case the engine will go to the Run phase. Once an engine is in the Off phase
the full starting procedure (or airstart) must be used to get it running.

- -STARTING (on ground):
- -# Set the control FGEngine::Starter to true. The engine will spin up to
- a maximum of about %25 N2 (%5.2 N1). This simulates the action of a
- pneumatic starter.
- -# After reaching %15 N2 set the control FGEngine::Cutoff to false. If fuel
- is available the engine will now accelerate to idle. The starter will
- automatically be set to false after the start cycle.

Ignition is assumed to be on anytime the Cutoff control is set to false,
therefore a seperate ignition system is not modeled.

+Definition of the turbine engine configuration file parameters:
+<pre>
+<b>MILTHRUST</b> - Maximum thrust, static, at sea level, lbf.
+<b>MAXTHRUST</b> - Afterburning thrust, static, at sea level, lbf
+[this value will be ignored when AUGMENTED is zero (false)].
+<b>BYPASSRATIO</b> - Ratio of bypass air flow to core air flow.
+<b>TSFC</b> - Thrust-specific fuel consumption, lbm/hr/lbf
+[i.e. fuel flow divided by thrust].
+<b>ATSFC</b> - Afterburning TSFC, lbm/hr/lbf
+[this value will be ignored when AUGMENTED is zero (false)]
+<b>IDLEN1</b> - Fan rotor rpm (% of max) at idle
+<b>IDLEN2</b> - Core rotor rpm (% of max) at idle
+<b>MAXN1</b> - Fan rotor rpm (% of max) at full throttle [not always 100!]
+<b>MAXN2</b> - Core rotor rpm (% of max) at full throttle [not always 100!]
+<b>AUGMENTED</b>
+ 0 == afterburner not installed
+ 1 == afterburner installed
+<b>AUGMETHOD</b>
+ 0 == afterburner activated by property /engines/engine[n]/augmentation
+ 1 == afterburner activated by pushing throttle above 99% position
+ [this item will be ignored when AUGMENTED == 0]
+<b>INJECTED</b>
+ 0 == Water injection not installed
+ 1 == Water injection installed
+</pre>
