+	<para>
+	  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.
