What is the fastest fighter jet in the world?
The fastest fighter still in service today is the Soviet-built MiG-25.
Mikoyan designed this fighter to be a pure interceptor aircraft.
As a result, the Foxbat can sustain a cruising speed of Mach 2.8 and kick it into overdrive with a top speed of 3.2 — not a bad technology for an aircraft that first took off in 1964..
What is the fastest jet in the world?
North American X-15Number 1: North American X-15 This aircraft has the current world record for the fastest manned aircraft. Its maximum speed was Mach 6.70 (about 7,200 km/h) which it attained on the 3rd of October 1967 thanks to its pilot William J. “Pete” Knight.
Why do pilots reduce thrust after takeoff?
After climbing enough altitude pilot reduces aircraft engine power. … And aircraft engines produce really very loud noise. That loud noise can be irritating for residents. To reduce that noise problem, at an altitude between 1000ft (0.3048Km) to 1500ft (0.4572Km) above ground level pilots reduce engine power.
Why do pilots say rotate when they take off?
Pilots say rotate because it is a verbal queue that an airplane has reached its predetermined rotation speed (frequently abbreviated to Vr). This is the speed at which control inputs can be applied to lift the nose off the runway and make the airplane fly away.
Why do aircraft 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 do pilots say heavy?
The word “heavy” means a larger aircraft type, with a Maximum Takeoff Weight of 160 tonnes or more. These aircraft create wake turbulence from their wings and require extra separation between following aircraft, and the use of “heavy” reminds other pilots of that fact.
Why do pilots say v1?
A: V1 is the speed by which a pilot must have decided to abort if they are going to stop on the runway. Pilots calculate this value by the runway length, obstacles, temperature, runway slope and the weight of the airplane. The airplane manufacturer provides these performance figures determined during flight testing.
What happens if you fall from 30000 feet?
Falling from 30,000 feet, you’re likely to reach terminal velocity at 190 km (118 miles) per hour. Of course, your actual terminal velocity will depend on your size and weight. The heavier you are, the faster you’ll fall. But if you spread your arms and legs out wide, you can increase the amount of drag exerted on you.
Do planes use full throttle on takeoff?
For example, small piston engine airplanes use full power for takeoff as a rule. … But jet airliners may use less than full power, but enough power for a safe takeoff. This is known as “flex” thrust, or “assumed temperature”. Boeing aircraft have a system which reduces takeoff thrust by a certain percentage.

How fast is a 747 going at takeoff?
Speeds vary according to performance, environmental conditions and weight but typically a fully loaded 747 on a normal long haul flight would take off from a typical length runway at around 160 knots which is 184 mph.
What does v1 mean on take off?
critical engine failure speedV1 is the Decision speed (sometimes referred to as critical engine speed or critical engine failure speed) by which any decision to reject a takeoff must be made. Above V1, the takeoff must be continued unless there is reason to believe that the aircraft will not fly.
What is the slowest a plane can fly?
Aeroplanes, or airplanes if you’re American, need to maintain a certain speed to allow flight. 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).
Why is take off dangerous?
Why airplane takeoffs and landings are so dangerous. Boeing research shows that takeoff and landing are statistically more dangerous than any other part of a flight. … During takeoff and landing, pilots have less time to react to problems because they’re on or close to the ground and moving quickly.
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.
Why do pilots say Niner?
The reason for these somewhat strange pronunciations is to encourage the pilot/controller to enunciate clearly, so that the numbers are clearly understood. … The reason for “Niner” is that “Nine” can be easily muffled, slurred, or confused with other words (particularly the number Five/Fife).
What do pilots say before taking off?
ATC will either say “Expedite Departure” or “No Delay” to let the aircraft know to get it in gear and take off immediately. A radio call from ATC would go something like this: ATC: “Cessna 128DP, cleared for take off, runway 16, no delay, straight out departure approved”
What does squawk 7777 mean?
§ military interception§ military interception (US) (“Under no circumstances should a pilot of a civil aircraft operate the transponder on Code 7777. This code is reserved for military interceptor operations.”) § non-discrete code used by fixed test transponders (RABMs) to check correctness of radar stations (BITE).
