I think that a light heat haze coming out of aircraft engines would add a great amount of realism to Infinite Flight. This has already been implemented into PC systems like X-Plane 11 and adds a HUGE sense realism specially when taxiing and taking off.
Below Are Some Real Pictures Of Engine Heat Haze Coming Out Of Various Aircraft:
This is an image of heat haze implemented in Xplane-11 on a Boeing 737-800:
What Causes Heat Haze?
Heat haze is caused by refraction from the more dense, cooler air, to the less dense, hot air and the transfer of heat energy. Refraction is the bending of light, due to changes in substance density or, a materials, physical property. Similar to the way light shimmers in a pool, light passing through the fast hot air, gets bent and appears to move fluently. The transfer of heat (from the hot air to the cooler air) causes light to bend as well.
Why add Heat Haze?
At almost any point in time, heat can be seen coming out of a turbine or a jet engine. Adding this effect will dramatically increase the realism and will help portray the power and beauty behind the turbine engine. After all who wouldn’t want something like this in IF?
