 ; Fuel flow scalar
Set fuel consumption to 7h at 75% LVR.

empty_weight_CG_position = -3.65, 0, 1 ; -3.75, 0, 1 ; Position of airplane empty weight CG relative to reference datum (FEET), z, x, y
CG at 18.5% MAC.

flaps-position.1 = 20, -1, 1 ; 20, -1, 0.5 ;
The flaps drag results from sub-parameter Drag Coeff and flaps angle. Therefore 0 for 0° flaps and 1 for other settings gives linear progression of drag with flaps angle.

fuselage_length = -1 ; 25 ; Nose to tail (FEET)
fuselage_diameter = 4.26
fuselage_center_pos = -5.2, 0, 0.75 ; -3.7, 0, 0.75 ;
For better fit between flight model and Aircraft Editor, Debug, Sim Forces display.

lift_coef_flaps = 0 ; 0.19000
lift_coef_spoilers = 0.00000
drag_coef_flaps = 0.15 ; 0.06210
drag_coef_gear = 0.03 ; 0.00500
drag_coef_spoilers = 0.00000
Airplane has flaps and rectractable gear, but no spoilers.

toe_brakes_scale = 0.85 ; 0.66
Increase “brake power” to hold airplane with brake at nearly full thrust on ground.
