Pattern and Landing Emergencies

Avoiding Engine Problems

Prevention is always better than cure. Many engine failures are the result of poor engine management by the pilot. Follow these practices to minimize the risk of engine problems:

• Proper warm-up: Allow the engine to reach normal operating temperatures before applying high power. Follow the POH recommended warm-up procedure.
• Carburetor heat: Apply carburetor heat regularly during flight and always before reducing power. Carburetor ice is one of the most common causes of partial or full power loss in training aircraft.
• Fuel management: Verify fuel quantity before flight. Select the correct fuel tank. Monitor fuel consumption against planned values. Switch tanks at regular intervals if applicable.
• Mixture: Set mixture appropriately for altitude. Over-leaning can cause engine damage or failure. Enrichen the mixture before applying full power.

Abandoned Takeoff

The decision to abort a takeoff must be made before the takeoff begins. During your pre-takeoff briefing, identify a go/no-go point on the runway — if the aircraft has not achieved the expected performance by that point, you will abort.

Reasons to Abort

• Engine not developing full power (RPM or manifold pressure below normal)
• Airspeed not alive or not increasing as expected
• Engine roughness or abnormal indications
• Directional control problems
• Door or window opening
• Obstruction on the runway (aircraft, vehicle, wildlife)
• Any situation that makes you uncomfortable with continuing

Abandoned Takeoff Procedure

1. Throttle — idle. Reduce power immediately.
2. Brakes — apply. Use maximum braking as required to stop on the remaining runway.
3. Maintain directional control. Keep the aircraft on the centerline with rudder and differential braking.
4. Flaps — retract (if extended) to place more weight on the wheels for better braking.
5. Once stopped, clear the runway and assess the situation.

Engine Failure After Takeoff

Engine failure immediately after takeoff is the most critical emergency a pilot can face. You are at low altitude, low airspeed, and in a nose-high attitude. The immediate priority is to prevent a stall.

Immediate Actions

1. Lower the nose immediately — pitch to the best glide attitude. This is the single most important action. Without airspeed, you have no options.
2. Land straight ahead — or with only minor turns (up to 30 degrees) to avoid obstacles.
3. Do NOT attempt to return to the runway.

The instinct to turn back to the runway is strong — behind you is a long, clear, paved surface. But attempting to return is almost always fatal at low altitude. This is known as the "impossible turn".

Why Not Turn Back? (The Impossible Turn)

The mathematics and physics of the turn-back maneuver demonstrate why it fails at low altitude:

• To return to the runway, you must complete approximately a 180-degree turn (actually more, accounting for wind and alignment).
• In the turn, the aircraft loses altitude due to the increased load factor and reduced lift component.
• The turn must be made at a relatively steep bank angle to minimize altitude loss — but steep bank at low speed is dangerously close to the accelerated stall speed.
• Wind pushes you further from the runway during the turn (you took off into wind, so turning back puts the wind behind you).
• The total altitude required to complete the turn-back safely is typically 800-1,000 feet AGL minimum — and most engine failures after takeoff occur well below this altitude.

Accident statistics consistently show that pilots who attempt the turn-back at low altitude have a very high fatality rate. Pilots who land straight ahead — even in unsuitable terrain — have a much higher survival rate.

Engine Failure in the Pattern

If the engine fails at pattern altitude (typically 1,000 feet AGL), you have more options than immediately after takeoff — but time is still very limited.

On Downwind

• You are at pattern altitude with the runway alongside you.
• Immediately turn toward the runway — you may be able to glide to a modified base and final.
• Pitch for best glide speed. Do not waste altitude trying to reach a distant point on the runway.
• Accept a landing on any available portion of the runway, or a suitable area short of the runway if you cannot reach it.

On Base Leg

• You are already turning toward the runway and relatively close.
• Pitch for best glide speed and continue the turn to final.
• Adjust your aim point — you may need to land on the first third of the runway rather than your normal touchdown point.

On Final

• You are already aligned with the runway.
• Pitch for best glide speed.
• If you are too high, use flaps or a forward slip to increase the descent rate.
• If you cannot reach the runway, select the best available landing area ahead of you.

Radio Failure in the Pattern

If your radio fails while in the traffic pattern at a controlled airport:

1. Squawk 7600 on the transponder (the radio failure code).
2. Continue flying the standard traffic pattern. Maintain normal pattern procedures — the tower will be expecting you to do this.
3. Watch for light signals from the control tower:

Light Signal	Meaning (In Flight)
Steady green	Cleared to land
Flashing green	Return for landing (cleared to approach)
Steady red	Give way to other aircraft and continue circling
Flashing red	Airport unsafe — do not land
Flashing white	Not applicable in flight (ground signal only)
Alternating red and green	Exercise extreme caution

4. Acknowledge that you have seen the light signal by rocking your wings (in flight) or by moving your ailerons or rudder (on the ground).

Purpose

To practice the correct responses to engine failures and other emergencies during the takeoff roll, immediately after takeoff, and at various positions in the traffic pattern. The emphasis is on pre-planned decision-making and immediate, correct responses.

