Landing an airplane in an emergency is arguably one of the most challenging and high-pressure situations a pilot can face. While thorough training is essential, the reality is that circumstances can arise where even experienced pilots may find themselves relying on instinct and a deep understanding of fundamental procedures. This comprehensive guide aims to provide a detailed, step-by-step approach to emergency landings, covering crucial aspects from initial assessment to post-landing actions. Remember, this information is for educational purposes and should not replace formal flight training. Practicing emergency procedures with a certified flight instructor is crucial for developing the skills and confidence necessary to handle real-world emergencies.
Phase 1: Immediate Actions and Assessment
The first few seconds after an emergency occurs are critical. Maintaining control of the aircraft is paramount. Focus on flying the airplane first, then troubleshoot.
- Maintain Aircraft Control: This is the absolute priority. Regardless of the emergency, keep the wings level and maintain a stable airspeed. Avoid abrupt maneuvers that could exacerbate the situation. Use gentle control inputs.
- Identify the Problem: Quickly assess the situation. What is the nature of the emergency? Engine failure? Electrical fire? Control malfunction? Accurate identification is crucial for determining the appropriate course of action.
- Memorize and Execute Immediate Action Items: Most aircraft have emergency checklists that outline immediate action items for various scenarios. These are usually memory items, meaning they should be memorized for quick recall. For example, in the event of an engine failure, immediate actions might include:
- Mixture: Full Rich (unless the failure is due to a fuel-related issue)
- Propeller: Full Forward (if applicable)
- Throttle: Check for smooth operation, then attempt to increase slightly
- Fuel Selector: Switch to the other tank
- Fuel Pump: On
- Magnetos: Check switch position, try switching
- Declare an Emergency: Contact air traffic control (ATC) immediately. Use the phrase “Mayday, Mayday, Mayday” if the situation is life-threatening. Otherwise, use “Pan Pan, Pan Pan, Pan Pan.” Provide the following information:
- Aircraft identification (call sign)
- Nature of the emergency
- Your position (latitude/longitude or radial/distance from a VOR)
- Your altitude
- Your intentions (where you plan to land)
- Number of people on board
Even if you are unsure of your exact location, provide as much information as possible. ATC can use radar to help pinpoint your position and provide assistance.
- Squawk 7700: Set your transponder code to 7700, the universal emergency code. This immediately alerts ATC that you are in distress.
Phase 2: Finding a Suitable Landing Area
Once the immediate actions are complete, focus on finding a suitable landing area. Time is of the essence, so make quick, decisive choices.
- Prioritize Landing Areas: Consider the following factors when evaluating potential landing sites, in order of importance:
- Runways: An airport is always the best option. Even a small, unpaved airstrip is preferable to a field.
- Open Fields: Look for large, flat fields with few obstructions. Avoid fields with trees, power lines, or fences.
- Roads: A straight, lightly traveled road can be used as a last resort. Be aware of the risks involved, such as traffic and obstacles.
- Bodies of Water: Only consider water landings as a last resort, and only if properly trained. Aircraft are not designed to float for long.
- Assess Wind Conditions: Determine the wind direction and strength. Try to land into the wind to reduce ground speed and shorten the landing distance. Use the aircraft’s weather instruments, or look for visual cues such as smoke plumes, wind socks, or the direction of ripples on water.
- Consider Surface Conditions: Assess the surface of the landing area. Is it smooth and firm, or rough and soft? A soft surface will increase the landing distance. Look for potential hazards such as holes, rocks, or crops.
- Evaluate Obstacles: Identify any obstacles in the approach path or on the landing surface. Trees, power lines, and buildings can pose a significant threat. Plan your approach to avoid these obstacles.
- Communicate Your Intentions: Inform ATC of your chosen landing site. They may be able to provide additional information about the area, such as wind conditions or potential hazards.
- Circle Above Landing Site: If time permits, circle above your chosen landing area to thoroughly assess the conditions and plan your approach. This allows you to refine your landing strategy and identify any potential problems.
Phase 3: Preparing for Landing
With a suitable landing area selected, the next step is to prepare the aircraft and the passengers for landing.
