Sector Entry And Controller Has One Turbulence PIREP
Initiated by: Hand-off from previous controller
And
Either Controller has handled an aircraft at the same altitude that reported
LIGHT Turbulence Encounter,
MODERATE Turbulence Encounter,
or
SEVERE Turbulence Encounter
Or Controller has handled an aircraft at the same altitude that reported a CAT Sensor Warning event
Modified Sector Entry:
FLIGHT CREW: “Good afternoon Boston Approach, [call sign x] flight level [XX0]”; IF no response within 30 seconds THEN repeat
CONTROLLER: “Good afternoon [call sign x], I have an aircraft ahead of you which experienced LIGHT/MODERATE/SEVERE turbulence.”
Modified Flight Crew CAT Information Response:
Flight crew turns on seat-belt sign (except in LIGHT)
Flight crew picks up intercom and tells flight attendants to get seated (except in LIGHT)
Flight crew reduces speed to turbulence penetration Mach number by pulling back on throttle levers (except in LIGHT)
Flight Crew Report of Mach Number Change, if speed greater than 464 knots (except in LIGHT)
Controller evaluates advised (speed) maneuver
Flight Crew Inquiry; IF no response within 15 seconds THEN repeat
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
CAT Encounter
LIGHT Turbulence Encounter
Initiated by: Aircraft experiences LIGHT turbulence
Modified Flight Crew CAT Information Response:
Flight crew turns on seat-belt sign
Flight crew reduces speed to turbulence penetration Mach number by pulling back on throttle levers, if speed greater than 464 kts
FLIGHT CREW: “Boston Center, this is [call sign x]. We started experiencing LIGHT turbulence
Flight Crew Report of Mach Number Change, if speed greater than 464 knots
Controller evaluates advised (speed) maneuver
Flight Crew Inquiry”; IF no response within 15 seconds THEN repeat
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 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址:DEVELOPMENT OF FAST-TIME SIMULATION TECHNIQUES(45)
