· Ensure that the minimum required cabin crew remain onboard and are positioned throughout
the cabin in accordance with appropriate regulations (FARs 121.391 & 121.393/JAR-OPS
1.990).
· Ensure that all cabin electrical equipment is turned off.
· Implement security procedures (see Section 4).
· Disembark after all passengers have left the aircraft or until relieved by another cabin
crewmember.
2.9 TURBULENCE
2.9.1 General
Turbulence is the result of atmospheric or environmental effects. En-route turbulence accounts
for a substantial number of cabin crewmembers injuries and can occur at anytime and at any
altitude. Turbulence can be expected or it can be sudden and unexpected. Intensity can vary and
is relative to location of the occupants in the aircraft (generally the aft of the aircraft will
experience greater turbulence intensity than the front).
In the event of light chop/turbulence, the PIC should turn on the Fasten Seat Belt sign. The cabin
crew should make the appropriate announcement and should ensure that all passengers are seated
with their seat belts securely fastened.
In the event of moderate turbulence, cabin crewmembers should secure loose items and secure
themselves in the jump seats. Communicate with the flight deck crew for the anticipated duration
of the turbulence.
In the event of severe turbulence, cabin crewmembers should secure themselves immediately in
the closest seat or whatever means is available. This could include sitting on the floor, when no
other means is available.
The safety of the cabin crewmembers is paramount during turbulent conditions because if they
are injured, passenger’s needs cannot be met.
2.9.2 Pre-departure Crew Briefing
The PIC should include a weather/turbulence briefing with the standard pre-departure briefing,
and cabin crew should pay particular attention for turbulence forecasts. The weather briefing
should contain the following:
· Discussion of critical Exposure Periods (which could include take-off, cruise over known
areas of turbulence and descent)
· Expected en-route weather
· Forecasted turbulence location (in terms of flying time and degree of reported turbulence)
· The timing of weather updates to the Lead Cabin Crewmember
· Communication of possible service modifications prior to expected turbulence encounters
· Establishment of the ‘all clear’ signal

2.9.3 Turbulence Procedures During Flight
While in flight, the flight deck crew should communicate with the cabin crewmembers if
turbulence is expected or encountered. The cabin crewmember should immediately communicate
this information to the other cabin crewmembers. Cabin crewmembers should prepare the cabin
according to the level of turbulence anticipated.
Communication must flow two ways. Cabin crew should not wait for the flight deck crew to turn
on the “Fasten Seat Belt” sign. If conditions dictate, the cabin crew should make PA’s instructing
passengers to return to their seats and fasten seat belts, then request the flight deck crew to turn
on the “Fasten Seat Belt” sign.
NOTE: If a reasonable amount of time has elapsed with no turbulence and the Fasten
Seat Belt sign remains on, cabin crewmembers should initiate contact with the flight deck
crew via interphone in order to determine if it is safe to resume duties.
2.9.4 Unanticipated Turbulence
When moderate or greater turbulence is encountered unexpectedly, cabin crew should:
· Immediately take the nearest seat or jump seat and fasten seat belt and shoulder harness
· Direct passengers via PA to fasten seat belts
· Do not take time to secure loose items/galley
· If a reasonable amount of time has elapsed with no turbulence and the Fasten Seat Belt sign
remains on, the cabin crew may initiate contact with the flight deck crew to determine that it
is safe to resume duties
2.9.5 Anticipated Turbulence
When notified by the flight deck crew that turbulence is anticipated, the Lead Cabin
Crewmember should:
· Ask how much time is available prior to the encounter, anticipated intensity and duration of
the turbulence, the ‘all clear’ signal and any other specific information/instructions
· Ensure all cabin crewmembers are given the same information
· Ensure steps to secure the cabin are accomplished in priority order; time available will
