A go-around is a planned safety maneuver in which a pilot stops the landing attempt, adds power, and climbs away from the runway. It is used when the approach is unstable, the runway is blocked, spacing is unsafe, weather changes suddenly, or the aircraft is not configured correctly. In aviation, a go-around is normal and expected, not a failure.
It protects passengers and crew by choosing altitude and time over forcing a risky landing.
During a go-around, thrust increases first, then the aircraft pitches to a climb attitude and accelerates or holds a safe climb speed. Lift must exceed weight enough to create an upward acceleration or at least support a steady climb, while thrust helps overcome drag and build energy. Pilots follow a published missed approach path or air traffic control instructions so the aircraft remains clear of obstacles and other traffic.
The maneuver is a strong example of physics in action because power, lift, drag, weight, speed, and climb angle all change together.
Understanding Aviation: The Go-Around
The hard part of a go-around is often the decision, not the control movement. Near the ground, people naturally focus on reaching the runway. This can create plan continuation bias.
It means continuing with an original plan even after conditions no longer support it. Professional pilots reduce this risk by setting clear limits before the approach begins. They agree on what must be seen, heard, and felt by a certain height.
If a limit is missed, the next action is already decided. This removes argument and delay during a busy phase of flight. Crews use standard callouts so both pilots recognize the change from landing mode to climbing mode.
Adding thrust is not an instant cure because engines need time to produce more power. Jet engines can take several seconds to spool up, especially at low power settings. During that time, the aircraft may still be descending.
Pilots therefore use a known pitch attitude and closely monitor speed. Too much pitch can slow the aircraft toward a stall. Too little pitch can leave it close to the ground for longer than planned.
The pilot flying controls the aircraft while the other pilot checks power, flap settings, gear position, and navigation guidance. Aircraft procedures specify when landing flaps can be reduced and when the landing gear can be raised. Changing these settings too early or too late can affect drag, climb performance, and control feel.
A missed approach route is designed around obstacle clearance, but it has limits. Charts may require the aircraft to climb at a minimum gradient before making a turn or reaching a stated altitude. A heavily loaded aircraft on a hot day climbs less strongly because warm air is less dense and the engines produce less thrust.
High airports create a similar problem. Wind matters too. A headwind reduces ground distance covered during a climb, which can improve the climb gradient over the ground.
A tailwind does the opposite. Pilots compare aircraft performance with the published requirement before departure and again when conditions change. Air traffic control may give different instructions, but pilots still must ensure the aircraft can safely meet them.
Students can notice the same energy ideas in a car joining a fast road. The driver needs enough space, speed, and a clear path. If those are missing, continuing can be unsafe.
In flight training, go-arounds are practised repeatedly because they build judgment as well as handling skill. A good practice session includes approaches stopped at different points, including before touchdown and after a bounce. Students should pay attention to priorities.
First keep the aircraft under control. Next follow the published or assigned path.
Then communicate and complete checks when workload allows. This order matters because a perfect radio call cannot compensate for poor speed control or an unsafe flight path.
Key Facts
- A go-around begins when the pilot adds thrust and transitions from descent to climb.
- Lift force depends on airspeed, wing area, air density, and angle of attack: L = 0.5ρv^2CL A.
- Weight acts downward and must be balanced or exceeded by lift during the climb: W = mg.
- Net vertical force controls vertical acceleration: ΣFy = ma.
- Climb gradient is the height gained per horizontal distance: climb gradient = altitude gain / horizontal distance.
- A stabilized approach usually requires correct speed, descent rate, runway alignment, aircraft configuration, and checklist completion before landing.
Vocabulary
- Go-around
- A go-around is a maneuver in which an aircraft discontinues a landing approach, adds power, and climbs away for another attempt or a new clearance.
- Final approach
- Final approach is the last straight or nearly straight segment of flight toward the runway before landing.
- Thrust
- Thrust is the forward force produced by engines or propellers that helps the aircraft accelerate and climb.
- Climb gradient
- Climb gradient is the ratio of altitude gained to horizontal distance traveled during a climb.
- Missed approach
- A missed approach is a published or assigned procedure that guides an aircraft safely away from the runway after a landing is not completed.
Common Mistakes to Avoid
- Thinking a go-around means the pilot made a mistake is wrong because it is a routine safety choice used whenever landing conditions are not acceptable.
- Waiting too long to add power is wrong because the aircraft may lose airspeed and altitude margin near the ground.
- Pulling the nose up sharply without enough airspeed is wrong because too much angle of attack can reduce airflow over the wing and lead to a stall.
- Ignoring the missed approach path is wrong because that path is designed to keep the aircraft clear of terrain, obstacles, and other traffic.
Practice Questions
- 1 An aircraft climbs 600 ft while traveling 2.0 nautical miles horizontally during a go-around. What is its climb gradient in ft per nautical mile?
- 2 A 70,000 kg aircraft begins a go-around. What is its weight in newtons if g = 9.8 m/s^2?
- 3 A runway vehicle appears ahead just as an aircraft is aligned and close to landing. Explain why adding power and climbing away is safer than trying to continue the landing.
