When RVR (Runway Visual Range) is reported as 6-M-6, it indicates a visibility of 6 meters for a component of the approach. In aviation, certain visibility minimums are established for departures, especially in low-visibility conditions. The crucial aspect here is that an RVR of 6 meters is significantly low, and it typically does not meet the minimum requirements for a safe takeoff. In most jurisdictions, regulatory bodies such as the FAA or EASA set specific minimum RVR values that must be met for departures to ensure safe operations. If the reported RVR is below these minimums, it is deemed unsafe to commence the departure due to potential inability to see the runway or any obstacles in the area. Additionally, runway conditions, presence of obstacles, and potential difficulties in gaining altitude safely under such conditions further contribute to the decision to refrain from departing when visibility is critically low. Therefore, the decision of not departing when RVR is reported as 6-M-6 is based on safety considerations and compliance with aviation regulations regarding visibility and operational limitations.
