|The simplest answer: for an average-sized commercial jetliner with typical fuel and payload, the "takeoff speed" is around 130-160 knots, or about 150 to 200 miles per hour. The landing speed is more or less the same, usually a few knots slower. |
Although density altitude is not a common subject for “hangar flying” discussions, pilots need to understand this
topic. Density altitude has a significant (and inescapable) influence on aircraft and engine performance, so every
pilot needs to thoroughly understand its effects. Hot, high, and humid weather conditions can cause a routine
takeoff or landing to become an accident in less time than it takes to tell about it.
