Throttle Control and Nozzle Position:
The throttle control for this add-on works a bit
differently than for default X-Plane airrcaft. The Starfighter
has a mutli-stage afterburner with variable thrust throughout the
afterburner range. You will notice in X-Plane that the
afterburner turns on when the throttle is at about 90% towards its
forward position. The remaining 10% of the throttle movement
controls thrust in the afterburner stages. Nozzle position as
shown in the graph below is the primary indicator of afterburner
operation. The nozzle will fully close in military thrust and
will be reading close to 1 on the nozzle position gauge. As the
afterburner lights, the nozzle will open again and will read close to 8
when in maximum afterburner. In real life the nozzle position is
varied to keep EGT below 600 degrees. The engine EGT should be
stable at slightly below 600 degrees with the afterburner on.
The CF-104 plugin features a custom engine model to provide accurate
thrust settings to provide level speed values and acceleration values
to match the charts within half a percent throughout the subsonic and
supersonic flight range.
T2 Reset and Cutback
This affects engine rpms at high speeds or low outside air temperatures.
When you cut the throttle at high Mach numbers (high compressor inlet
temperatures) the engine rpms will not decrease to prevent compressor stall. At
very cold temperatures, max engine rpms are limited.
