Definition
In ADF (Automatic Direction Finder) navigation, tracking is the procedure of flying a desired course to or from an NDB (non-directional beacon) by applying a wind correction angle that holds the aircraft on that course over the ground. The pilot adjusts heading so that the relative bearing to the station, combined with the heading, keeps the aircraft on the intended track despite crosswind drift.
Plain English
Tracking is staying on a chosen line over the ground to or from a radio beacon by turning slightly into the wind so the wind doesn't push you off course.
Context Anchor
Used when flying to or from a radio beacon with an automatic direction finder, especially when comparing homing with proper wind-corrected navigation.
Derivation
From 'track,' meaning the path made over the ground. In aviation, your track is the actual line you trace across the earth, which is different from your heading (where the nose points). Tracking is the active work of making the two agree with the course you want.
Why Pilots Care
Correct tracking prevents drifting off the intended course and ensures the aircraft arrives at the station or proceeds safely outbound.
Grounding Statement
With wind, the airplane may need to point slightly into the wind while its path over the ground stays straight toward or away from the beacon.
Intuition Check
Tracking does not mean simply chasing the needle or aiming straight at the beacon. It means correcting for wind so the aircraft stays on the intended ground path.
Example Sentence 1
After intercepting the inbound course, the pilot established a wind correction angle and began tracking to the NDB.
Example Sentence 2
After passing the station, a right turn and new heading allowed the aircraft to track outbound along the 180 radial.
