Can A Plane Fly If Both Engines Fail? | Glide Distance Facts

Airliners can glide on stored speed and altitude, giving crews minutes to reach a runway or suitable landing spot.

“Both engines failed” sounds like a drop straight down. In real flight, the airplane still has wings, lift, and momentum. With thrust gone, it becomes a glider that trades height for distance.

So, yes: an airliner can stay in controlled flight after losing thrust in both engines. It can cover miles. The hard limit is altitude. When altitude is spent, the flight ends with a landing, a ditching, or an off-airport touchdown.

What “Flying” Means With No Thrust

In aviation, “fly” means the wings keep producing lift and the crew keeps control of direction, speed, and attitude. Engines add range and climb, but they don’t hold the airplane up by themselves.

Once thrust is gone, the cockpit focus turns into energy management. Altitude and airspeed are the only “fuel” left. The crew guards that fuel while they pick a landing site and try to restore thrust.

How Both Engines Can Stop Producing Thrust

Dual engine thrust loss is rare, and it tends to follow a chain of events. Crews train for it because the first minutes move fast.

• Fuel issues: starvation, contamination, or feed faults that cut usable fuel.
• Bird strikes: multiple birds can disable both engines near takeoff or climb.
• Volcanic ash: ash ingestion can trigger flameout and damage compressors.
• Severe hail or ice: enough ingestion can cause stall or flameout.
• Multiple system faults: rare failures tied to fuel valves or control logic.

Airline routing rules, alternates, and dispatch planning reduce risk and keep diversion airports within reach. Those layers are built around one-engine performance, yet they still shape routes in a way that can help in a glide emergency.

Can A Plane Fly If Both Engines Fail? What Glide Flight Looks Like

With both engines not producing thrust, the airplane keeps going ahead and down. If the crew holds the right speed, the wings stay efficient and the glide goes farther. If speed drifts too slow or too fast, drag rises and altitude disappears faster.

Glide Ratio In Plain Terms

Glide ratio is ground distance compared with altitude lost. Wind, weight, and configuration can swing real-world range by miles. That’s why pilots do not rely on a single “it can glide X miles” number.

A clean mental model works well: altitude is range. From cruise altitude, a jet may have enough height to glide dozens of miles. From low altitude after takeoff, the circle of options can shrink to minutes.

Best Glide Speed And Why It Shows Up In Checklists

Each airplane has a speed that trades height for distance in the most efficient way. Pilots call it best glide. For transport jets, the flight management system and checklists point crews toward target speeds that keep the airplane in a stable energy state while they work the failure. The FAA’s short note on best glide speed and distance explains the concept in practical terms.

What The Crew Does First

In the cockpit, the order is disciplined: keep control, run memory items, work the checklist, then set up the landing. That order stays steady because losing control wipes out options fast.

Stabilize Speed And Flight Path

The pilot flying sets pitch to hold a safe glide speed. If the autopilot remains available, it can help keep the airplane stable while the crew starts troubleshooting. If it drops offline, the pilot hand-flies and keeps the scan tight.

Try An Engine Relight Early

Some flameouts relight if fuel flow is restored and ignition is selected at the right conditions. Crews attempt relight steps early because altitude is time, and time buys more attempts.

Restore Backup Power

Most airliners have batteries, and many have an auxiliary power unit (APU) that can supply electrical power in flight. Some types also deploy a ram air turbine to keep core systems alive. Backup power keeps radios and flight instruments working longer, which helps with routing and landing setup.

Declare Emergency And Pick A Landing Site

The crew tells air traffic control what’s happening and asks for the nearest runway options. They turn toward the best landing site based on distance, wind, terrain, and runway length. Early turns matter, since turning late can waste the last miles of range.

What You Might Notice In The Cabin

Cabin clues depend on the airplane and the phase of flight. Some changes are subtle.

• Sound: engine noise drops away; wind noise can rise.
• Attitude: a gentle nose-down glide can feel like a steady descent.
• Systems: cabin services may reduce if generation is limited.
• Briefing: crew instructions may get short and direct.

Glide Setup Choices That Change Range

With thrust gone, drag becomes the enemy. A clean airplane glides farther. Adding gear or flaps increases drag and shortens range, yet those items are needed to land at the right speed.

