I am the Head of Training of a Flight Academy in Greece and we use your site for our flight preparation and briefings.
During summertime , some days have a high discomfort index, meaning that we are restricted to fly.
Since you have Temperature and Humidity figures , is it possible to create a DI selection/option based on the formula
DI = T - 0.55 x ( 1 - 0.01 RH ) x ( T - 14.5 ) ??

Thanks
