What Is a Forced Landing? A Pilot’s Guide to Landing Without Power

A forced landing is an emergency landing you make right now, with no engine power and no choice about whether to go down — your engine has quit or is failing, and you are committing the airplane to the ground at the best site you can reach in a controlled glide. That’s different from a precautionary landing, where the engine still runs and you choose to put down early. The forced landing is drilled into every student pilot because the order you do things in decides how it ends.

Most pilots fly a whole career and never need this for real. We still drill it on every checkride and flight review because when the engine goes quiet, there’s no time to start learning. You either have a flow that runs on muscle memory, or you fixate on the dead engine and ride a perfectly flyable airplane into something hard. This guide covers what a forced landing is, the FAA procedure behind it, and the mistakes that turn a survivable event bad.

What is a forced landing?

A forced landing is an emergency landing made when the engine has failed or can no longer produce usable power, forcing the airplane to the ground at an unplanned site under glide alone. The pilot doesn’t choose whether to land — the failure decides — and the only decisions left are airspeed control, site selection, and the order of the response. The Airplane Flying Handbook (AFH, FAA-H-8083-3C) treats this as a core emergency competency.

The word “forced” is doing real work. You’re not picking a nicer alternate airport or flying ten more minutes to a paved runway. The engine quit, the airplane is now a glider, and physics will put you on the surface within a couple of minutes whether you have a plan or not. That’s why instructors are relentless about it — a forced landing strips away every comfortable option and leaves you with the fundamentals: pitch for airspeed, find somewhere survivable, and fly the airplane all the way to the ground.

How is a forced landing different from a precautionary landing?

A forced landing happens when the engine has already failed and you have no power, so landing off-airport is mandatory. A precautionary landing is a deliberate choice you make while the engine still runs — you land early because of weather, low fuel, lost bearings, or a rough-running engine, on terms you control. One is forced on you; the other you elect.

The distinction changes your timeline. In a precautionary landing you can circle, inspect the field, set up a stabilized approach, and use power to fine-tune the touchdown. In a forced landing you get one glide, one shot, no go-around. The AFH also describes a third category — ditching, a forced landing onto water — studied on its own because the survival considerations differ.

What do you do first when the engine quits?

The first action is always the same: pitch the airplane to establish and hold best glide speed. Before you touch a radio, troubleshoot the engine, or even fully process what happened, you trade altitude for the most efficient glide your airplane can fly. Flying the airplane comes before everything.

This is the step new pilots skip when adrenaline hits. The engine quits, the silence is loud, and the instinct is to stare at the gauges or grab the radio. Meanwhile the nose creeps up, the airplane bleeds toward a stall, and you’ve thrown away the altitude that was your only real asset.

Lock in the habit early: the instant power is lost, your hand sets the glide attitude, your eyes confirm the airspeed, and you trim it off so it holds hands-off. Now you’ve bought every second physics will allow, and you can think. Aviate, navigate, communicate — in that order. The engine failure doesn’t change the priority list; it just makes the cost of getting it wrong much higher.

What is best glide speed and why does it matter?

Best glide speed is the airspeed that gives you the greatest distance forward per foot of altitude lost — the most ground covered for the altitude you have. It’s published in your Pilot’s Operating Handbook. Flying faster or slower than best glide steepens your descent path and shrinks the patch of ground you can reach.

There’s a second speed worth knowing: minimum sink, a bit slower than best glide. It keeps you aloft the longest but doesn’t cover the most distance. Use best glide to stretch toward a field; consider minimum sink when you’re already over a usable site and want maximum time to run checklists.

Weight changes the numbers. Best glide in your POH is published at maximum gross weight, and a lighter airplane glides best a touch slower, though the glide ratio stays roughly the same — which is why glide performance (PLT006) shows up on the knowledge test. Two things wreck a glide fast: a windmilling propeller creates far more drag than a stopped one, and lowering flaps or gear early steepens your descent. Configure for landing only when you have the field made.

How do you pick a landing site?

Pick the largest, smoothest, most into-the-wind surface within gliding range, and commit to it early rather than chasing a perfect field you can’t reach. The AFH prioritizes survivability: a touchdown on rough ground beats a long stretch toward a beautiful field you fall short of. Wind, length, slope, and surface all factor in, but reachability comes first.

A useful mental checklist is the four S’s: Size (long enough to stop), Shape (favoring a landing into the wind), Surface (smooth, firm, free of large obstacles), and Slope (land uphill, never downhill into a rise). Add surroundings as a fifth — wires and trees at the approach and departure ends.

Roads tempt pilots and carry hidden hazards: power lines, signs, traffic, and a width that’s barely a wingspan up close. A plowed field, pasture, or open beach is often safer. Fly a recognizable pattern to your site when altitude allows so you can adjust the aim point with slips and flaps — and if you’re high with the field made, don’t dive at it. It’s far easier to throw away altitude than to manufacture it.

What is the forced-landing checklist flow?

The forced-landing flow runs in a fixed order: establish best glide, pick a field, attempt a restart, make your radio calls and brief passengers, then secure the airplane and commit to the landing. That sequence keeps the highest-survival actions first. The exact items live in your POH emergency checklist, but this priority structure is universal across light airplanes:

A few notes that save lives. The restart attempt is a quick scan of the common, fixable causes — fuel on the wrong tank, mixture pulled, carb ice, a mag switch knocked off. If nothing brings it back in a few seconds, stop troubleshooting and fly the approach; many off-airport accidents trace to a pilot heads-down chasing a restart while the airplane glided past the only good field. Securing the airplane reduces fire risk, cracking a door keeps it from jamming if the airframe deforms, and tightening every harness hard is one of the strongest predictors of walking away.

Building this flow into muscle memory is what structured training is for. Our free Total Student Pilot course introduces the aviate-navigate-communicate framework, and the full Private Pilot Ground School drills the emergency procedures, glide performance, and decision-making you’ll be tested on — and might one day need for real.

Chris’s engine-out drill over the Alaska bush

I learned how a forced landing really feels not from the engine quitting, but from a CFI who refused to warn me. We were in a 172 over the Alaska interior — spruce, gravel bars, the occasional ribbon of river — when he reached over mid-conversation and pulled the throttle to idle. No “ready?” No countdown. Just silence and a grin.

My first instinct was exactly the wrong one: I looked at him. He pointed at the airspeed indicator. Right — pitch for glide, trim it off, then think. The second I had the airplane settled at best glide, the panic drained out and the problem got small: where am I putting this?

Out there your options are honest. There’s no convenient field, so you learn to read a gravel bar for length and a river bend for wind, and you commit early because second-guessing costs you the only site you could reach. He let me fly it down to a few hundred feet before pushing the throttle back in. The lesson stuck harder than any briefing: the airplane flies beautifully without the engine, but only if your hands set the glide before your brain catches up.

I’ve taught it that way ever since — aviation education since 2006, a CFI since 2017. The students who internalize “airspeed first, field second, everything else after” are the ones I’d trust to handle the real thing on a day they never saw coming.

PLT Study Guide

The FAA tags knowledge-test questions with PLT (Pilot Learning Statement) codes. These are the codes that actually map to forced-landing content — study them in plain English so you can recognize the questions and fly the concepts.

PLT208 — Recall emergency conditions / procedures. The core code for forced landings. Know the fixed priority order — aviate (best glide), navigate (pick a field), communicate (squawk 7700, declare) — and the items in your airplane’s emergency checklist.

PLT006 — Calculate aircraft performance – glide. Work glide distance from altitude and glide ratio: how far can you reach from a given height? Best glide speed is published at gross weight, and a lighter airplane glides best slightly slower while keeping about the same glide ratio.

PLT210 — Recall engine shutdown – normal / abnormal / emergency / precautions. Know the common, fixable causes of power loss you scan during a restart — fuel selector, mixture, carb heat, magneto switch — and the securing steps (fuel off, mixture cutoff, mags off, master off) before an off-airport touchdown.

PLT170 — Recall approach / landing / taxiing techniques. Manage a power-off approach: fly a recognizable pattern to your chosen site, use slips and flaps to control altitude and aim point, and land into the wind on the most survivable surface available.

PLT394 — Recall regulations – declaration of an emergency. Under 14 CFR § 91.3, the pilot in command may deviate from any rule to the extent required to meet an in-flight emergency, and the FAA may request a written report. Declare with “mayday” and transponder code 7700.

Frequently Asked Questions

FROM CHRIS

Forced landings sound terrifying until you’ve practiced enough that the silence stops being scary. The pilots who handle them well aren’t braver — they’ve rehearsed the order of operations until it’s automatic. Airspeed first, field second, everything else after. Build that habit now, while the stakes are zero, so it’s there if the day ever comes.
