I believe ground speed or true airspeed is what is wanted and indicated airspeed is 'false' as it depends on the air density, which can give absurdly low values when flying high altitudesThanks RegardsShri, Indicated airspeeds are the only speeds used for reference, refer to the manual. This increased wing loading also increases takeoff and landing distances. "B741" for all -100 models). [67][68] While the 747 had the lowest potential operating cost per seat, this could only be achieved when the aircraft was fully loaded; costs per seat increased rapidly as occupancy declined. Though I was only 12 that summer and still years away from my first taste of air travel, I knew the 747 was, literally, something really big. Though the story takes place aboard an everyday Boeing 707, the film’s fictitious Trans Global Airlines had big plans to introduce the new 747. China Airlines Flight 006 (callsign "Dynasty 006") was a daily non-stop flight from Taipei to Los Angeles International Airport.On 19 February 1985, the Boeing 747SP operating the flight was involved in an aircraft upset accident, following the failure of the No. ", "Singapore Airlines Boeing 747-400 Fleet World's Largest. [13][14] In 1965, Lockheed's aircraft design and General Electric's engine design were selected for the new C-5 Galaxy transport, which was the largest military aircraft in the world at the time. If one is really serious about flying at all, one will invest the time to completely understand it at the most basic level......without fancy-schmanzy ADC and other electronic crutches to muddy the waters.The basic principles of flight are identical for all aircraft from the most humble to the most sophisticated.Presumably that's the reason why all flight instruction begins with ground school and then progresses upwards from there... :).
Larry received his B.A. [4] Initial competition came from the smaller trijet widebodies: the Lockheed L-1011 (introduced in 1972), Douglas DC-10 (1971) and later MD-11 (1990). [167], A total of 81 747-300 series aircraft were delivered, 56 for passenger use, 21 -300M and 4 -300SR versions. ", "GE's CF6 Engine Models Tailored For Boeing's 747-400XQLR Wide-Body. Its range has increased from 5,300 nautical miles (6,100 mi, 9,800 km) on the -100 to 8,000 nmi (9,200 mi, 14,815 km) on the -8I. On December 13, 1969 a test aircraft was being taken to have test equipment removed and a cabin installed when pilot Ralph C. Cokely undershot the airport's short runway. Stall speed of 747 ???? Has The Decades-Long Slide In Treasury Yields Run Out Of Road?
[37] The schedule was so fast-paced that the people who worked on it were given the nickname "The Incredibles". Raised above the main deck, the cockpit creates a hump. These cookies do not store any personal information. As the CX-HLS needed to be able to be loaded from the front, a door had to be included where the cockpit usually was. [94] Though the 747X design was less costly than the 747-500X and -600X, it was criticized for not offering a sufficient advance from the existing 747-400.

[155], The combi aircraft model, the 747-200M, could carry freight in the rear section of the main deck via a side cargo door. Most problematic was evacuation from the aircraft's upper deck; instead of using a conventional slide, volunteer passengers escaped by using a harness attached to a reel. The type had an increased fuel capacity of 48,070 US gal (182.0 m3), allowing for a 5,000-nautical-mile (9,300 km) range with a typical 452-passenger payload, and an increased MTOW of 750,000 lb (340 t) was offered. [141] The last 747-100B, EP-IAM was retired by Iran Air in 2014, the last commercial operator of the 747-100 and -100B. The aircraft does not need the full length of the runway to take off. ", "Virgin Orbit performs LauncherOne aircraft flight tests - SpaceNews.com", "Cosmic Girl takes LauncherOne on its first captive carry flight test – NASASpaceFlight.com", "FAA Regulatory and Guidance Library (PDF). The tighter the turn radius attempted, the more drag induced; this requires that power (thrust) be added to overcome the drag.
The 747SP is 48 feet 4 inches (14.73 m) shorter than the 747-100. With increased economy class seating, up to 498 passengers could be carried in early versions and up to 550 in later models. {\displaystyle \scriptstyle {\frac {v^{2}}{R}}} i [47] Over the following months, preparations were made for the first flight, which took place on February 9, 1969, with test pilots Jack Waddell and Brien Wygle at the controls[48][49] and Jess Wallick at the flight engineer's station. [91], Since the arrival of the 747-400, several stretching schemes for the 747 have been proposed. The Boeing 367-80 airliner prototype could be rolled at low altitudes with a wing loading of 387 kg/m2 (79 lb/sq ft) at maximum weight. 2 The lift coefficient is a dimensionless number which depends on the wing cross-sectional profile and the angle of attack. [45] Tests also involved taxiing such a large aircraft.
