Visibility Runway
A precise tool.
What is the Visibility Runway & How does it work?
Runway Visual Range (RVR) is a critical measurement in aviation that indicates the distance a pilot can see down the runway under existing conditions. It affects approach minima, which are the minimum standards that must be met for an aircraft to safely land.
Approach minima are determined by factors such as the type of approach (e.g., ILS, VOR), the category of the aircraft, and the RVR. For example, a Category IIIb approach requires lower RVR values than a Category I approach.

Frequently Asked Questions
What is Runway Visual Range (RVR)?
Runway Visual Range (RVR) is the distance a pilot can see down the runway under existing conditions, crucial for determining approach minima.
How does RVR affect aircraft landing?
Lower RVR values require pilots to maintain higher approach speeds and greater distances from the runway, impacting landing safety.
What are the different categories of approaches in aviation?
Approach categories include ILS (Instrument Landing System), VOR (VHF Omnidirectional Range), and others, each with specific RVR requirements.
How is RVR measured?
RVR is typically measured using transmissometers or other optical instruments that detect the runway surface visibility.
What is the difference between Category I and Category IIIb approaches?
Category I approaches have higher RVR requirements than Category IIIb, which allow for lower minimums under poor visibility conditions.
How do pilots use RVR information during landing?
Pilots use RVR to adjust their approach speed and path, ensuring they maintain sufficient visibility to safely land the aircraft.
What factors can affect RVR measurements?
Factors such as weather conditions, runway surface, and lighting can impact RVR measurements, affecting landing safety.
