Which country has the fastest fighter jet?
The fastest fighter still in service today is the Soviet-built MiG-25..
Do planes use full throttle on takeoff?
Answer: Most takeoffs use “derated” thrust to save engine wear. For each takeoff, performance is calculated, the necessary power setting is determined and the thrust setting is made. … When using this method during takeoff, it is always possible to increase to full power if the situation requires.
What is the most dangerous part of a flight?
Boeing research shows that takeoff and landing are statistically more dangerous than any other part of a flight. 49% of all fatal accidents happen during the final descent and landing phases of the average flight, while 14% of all fatal accidents happen during takeoff and initial climb.
What is the stall speed of a 747?
Now plug in the numbers: Minimum weight for a 747–400 is 254,500 kg , and the same source gives the stall speed in landing configuration at 280 tons with 138 knots or 71 m/s. Now correct for the minimum mass and the higher density, and the result is 118 knots or 60.72 m/s. This is as low as it gets, but no longer safe.
What is the stall speed of an airplane?
Stall speed is slowest speed a plane can fly to maintain level flight. Normally, when a plane slows down it makes less lift. If the plane tilts its wings up, also known as increasing its angle of attack, it can compensate for any lift lost.
Who broke Mach 4?
It was two years later before the sound barrier was broken by an American aircraft the Bell X-1. Test pilot ‘Chuck’ Yeager named the aircraft ‘Glamorous Glennis’ after his wife.
How many hours can a 737 800 fly?
eight hoursCurrently, Boeing 737 aircraft is deployed into various routes around the world. The distance covered by the older models is much less than that of the re-engined MAX series, for example. Still, the plane can cover up to 3,600 nautical miles and stay over eight hours in the air.
What is the landing speed of a 737?
For an average-sized commercial jetliner with typical fuel and payload, the “takeoff speed” is around 130-160 knots, or about 150 to 200 miles per hour. The landing speed is more or less the same, usually a few knots slower. With a very common 737-800 the landing speed is about 180-200 knots.
Why do planes stall when flying straight up?
It stops climbing when the air density drops to the point lift on the wing is less that the aircraft weight. … If the aircraft’s power is not enough to power it above stall speed when going straight up (i.e. opposite to gravity rather than across it) then air stops flowing across the wings and it stops flying.
Does Tom Cruise actually fly a jet?
The star is actually a real pilot! Tom fell in love with aviation while filming the original Top Gun, which was released in 1986. He got his private pilot’s license in 1994 and has been active in the flying community ever since.
Why was the 747 discontinued?
The 747 democratized global air travel in the 1970s but fell behind modern twin-engine passenger jets. … In 2016, Boeing said it could end 747 production amid falling orders and pricing pressure. Major U.S. carriers like United Continental Holdings Inc and Delta Air Lines Inc have already said goodbye to the 747.
What plane has the lowest stall speed?
The WW2 Luftwaffe Fiesler Storch was reported to stall at 28 knots/32 mph. The Cessna 152 reportedly has a stall speed of 35 knots/40 mph with full flaps.
What is the temperature at 35000 feet?
The higher you get, the colder it gets, up until 40,000 feet. If the temperature at ground level was 20C, at 40,000 feet it would be -57C. At 35,000 feet the air temperature is about -54C.
How fast do planes accelerate on the runway?
If a reduced thrust takeoff is being made, the ground run may be slightly longer. An average commercial jet accelerates to between 120 and 140 knots prior to liftoff. To do this in 30 to 35 seconds requires a good sustained acceleration. This is something that pilots look for during a takeoff roll.
Has a Boeing 737 800 ever crashed?
A Boeing 737-800 operated by Lion Air crashed in the sea while attempting to land at Indonesia’s Denpasar airport in April 2013. … On 22 May 2010, Air India Express Flight 812, a Boeing 737-800, overran the runway while landing at Mangalore International Airport, killing 158 passengers, including six crew members.
What is the oldest 747 still flying?
The oldest 747 still flying ordinary punters is owned by Iran’s Mahan Air. It first flew in 1986 and has been on Mahan’s books since 2007. The majority of BA’s active jumbos are far newer. The oldest, G-BNLY, was delivered in 1993; the newest, G-BYGG, in 1999.

What is the fastest jet in the world?
Lockheed SR-71 BlackbirdThe Lockheed SR-71 Blackbird is the fastest jet aircraft in the world, reaching speeds of Mach 3.3–that’s more than 3,500 kph (2,100 mph) and almost four times as fast as the average cruising speed of a commercial airliner. Key elements of the SR-71’s design made this possible.
Why do planes stall at low speed?
At high speeds, the fast-moving air “lifts” the airplane so that it doesn’t fall to the ground. At low speeds, on the other hand, the lack of air movement will result in little or no lift being produced, in which case the airplane may stall.
What is the 747 being replaced with?
The average age of those planes is 23 years, close to the end of their expected service life. The airline’s capacity is being replaced by Airbus (AIR. France) A350 jets and Boeing (ticker: BA) 787 jets, which are about 25% more fuel efficient than the 747, according to British Airways.
