TNIP RA - TNIP Runway Allocator

TNIP Runway Allocator is a tool which enables the user to predict which runways will be used at an airport. Its prime purpose is to generate predictive data files which facilitate the generation of time stamped aircraft noise information that goes beyond the conventional annual average day description of future aircraft noise. However, broader applications for the concept are now emerging.

TNIP Runway Allocator uses detailed wind and aircraft movement datasets to allocate predicted aircraft movements to runways on a movement by movement basis. The methodology used by TNIP RA contrasts markedly with conventional approaches in that any averaging of data is carried out after movements have been allocated to runways not before as is the standard practice. The key features of the program include:

Simple user interface to enter airport operating parameters such as
- runway alignments
- crosswind/downwind criteria
- hierarchy of noise preferred runway modes for user selected time periods during the day
- movement capacity of the runway modes
- ATC behaviour in making runway selections.

What ifs and sensitivity analysis
- The airport parameters can be rapidly changed and the runway allocations re computed to explore what if scenarios and to ascertain the sensitivity of the runway use projections to variations in the airport operating parameters.

Reports
- The program contains a number of pre formatted reports which give information on allocation outcomes and data status
- User defined reports can be produced through the use of standard MS Access queries.

Output files
- The prime output of the program is files containing aircraft movement datasets which have all movements allocated to runways. These files can be exported
  - as time stamped data files for direct use within TNIP to produce flight path movement and respite charts and indicative noise contours
  - as 'average day' data files in .csv format files which can be opened in Excel or other spreadsheets applications; these can be used as input into INM studies to produce conventional noise contours

In an environmental assessment the program is run iteratively with past year wind data sets to build up a 'composite year' rather than an 'average day'. The composite year contains time stamped information on every movement at the airport over say a notional ten year period. The composite year can be used either in TNIP or INM.

TNIP Runway Allocator has been written in MS Access 2003, however, an MS Access 2002 executable has been generated and is available for down load here. TNIP Runway Allocator v2.1 [ZIP: 4829 KB] Enhancements added to v1.0 comprise Numerous user interface refinements Routines for checking the integrity of data during the loading process Optimisation of the code - v2.0 is significantly faster than v1.0 A powerful search/filter tool for examining both actual and computed data sets Problems handling wind files with leap years have been corrected While the Runway Allocator can be setup for any airport this version of the program has been preloaded with the airport setup for Sydney Australia and has a small sample of preloaded data. If MS Access 2002 or higher is not installed on your computer you must install the MS Access 2003 runtime files first in order to run the program. A copy of the Runway Allocator with the MS Access 2003 runtime files included will be available for download soon.

TNIP Runway Allocator v2.2 Beta [ZIP: 5145 KB] Major enhancements have been made to the Runway Allocator and, while they are still under development, a working beta version is now ready to be released. Beta enhancements added to v2.1 comprise Tighter integration with scenario files and runway assignment; cycle through an archive file and assign runway for the entire archive, results are saved for use later History reporting now offers flexible viewing and comparison of previously saved runway assignments Improvements and additions to the search/filter tool and save points Simplification of archives; build and manage new and existing archives Improved data loading, the addition of tools for specific data problems Minor bug fixes

The Department presented a paper to the International Congress and Exposition on Noise Control Engineering (INTER-NOISE 2006). This paper gave a background to the work the department has been doing concerning the implementation of strategies related to aircraft noise which have moved beyond the use of 'Average Day' and used 'time stamping' for accurate noise prediction.
