All The Information About Runway Analysis

By Ina Hunt


It is very important to ensure that your plane is not overweight when you are preparing for takeoff. It is also vital to ensure that you do not leave payload. You should confirm that field length calculations are perfect. You should ensure that a runway analysis is complete so that all the factors are well taken care of. All the calculations are intended to evaluate the landing and takeoff weights.

This calculation uses two main elements. The fist being AMF performance data and the second being runway and obstacle data. When these two parameters are available it is possible to prepare a complete analysis to determine the necessary weights. AMF data is required by airworthiness standards and specific requirements are defined in the flight test section. These data is usually collected during the flight test phase of certification.

Runway inspection helps to determine the maximum takeoff that is allowable for the conditions that are at the airport for the right takeoff speeds and different configurations on the airplane. The limitations observed are specified by the Airplane Flight Manual for the plane as well as the FAA. The information that has been analyzed is always provided in form of a manual. This manual contains a complete description of all the airports that the plane is designed to fly to.

The data for the airports is taken from a database that is worldwide. It is compiled from industry and government sources. These kind of calculations are very important for the purpose of planning. They are provided when they are needed. The calculations can be obtained by the customers when they need the data. They can get a paper copy or they can get the information through the internet.

There are several factors that are used to determine the max weight allowed. The first of these factors is the greatest weight allowed for takeoff. In other words this is the structural limit. Climb limited weight is also an important consideration. This refers to the weight at which some of the segments can be attained for the elevation as well as the temperature of the airport.

Another factor is the field length limited weight. This is the max weight at which the plane still meets the FAR rules governing the slope, elevation, length, wind and temperature of the airport. Obstruction limited weight is also a consideration. This is the obstruction required by FAR. The limited weight is a function of slope, elevation, temperature as well as distance, wind and height.

Unless it is specified in the calculations a straight out flight path is assumed as the clearance for obstruction along the extended center line. Brake energy capacity is another characteristic that is evaluated. It is evaluated to ensure that weights shown after the calculations are compliant with the limitations of the brake energy.

The final factor to place into consideration is the tire speed. This element ensures that the weights are in line with the tires limitations as far as speed is concerned. Calculations are designed to make tables that are used by customers to make procedures that reduce the thrust.
