No, they do not, they get "bouyancy" from the speed of air around the wings.

What advantages did airplanes provide in the war?
Airplanes help nations attack from the air. Airplanes give nations a strategic advantage because they can do a lot of damage from the air.
How submarines float on water?
The air trapped in the hull (this includes the buoyancy tanks) make it lighter than the water it displaces. The buoyancy tanks surround the main hull (where the people and machinery are), and can be flooded to allow the ship to sink. Refilling them with air (from compressed air tanks) allows it to return to the surface.
Is a blimp a type of hot air balloon?
No, it is a gas balloon. It relies on lighter than air gases (helium or hydrogen) to provide buoyancy.
Why do submarines submerge?
To control its buoyancy, the submarine has ballast tanksand auxiliary, or trim tanks, that can be alternately filled with water or air. When you fill it with water, it sinks, When you first let the water out then you let the air in (from compressed air in the submarine) it floats.
HOW can a submarine float in water sink in the sea or come up to the surface?
The buoyancy of a submarine may be varied by having ballast tanks, into which either water or compressed air may be added or subtracted to vary the average density of the boat. Thus it will have a variable buoyancy.
How does a submarine floats then sinks then floats?
It is a matter of buoyancy. There are large tanks that can be filled with sea water or with air. To submerge they pump the air into compressed tanks and the water fills it up sinking the sub. When they want to go back up, they blow the water out using the compressed air.
What is the study of compressed air?
compressed air science
Which categories is usage of compressed air and gas divided into?
The three major categories of usage for compressed air and gas are: compressed air and gas for process services, compressed air for power, and compressed air for general industrial applications.
How do I control my buoyancy as I ascend after a dive?
release air from your buoyancy vest.
What are facts about buoyancy?
buoyancy has to deal with density, gravity, air, and water
What is the purpose of a compressed air dryer?
A compressed air dryer is used to remove water vapor from compressed air. Compressed air dryers are used mostly in commercial and industrial facilities.
Does airplanes sometimes stop in air?
NO, airplanes have to keep moving in the air.
