When u make a left/right turn in a helicopter, does it descend a lot like the plane does or is it more level?

When you turn to the left or to the right when in a helicopter, does the helicopter descend a lot like an airplane does, or not too much? Is it more a straight turn than it is with a plane? What's it like?When u make a left/right turn in a helicopter, does it descend a lot like the plane does or is it more level?it will descend in a turn because it flies using the same forces of lift thrust weight and drag



if you start off without climbing or descending and decide to bank the helicopter using a constant power setting. the force of lift that was opposing the weight of the helicopter is now tilted, you have the same amount of lift, but now a portion of it is being used to turn the helicopter and you don't have as much lift acting against the weight of the helicopter.



now this is a completely different story if you are in a hover and decide to yaw the helicopter because it uses the tail rotor to turn and it will just rotate around its axisWhen u make a left/right turn in a helicopter, does it descend a lot like the plane does or is it more level?Typically in a helicopter, in straight and level flight, the pilot isn't pulling all available power. The amount of bank will determine if there is any loss of altitude during the maneuver. The Lift being produced by the helicopter gets turned in the direction of the bank and the amount of lift created will be reduced because you have an increase in the weight or G-Force of the helicopter. 1 G is one unit of gravity, meaning whatever the helicopter weighs will be how much weight is opposing lift. When in a turn, depending on the turn the G Force increases due to weight working with centrifugal force. In banks of say, 45degrees, the load factor on the helicopter is 1.5 so a helicopter that weighs 1000lbs will have to create enough lift as if the helicopter was actually 1500lbs. That's where the available power comes in, a pilot can do these turns, without losing altitude, but they will have to pull more power in order to stay at that altitude. Fortunately helicopters are pretty rugged, and can handle sharp turns and banks. I've personally been in a 75 degree banks in a helicopter to circle down to a landing spot directly below the aircraft. In the sharp turns, especially sharp turns in an auto-rotation, you'll feel the G- Force on your body, they call it flying by the seat of your pants because you'll feel your own weight push you up and down into your seat, just like the climb and descent of a roller coaster.When u make a left/right turn in a helicopter, does it descend a lot like the plane does or is it more level?No, using the collective control you can not only maintain a steady altitude but you can also ascend or descend, depending on what you'd like to do. Depending on how steep the turn is you can get pretty "sideways". The experience overall is pretty simple and fun, then again everything in a helicopter is fun.When u make a left/right turn in a helicopter, does it descend a lot like the plane does or is it more level?
A helicopter will maintain its altitude with simple turns. The tail propeller will speed up or slow down to make the helicopter change direction. A turn during significant forward motion will cause a decrease in altitude as the helicopter banks.
