Effects of atmospheric conditions, including wind and density altitude, on a go-around or rejected landing.
Bottom line
At high density altitude, the airplane lands at the same IAS as at sea level but with greater TAS, which increases landing distance. A go-around made close to the ground may be in ground effect, and the apparent performance gain is borrowed performance repaid when climbing out of ground effect.
Key numbers
| Number | What it means |
|---|---|
| 16% greater minimum landing distance than sea level | At 5,000 ft |
| ~21% landing distance increase | 10-kt tailwind |
| at least 21% landing distance increase | 10% fast |
