Definition
A specific airborne navigation computer (the GS-200) that is part of the LABS (Low Altitude Bombing System) family of equipment. In FAA documentation, LABSC appears as a contraction used to identify this particular onboard computing unit, historically associated with military aircraft systems but listed in the FAA acronym reference for completeness.
Plain English
A name for a particular onboard navigation computer, the GS-200, used in the LABS equipment family. The acronym is just a shorthand label.
Context Anchor
Seen in FAA acronym, abbreviation, and NOTAM contraction lists when a notice or reference needs to name this specific equipment.
Derivation
LABS originally stood for Low Altitude Bombing System, a military delivery method developed in the 1950s. GS-200 is the model designation of one of the computers used within that system. The 'C' in LABSC simply marks it as the computer component.
Why Pilots Care
A pilot reading a notice should recognize LABSC as an equipment reference, not as an instruction, route, weather condition, or airspace restriction by itself.
Intuition Check
Do not read the GS in LABS GS-200 as automatically meaning glide slope here. In this contraction, GS-200 is part of the computer’s equipment name.
Example Sentence 1
While reviewing the FAA acronym list, the student noted LABSC as the LABS GS-200 computer and moved on, recognizing it was not relevant to civilian flight training.
Example Sentence 2
Technicians verified the output from the LABS GS-200 computer during preflight checks.
