Are there any DC-9 still flying?
Today, only newer versions of the 747 remain. As far as remnants of the former Douglas Aircraft Corporation are concerned, the DC-9 and DC-10 are both survived in passenger service by the iconic DC-3, a workhorse that’s been flying since 1935. Passenger versions still fly with Buffalo Airways in Canada.
What is Flex thrust?
The flex thrust/assumed temperature method employs an alternate thrust setting that is applicable to the highest ambient temperature at which the airplane could meet performance requirements at its actual takeoff weight.
How far can a DC-9 Fly?
Usual range of the aircraft with fifty passengers and baggage is 950 nautical miles rising to 1,278 nautical miles during long range flights. The DC-9-10 has a travel range of 600 nautical miles with maximum payload of 18,000 kg, and 1,450 nautical miles if flying with full fuel.
What is Flex thrust takeoff?
20. An assumed temperature takeoff (also known as “flex” on Airbus/Fokker aircraft) is where the engine thrust is reduced to match the performance on a higher-temperature day, up to either the maximum thrust reduction allowed or the maximum assumed temperature that meets takeoff distance requirements.
Do any airlines still fly 727?
Various cargo carriers in the United States still fly a handful of Boeing 727 freighters. They include USA Jet Airlines, MP Aviation, Kalitta Charters, Interjet West, Gulf and Caribbean Cargo, and Anchorage-based Everts Air Cargo. The remaining Boeing 727 operators are scattered far and wide.
Why do pilots reduce thrust after takeoff?
Pilots reduce thrust after takeoff mostly because of noise abatement procedures at the airport. Engines produce their most noise at takeoff power & to keep the local neighbor’s happy airport departure procedures call for a reduction in power from 800 feet to 3000 feet to reduce noise pollution.
Why we use derated thrust on takeoff?
Derated thrust takeoff results in a slower acceleration on the runway, a longer takeoff roll and a reduced initial climb rate.
Is DC-9 a good plane?
The DC-9 has been called the workhorse of the airline fleets because it has generally been reliable and is still flying for several airlines today. Further, its manufacturer, McDonnell Douglas, employs the same basic design in newer generation jets, including the MD-80, MD-88 and the MD-90.
Why did McDonnell Douglas fail?
Douglas dominated commercial aircraft manufacturing before WWII. Douglas failed because customers did buy its products. Douglas fell with a successful innovative product, the DC-9, and an order backlog in excess of $3 billion and growing, enough work to keep its production lines humming for years.
What is maximum continuous thrust?
Maximum continuous thrust is the most thrust an engine can produce over a long period of time. An engine can produce more thrust than the maximum continuous level, but only for a few minutes. (This is called maximum takeoff thrust, and is physically the most thrust an engine can produce.)
Where is the Boeing 777 upright build system?
The Fuselage Automated Upright Build (FAUB) system was developed and quietly tested in Anacortes, Washington, 40 miles north of the 777 Everett assembly plant. A major leap in automated production, it drills the tens of thousands of holes in the fuselage more quickly, accurately, and safely.

What kind of plane is the Boeing 717?
The Boeing 717 is a jet airliner. It has two engines, which means that it is a twinjet. It also only has two columns of seats, which makes it a narrow-body plane. The Boeing 717 was designed and sold by McDonnell Douglas. It was called the MD-95, which was designed from the DC-9. The 717 can hold up to 117 passengers.
