There has been an increase in pilot deviations during the last 18 months.  These pilot deviations are coming from pilots who are flying Standard Instrument Departures out of Van Nuys Airport (VNY).

A review of these deviations showed most are occurring when pilots on the SIDs departing from Van Nuys Airport are commencing a turn on course prior to being issued radar vectors from the Southern California TRACON controller.

These early turns are causing:

• aircraft to lose separation with those flying into Burbank Airport on Runway 08
• aircraft to lose separation with obstruction and terrain clearances
• other indirect separation issues for aircraft landing at both Los Angeles International Airport and Santa Monica Municipal Airport.

The FAA is reminding pilots to pay strict attention to the narrative on the SID.  As stated, of particular concern is the "expect radar vectors" portion described.

Below is an example of the CANOGA departure.  The red arrows indicate what is happening with the pilot deviations we have been seeing.  While this is only one example on one SID, these are the types of things we have seen on several SIDs departing Van Nuys Airport.
