The main landing gear is a 6-wheel bogie instead of a 4-wheel bogie, put in a one frame longer bay. The Rolls-Royce Trent XWB engine's thrust is augmented to 97,000 lbf (430 kN). [251] These and other engineering upgrades are necessary so that the −1000 model maintains range. [252] Qatar Airways was the A350-1000 XWB launch operator in ...
Cropped delta – tip is cut off. This helps maintain lift outboard and reduce wingtip flow separation (stalling) at high angles of attack. Most deltas are cropped to at least some degree. In the compound delta, double delta or cranked arrow, the leading edge is not straight. Typically the inboard section has increased sweepback, creating a ...
Delta-v (also known as "change in velocity"), symbolized as and pronounced deltah-vee, as used in spacecraft flight dynamics, is a measure of the impulse per unit of spacecraft mass that is needed to perform a maneuver such as launching from or landing on a planet or moon, or an in-space orbital maneuver.
The F-106 was the ultimate development of the USAF's 1954 interceptor program of the early 1950s. [4] The initial winner of this competition had been the F-102 Delta Dagger, but early versions of this aircraft had demonstrated extremely poor performance, being limited to flying at subsonic speeds and relatively low altitudes.

Delta Air Lines Flight 191 was a regularly scheduled Delta Air Lines domestic service from Fort Lauderdale, Florida, to Los Angeles, California, with an intermediate stop at Dallas/Fort Worth International Airport (DFW).
Since 2013, Delta has been working to reduce the age of its fleet by purchasing or leasing newly built aircraft or newer model used aircraft. Since launching the effort, Delta has preferred to purchase aircraft from Airbus, a major change for the company which had been a loyal customer of Boeing and McDonnell Douglas (which merged with Boeing in 1997).
Exploration Flight Test-1 or EFT-1 (previously known as Orion Flight Test 1 or OFT-1) was the first test flight of the crew module portion of the Orion Multi-Purpose Crew Vehicle.
A belly landing or gear-up landing occurs when an aircraft lands without its landing gear fully extended and uses its underside, or belly, as its primary landing device. Normally the term gear-up landing refers to incidents in which the pilot forgets to extend the landing gear, while belly landing refers to incidents where a mechanical ...