Clean First, Configure Late

Most crews keep the airplane “clean” at first: gear up and flaps retracted. Later, once the landing site is made, they add drag in steps to control speed and hit the touchdown zone. Dropping gear too early can be the difference between reaching the runway and landing short.

Turns Spend Height

Each turn increases drag. Gentle turns can still be worth it to line up with a runway or avoid terrain. Steep turns can eat altitude fast. Crews keep turns smooth and purposeful.

Wind Can Add Ground Miles Or Steal Them

A tailwind can stretch the ground distance covered during a glide. A headwind can shrink it. Crosswind can force extra maneuvering. Crews factor wind into runway choice and approach direction.

The table below sums up early cockpit priorities and what each one affects.

Moment In The Event	What The Crew Works On	What It Changes
First 10 seconds	Set pitch and speed near glide target	Preserves range and prevents speed decay
First 30 seconds	Confirm thrust loss, start memory items	Reduces wrong switch moves and saves time
First 1–2 minutes	Engine relight attempts, start APU if allowed	May restore thrust or extend electrical power
2–4 minutes	Declare emergency, request vectors, pick landing site	Sets the path and trims workload
4–8 minutes	Brief approach, cabin prep, stay clean	Protects glide distance while setting up
Final minutes	Gear and flap timing, aim point control	Trades remaining height for touchdown control
After landing	Stop, evacuate, account for people	Moves passengers away from hazards

What Real Reports Show About Dual Engine Landings

Dual engine failures have happened, and investigators have studied them in detail. A well-known case is US Airways Flight 1549, where a bird strike after takeoff led to an almost complete loss of thrust in both engines and a controlled ditching in the Hudson River.

The National Transportation Safety Board’s Aviation Accident Report AAR-10/03 documents the sequence and the factors that shaped the outcome, including altitude available and decision timing.

The lesson is simple: a jet without thrust can still be flown, aimed, and landed under control when the crew manages energy and makes disciplined choices.

Choosing Between A Runway And A Non-Runway Landing

The crew’s target is the lowest-risk reachable landing site. Sometimes that is a runway with emergency services ready. Sometimes the runway math does not work, and the crew chooses water or a reachable open area.

When A Runway Works

A long runway with a clear approach path is the best match. Crews often plan a slightly high pattern so they can use height to fine-tune the aim point. Low, flat approaches can be risky because there’s no thrust to arrest sink in the last seconds.

When Water Or Open Land Wins

Water landings and off-airport touchdowns carry hazards like waves, obstacles, and difficult evacuation. Still, they can be the better choice when the nearest runway is not reachable. The goal stays the same: wings level near touchdown, controlled sink rate, and a plan for evacuation.

What Decides Glide Range In A Practical Way

People often ask, “How far can it glide?” A single number can mislead because weight, wind, and configuration matter. The factors below give a clearer picture of what drives range and what crews do about it.

Factor	What It Does	What Crews Do
Starting altitude	More height gives more time and miles	Turn early toward the best reachable site
Wind	Tailwind adds ground miles; headwind steals them	Pick runway direction and plan turn points
Configuration	Gear and flaps add drag and cut range	Stay clean until landing is assured
Turns and bank	More bank raises drag and sink	Keep turns smooth; avoid steep banks
Weight	Changes target speed and descent profile	Use speeds tied to current weight
System status	Power limits can reduce instruments	Start APU or use backup power if fitted
Terrain and obstacles	Detours cost height and time	Choose straight-in paths when available

Passenger Actions That Help In A Fast-Run Evacuation

If you ever face an emergency landing, the basics make a difference.

• Listen and move: follow crew commands right away.
• Brace: use the brace position shown on the safety card.
• Leave bags: carry-ons can jam aisles and damage slides.
• Watch your step: use handholds and keep moving away from the airplane.

Clear Takeaway For Travelers

A plane with both engines not producing thrust can still fly in the sense that it can glide under full control. The crew will guard speed, try relights, use backup power, and steer toward the safest reachable landing site. The outcome depends on altitude, wind, and what’s within range at that moment.
