Standard Operating Procedures (SOP)
NOTE: Above Ground Level (AGL) vs Mean Sea Level (MSL)
- AGL (Above Ground Level) is your aircraft’s height above the terrain directly below you. It’s most useful for low-level operations and obstacle clearance.
- MSL (Mean Sea Level) is your altitude above average sea level. It’s the standard reference for navigation, charts, and published altitudes.
FSFO will trigger the actions listed below when the aircraft reaches the specified AGL or MSL value. Setting a value to 0 disables that trigger.
