What do you need to make a plane fly?
Airplane wings are shaped to make air move faster over the top of the wing. When air moves faster, the pressure of the air decreases. So the pressure on the top of the wing is less than the pressure on the bottom of the wing. The difference in pressure creates a force on the wing that lifts the wing up into the air.
How do things fly?
The first force, lift, pushes up on things that fly — airplanes, birds, helicopters and rockets. The shape of the wings on an airplane and the whirling blades of a helicopter create lift as they move through the air. Birds create thrust (and lift!) with their wings. Thrust pushes things that are flying.
Is Boeing 777 fly by wire?
The Boeing 777 is a formidable flying machine. Its Fly-By-Wire Flight Control System greatly enhances aircraft handling qualities, increases safety and reliability, reduces system weight and maintenance costs and lets the pilots have ultimate full authority over the ship at all times.
What happens if Fly-By-Wire fails?
In case of electrical failure, as long as hydraulics are OK, the pilot should be able to control the aircraft. Some fly-by-wire aircrafts are unstable by design. In these cases, any power loss will lead to loss of control and crash.
How many 777 crashed?
As of February 2021, the 777 had been involved in 31 aviation accidents and incidents, including seven hull losses (five during flight and two on the ground) with 541 fatalities, and three hijackings.
Is Fly-By-Wire safe?
True, there have been accidents and incidents involving fly-by-wire airplanes. In 1988 an A320 crashed during its first public demonstration flight at the Mulhouse, France, airport.
Can Fly-By-Wire be hacked?
Q: Do you believe the airlines really can lock hackers out of taking over fully fly-by-wire airplanes? It is not possible to get into the flight control computers via the Internet.
What does fly-by-wire mean?
Fly-by-wire (FBW) systems are semi-automatic, computer-regulated aircraft flight control systems that replace mechanical flight controls with an electronic interface. Their “hands on” design gives pilots a direct, tactile feel for how the aircraft is handling aerodynamic forces as they fly.
Is the Boeing 787 fly-by-wire?
The 787 Dreamliner family features an advanced fly-by-wire flight control system. Instead of a mechanical system of cables and pulleys that move the control surfaces on the wing and tail, fly-by-wire systems translate pilot inputs into electrical signals.
How far can a 787-10 fly?
6,430 nautical miles
Is Boeing 777 or 787 better?
The Boeing 777 series is generally larger than the 787 and thus can carry more passengers. The 787-10 has a higher capacity than the smaller 777-200 series. However, it falls short of the larger 777-300 models by 66 passengers in a typical two-class configuration.
Are all 787 Dreamliners?
The Boeing 787 is a well-known widebody aircraft. Called the “Dreamliner,” the aircraft made quite a splash with its first flight back in December 2009. However, only three airlines operate all three variants. …
Are Boeing 787 still grounded?
8 grounded Boeing 787s were built last year; more jets may need reworking. The eight in-service 787 Dreamliner jets that Boeing grounded last month for inspection and repair due to manufacturing quality flaws at its South Carolina plant were from a batch that came off the production line more than a year ago.
How far can the 787 Dreamliner fly?
The stretched 787-9, 206 ft (63 m) long, can fly 7,635 nmi (14,140 km) with 290 passengers; it entered service on August 7, 2014, with ANA. The further stretched 787-10, 224 ft (68 m) long, seating 330 over 6,430 nmi (11,910 km), entered service with Singapore Airlines on April 3, 2018.
