heavier-than-air

Spills would also be a health risk, since carbon dioxide is heavier than air, and so can build up in low-lying or poorly ventilated spots.

With a wing and one refers to one or more with the engine, relying on its own power to fly in the atmosphere heavier than air aircraft.

People called the Wright brothers mad but it did not stop them from becoming the first men to construct and fly a heavier-than-air craft.

Any of various winged vehicles capable of flight, generally heavier than air and driven by jet engines or propellers.

I say "catastrophic" because carbon dioxide is heavier than air, and a ground-hugging cloud would suffocate anyone it enveloped.

Some gases used are not necessarily toxic, but can be heavier than air, thus displacing oxygen and creating a breathing safety hazard.

Therefore, a precise definition of the aircraft is: there is a power-driven aircraft, fixed wing aircraft and is heavier than air.

But it is worth remembering that just over a century ago, heavier-than-air flight seemed an impossible dream.

That day they became the first people to demonstrate sustained flight of a heavier-than-air machine under the complete control of the pilot.

Because CO2 is 40% heavier than air, placement of exhaust vents at or near ground level is recommended when blasting in an enclosed area.

An aircraft towing objects has the right of way over all power -driven heavier - than -air aircraft.

Sometimes the craft is heavier than air, and sometimes lighter.

Under normal atmospheric conditions, carbon dioxide exists as a colorless, odorless gas which is about 1. 5 times heavier than air.

Aeroplanes shall give way to power -driven heavier - than -air aircraft.

Power -driven heavier - than -air aircraft shall give way to gliders.

Named after Samuel Pierpont Langley (1834 - 1906), American astronomer, physicist, and pioneer in the development of heavier-than-air craft.

Carbon dioxide in pure form can asphyxiate because it is heavier than air.

Cold air is heavier than air, easy to sink;
