What altitude should an aircraft NOT exceed during a go-around or low approach until cleared?

During a go-around or low approach, an aircraft should not exceed 700 feet MSL (Mean Sea Level) until it receives clearance. This altitude restriction is primarily in place to maintain safe separation from other aircraft and to comply with controlled airspace requirements. The FAA and other aviation regulatory bodies emphasize the importance of adhering to these altitude limits to prevent conflicts with other traffic and to ensure a standard procedure is followed for aircraft operations in the vicinity of an airport.

Choosing this altitude helps pilots maintain visual contact with the runway environment and provides adequate safety margin during these critical phases of flight. Furthermore, it supports the collective effort to keep airspace organized, particularly in busy terminal areas where many aircraft may be operating at various altitudes.
