The determination of landing distance required for aircraft to land is calculated by taking into account the effect of various influencing factors, including **runway construction, surface conditions and the use of aircraft devices which are available to assist deceleration**.

## What does landing distance required mean?

Actual landing distance is the distance used in landing and braking to a complete stop (on a dry runway) after crossing the runway threshold at 50 feet; and, • Required landing distance is **the distance derived by applying a factor to the actual landing distance**.

## What is the factored landing distance formula?

The factored landing distance is **the certified landing distance multiplied by 1.67**, which can then be compared directly to the available landing distance.

## What are the factors affecting takeoff and landing distance?

They apply various factors, including **density altitude, type of operation, runway surface, runway slope and wind** to readily determine take-off and landing distances for a particular set of conditions.

## What are the four factors that affect flight and landing?

Four forces affect an airplane while it is flying: **weight, thrust, drag and lift**. See how they work when you do these activities as demonstrations.

## What is the difference between factored and unfactored landing distance?

**Unfactored landing distances assume precise control; factored landing distances reflect the effects of deviating from an ideal landing profile**.

## What is the P factor during landing?

P-Factor. P-Factor, which is also called "asymmetric propeller loading", **happens when the downward moving propeller blade takes a bigger "bite" of air than the upward moving blade**.

## What is landing distance required based on?

## What is factored and unfactored landing distance?

Unfactored landing distances assume precise control; **factored landing distances reflect the effects of deviating from an ideal landing profile**.

## How do pilots calculate landing?

When it comes to calculating the landing distance, it's not as simple as just plugging in the landing weight and coming up with a number. The major elements which affect the landing distance are: **aircraft weight, flap setting, wind, runway surface and runway slope**.

## How do airports decide take off and landing runway?

**Weather, in particular wind speed and direction**, is usually the main reason for selecting which runways are used at an airport, the direction aircraft take-off and land, and the flight paths that are used.

## What factors affect takeoff and landing distance?

**In general the LDR depends on a number of factors, principally:**

- The aircraft landing mass;
- The surface wind and temperature;<
- The runway elevation and slope;
- The runway surface conditions (dry, wet, slippery or contaminated); and,
- The condition of aircraft wheel-brakes and braking systems.
- The approach speed increment<

## What are factored vs unfactored loads?

A factored load is a load multiplied by a certain factor designated by codes of practice to drermine the strength of a structural members such as reinforced concrete. Unfactored load is a service load to determine the working stress of a structural concrete, steel, or wood member.

## Is factored or unfactored loading for deflection?

Note that a deflection controlled member should be identical with ASD versus LRFD, since **unfactored loads are used for deflection calculations**. Note also that compression per- pendicular to grain uses a different KF factor, so this analysis would show different results for bearing controlled applications.
