Gulfstream G450 Aircraft Service Change 072“December 22, 2011”The design change effected by this Aircraft Service Change (ASC) has been classified asMajor/Not Significant by the United States Federal Aviation Administration (FAA) and Level 1Major/Not Significant by the European Aviation Safety Agency (EASA). The design changedata contained in this document is approved and accepted by the FAA and EASA underGulfstream Organization Delegation Authorization (ODA) project numbers: FAA – Project Number TD-01-2009-0005 EASA - Project Number TD-01-2010-0023The design of this ASC is approved by aircraft type design data for installation on aircraftregistered for operation in accordance with applicable regulations of the FAA or EASA.The design of an ASC is configured to a standard (“green”) production aircraft. If spare wires,pin connections or locations called out have been used for another modification, the installingagency must ensure the development, documentation and approval of any requireddeviations.The following instructions, in step-by-step form, are written as a guide to perform this ASC.Compliance with safe maintenance practices, as defined in the Aircraft Maintenance Manualand FAA or EASA regulations, is required. It is the responsibility of the installing facility toread all instructions contained in this service change and refer to all associated documents,drawings and manuals for applicable actions.Gulfstream considers this ASC a means to enhance aircraft capabilities to meet individualoperator requirements. The modification is not related to any safety or airworthinesscondition.Subject:Indicating / Recording (ATA 31) – Data Link RecordingPurpose / Discussion: This service change provides the necessarymodifications and software to activate the Data LinkRecording (DLR) function on aircraft equipped withController Pilot Data Link Communications (CPDLC).CPDLC is a method of air-to-ground communicationbetween pilots and air traffic controllers utilizing the datalink system to exchange messages. This system iscurrently employed in conjunction with traditional VHFradio communication to reduce the quantity of voiceradio ATC traffic required.CPDLC is utilized globally and is an operationalrequirement in many of the most heavily traveled ATCsectors. Due to this requirement and the extensive useof CPDLC with commercial aircraft, approvingauthorities in many areas now require a record of thesemessages similar to the recording of voicecommunication by the cockpit voice recorder (CVR).DLR is the recording of Controller Pilot Data LinkCommunications (CPDLC) messages.Page 1 of 10
