Aircraft Approach
and Departure
Atmospheric
Profile Generation Algorithm
Quality measurements of static temperature, wind speed,
wind direction, and eddy dissipation rate (EDR) for approach
and departure corridors are not available for aircraft wake
vortex measurement systems.
|
| AeroTech
has developed an algorithm that enables properly equipped
aircraft on approach to or departing from an airfield to
make measurements of these parameters of interest throughout
the airport's airspace well above a sensor tower altitude.
These measurements are based on an altitude and therefore
can be used to build a profile of the atmospheric conditions
surrounding an airfield.
|
|
| The algorithm uses a sliding
statistics window within the region of interest to generate
the profiles of the key meteorological parameters (wind speed,
wind direction, temperature, and EDR). The algorithm was
developed to provide the meteorological profiles as inputs
to the NASA Wake Vortex
Advisory System (WakeVAS), which is in development. |

B757-200 data, see NASA Contractor Report, NASA/CR-2004-213236,