- Establish Best Glide Speed: Maintain the aircraft’s best glide speed (Vg). This is the speed at which the aircraft will travel the furthest distance for a given altitude. Refer to your aircraft’s Pilot Operating Handbook (POH) for the best glide speed.
- Configure the Aircraft: Prepare the aircraft for landing as much as possible. This may include:
- Extending flaps (if possible and appropriate)
- Lowering the landing gear (if applicable and time permits)
- Adjusting the trim for the landing configuration
However, prioritize maintaining control of the aircraft. Don’t get so focused on configuring the aircraft that you lose situational awareness.
- Brief Passengers: Inform your passengers of the situation and what to expect during the landing. Instruct them to brace for impact. Ensure they have their seatbelts securely fastened. Secure any loose objects in the cabin that could become projectiles during the landing.
- Prepare for Impact: Adopt the brace position. This typically involves leaning forward, placing your hands on your head, and tucking your chin to your chest. This will help protect your head and neck in the event of a hard landing.
- Consider Shutting Down Systems: If time permits and the situation warrants it, consider shutting down unnecessary systems, such as the electrical system and the fuel supply. This can help reduce the risk of fire after the landing. Follow your emergency checklist procedures.
Phase 4: The Approach and Landing
The approach and landing are the most critical phases of an emergency landing. Precision and control are essential.
- Fly a Stabilized Approach: Maintain a consistent airspeed, descent rate, and angle of approach. Avoid steep turns or abrupt changes in airspeed.
- Use Flaps Judiciously: Use flaps as appropriate for the landing conditions. Flaps increase lift and drag, allowing for a slower landing speed and a steeper approach angle. However, be aware that extending flaps can also increase the stall speed. If you are unsure, it may be best to use partial flaps or no flaps at all.
- Slipping the Aircraft: If you are too high on approach, use a forward slip to increase the descent rate without increasing airspeed. To perform a forward slip, apply rudder in one direction and aileron in the opposite direction. For example, apply right rudder and left aileron. The amount of rudder and aileron will determine the descent rate. Remember to coordinate the controls before touchdown to prevent a wing from dropping.
- Maintain Airspeed Control: Accurate airspeed control is crucial. Fly slightly above the stall speed to provide a margin of safety. Avoid excessive airspeed, which can lead to a long landing.
- Touchdown: Aim for the beginning of the landing area. Touch down as smoothly as possible. If the landing is rough, maintain directional control and prepare for a go-around if necessary. However, in an emergency landing, a go-around may not be possible, so be prepared to accept the landing.
- Braking: Apply the brakes firmly but smoothly. Avoid locking the brakes, which can cause the aircraft to skid. Use differential braking (applying more brake pressure to one wheel than the other) to maintain directional control.
- Maintain Directional Control: Use the rudder and brakes to maintain directional control after touchdown. Be prepared to steer the aircraft to avoid obstacles.
Phase 5: Post-Landing Procedures
Once the aircraft has come to a stop, there are several important post-landing procedures to follow.
- Secure the Aircraft: Shut down the engine (if it’s still running) and set the parking brake. Turn off the electrical system and the fuel supply.
- Evacuate the Aircraft: Evacuate the aircraft as quickly and safely as possible. Assist any injured passengers. Move away from the aircraft to a safe distance.
- Assess Injuries: Assess the injuries of yourself and your passengers. Provide first aid as necessary.
- Contact Emergency Services: Contact emergency services (if they have not already been contacted). Provide them with the location of the aircraft, the number of people on board, and the nature of any injuries.
- Preserve the Scene: Do not disturb the accident site unless it is necessary to prevent further injury or damage. The accident site will be investigated by aviation authorities.
- Cooperate with Investigators: Cooperate fully with the aviation authorities investigating the accident. Provide them with all relevant information, including your flight plan, weather conditions, and any other factors that may have contributed to the accident.
Specific Emergency Scenarios
While the general principles outlined above apply to most emergency landings, some specific scenarios require additional considerations.
Engine Failure
- Immediate Actions: As previously mentioned, the immediate actions for an engine failure are crucial. Refer to your aircraft’s emergency checklist.
- Best Glide Speed: Maintain the aircraft’s best glide speed.
- Landing Area Selection: Prioritize landing areas that are within gliding distance.
