Seat belt sign usage is at the captain�s discretion and is typically activated in the presence of adverse ride conditions, or at the flight attendants� request such as during the meal service. The segment of the captain�s PA which informs the passengers that �while in their seats they are to keep their seat belts fastened� is included by many airlines as a standard procedure and a mandatory disclaimer. 8.3.10 Cruise As cruise altitude is reached, the power settings/Mach target are established. The crew also performs various administrative duties, including downlinking any departure delay ACARS codes and recording the engine monitor log (if not automated). The aircraft is usually equipped with at least two VHF transceivers and, if overwater certified, HF radios. VHF radio management usually requires one tuner to be set to the current ATC frequency, while the other is utilized for company communications or to maintain a listening watch on the universal emergency channel (121.5 MHz). If the flight extends beyond line-of-sight VHF range (oceanic and low population regions such as parts of South America), the HF units and SELCAL are used for required communications, including position report- ing. Satellite communications (SATCOM) are also used where available for both ATC and company communications. SATCOM systems offer the benefit of worldwide com- munication coverage without the signal degradation, time-of-day variability, and other deficiencies associated with HF, but are often more expensive. In addition, when out of VHF contact with ground facilities, the crew typically maintains a listening watch on the air-to-air frequency of 123.45 MHz. This channel is used to pass along operational information such as ride reports and en route weather directly between aircraft. During cruise, the crew must maintain a time/fuel log in order to compare planned time and fuel burn performance with the Actual Time of Arrival (ATA) and Fuel On Board (FOB) over each flight plan waypoint. The baseline departure (OFF) time and takeoff FOB are used to generate the Estimated Time of Arrival/Estimated Fuel On Board (ETA/EFOB) log which is usually very accurate. Consideration must be given by the cockpit crew to the possible causes of any deviations from the waypoint ETAs/EFOBs (including fuel imbalance) and the effect on the destination arrival time and fuel. Potential sources of time/burn variation in
