How Do Pilots Know When to Abort Landing?

When it comes to landing an aircraft, pilots have an intricate checklist of factors they consider before making a decision. With the safety of passengers and crew at stake, pilots undergo rigorous training to handle various scenarios and make split-second decisions. One of the critical choices they have to make is whether to abort a landing. Let’s delve into the key elements that pilots evaluate to determine when it’s necessary to abort a landing.

First and foremost, pilots rely on their instrument readings and visual cues from the runway. They closely monitor the aircraft’s speed, altitude, and angle of descent. By constantly cross-checking these parameters, pilots can identify any deviations and potential hazards. If they notice an abnormality, such as the aircraft descending too steeply or approaching the runway at a higher speed than recommended, it might trigger an abort decision.

Pilots also factor in the prevailing weather conditions. Poor visibility due to fog, heavy rain, or low clouds can significantly hinder a safe landing. Reduced visibility makes it difficult for pilots to have a clear view of the runway, making it hard to judge the approach accurately. If the visibility drops below a certain threshold specified by the airline or airport regulations, pilots may choose to abort the landing and divert to an alternate airport.

Frequently Asked Questions (FAQs) about Aborting Landing:

1. What is a go-around procedure?

Answer: A go-around procedure, also known as a missed approach, refers to the pilot’s decision to abort a landing and climb back into the air. It is often employed when the aircraft is not in a safe position to continue the landing, or when the pilot is not satisfied with the approach or landing conditions.

2. Are there specific criteria for aborting a landing?

Answer: Yes, each airline and airport has its own set of criteria for aborting landing. These criteria usually include factors such as wind shear, insufficient runway length, poor visibility, unstable approach, or equipment malfunction.

3. How do pilots handle a go-around procedure?

Answer: When a pilot decides to go-around, they increase the engine power, pitch the nose of the aircraft up, and retract the landing gear and flaps. The aircraft then climbs to a safe altitude to re-enter the traffic pattern and prepare for another approach and landing.

4. What is wind shear, and how does it affect landings?

Answer: Wind shear refers to rapid and significant changes in wind speed or direction. It is a significant concern during landing as it can lead to unstable approaches and make it challenging to maintain control of the aircraft. Pilots will often abort a landing if wind shear conditions exceed safety limits.

5. Can a landing be aborted at any time during the approach?

Answer: While pilots have the authority to abort a landing at any point during the approach, there are certain critical phases where it becomes more challenging to safely execute a go-around. These phases include the final stages of the approach, known as the flare and touchdown.

6. Is the decision to abort a landing solely up to the pilot?

Answer: No, the decision to abort a landing is a collaborative effort between the pilot and air traffic control (ATC). ATC may provide critical information or advise the pilot to initiate a go-around based on factors such as runway conditions, traffic, or emergencies.

7. How often do pilots have to abort landings?

Answer: The frequency of aborted landings varies based on several factors, including weather conditions, airport infrastructure, and the pilot’s proficiency. It is difficult to provide an exact number, but pilots are prepared to initiate a go-around if the situation warrants it.

8. Can passengers feel when a pilot aborts a landing?

Answer: In most cases, passengers might not realize that a pilot has initiated a go-around. However, they may notice changes in engine noise, aircraft pitch, or altitude as the aircraft climbs back into the air.

9. What is a missed approach point?

Answer: A missed approach point is a designated point along the approach path where the pilot decides to initiate a go-around if specific criteria are not met. It acts as a reference for the pilot to ensure safe and timely execution of a missed approach.

10. Are there any risks associated with aborting a landing?

Answer: While pilots are trained to handle go-around procedures safely, there are inherent risks involved. These risks include potential problems with aircraft systems, increased fuel consumption, additional stress on the pilots, and the need to coordinate with air traffic control and ground operations for a safe transition.

11. Can an aborted landing result in missed connections or delays?

Answer: In some instances, a go-around can lead to missed connections or delays, depending on the circumstances. However, the primary concern of the pilot and airline is the safety of the passengers and crew, and decisions are made accordingly.

12. How do pilots emotionally handle a decision to abort a landing?

Answer: Pilots are trained to remain calm and maintain a professional demeanor during such situations. They understand that the safety of the aircraft and its occupants is of paramount importance, and their training prepares them to handle the associated emotions and stress effectively.

By considering various factors such as instrument readings, weather conditions, and collaboration with air traffic control, pilots make well-informed decisions about when it is necessary to abort a landing. Their extensive training and expertise ensure the safety of everyone on board, reaffirming the trust we place in these skilled aviation professionals.
