As well as helping the engineer to understand the feel of the car and physical effects of the changes that are being made, the simulator environment is also ideal to train both engineers and drivers in efficient communication. The simulator also allows the engineer to change positions with the driver in order to feel the effect or symptom the driver is explaining. This improvement in communication between driver and race engineer will be of definite benefit at the track.
The simulated environment gives the race engineer everything that would normally be available on a race day including track position with sector and lap times, live telemetry and TV Camera Style/Overhead overview of the car on the track. Simulator sessions will give the race engineer experience of efficiently digesting all of the presented information and relay only the important aspects back to the driver.
