The field of materials engineering is an important one within aerospace engineering. Its practice is defined by the international standards bodies [1] who maintain standards for the materials and processes involved. [2] Engineers in this field may often have studied for degrees or post-graduate qualifications in it as a speciality. [3]
Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. [3] It has two major and overlapping branches: aeronautical engineering and astronautical engineering. Avionics engineering is similar, but deals with the electronics side of aerospace engineering.
Fuel fraction is a key parameter in determining an aircraft's range, the distance it can fly without refueling. Breguet ’s aircraft range equation describes the relationship of range with airspeed , lift-to-drag ratio , specific fuel consumption , and the part of the total fuel fraction available for cruise, also known as the cruise fuel ...
It belongs to the class of altitude compensating nozzle engines. A vehicle with an aerospike engine uses 25–30% less fuel at low altitudes, where most missions have the greatest need for thrust. Aerostat – is a lighter than air aircraft that gains its lift through the use of a buoyant gas.
The APUs on aircraft such as the Boeing 737 and Airbus A320 can be seen at the extreme rear of the aircraft. This is the typical location for an APU on most commercial airliners although some may be within the wing root ( Boeing 727 ) or the aft fuselage ( DC-9 / MD80 ) as examples and some military transports carry their APUs in one of the ...
The FBISE was established under the FBISE Act 1975. [2] It is an autonomous body of working under the Ministry of Federal Education and Professional Training. [3] The official website of FBISE was launched on June 7, 2001, and was inaugurated by Mrs. Zobaida Jalal, the Minister for Education [4] The first-ever online result of FBISE was announced on 18 August 2001.

In an emergency, an aircraft may choose to land overweight, but this may damage it, and at the very least an overweight landing will mandate a thorough inspection to check for any damage. In some cases, an aircraft may take off overweight deliberately. An example might be an aircraft being ferried over a very long distance with extra fuel aboard.
