This is my first year that I've been avidly shooting airliner pix (I got my Digital Rebel in December) and I'm having a real bear of a time with heat haze. Now, I know the conventional answer to avoiding this condition is to avoid shooting when it's hot. Photography on sunny, hot days between around 11 a.m. and 3 p.m. has obviously caused me a good bit of grief, but this is to be expected. However, a whole batch of shots I took recently at Bradley Airport in Connecticut came out horribly from heat haze - and these were taken at around 10 a.m. on a day that wasn't really all that hot, around 65 degrees F or so with some clouds. I've had heat haze ruin pictures when it was 20 degrees F outside. I have a Canon 75-300mm IS zoom, and the magnification really seems to intensify the heat haze effect. I've even had aerial shots destroyed by the effect - I stood in a parking lot near JFK to shoot Runway 13L arrivals a few weeks ago, and the heat haze was ridiculous. Other than to restrict my photography to very early morning or very late afternoon hours, are there any tips to avoiding this condition?

As has been pointed out before, its not the air temperature that's critical, its the difference between the ground and the air - eg. tarmac, absorbing the suns energy will heat up rapidly generating heat distortion in the surrounding air.
Yes, telephoto lens will intensify the effect - no way around it.
Avoidance - condition is worse on still days - a stiff breeze helps disipate the effect.
Try and minimise the amount of tarmac between you and your subject ... the middle of a parking lot sounds like the worst possible location
If you can find a grassy field and not have to shoot across any taxi ways I think you'll have a lot more success.

Well... I always go home when I encounter heat-haze, but I live very near the airport. The best way to get rid of it is by using as little zoom as possible. It's not as apparant then. And perhaps you can shoot planes on approach so you won't get the heat from the tarmac. (although heathaze will still be there, but less strong)

John, you have my sympathies ... plenty of heat haze here as well. As Colin said, the more wind the less likely is heat haze. I also like to shoot in the very early morning when the sunrays aren't too bright yet & in the last hour before sunset (& of course afterwards). Of course you'll need much higher ISO speeds &/or an IS.

If the aircraft is moving, why not practice your slow shutter speed motion blur shots? Since the subject is moving, the heat haze should be blurred like the rest of the background and foreground.
Interesting suggestion ... I have to try that out next time.

recently had Glenn Stewart over and took him out on a rather warm 42C day, he fully learnt the meaning of heat haze when he came to Perth, seriously here in Perth you can't even get final approach shots due to the intense heat haze! it starts at about 7am here in summer and usually sticks around the whole day!
in cooler months here it's just as bad, 16C day with sun will still produce enough heat haze to ruin your photos, i just try to avoid it all together by staying home or go and shoot between 5:30-8:00 am.

I have noticed here at DFW that the temperature inversion (heat haze) is also much worse when the humidity is high or the ground around the runways is wet or saturated. I see this effect all the time, even on cloudy days. In fact, most days here are useless as far as runway arrival and departure images. As a general rule, the inversion will stabilize late in the day after the ground and air temps have equalized, however, with high humidity the problem will sometimes persist until sunset.
