Fuel Dumping
Fuel dumping (or a fuel jettison) is a procedure used by aircraft in certain emergency situations before a return to the airport shortly after takeoff, or before landing short of the intended destination (emergency landing) to reduce the aircraft's weight. Aircraft fuel dump Weight issues Aircraft have two main types of weight limits: the maximum takeoff weight is composed of DOW (Dry Operating Weight) plus Payload (passengers and cargo), collectively the ZFW (Zero Fuel Weight), plus the trip fuel, contingency, alternate, final reserve and the block fuel (taxi fuel), and the maximum structural landing weight, with the maximum structural landing weight almost always being the lower of the two. This allows an aircraft on a normal, routine flight to take off at a higher weight, consume fuel en route, and arrive at a lower weight. It is an abnormal, non-routine flight where landing weight can be a problem. If a flight takes off at the maximum takeoff weight and then must land w ...

Ground Stop
A ground stop is an air traffic control procedure that requires all aircraft that fit certain criteria to remain on the ground. This could be airport-specific or perhaps equipment- or airspace-specific, depending on the exact event that caused the ground stop to occur. Downstream effects can occur from a ground stop. It causes flights to be delayed or canceled and planes and flight crew to be unable to reach the location of their next scheduled flight. Description A ground stop is an air traffic control measure that slows or halts the flow of aircraft that meet certain criteria, requiring all aircraft of a certain criteria to remain on the ground. Often, the criteria are aircraft inbound to a given airport, where a ground stop is the halting of departing aircraft destined for one particular airport or for a specific geographic area. The criteria could be airport-specific or perhaps equipment- or airspace-specific, depending on the exact event that caused the ground stop to occ ...

DC-9
The McDonnell Douglas DC-9 is an American five-abreast, single-aisle aircraft designed by the Douglas Aircraft Company. It was initially produced as the Douglas DC-9 prior to August 1967, after which point the company had merged with McDonnell Aircraft to become McDonnell Douglas. Following the introduction of its first jetliner, the high-capacity DC-8, in 1959, Douglas was interested in producing an aircraft suited to smaller routes. As early as 1958, design studies were conducted; approval for the DC-9, a smaller all-new jetliner, came on April 8, 1963. The DC-9-10 first flew on February 25, 1965, and gained its type certificate on November 23, to enter service with Delta Air Lines on December 8. The DC-9 is powered by two rear-mounted Pratt & Whitney JT8D low-bypass turbofan engines under a T-tail for a cleaner wing aerodynamic. It has a two-person flight deck and built-in airstairs to better suit smaller airports. The aircraft was capable of taking off from 5,000 ft runw ...

MQ-9 Reaper
The General Atomics MQ-9 Reaper (sometimes called Predator B) is an unmanned aerial vehicle (UAV, one component of an unmanned aircraft system (UAS)) capable of remotely controlled or autonomous flight operations, developed by General Atomics Aeronautical Systems (GA-ASI) primarily for the United States Air Force (USAF). The MQ-9 and other UAVs are referred to as Remotely Piloted Vehicles/Aircraft (RPV/RPA) by the USAF to indicate ground control by humans. The MQ-9 is a larger, heavier, more capable aircraft than the earlier General Atomics MQ-1 Predator and can be controlled by the same ground systems. The Reaper has a 950- shaft-horsepower (712 kW) turboprop engine (compared to the Predator's piston engine). The greater power allows the Reaper to carry 15 times more ordnance payload and cruise at about three times the speed of the MQ-1. The aircraft is monitored and controlled, including weapons employment, by aircrew in the Ground Control Station (GCS). The MQ-9 ...

Su-27
The Sukhoi Su-27 (; NATO reporting name: Flanker) is a Soviet-origin twin-engine supersonic supermaneuverable fighter aircraft designed by Sukhoi. It was intended as a direct competitor for the large US fourth-generation jet fighters such as the Grumman F-14 Tomcat and McDonnell Douglas F-15 Eagle, with range, heavy aircraft ordnance, sophisticated avionics and high maneuverability. The Su-27 was designed for air superiority missions, and subsequent variants are able to perform almost all aerial warfare operations. It was designed with the Mikoyan MiG-29 as its complement. The Su-27 entered service with the Soviet Air Forces in 1985. The primary role was long range air defence against American SAC Rockwell B-1B Lancer and Boeing B-52G and H Stratofortress bombers, protecting the Soviet coast from aircraft carriers and flying long range fighter escort for Soviet heavy bombers such as the Tupolev Tu-95, Tupolev Tu-22M and Tupolev Tu-160.
