US Markets Loading Typically, a crosswind of around 40 miles per hour and a tailwind of 10 miles per hour are the upper limits for a safe takeoff and landing.

More specifically, the slope angle is the total change in height of the runway over the total length of the runway. Planes on runways with a downward slope negative will take off more quickly. On the other hand, planes taking off of runways with an upward slope positive will take more time to take off.

When landing, the reverse is true: planes landing on a runway with an upward slope will land more quickly. The uphill climb will slow the plane down gradually as it lands.

But on a downward slope, the plane will take longer to land. The best material for runways is concrete. This helps the tires roll with little to no resistance. At smaller airports, you might see gravel or grass on runways. But, the tires can sink into the surface on grassy runways, slowing takeoff speed. But it works fine for smaller planes. Some runways have grooves, by design. Also, the water sinks into the grooves, too. Over time, a runway experiences wear and tear and may accumulate some holes or divots.

These can keep the tires from gliding smoothly and interfere with takeoff. The tires also can get pretty beat up, as the rubber sheds off onto the runway surface. Ideally, this is cleaned off before takeoff and landing but not all airport runways are maintained as best as possible. If the tires are not cleared from the runway, they can sink into the grooves, allowing standing water to accumulate.

This may prevent planes from having a smooth takeoff. Some private jets require as little as feet of runway. They have compact designs, which make them more versatile than other long-range jets. Comparably, commercial aircraft require significant runway space to take off or land, typically a minimum of 4, feet and a max of up to 13, feet or more.

I recently read this article that talks about s taking off from Princess Juliana International Airport in Sint Maarten. The Princess Juliana runway is only 7, ft, but according to Wikipedia , the needs more than 10, ft of runway for take-off.

And as Terry pointed out, "ambient temperature also enters in. The cooler the air is, the more you can lift. You would have to go the the manufacturer approved performance charts for this as opposed to Wikipedia as I don't really know where the author obtained that.
