The FAA is very specific to categorize lighter than air vehicles as a separate type of aircraft because of the way they handle and perform.
Lighter than air vehicles are very slow and difficult to maneuver. Indeed most hot-air balloons have no method at all to control steering or velocity, the pilot only controls the vehicle on the up/down axis. As a result lighter-than-air vehicles must always have the right-of-way over all other types of aircraft.
Additionally, pilots of lighter-than-air vehicles must be very cautious not to enter congested airspace without prior permission because of the danger they can pose to other airspace users.
One is lighter and the other one is heavier. :D
one is lither
Just, simply, Lighter than Air Vehicles are lighter than air, so that makes them fly, and Heavier than air vehicles are heavier than air, but they use airfoils on the wings to fly.
Heavier than air vehicles, such as jet airplanes, are heavy and cannot easily float without propulsion. Lighter than air vehicles, such as a glider, are light enough to glide without propulsion Lighter-than-Air vehcicles means that the vehicle gets its Lift from its bouyancy. Regular aircraft get their lift from the wings due to its forward motion through the air. Gliders do not have propulsion but their wings are very long and produce enough lift to keep them flying.
Lighter than air vehicles are vehicles which fly by reducing their overall weight to zero or near zero. This is done by using a large envelope or balloon filled with a lighter-than-air gas such as helium or hot air to lift the vehicle.
No. Aluminum is much lighter than titanium, and the lighter the aircraft, the more efficient it is. Boeing's new aircraft, the 787, is switching to carbon fiber though. This will probably be the material used in future aircraft.
they are heavier than air hence why they don't fly unless in motion.
"Lighter than air" aircraft are lighter than air! The most common are blimps. They do not rely on wings to generate lift. They contain a lighter than air gas (ex:helium) that lifts the craft into the air when ties to the ground are released. "Heavier than air" aircraft are the opposite. They rely on wings to generate lift to get into the air. Common heavier than air aircraft are general airplanes you see in the sky everyday.
in German its leichtgewicht
When an aircraft's engines are running, you must not park closer than 25 feet in front or 200 to the rear
