+ 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. + +
