MVA

Definition of MVA

MVA or Minimum Vectoring Altitude refers to the lowest altitude at which air traffic control can vector an aircraft safely. It is intended to provide sufficient obstacle clearance within a specified distance from the centerline of an air traffic route or instrument approach procedure.

MVA is established after taking into account the highest obstacle or terrain on the route. MVA also ensures that the required communication, navigation, and surveillance performance specifications are met. This altitude is usually used in non-radar areas to prevent an aircraft from colliding with terrain or obstacles while it is being vectored or directed by air traffic control.

MVA is a crucial component of aviation safety, as it minimizes the risk of a collision between an aircraft and obstacles or terrain. Pilots should always be aware of the MVA for their flight when departing from an airport, en route, or approaching an airport. Air traffic controllers also play a vital role in ensuring the safety of flights by directing them to the appropriate MVA.

In conclusion, MVA is the minimum altitude that air traffic control must maintain when vectoring aircraft to ensure safe obstacle clearance during non-radar operations.
