What are the curved tips on airplane wings?

These sections of an aircraft wing are called winglets. “A winglet is an additional structural component of a wing structure with the primary function of reducing wingtip vortex, which is produced due to the pressure difference between the upper and lower surface of a wing while an aircraft is moving.”

Ever wondered what those rods sticking out of the trailing edge of an aircraft wing are? Some might think they are aerials or sensors, but actually, they are a lot simpler than that. These are called static wicks, and they are fundamental to safe flying.

When flight attendants or pilots need to look at the wings, the triangle stickers act like a sign telling them exactly where to look.

If winglets are so great, why don't all airplanes have them? Because winglets are a tradeoff: In the highly visible case of the 777, an airplane with exceptionally long range, the wings grew so long that folding wingtips were offered to get into tight airport gates.

When it is used. According to the FAA, rotation refers to, When the wings are lifting the weight of the airplane off the surface. In most airplanes, this is the result of the pilot rotating the nose up to increase the angle of attack (AOA).

The nose wheel tiller is used until approximately 80 knots to keep the aircraft straight during takeoff, thereafter the rudder is used. During landing, the rudder is used until the aircraft is slowed to 80 knots, then the tiller is used once again.

Handshake – The initial interaction or 'greeting' between two computers. Aircraft communicate with satellites for location purposes. Aeronautical satellite communication (SATCOM) systems are used to transmit messages from the cockpit as well as automated messages from on-board systems.

An especially astute passenger will notice that these little triangles throughout the cabin line up with the wings outside the plane. If flight crew need to check the wings, these triangles let them know the best vantage points for the slats and flaps outside.

From a practical point, no, a modern airliner will not lose a wing due to turbulence. Modern airlines are very tough and designed to withstand extreme turbulence. In theory, it might be possible. But to my knowledge, it has not happened to any jet airliner.

The behavior of the aircraft once in the vortex can be unpredictable. Usually, due to the rotational nature of the vortex, it can cause the aircraft to roll to one side and soon after cause it to roll to the other side.

Depending on the size of the helicopter, significant wake turbulence can be generated. Helicopter wakes may be of significantly greater strength than those from fixed-wing aircraft of similar weight. The strongest wake turbulence can occur when the helicopter is operating at lower speeds (20 to 50 knots).
