+ Apogee Lockout
+
+ Apogee lockout is the number of seconds after boost where
+ the flight computer will not fire the apogee charge, even if
+ the rocket appears to be at apogee. This is often called
+ 'Mach Delay', as it is intended to prevent a flight computer
+ from unintentionally firing apogee charges due to the pressure
+ spike that occurrs across a mach transition. Altus Metrum
+ flight computers include a Kalman filter which is not fooled
+ by this sharp pressure increase, and so this setting should
+ be left at the default value of zero to disable it.
