Go–Around (GA) is a term frequently used in the aviation industry to refer to a standard procedure performed by pilots when landing an aircraft is not possible or safe. It involves aborting the landing approach and initiating a climb to gain altitude for another attempt at landing. This maneuver is crucial in ensuring the safety of the passengers, crew, and the aircraft itself. In this article, we will explore the details of the Go–Around procedure specifically for the popular Boeing 737 aircraft.
Understanding the Go–Around Procedure
The Go–Around procedure is initiated by the pilot-in-command (PIC) when certain conditions are met during the landing approach. These conditions may include but are not limited to:
- Poor visibility
- Unstable approach
- Runway incursion
- Weather conditions outside acceptable limits
- Aircraft ahead not clear of the runway
Once the decision for a Go–Around is made, the pilot will announce it to the air traffic control (ATC) and take necessary actions to execute the maneuver. The specific steps to perform a Go–Around on the Boeing 737 may vary slightly based on airline procedures, but they generally follow a similar sequence:
- Power up: The pilot will advance the thrust levers to increase engine power and initiate the climb.
- Positive rate of climb: Once airborne, the pilot will establish a positive rate of climb by retracting the landing gear and flaps to clean up the aircraft for the climb.
- Follow ATC instructions: The pilot will closely monitor air traffic control instructions during the climb, ensuring safe separation from other aircraft.
- Reconfigure the aircraft: At an appropriate altitude, the pilot will configure the aircraft for the next approach by extending the flaps and landing gear.
- Prepare for another landing attempt: The pilot will follow the standard procedures for setting up a new landing approach, including establishing the correct approach speed and configuring the aircraft accordingly.
Importance of Go–Around in Safety
The Go–Around procedure plays a critical role in ensuring the safety of passengers, crew, and the aircraft. It is a proactive measure to avoid potential accidents or incidents during the landing phase. By initiating a Go–Around, pilots can address various factors that may compromise the safety of the landing, such as:
- Unstable approach: If an approach becomes unstable, it significantly increases the risk of a hard landing or runway excursion. Going around allows the pilot to stabilize the approach before attempting another landing.
- Poor visibility: Reduced visibility due to fog, rain, or other weather conditions can make it difficult for pilots to maintain visual references required for a safe landing. A Go–Around provides an opportunity to wait for improved visibility or consider an alternative landing option.
- Runway incursion: In the event of an incursion by another aircraft, vehicle, or object on the runway, a Go–Around ensures that the landing is aborted to avoid a potential collision.
- Weather conditions: If weather conditions exceed the aircraft’s capabilities or operational limits, such as strong crosswinds or severe turbulence, a Go–Around provides an alternative to safely abort the landing and wait for improved conditions.
These are just a few examples of situations where a Go–Around can prevent accidents and maintain a high level of safety. Pilots undergo extensive training to recognize and respond to such conditions effectively, ensuring the best possible outcomes for all onboard.
Conclusion
The Go–Around procedure is an integral part of aviation safety and is crucial for the Boeing 737 aircraft, as well as all other aircraft. It allows pilots to take proactive measures to ensure safe landings by aborting the approach when necessary. By following a standardized sequence of steps, pilots can climb to a safe altitude and set up for another landing attempt. Ultimately, the Go–Around procedure serves as a proactive mitigation strategy, addressing various factors that could compromise the safety of the landing. Passengers can be reassured that their safety is of paramount importance to the pilots and the aviation industry as a whole.
