Emergency landings for flights are not unusual situations in the aviation sector. However, they are occurrences that are best if they do not become recurrent. In recent times, there have been reports of planes making emergency landings across the globe, a more recent one being that of the United Airlines flight UA613 that was headed to Washington, D.C., from Lagos, Nigeria, on the 23rd of January, 2025 but that was forced to make an emergency landing on the 24th of January, 2025 as a result of technical issue and an unexpected aircraft movement.
Some factors are responsible for emergency landings such as engine failure, medical emergencies, severe weather, or security threats.
This article discusses the meaning of emergency landing, types of emergency landing, and factors that can cause emergency landing.
What is an Emergency Landing?
Emergency landing is a broad term for abnormal touchdown situations in aircraft.
It refers to the immediate aircraft landing (or ditching), on or off an airport, due to unforeseen events or actions.
According to Aviation Services, an emergency landing occurs when an aircraft must deviate from its planned route to land immediately due to an unforeseen event.
This situation can arise from various causes such as mechanical failures, engine issues, medical emergencies, severe weather, or threats to security.
Emergency landing can be classified into three broad categories and they are:
1. Forced Landing
A forced landing occurs when an aircraft needs to land immediately, either on an airport or off it, due to the inability to continue the flight. This situation often arises from factors like engine failure, where the pilot has no choice but to land the plane promptly.

2. Precautionary Landing
A precautionary landing is a planned landing, either on or off an airport, when it is deemed unwise to continue the flight as a means of ensuring everyone’s safety.
Various conditions can warrant a precautionary landing, such as worsening weather conditions, becoming lost, running low on fuel, or experiencing gradual engine issues.
3. Ditching
Ditching is a forced landing on water.
When circumstances make it necessary, such as an in-flight emergency over a body of water, the pilot will intentionally land the aircraft on the water’s surface.
This maneuver requires specific procedures and preparations to maximize the chances of survival.
6 Situations That Force Planes to Land Unexpectedly
According to an article by Aviationfile, emergency landings can result from various situations including:
1. Engine Failure or Malfunction
Engine failure is one of the most severe reasons for an emergency landing.
An aircraft experiencing full engine failure or malfunction that affects multiple systems usually necessitates an immediate landing.
2. Fire or Smoke in the Cabin
Any sign of fire or smoke in the cabin is an urgent cause for concern and can result in an emergency landing.
Fire in the aircraft can be a result of electrical failures, cargo issues, or fuel system leaks.
It is important to know that due to the confined space of an aircraft cabin, fire can spread quickly and pose a threat to passengers and crew.
3. Medical Emergencies
Medical emergencies, such as heart attacks or other life-threatening conditions involving passengers or crew members may prompt an emergency landing.
This is however dependent on the severity of the condition and the distance to the nearest suitable airport.
4. Loss of Cabin Pressure
A loss in cabin pressure can mean that there is not enough air for people inside the aircraft to breathe and this can be catastrophic if not addressed promptly.
A sudden loss of cabin pressure will require the pilots to descend to a lower altitude and perform an emergency landing to ensure the safety of those onboard.

5. Weather Conditions
Weather can be as unpredictable as it is powerful, posing significant challenges to aviation.
Severe weather, such as extreme turbulence, hurricanes, high wind,s or thunderstorms, can force a plane to make an emergency landing.
If the weather becomes too dangerous to fly through, pilots may be forced to carry out an emergency landing to avoid putting the passengers and crew at risk.
6. Security Threats
Security threats, such as hijacking attempts, bomb threats, or other illegal activities, are handled with extreme caution by both the flight crew and ATC (Air Traffic Control).
Pilots may initiate an emergency landing to mitigate the danger and allow authorities to intervene.
Other factors that can force a plane to make an emergency landing include shortage of fuel, aircraft component failure, pilot incapacitation, or aircraft damage.
