aircraft's wake turbulence. It was a very distinct yet rather gentle roll from level
wings to approximately 40 degrees left wing high. I recovered quickly and
experienced no subsequent unusual wind encounter prior to touchdown. Pilots
hearing 'wind calm' on the runway should keep in mind that ground friction and
other local obstructions may change the wind's characteristics immediately above
the runway, and that 'wind calm' does not guarantee calm winds above ground
effect.
Synopsis
A C182 pilot reports a wake vortex encounter at 350 ft following a Citation into VNY
Runway 16R.

Narrative: 1
Flight was about an hour behind schedule. Maintenance was in cockpit during
cockpit preparation clearing previous MEL. No PDC available. Received verbal
clearance. Clearance was BXK2 PMD as filed. Dispatch release indicated 'NONSTANDARD
ROUTE.' BXK2 was entered into the FMC, confirmed, and briefed. BXK2
was filed and understood. Pilot not flying had CHILLY departure hanging on yoke
clip. Captain was pilot not flying, First Officer was pilot flying. Normal through
takeoff and climb. Moderate wake turbulence from preceding aircraft was
encountered during climb out and departure. Near 4 DME a turn to the north was
made. After turning pilot flying realized that the BXK2 required a right turn to the
south and began to turn right. At this time ATC queried our turn to the north and
departure. Some discrepancy arose and ATC then issued a turn direct to ZEPER.
ZEPER was entered manually into the FMC as it is not on the BXK2. A frequency
change was issued and the next Controller indicated there may have been some
discrepancy with our routing. He then issued new routing and gave us a phone
number to call. Ensure proper departure is flown and ensure proper departure is
displayed in front of the pilot flying. Supplemental info from ACN 824408: Near 4
DME and prior to turning 100 degree heading on BXK departure. Pilot flying turned
aircraft slightly left. Pilot not flying assumed another movement to displace aircraft
for wake turbulence. I failed to query turn to north assuming it was an aircraft
displacement for wake turbulence. While handling pilot not flying duties and
assuring safe separation and aircraft control, I questioned myself with what I
thought was the proper clearance.
Synopsis
B737-300 on departure encounters wake turbulence from the preceding aircraft.
Subsequent to the initial wake event, the pilot flying deviated from the SID and the
pilot not flying incorrectly assumes it is a wake avoidance maneuver.
