Standard instrument departure

Although a SID will keep aircraft away from terrain, it is optimized for air traffic control route of flight and will not always provide the lowest climb gradient.

SIDs in the United States are created by either the military (the USAF or USN) or the FAA (which includes US Army fields).

They are established for airports where terrain and related safety factors dictate a specific ground track be flown.

This is usually annotated in the ODP section stating, "Fly runway heading to (xxx altitude) prior to making any turns."

A hybrid SID usually requires the pilot to fly a set of instructions, then be vectored to a defined route to a transition to leave the terminal area.

[3] A SID clearance is issued to the pilot based on a combination of the destination, the first waypoint in the flight plan, and the takeoff runway used.

Thus, the LOOP5 SID at Los Angeles International Airport was so called because it was the fifth revision of a procedure that required aircraft to take off toward the west, over the ocean, and then make a roughly 180-degree turn (i.e., a loop) back toward the mainland.

Among them, the ANDIK2G Standard Instrument Departure[4] for reaching the ANDIK waypoint northeast of Amsterdam read as follows: [note 1]
