RJGHT International, II January 1968 54-55 lets and containers. There are two sorts of underfloor container. System concepts are generally new and reflect the fundamental objective of fully automatic approach and landing capability at an early date. The electrical system has split parallel busbars, each ©f which can be isolated. There are four 60kVA generators (despatching and continuous flight is possible with one inoperative) and there are two similar generators (with a 30min 90kVA rating) driven by the tail-end-mounted APU. The triplicated hydraulic system powers the flying controls which, for the first time on a Boeing, are without any alternative form of power. In all their decision making, Boeing took a long, hard look at the inter- continental business and conjured with many stretches and developments of the 707 before finally deciding to go ahead with the massive 747. It was an in- credibly bold decision, perhaps one of the most ambitious in the history of commercial aviation. r-UPPER EQUIPMENT \ CENTER LH \ • AUOtO EQUIPMENT » SftCAl NS BATTERIES FORWARD EQUIPMENT CENTER (LH AND RH)* • WEATHER RADAR EQUIPMENT CENTER RH • ESSENTIAL BATTERY CHARGER • T-R UNITS • STATtC INVERTER CENTER FUSELAGE EQUIPMENT CENTER AFT) • AOf • tOW RANGE RADIO ALTIMETER ' CENTER FUSELAGE EQUIPMENT CENTER (FWD) • SPACE PROVISIONS ONLY -MAIN EQUIPMENT CENTER • AVIONiC EQUIPMENT • COMMUNICATIONS • NAVIGATION • AKS • EUCTRICAl POWER CENTER • ELECTRICAL EOU1PMENT • ANTISKID • AIR-CONDITION • EXTERNAL POWER RECEPTACLES APU BATTERY AFT EQUIPMENT CENTER • VOICt RECORDER • FLIGHT RECORDER • APU CONTROL MODULE AND BATTERY CHARGER • ACCESS DOORS TO EQUIPMENT CENTERS!

Use of the spoilers is also being considered for direct lift control to set rate of descent on the approach.
