What is required during a Standard Instrument Departure (SID) at a military field?

During a Standard Instrument Departure (SID) at a military field, the requirement to climb to at least 400 feet above the Departure End of Runway (DER) elevation before initiating a turn is a critical safety measure. This altitude helps ensure that the aircraft gains sufficient altitude to clear any obstacles in the flight path immediately following takeoff.

Gaining this altitude is essential for maintaining a safe vertical separation from the terrain and any nearby obstructions, which could pose a risk to flight safety if not adequately considered. By establishing a minimum climb altitude of 400 feet above the DER elevation, pilots are afforded a margin that contributes to safer operations, particularly in environments where military operations or terrain may be unpredictable.

Other options may suggest different altitudes or turning parameters that do not align with the established guidelines for safe departures, thereby highlighting the importance of adhering to the specified height before initiating turns during a Standard Instrument Departure.
