Quality] - Vrsl [extra

This is not an ICAO-standard term (ICAO uses “VFR separation” without the “L” usually). If you see “VRSL” in an ATC manual, verify the local supplement. More commonly, you’ll encounter VFR separation minima (e.g., 500 ft vertically or 1.5 km laterally below FL100). 2. VRSL in Engineering / Electronics: Voltage Reference Source Low In circuit design, VRSL can appear in documentation as an abbreviation for a low-voltage reference source – a stable voltage used to calibrate ADCs, DACs, or comparators.

The acronym VRSL is not widely standardized, but it appears in a few specific fields. Below are the most likely meanings, along with guidance on which one fits your situation. 1. VRSL in Aviation: VFR Required Separation Lateral In air traffic control (especially in some non-US procedural manuals), VRSL may stand for VFR Required Separation Lateral – a rule used to maintain lateral separation between Visual Flight Rules (VFR) aircraft and other traffic when vertical or longitudinal separation isn’t possible. This is not an ICAO-standard term (ICAO uses
