What is G/A on Boeing 777? (Go Around)

Go Around, abbreviated as G/A, is an essential maneuver in aviation, and it plays a crucial role in ensuring the safety and efficiency of aircraft operations. In the context of Boeing 777 aircraft, Go Around refers to the procedure initiated by pilots to abort their approach and climb away from the runway when they determine that it is not safe or feasible to continue with the landing. This blog post will explore the concept of Go Around on the Boeing 777 in detail, discussing its purpose, the factors that may necessitate its execution, and the specific steps involved in carrying out this maneuver.

Understanding Go Around on the Boeing 777

Go Around is a contingency procedure that allows pilots to abort a landing and execute a climb-out from a position close to the runway. It can be initiated at various stages during the approach and landing phase, based on the pilot’s assessment of the situation. The primary purpose of Go Around is to ensure the safety of the aircraft, passengers, and crew by avoiding or mitigating potential hazards. Additionally, Go Around can also be used to enhance operational efficiency, as it allows pilots to make another approach and landing attempt under more favorable conditions.

On the Boeing 777, Go Around is initiated by the captain, who serves as the pilot in command (PIC) of the aircraft. However, the first officer (FO) also plays an important role in assisting with the execution of the maneuver. The decision to initiate a Go Around can be prompted by a variety of factors, including adverse weather conditions, traffic conflicts, runway obstructions, an unstable approach, or an aircraft system malfunction. When any of these situations arise, the pilots must act swiftly and decisively to perform a safe Go Around and ensure the well-being of everyone on board.

During a Go Around on the Boeing 777, the pilot flying (PF) will typically announce their intent to abort the landing by stating “Go Around” over the intercom. Simultaneously, the pilot not flying (PNF) will take action to set the appropriate flight parameters and call out critical speeds and altitudes to assist the PF in executing the procedure accurately. The exact steps and sequences for performing a Go Around on the Boeing 777 may vary slightly depending on the airline’s standard operating procedures and the specific conditions of the situation.

The Process of Executing a Go Around

Executing a Go Around on the Boeing 777 involves a series of precise actions and maneuvers by the flight crew. Here is a step-by-step breakdown of the typical process:

1. Thrust Increase

Upon the captain’s command to execute a Go Around, the first officer quickly advances the thrust levers to increase engine power to a level appropriate for climb-out. The precise thrust setting will depend on various factors, such as aircraft weight, altitude, and environmental conditions. The goal is to achieve a rapid climb while maintaining an appropriate airspeed.

2. Flap Retraction

Once the thrust has been increased, the pilot flying then calls for the retraction of the flaps. The flaps are aerodynamic surfaces on the wings that increase lift during takeoff and landing. In a Go Around scenario, retracting the flaps reduces drag and allows the aircraft to accelerate and climb more efficiently. The pilot not flying will confirm and initiate the flap retraction sequence.

3. Gear Retraction

After the flaps have been retracted, the next step is to retract the landing gear. The landing gear consists of the wheels and structurally supporting components that enable an aircraft to land and take off. During a Go Around, retracting the landing gear further reduces drag and improves climb performance. The pilot not flying will confirm and initiate the gear retraction sequence, while the pilot flying ensures the gear is safely stowed.

These are the fundamental steps involved in executing a Go Around on the Boeing 777. However, it’s important to note that each airline may have slight variations in their procedures, and the flight crew will make adjustments based on the specific conditions and requirements of the situation.

Conclusion

Go Around is a critical maneuver for Boeing 777 pilots, enabling them to abort an approach and perform a climb-out from a position close to the runway. This procedure ensures the safety of the aircraft, passengers, and crew in situations where continuing with the landing would be unsafe or impractical. By understanding the process of executing a Go Around on the Boeing 777, pilots are better equipped to handle unforeseen challenges and maintain the highest standards of safety and efficiency in aviation.
