Mean aerodynamic chord (MAC) is defined as: [6] = (), where y is the coordinate along the wing span and c is the chord at the coordinate y.Other terms are as for SMC. The MAC is a two-dimensional representation of the whole wing. The pressure distribution over the entire wing can be reduced to a single lift force
Location of Bawean. The incident began at 11:38 UTC+7:00 on 3 July 2003 when military-civilian radar at Ngurah Rai International Airport in Denpasar, Bali detected suspicious movement of several aircraft northwest of Bawean Island, with the altitude observed to be between 15,000 ft (4,600 m) to 35,000 ft (11,000 m) and speed of 450 kn (830 km/h).
KRI Nanggala (402), also known as Nanggala II, was one of two Cakra-class Type 209/1300 diesel-electric attack submarines of the Indonesian Navy.It sank following an implosion in April 2021.
On 30 June 2015, a Lockheed KC-130B Hercules (registration number A-1310) operated to the Indonesian Air Force with 12 crew and 110 passengers on board, crashed near a residential neighbourhood shortly after taking off from Medan, Indonesia, en route to Tanjung Pinang.
The Bendix Central Air Data Computer contains complex electromechanical mechanisms. Electrical-mechanical air data computers were developed in the early 1950s to provide a central source of airspeed, altitude, and other signals to avionic systems that needed this data.
Data from Jane's all the World's Aircraft 2006-07, Volga-Dnepr General characteristics Crew: Eight (pilot, copilot, navigator, chief flight engineer, electrical flight engineer, radio operator, two loadmasters) Capacity: 88 passengers in upper aft fuselage, or the hold can take an additional 350 pax on a palletised seating system / 150,000 kg (330,693 lb) Length: 69.1 m (226 ft 8 in) Wingspan ...
In larger aircraft, weight and balance is often expressed as a percentage of mean aerodynamic chord, or MAC. For example, assume the leading edge of the MAC is 62 inches aft of the datum. Therefore, the CG calculated above lies 32 inches aft of the leading edge of the MAC. If the MAC is 80 inches in length, the percentage of MAC is 32 / 80 = 40%.
For symmetrical airfoils =, so the aerodynamic center is at 25% of chord measured from the leading edge. But for cambered airfoils the aerodynamic center can be slightly less than 25% of the chord from the leading edge, which depends on the slope of the moment coefficient, . These results obtained are calculated using the thin airfoil theory so ...
