Definition
Continuous, electronically derived track information provided to the pilot by a navigation aid such as a VOR, localizer, GPS, or RNAV system, allowing the aircraft to be flown along a specific, defined course with measurable left/right deviation indication.
Plain English
A real, navigation-based line in the sky the pilot can follow, with an instrument showing whether the aircraft is left or right of that line. It is not just a heading to fly or a visual reference — it is an actual course signal the pilot can track.
Context Anchor
Seen in instrument departure procedure discussions, especially when explaining how a departure path is protected from obstacles.
Derivation
"Positive" here comes from the Latin positivus, meaning "definitely placed" or "firmly established" — not "good" or "affirmative." In navigation, it signals that the course is concretely defined and trackable, not assumed or estimated.
Why Pilots Care
Keeps the aircraft on a protected path away from terrain and obstacles when visibility is low.
Grounding Statement
After takeoff in low visibility, Positive Course Guidance is what tells the pilot, “This is the path to follow,” rather than leaving the turn or track to guesswork.
Intuition Check
Do not read “positive” as “good” or “encouraging” here. In this phrase, “positive” means definite, established, and usable for navigation.
Example Sentence 1
The departure procedure required positive course guidance by 1,200 feet AGL, so the pilot intercepted the localizer as soon as possible after takeoff.
Example Sentence 2
After takeoff the controller confirmed positive course guidance from the GPS waypoints before issuing further climb instructions.
