How many knots does a Boeing 747 need to take off?
How many knots does a Boeing 747 need to take off? How Fast Does a 747 Go To Take Off? A typical takeoff speed for a Boeing 747 is around 160 knots (184 mph), depending on the jet's wing flap configuration, the number of passengers aboard, and the weight of their luggage, fuel load, current weather conditions, and other factors.
Why do aircraft fly at 35000 feet?
The biggest reason for flying at higher altitudes lies in fuel efficiency. The thin air creates less drag on the aircraft, which means the plane can use less fuel in order to maintain speed. Less wind resistance, more power, less effort, so to speak.
Why do planes not fly over Tibet?
Emergency landings are tough at high altitudes High terrain can cause a plane to crash if the cabin depressurizes, the plane must descend to 10,000 feet before heading to a nearby airport. Airlines choose not to fly over Tibet to prevent such situations.
How many hours can a 747 fly?
This depends on the size of the plane, its efficiency, and how fast it's flying. A modern Boeing 747 can fly about 15,000 km (9,500 miles) when it's flying at 900 kmh (550 mph). This means it can fly non stop for almost 16 hours!
Can a 747 fly on one engine?
The Boeing 747 is a four-engine wide-body jet airliner that has been in service since 1970. It is one of the most recognizable and iconic aircraft in the world, and has earned the nickname “Queen of the Skies”. The Boeing 747 can fly on one engine only, but it is not recommended or desirable to do so.
What speed does a 747 cruise at?
On average, the typical cruising speed of a large commercial aircraft, like a Boeing 747, is somewhere between 475 and 500 knots (roughly 575 mph). So what is the cruising speed of a 747? Depending on passenger load, the average cruise speed of a 747 is 490 nautical miles or Mach 0.85.
What is the takeoff speed of a 747?
A typical takeoff speed for a Boeing 747 is around 160 knots (184 mph), depending on the jet's wing flap configuration, the number of passengers aboard, and the weight of their luggage, fuel load, current weather conditions, and other factors.
Is the 747 underpowered?
Underpowered and heavy The increased MTOW also led to problems for engine supplier Pratt& Whitney (P&W). Its innovative JT9D engine was designed to produce 41,000lb of thrust but would now need to generate an additional 1,000lb to propel the heavier 747 into the air.
Why do pilots reject takeoff?
A takeoff may be rejected for a variety of reasons, including engine failure, activation of the takeoff warning horn, direction from air traffic control (ATC), blown tires, or system warnings.
How long can a 747 fly without engines?
How long can a 747 fly without engines? For example, with a glide ratio of 15:1, a Boeing 747-200 can glide for 150 kilometres (93 mi; 81 nmi) from a cruising altitude of 10,000 metres (33,000 ft).
Can you buy a retired 747?
Sure, the 747 is a Type Certified and airworthy aircraft, the FAA does not really care who owns it so long as they play by the rules. Boeing even sells them directly to the private market via their BBJ line. There are even a few used ones listed for sale right now.
Can a pilot abort a takeoff?
Depending on Operator SOPs, a call of STOP (ABORT', REJECT) to reject a takeoff, based on stated criteria, will usually be able to be made by either pilot. However, in some cases, the actions following such a call will be only for the pilot in command to take, regardless of which pilot is PF.
