What is forward flight?

Forward Flight. While in forward flight, the tip-path plane is tilted forward, thus tilting the total lift-thrust force forward from the vertical. This resultant lift-thrust force can be resolved into two components—lift acting vertically upward and thrust acting horizontally in the direction of flight.

What makes a helicopter go forward?

Thrust, like lift, is generated by the rotation of the main rotor disk. In a helicopter, thrust can be forward, rearward, sideward, or vertical. The resultant lift and thrust determines the direction of movement of the helicopter.

What must be generated to transition from a hover to forward flight?

Translational thrust occurs when the tail rotor becomes more aerodynamically efficient during the transition from hover to forward flight.

Can helicopters fly in reverse?

A helicopter can take off or land without a runway. It can turn in the air in ways airplanes cannot. Unlike an airplane, a helicopter can fly backwards or sideways.

What does forward flight mean?

Forward flight in a helicopter means that the the horizontal component of lift is forward of vertical, and no turning component is present. Contrast to turning flight. Straight flight is forward flight, with the yaw string centered. Contrast to a slip or a skid, or sidways or backwards flight.

Forward Flight Performance - Helicopter Dynamics

Can you move forward a flight?

If you need to change your flight dates, destinations, or times, your ticket must be reissued. In some cases, airlines will charge a fee for exchanging a ticket.

Can they move your flight forward?

Yes. They have the power to switch your arrival, layover, and departure airports for a variety of reasons. If it happens to you (and if you travel enough, it likely will), don't get flustered and make a bad move—like panic-booking a last-minute flight on another airline for top dollar.

Do pilots put engines in reverse when landing?

Although most airlines deploy thrust reversers on every landing, the level of reverse thrust used is left to the pilots discretion. Most airlines instruct their pilots to put the reverser into idle reverse whether he intends to use the reverser or not. as to minimize the amount of wheel braking required.

Why can't helicopters fly as high as planes?

As the helicopter climbs in altitude, the air gets thinner, requiring the blades to work harder to generate the same amount of lift. Most helicopter pilots consider 10,000 feet the upper limit of the ideal altitude for flying.

What's harder to fly a plane or a helicopter?

Helicopters are generally more difficult to operate as compared to aeroplanes and are thus more expensive to learn how to fly. However, there are many benefits to helicopter flying.

Can a helicopter fly at 90 degrees?

No. A helicopter cannot fly 90 degrees on its side like that. That's crazy.

What does ETL stand for in helicopter?

As forward airspeed increases, the helicopter goes through effective translational lift (ETL) at about 16 to 24 knots. This is known as the ETL speed. Above this speed, the rotor system completely outruns the recirculation of old vortices and begins to work in undisturbed air.

Why do helicopter blades feather?

The horizontal hinge, called the flapping hinge, allows the blade to move up and down. This movement is called flapping and is designed to compensate for dissymmetry of lift. The flapping hinge may be located at varying distances from the rotor hub, and there may be more than one hinge.

Why do people crouch when leaving a helicopter?

It is good practice to crouch while exiting the helicopter if the rotors are turning. Many helicopter rotor systems can dip well below 6 feet from the ground level, which can potentially contact a person or object on the ground.

What is the hardest thing to do in a helicopter?

One of the most difficult helicopter maneuvers is hovering and it's often one of the first things a flight student is taught to do. Learning to hover can take a while, up to a couple of hours, but once a student learns to hover, he or she can move on to learn more advanced techniques.

Why do people crouch when entering a helicopter?

Never approach or leave a helicopter when its engine and rotors are running down or starting up. Crouch while walking for extra rotor clearance. Secure any loose articles such as hats and ensure your pockets are zipped up. Never reach up or chase after anything that blows away.

Why can't helicopters go up on Mount Everest?

Air pressure/density and oxygen levels

The top of Mount Everest is one-third of the sea level's atmospheric pressure. This level of air pressure is not convenient for helicopters to handle. The oxygen levels at the Everest base camp itself are at a 50% drop. The further up you go, the oxygen levels keep decreasing.

Can a helicopter fly up to Mount Everest?

Helicopters with turbine engine can fly around 25,000 feet high. The first helicopter landing on Everest summit though has overcome the entire issues but yet has failed in filling up some points due to the height of Everest. Thus its take off has been recorded to be the best and the highest ever grabbed.

Why can't helicopters rescue people on Mount Everest?

The air is just too thin for most helicopters to generate enough lift to remain airborne. If the helicopter is equipped to reach that height, making the landing is still an incredibly delicate affair.

Why is there a tiny hole in airplane windows?

These tiny holes, also called breather holes, serve as a safety function, by making sure that the outer pane bears all the air pressure (the pressure inside the cabin is much higher than outside). This also ensures that in case the pressure difference becomes high enough, it is the outer pane that breaks off first.

What do pilots do when both engines fail?

If all of an airplane's engines fail simultaneously, the pilot will perform an emergency landing. As the airplane descends and decelerates, the pilot will begin to search for a safe area to perform an emergency landing. Ideally, the pilot will land on a nearby landing.

Why are jet engines flat on the bottom?

Subsequently, the engines on future 737s were flattened along the bottom. This allowed them to contain a larger fan and turbine without compromising on ground clearance. The solution was not perfect, as it did have certain negative aerodynamic properties, causing more drag than a round engine.

Does Air Canada allow flight changes?

You can rebook to a different flight at no charge within 5 days from your scheduled departure. Call us at 1-888-247-2262 and our specialists would be happy to assist you (for international and other numbers, visit aircanada.com/othernumbers).

Can an airplane stay up in the air without moving forward?

Techincally, there is only one way for the aircraft to remain hanging motionless in the air: if weight and lift cancel each other out perfectly, and at the same time thrust and drag cancel each other out too. But this is incredibly rare. To stay in the air and sustain its flight, an aircraft needs to be moving forward.

How many hours can an airline change your flight?

There is no specific limit to how much the airline can change your flight time.
