Which term describes the technique of using atmospheric energy to stay aloft without powered flight?

• A. Balloon
• B. Burner
• C. Soaring
• D. Altimeter

Answer: (C)

Soaring is the technique of using atmospheric energy to stay aloft without engine power. It relies on rising or moving air—thermals, ridge lift, and wave lift—that gliders and birds ride to gain height and travel. By circling in thermals or riding updrafts along terrain, a pilot can stay airborne without propulsion. A balloon, meanwhile, stays aloft due to buoyancy from lighter-than-air gas rather than atmospheric energy being harnessed in flight. A burner provides heat to lift a hot air balloon, which is a powered system, not the unpowered atmospheric-energy method. An altimeter is just a device to measure altitude, not a way to stay aloft. Soaring best fits the concept.
