3PMDG 747-400 AOMDO NOT DUPLICATERevision – 26JUL05COMMUNICATION SYSTEMSRadios: The 747-400 has three Very High Frequency (VHF) communication radios for normal radio communications and two High Frequency (HF) communication radios for use while out of standard VHF radio communications range. All five radios can be tuned from any of the three radio tuning panels in the cockpit.Microsoft Flight Simulator does not have a functional HF radio model and limits the number of VHF radios that it is possible to model. As such we have not modeled the functionality of HF radio or the third COM radio.The radio tuning panels onboard the 747- 400 are located on the control pedestal. Each radio tuning panel has a liquid crystal dual frequency display, which shows both the active and standby frequencies.Crewmembers can select between the two frequencies by using the flip-flop key between the two frequency windows.ACTIVE FREQUENCY INDICATORSTANDBY FREQUENCY INDICATORACARS: (Arinc Communications Addressing and Reporting System) automatically communicates information related to the disposition of the flight via a high speed digital data link to ground personnel over the ARINC proprietary VHF radio network.Control of the ACARS system is normally through the center FMC Multi-Mode Control Display Unit (MCDU), located on the control pedestal. Any of the three MCDUs may beused, however, provided only one is used at a time.ACARS is capable of transmitting selected company reports and information, flight data and aircraft system status via discreet compressed transmissions. The ACARS system automatically transmits the aircraft as being OUT of the gate, OFF the ground, ON the ground at destination or IN the gate. These reports are made using the landing gear Air/Ground sensing equipment, as well as parking brake disposition and cabin doors. All cabin doors except the upper deck, 3L, 3R and 4R provide status information to the ACARS system.The OUT time reported is the time at which the parking brake is released after all the aircraft doors have been closed.The OFF time reported is recorded at aircraft liftoff and is transmitted after a short delay to ensure accuracy.The ON time reported is recorded at aircraft touchdown time and is transmitted after a short delay to ensure accuracy.The IN time is reported as the last time the parking brake is set before the opening of any doors.During the course of the flight it is possible to automatically or manually update the Estimated Time of Arrival (ETA) at the destination airport. Crews are encouraged to use this feature in order to ensure personnel at the downline station can accurately predict the arrival time of the aircraft.ACARS functionality is to be added as part of a future update. It is intended to include weather reporting capability and OOOI times reporting and recording.7 - 4 COCKPIT OVERVIEWRevision – 26JUL05DO NOT DUPLICATEPMDG 747-400AOMNAVIGATION SYSTEMSOverview: The 747-400 has two VHF navigation radios, three ILS/MLS receivers, and two ADF navigation radios installed. The VHF radios (designated Left and Right) provide dedicated VOR navigation radio support and can be tuned automatically by the FMC-CDU or manually by the crew. Both ADF receivers can be tuned manually by the crew.VOR Navigation Radios: Both VOR receivers are linked to directly to the FMC, and provide VOR navigation bearing and course deviation information to the crew via the Navigation Display.Under normal operating conditions, the crew will leave the VOR receivers to be tuned automatically by the Flight Management Computer. The FMC uses a logic process in order to choose VOR frequencies that facilitate triangulation of the current aircraft position as a backup to Inertial navigation and GPS position data. The VOR receiver antennas are located near the top of the vertical stabilizer.The VOR receivers can be tuned manually by using the NAV RAD page on any FMC/MCDU.VOR bearing pointers and information can be displayed on the navigation display if the crew selects the VOR L/R switches ON from the EFIS-Mode Control Panel. VOR bearing pointers are available in all navigation modes except PLN.Instrument Landing System: The 747-400 carries triple redundant ILS receivers. The ILS system can be manually tuned by the crew, or automatically tuned by the FMC.The localizer portion of the ILS shares the VOR antenna located in the vertical stabilizer until localizer capture. Once the localizer has been captured, reception is switched to the dedicated ILS-Localizer antennas located on the radome bulkhead. This is done to prevent ILS signal blanking or distortion that may result at higher pitch angles when the nose of the airplaneprotrudes into the line-of-sight path between the Localizer transmitter and the VOR antennae on the vertical stabilizer.ILS-Glideslope acquisition antennas are also located in the radome, with tracking antennas located in the leading edge of the nose gear doors. Glideslope reception switches from the radome receivers to the nose gear door receivers when the landing gear are selected down.When active, the tuned ILS frequency will be displayed on the Primary Flight Display (PFD) and Navigation Display (ND) if APR (approach) mode has been selected. The flight management computer will receive the appropriate frequency and display the decoded ILS station identifier for the crew as well.ILS tuning, either manual or automatic is inhibited under all of the following circumstances:• When localizer and Glideslope captured and autopilot engaged. • Aircraft on the ground, within localizer coverage, heading within 45 degrees of front course and groundspeed in excess of 40 knots. • Flight Director engaged, localizer or Glideslope captured
