• A KLM-operated Boeing 777-200ER experienced an in-flight emergency
• This incident happened shortly after leaving Amsterdam Schiphol Airport.
• The plane departed at approximately 13:00 CEST and initially climbed to a cruising altitude of 34,000 feet.
• While flying over the northern region of Scotland, the pilots issued a general emergency alert by broadcasting squawk code 7700.
• After the emergency call, the aircraft changed course and headed south for an unscheduled diversion.
• The situation resulted in the flight abandoning its planned route due to an emergency onboard.

You’re definitely thinking where you’ll end up, how you’ll get there, and when! Flight diversions, whether you’ve had them before or not, are an unpleasant surprise that can create a great deal of tension. Our Guider will explain what flight diversions are, why they occur, how much compensation you may expect from the airline, and what you should do if this happens to you.

Reasons Why Flights Are Diverted

Flight diversions are an essential part of aviation safety. While they may inconvenience passengers, diversions are carefully planned decisions made to protect everyone on board. Below are the most common reasons why an aircraft may be forced to change its destination.

1. Medical Emergencies Onboard

One of the most frequent causes of flight diversion is a medical situation involving a passenger or crew member. When a health issue becomes serious and cannot be managed safely in the air, pilots may choose to land at the nearest suitable airport.

Common examples include:

• Severe breathing difficulties
• Heart-related symptoms
• Loss of consciousness
• Allergic reactions requiring urgent care

Aircraft crews receive medical guidance from ground-based professionals, but time-sensitive cases often require immediate landing.

2. Technical or Mechanical Issues

Even with strict maintenance standards, aircraft systems can develop unexpected faults during flight. While many issues are minor, some require precautionary landings to ensure safety.

Typical technical concerns include:

• Engine abnormalities
• Pressurization problems
• Hydraulic or electrical failures
• Warning system alerts

Modern aircraft are designed with backups, but pilots always prioritize caution over risk.

3. Adverse Weather Conditions

Weather plays a major role in aviation decision-making. Sudden changes such as strong storms, heavy snowfall, or poor visibility can make landing at the planned destination unsafe.

Weather-related diversions may occur due to:

• Thunderstorms near the airport
• Strong crosswinds
• Fog reduces runway visibility
• Volcanic ash or extreme turbulence

In such cases, aircraft divert to airports with safer conditions.

4. Security Threats or Safety Concerns

Any potential threat to onboard safety is treated seriously. This may involve unruly passengers, suspicious behavior, or external threats that require immediate action.

Examples include:

• Aggressive or disruptive passengers
• Suspected security risks
• Smoke or unusual odors in the cabin

Diverting allows authorities to address the situation safely on the ground.

5. Airport or Airspace Restrictions

Sometimes the issue is not with the aircraft but with the destination itself. Runway closures, congestion, or unexpected airspace restrictions can force pilots to select an alternate airport.

Possible causes include:

• Closed runways due to accidents
• Air traffic congestion
• Military or emergency airspace activity

Conclusion

Although KLM flight KL635 diverts to Glasgow after declaring emergency can be frustrating, they are a sign that safety systems are working exactly as intended. Every diversion reflects a careful decision made to protect passengers, crew, and aircraft above all else.
