Definition
A descending flight path with a small downward angle relative to the horizon, used to gain airspeed or lose altitude gradually while keeping the aircraft well within normal operating limits.
Plain English
A gentle nose-down descent — just enough to pick up speed or lose height slowly, not a steep plunge.
Context Anchor
Seen in chandelle training, where a pilot may enter the maneuver from a slight nose-down descent to gain or maintain the proper entry speed.
Derivation
Shallow means not deep or not steep. Dive originally meant to plunge downward, but in aviation it can also mean a controlled nose-down flight path, not only a sudden or extreme drop.
Why Pilots Care
Allows safe acceleration to maneuvering speed before starting a climb turn without building excessive speed or losing too much altitude.
Grounding Statement
Picture easing the nose forward just enough for the airspeed to rise steadily while the horizon stays mostly in view.
Intuition Check
Do not read dive here as an emergency plunge. In this context, a shallow dive means a deliberate, mild nose-down descent.
Example Sentence 1
The pilot entered a shallow dive to gain a few knots of airspeed before pulling up into the chandelle.
Example Sentence 2
Maintain a shallow dive during the rollout so the airplane does not overspeed before leveling off.
