Flight Crew Inquiry
Controller Response to request for ride report
Flight Crew Request for Altitude Change to smoother ride altitude if known, or else to either 4,000 feet above (preferably), or 4,000 feet below; IF no response within 10 seconds THEN repeat
Controller evaluates requested (altitude) maneuver
Altitude Change Clearance
IF controller is unable to comply with altitude change request AND aircraft continues to experience CAT or CAT warnings THEN wait 60 seconds; return to Flight Crew Inquiry part of sequence
“Party-Line” Information on PIREP 2,000 Feet or 4,000 Feet Above or Below Own Altitude
Initiated by: Another aircraft at a different altitude than own aircraft but within 4,000 feet of own aircraft and on same route or [z] nm from own route has provided Flight Crew Report of Mach Number Change
or
Another aircraft at a different altitude than own aircraft but within 4,000 feet of own aircraft and on same route or [z] nm from own route has provided Flight Crew Inquiry
Modified Flight Crew CAT Information Response:
Flight crew turns on seat-belt sign, if not already on (except in LIGHT)
Flight crew picks up intercom and tells flight attendants to get seated, if not already done (except in LIGHT)
Flight crew reduces speed to turbulence penetration Mach number by pulling back on throttle levers, if speed greater than 464 kts (only for SEVERE)
Flight Crew Report for Mach Number Change, if speed greater than 464 kts (only for SEVERE)
Controller evaluates advised (speed) maneuver

CAT Sensor Warning
Initiated by: Flight crew gets visual warning from CAT sensor
Modified Flight Crew CAT Information Response:
Flight crew turns on seat-belt sign, if not already on
Flight crew picks up intercom and tells flight attendants to get seated, if not already done
Flight crew reduces speed to turbulence penetration Mach number by pulling back on throttle levers, if speed greater than 464 knots
FLIGHT CREW: “Boston Center, this is [call sign x]. We received a turbulence alert
Flight Crew Report for Mach Number Change, if speed greater than 464 knots
Controller evaluates advised (speed) maneuver

Emergency Situation
Assuming that the simulation enables an aircraft encounter with severe turbulence without two-minute flight crew warning, an emergency situation could be triggered.
SEVERE Turbulence Encounter without Warning
Two-minutes after exiting the severe conditions:
