Learn the safe airliner touchdown rate, why 100–300 fpm is a useful target, and when a firm arrival needs a hard-landing assessment.
In real-world aviation and airliner simulation, a safe touchdown is normally a controlled, positive arrival at roughly 100–300 feet per minute, in the touchdown zone and within pitch, bank and speed limits. No universal maximum exists: aircraft type, landing weight, runway condition and actual impact loads matter more than one feet-per-minute reading.
What touchdown rate should an airliner aim for?
About 100–300 fpm is a useful practical target for a conventional main-gear touchdown, but it is not an operating limit. The aim is to reduce the approach sink rate during the flare without floating, ballooning or forcing the aircraft onto the runway.
These approximate coaching ranges help interpret simulator results:
| Reported touchdown rate | Practical interpretation |
|---|---|
| Under 100 fpm | Very soft. Excellent if achieved in the touchdown zone, but it may indicate an extended float. |
| 100–300 fpm | Normal controlled touchdown range for routine simulator training. |
| 300–600 fpm | Firm and increasingly concerning. Check approach stability, landing attitude, touchdown position and recorded loads. |
| Over 600 fpm | Potential hard landing. Treat it as a warning requiring type-specific assessment, not as an automatic structural verdict. |
These are not manufacturer limits. An aircraft can touch down gently but unsafely beyond the touchdown zone, or land firmly yet safely on speed and near the aiming point.
How is touchdown rate different from approach descent rate?
The aircraft’s descent rate on final approach is much higher than its vertical speed at touchdown because the flare arrests part of that descent.
On a 3-degree path, a quick estimate is groundspeed multiplied by five. At 140 knots groundspeed, that is about 700 fpm before the flare. Our guide to calculating the correct final-approach sink rate explains how wind and glide angle affect that figure.
Touching down near the full approach sink rate usually means the flare was late, too small or absent. Trying to eliminate all vertical speed can cause the opposite problem: a long float followed by a late landing.
Why is a very soft landing not always safer?
A very soft touchdown becomes unsafe when achieving it consumes too much runway or delays weight-on-wheels systems.
Airliners need positive main-wheel contact so the wheels spin up and the ground spoilers, autobrakes and other landing logic can operate as designed. This matters particularly on wet or contaminated runways, where a deliberate touchdown in the correct zone is preferable to a prolonged attempt to produce a low landing-rate score.
A mistake we see constantly in simulators is holding the aircraft inches above the runway while speed decays. Use the correct flare, maintain the landing attitude and accept a controlled touchdown; our advice on smoother landings without excessive floating covers the technique in detail.
When does a firm touchdown become a hard landing?
A hard landing is determined using aircraft-specific loads, event data and inspection criteria—not one universal feet-per-minute threshold.
The assessment may consider:
- aircraft weight and vertical acceleration;
- pitch and bank angle at contact;
- whether one main gear struck before the other;
- runway slope and surface condition;
- gear compression, rebound and subsequent nose-gear contact;
- crew reports and recorded flight data.
Transport-aircraft certification figures are sometimes misquoted as proof that any touchdown up to 600 fpm is safe. Certification landing-gear load cases use specified descent velocities under defined assumptions; they are not operational targets or universal hard-landing triggers. A real operator follows the aircraft manufacturer’s reporting and maintenance procedures whenever a hard landing is suspected.
How reliable are simulator touchdown-rate readings?
Simulator landing-rate figures are useful for spotting trends, but they are estimates rather than structural assessments.
Different tools may sample vertical speed immediately before contact, at the first main-wheel contact or after both main gears are down. Runway slope, frame rate, gear animation and one-wheel crosswind touchdowns can therefore produce different results for the same landing. In Microsoft Flight Simulator, our explanation of how landing-rate tools report touchdown performance shows why the number must be read alongside speed, alignment and touchdown position.
Judge the whole arrival: a stabilised approach, correct speed, main-gear-first contact, suitable pitch and bank, touchdown inside the proper zone and controlled nose-wheel lowering. If those elements are wrong, a flattering 50-fpm result does not make the landing safe.
