All The Information About Runway Analysis

By Ina Hunt


If you are ready for takeoff you need to ensure that your takeoff is not overweight. You need to make sure that you are not leaving payload behind. It is also important to make sure the field length calculations are correct. To make sure that all these factors are in order then you need to have a runway analysis done. This is a calculation to determine the takeoff and landing weights.

These calculations utilize two elements. The first component is referred to as AMF performance data and the other element is runway and obstacle data. If you have these two components then all the right weights can be determined. AMF performance data is usually necessary for airworthiness standards to be met. The requirements which are specific are well explained in the flight test section. All these information is usually taken during the flight test stage of the 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.

There are worldwide databases that are used to get all necessary information about airports. This database is compiled using government files and industry sources. Planning relies on this kind of information. This data is always available to those who need it. Customers can access the information if they need it. They can rely on two options to access the information. They can either use the internet or get a paper in hard copy.

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.

The clearance for the obstruction on the center line which is extended is always taken as straight out flight path unless stated otherwise. Another characteristic you need to factor in is the capacity of the brake energy. This factor is used to show that calculations are in line with the brake energy limitations.

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.
