F4-BMS 2.0 Technical Manual
7 AIRCRAFT
With BMS comes great improvements to other aircraft in the Falcon virtual universe.
For aircraft specific features listed below, the appropriate settings in the aircraft data file need to
be set. These settings are detailed in the BMS Appendices.
7.1
DYNAMIC ROLL INERTIA
The inertial effects of stores on the wings is now factored into the rolling inertia of aircraft. The
effect also takes into account the fuel weight in external tanks. A player will notice that a fully
loaded aircraft will react in a more “sluggish” manner. Both starting and stopping of rolling
maneuvers will need more attention. As weapons are released and fuel is used, this inertia will
decrease.
7.2
TWO ENGINES
The Falcon code now fully supports two engine operations. When flying a two engine aircraft, the
player can control the left, the right, or both engines with his throttle. Each engine has its own
thrust, fuel flow, damage modeling, etc. Be advised that adverse yaw and roll are also modeled
when there is asymmetric thrust!
When an aircraft has two engines enabled, the upper left corner of the screen will display the
current engine selection (BOTH, LEFT, RIGHT) and the rpm of both engines. To cycle between
engines, use the CTRL-O key (known as the CycleEngine command when using different key
mappings). When LEFT or RIGHT is selected, the throttle will only control the rpm of the engine
selected.
For engine startup or shutdown, the procedures are the same as with the single engine operation
except that LEFT or RIGHT engine must be selected.
7.3
F-16
Along with adding two engines, improvements have been made to the single engine functions as
well. For F-16 aircraft using the PW220 Engine:
Engine idle increases from Mach 0.84 to Mach 1.4 when it will be at MIL power from 1.4 and
above.
The afterburner has 3 schedule zones. Area 3 is Segment 5 no light. Area 2 is Seg 1 light only.
Area 1 is no AB available. These are based on various low speed and altitude regimes.
Engine will increase idle speed based on altitude
Engine will increase spool up/down time based on altitude/speed.
