Pilot Nav
For a pilot nav SID, you will use a prepublished route that supplies headings, altitudes, and reporting
points for the transition from takeoff to the enroute structure. ATC can issue amendments to initial
clearance anytime action is necessary to avoid conflict between aircraft. When a SID is changed, confirm
what part of the SID is still in effect. If ATC desires to reinstate a cancelled SID, departure control must
state portion of routing that applies and restate altitude restrictions. The card is divided into two sections,
with a pictorial representation on top and a textual description of the departure procedures on the bottom
(Figure 14).
When performing a pilot nav SID, you must comply with the instructions published on the SID plate.
Normally, you will be assigned the SID as part of your clearance and receive no further departure
instructions. The pilot nav SID has distinct advantages: it requires a minimum of controller time and sorts
departing aircraft by initial route. On the other hand, the prepublished format of the pilot nav SID cannot
adapt to changing weather or traffic conditions.