Abandoned Takeoff Practice

Your instructor will simulate situations requiring an aborted takeoff during the takeoff roll. Practice the following sequence until it becomes automatic:

1. Recognition: Identify the abnormality (engine roughness, abnormal indications, obstruction).
2. Decision: "Aborting takeoff."
3. Throttle — idle. Close the throttle completely and immediately.
4. Brakes — maximum. Apply firm, progressive braking.
5. Directional control. Maintain centerline with rudder and differential braking.
6. Flaps — retract (if extended).
7. Clear the runway when safe to do so.

Engine Failure After Takeoff

Your instructor will simulate an engine failure at various altitudes after takeoff (by reducing power to idle). Your response must be immediate and correct:

Immediate Actions

1. Pitch for best glide speed. Lower the nose immediately to maintain V_G (best glide speed — typically 65 knots in a Cessna 172). This is the single most critical action.
2. Select a landing area. Look straight ahead or with only minor deviations (30 degrees maximum). Choose the best available option — a field, road, or open area.
3. Wings level. Do not turn. Minor heading changes only if required to avoid an obstacle directly ahead.
4. If time permits: Attempt an engine restart (fuel selector, mixture, magnetos, carburetor heat). But do NOT sacrifice airspeed or altitude to troubleshoot.
5. Prepare for landing: Flaps as appropriate for the landing area. Secure the aircraft (mixture idle cutoff, fuel off, master off) if time permits.

Engine Failure in Various Pattern Positions

Your instructor will simulate engine failures at different points in the traffic pattern. For each scenario, practice the following:

On Crosswind Leg

1. Pitch for best glide speed immediately.
2. Assess whether you can reach the runway with a turn back. At low altitude on crosswind, this is unlikely — treat it as an engine failure after takeoff and land ahead.
3. At higher altitudes on crosswind, a modified return to the runway may be possible.

On Downwind Leg

1. Pitch for best glide speed immediately.
2. Turn toward the runway — you are at pattern altitude and the runway is beside you.
3. Plan a shortened approach — base and final may be compressed.
4. Accept any available portion of the runway. Do not try to reach your normal touchdown point if it means stretching the glide.

On Base Leg

1. Pitch for best glide speed.
2. Continue the turn to final — you are already close to the runway.
3. Adjust aim point as needed. Use flaps judiciously (they increase descent rate but also reduce glide range).

On Final Approach

1. Pitch for best glide speed.
2. You are already aligned with the runway — continue the approach.
3. If too high: add flaps or slip to increase descent rate.
4. If too low or cannot reach the runway: select the best available landing area ahead and below you.

Key Takeaways

Engine Failure After Takeoff Is the Most Dangerous Emergency

At low altitude, with low airspeed and a nose-high attitude, there is almost no margin for error. The correct response must be pre-planned and executed immediately without hesitation. There is no time to think — only to act on a decision already made.

Decision-Making Must Be Pre-Planned

Before every takeoff, brief your emergency plan:

• On the ground: If anything is abnormal during the takeoff roll, I will abort (throttle idle, brakes, maintain directional control).
• Below 500 feet AGL: If the engine fails, I will lower the nose and land straight ahead.
• Above 500 feet AGL: I will consider a modified pattern, but only if I have sufficient altitude and a clear area to land.
• At pattern altitude: I will turn toward the runway and plan a glide approach.

The Impossible Turn

Altitude (AGL)	Recommended Action
0-500 ft	Land straight ahead. No turns except minor deviations to avoid obstacles.
500-800 ft	Land ahead with minor turns (up to 30 degrees). Turning back is extremely high risk.
800-1,000+ ft	Turn-back may be possible IF practiced and pre-briefed. Still high risk. Landing ahead remains the safest option in most cases.

Critical Points to Remember

• Lower the nose first — airspeed is life. Without airspeed, you have zero options.
• Never attempt the impossible turn at low altitude — the physics do not allow it below 800-1,000 feet AGL.
• A controlled off-airport landing is survivable — a stall/spin from a turn-back attempt is almost always fatal.
• Brief your plan before every takeoff — the decision must be made on the ground, not in the emergency.
• Prevention is key — proper warm-up, carburetor heat, fuel management, and mixture settings prevent most engine failures.
• Know the light signals — in case of radio failure at a controlled airport.

Lesson Plan

Where this fits: Exercise 12a in Stage 3 (Traffic Pattern), the second of the four lessons that close the PPL simulator track. Now that the student can fly the pattern from Lesson 11, this session adds the emergency responses that belong in those same takeoff, pattern, and landing phases — the simulator is the safe place to rehearse failures that cannot be practiced on a live runway.

Prerequisite

Lesson 11 — Takeoff and Climb to Downwind (can fly a stabilized takeoff, climb, and downwind leg).

Materials

C172 G1000 simulator, emergency and engine-failure checklists, airport diagram, and the best-glide VG reference.

Objectives for this session

Run the abandoned-takeoff sequence — recognize, decide, throttle idle, brakes, directional control — until it is automatic.

Respond to a simulated engine failure after takeoff by pitching immediately for VG, selecting a landing area ahead, and landing straight rather than turning back below 800–1,000 feet AGL.

Handle simulated engine failures on crosswind, downwind, base, and final, maintaining glide-range awareness throughout the pattern.

Looking Ahead

Next session is Lesson 13 — Glide Approach and Landing, which turns the engine-failure glide into a repeatable power-off approach and landing technique.
