FLYHT Weather Observations is a solution that leverages our patented TAMDAR sensor system as well as AMDAR-over-AFIRS which both collect real-time weather. This application will provide customers with weather observations as well as icing and turbulence.
Provided as an integrated solution to FLYHTMap, our Weather Observations product visually renders weather data with flight information. The interface provides access to the “soundings” page, which shows Skew-T diagrams generated from both ascent and descent of equipped aircraft.
The TAMDAR observations data feed is available to users to ingest airborne meteorological observations into their own weather models.
TAMDAR reporting intervals are fully configurable. Our typical reporting intervals are 50 hPa during takeoff and landing, with the exception of just after takeoff and just before landing when TAMDAR delivers 10 observations at intervals of 10 hPa. During cruise, if TAMDAR is not experiencing significant changes in pressure, then a report is generated every 3 minutes when it is below a pressure altitude of 20,000 ft and every 7 minutes when above 20,000 ft.
The TAMDAR weather observations feed includes the following parameters:
The TAMDAR sensor estimates atmospheric turbulence reported as an eddy dissipation rate (EDR). This is calculated based on the true airspeed from the TAMDAR pitot and static port pressures and TAMDAR temperature. TAMDAR EDR report includes the mean and peak EDR and the time of the peak for each one-minute period.
The TAMDAR Turbulence feed includes the following parameters:
FLYHTMap allows users to view individual TAMDAR weather observations and turbulence while also tracking TAMDAR equipped flights.
The AMDAR-over-AFIRS data does not currently have relative humidity, icing, turbulence index or time of occurrence of peak eddy dissipation. Turbulence is something we would like to add in the future, but not currently offered.
The AMDAR-over-AFIRS weather observations feed included the following parameters:
Soundings are generated for each ascent and descent of a TAMDAR equipped airplane at nearly 200 airports across the globe. Meteorologists use these soundings to evaluate changing conditions such as frontal passages and potential for severe weather. The Skew-T Viewer application allows the user to view multiple soundings on one plot to see how conditions are evolving. Severe weather indices such as shear, CAPE, and helicity are available.
