Turbulence and Weather Management in Commercial Aviation


Yamasee’s goal is delivery of accurate real-time weather, based on crowdsourcing. Yamasee has developed the "Skypath" app that presents real time turbulence conditions, enabling airline planners and pilots to optimally and economically evade turbulent conditions.


Yamasee’s commitment to provide real-time data combined with aviation expertise enables the company to offer an optimal solution for turbulence.


The turbulence problem costs airline hundreds of millions of dollars due to crew and passenger injuries, operational delays, and unscheduled aircraft maintenance. For over 30 years the aviation community is trying to come to grips with CAT (Clear Air Turbulence). The available data is cumbersome, elusive and unreliable in telling the pilots what to do.


A Crowd Sourcing, network based system, using accelerometer and GPS data from tablets and other mobile devices - transmitting real-time data from the air - to a server and back to users. Safety of flight is a major focus - Skypath operates in the background and will alert the pilots ahead of time-without compromising safety of flight.

Real Time

An automatic real-time turbulence “sense and display” system

Safety First

Allows pilots to choose an optimal route keeping passengers safe 


Based on sharing crowdsourced information detected in real time

Plug n Play

Skypath could be installed easily , quickly and for not extra set up cost.
