Do pilots turn off engines?
Pilots have come out and said that while we’re in the air eating our boxed dinner or packaged snack, they turn the engines off.
It also means that if there is an emergency situation and the engines do fail, flight crews have time to solve the issue.
Has a propeller plane broke the sound barrier?
Originally Answered: Has a propeller-driven aircraft ever broken the sound barrier? Yes. It was NASA’s XF-88 research aircraft, which had a specially designed prop to complete the task, and landed safely.
Can planes stop in the air?
No a plane doesn’t stop in midair, planes need to keep moving forward to remain in the air (unless they are VTOL capable). What it can do is simply turn around or go over/under the obstruction. VTOL means vertical takeoff and landing. It essentially means they can hover in place like a helicopter.
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.
How cold is it at 35000 feet?
How cold is it up there? 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.
Why do planes fly at 35000 feet?
The “sweet spot” of flying is regarded as between 35,000 and 42,000 feet – too high and the oxygen becomes too sparse to fuel the engines, too low and the air resistance is greater. This optimum height is linked to the usual weight of a commercial jet – that is, heavier planes fly lower, and lighter higher.
Why are there no 747 planes?
Boeing is ending the 747 production line in 2022 while Airbus just delivered its last A380 fuselage to the assembly line in France in June. High operating costs and efficient twin-engine alternatives marred orders for both planes in the 2010s as the manufacturers promised jets that could fly further for cheaper.
How do female fighter pilots pee?
The female version has a pad-like receptacle that fits under the flight suit. Both versions then feed urine to a disposal bag strapped to the leg.
What is the cruising speed of a 747?
The top speed for a 747 is about 570 miles per hour (mph), and this flight topped out at 825 mph.
What is the normal cruising speed of a 737?
The 737-800 incorporates an advanced-technology wing design that helps increase fuel capacity and efficiency, both of which increase range. The advanced wing airfoil design provides an economical cruise speed of . 789 Mach (530 mph) – compared to . 745 Mach for earlier 737 models.
What’s 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.
What’s better f22 or f35?
While the F-22 is superior to the F-35 in air-to-air missions, the F-35’s air-to-air capability is superior to all other fighters. The F-35 is better than any other fighter aircraft, including the F-22, for air-to-ground strike missions.
What is the slowest a plane can fly?
Technically this is the so-called ‘stall speed’, where air passes over the wings fast enough to sustain altitude, and for small planes this can be less than 50km/h (31mph). But at such low speeds, the aircraft is easily destabilised, and could fail to leave the runway.
Do airplanes have speed limits?
Ask the Captain: Is there a speed limit for planes taxiing on the ground? Question: Is there a speed limit for planes while taxiing on the taxiway? Answer: Some airports have speed limits but more often airplanes will have a limitation in the flight manual for maximum taxi speeds. This is usually around 30 knots.
Why do pilots reduce thrust after takeoff?
Answer: The sensation of slowing down is really one of slowing the rate of acceleration; this is due to reducing the thrust after takeoff to the climb setting. The sensation of “dropping” comes from the retraction of the flaps and slats. The rate of climb is reduced, causing it to feel like a descent.
Are 747 still being built?
US airplane manufacturer Boeing will cease production of its 747 jumbo jet in 2022, the company announced on Wednesday, retiring the iconic passenger aircraft after over 50 years of service amid a coronavirus-induced crisis in the aviation industry.
What happens to v1 on a wet runway?
When a wet runway is considered a VEF (about 10kts lower than before) is used with a correspondingly lower V1, called V1 WET. The idea of reducing the V1 is to improve the chances of stopping. However if the decision is to “GO”, then reducing the V1 increase the TOD (i.e. accelerating with a failed engine).
Will Draco fly again?
Mike Patey announces major restoration of turbine Wilga after devastating crash. Mike Patey, who crashed the bright red taildragger on departure after the Stihl National Championship Air Races in Reno this fall, has announced that he is working on a major restoration of the airplane. …
What speed do planes land at?
Big commercial airplanes generally fly in the 550-580 MPH range, but their landing and taking-off speeds are naturally going to be different. Most commercial planes take off at roughly 160 to 180 MPH, while landings take place at approximately 150 to 165 MPH.
Which country has the most powerful fighter jet?

Do planes fly in the jet stream?
What is a jet stream? Jet streams are strong westerly winds that blow in a narrow band in the Earth’s upper atmosphere – at the altitudes used by most aircraft. … By flying in a jet stream, aircraft travelling from west to east get carried along by the tailwind, saving them time – and/or fuel.
What is the fastest a 737 can fly?
In addition to the 801 mph ground speed clocked Monday, several other notably high speeds were recorded. An LAX-JFK Delta flight Monday night hit a ground speed of 678 mph at 39,000 feet over the Ohio Valley, while a 737 from Chicago to New York passed 700 mph at 8:43 Eastern Tuesday morning.
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.
