What is described as a "Dive" in aviation terms?

In aviation, a "Dive" specifically refers to a steep descent that an aircraft may undertake. This term is typically used to describe a situation where the aircraft descends at a significant angle, which can be necessary for a variety of operational reasons, such as maneuvering during an emergency or preparing for a landing.

The steep descent allows pilots to lose altitude quickly and efficiently, which can be crucial in certain scenarios. Understanding this terminology is vital for flight attendants, as it may pertain to safety procedures or emergency responses during flight operations.

The other options do not accurately reflect the concept of a "Dive." A gradual descent from cruising altitude is simply a normal descent process, while a maneuver for gaining altitude contradicts the idea of descending altogether. A sudden stop of the aircraft is more related to a braking scenario rather than a technical descent maneuver.
