Knowing the focal length and camera used might be able to give a distance, but obviously couldn't be used to find the height.

I am not looking for an exact number, just an idea. You could get it in the ballpark.

What I mean to say is that it would tell you AT MOST what the altitude would be. Any angle of declination would obviously make it closer to the ground, than that.

The guy could easily lose his license over just this incident. So if you are going to do it to this guy, get good evidence that he is actually fucking up.

Why not just believe that a) Lee thought it was obnoxiously low and b) the FAA is used to dealing with the general public giving bad eyeball estimates of altitude? The guy is not going to lose his certificate over one complaint with no evidence. If he's got a history, or does it again and someone does snap a good pic to show he's way too low, then this complaint helps keep one jackass out of the air. |

Math is not hard people..... This is a discussion forum. Let's discuss it. It's boring as shit when you just have a lynch mob mentality about everything....

Lodge a complaint and move on. Fucking whiner. Edit: I guess, he could lose his license. Double edit: My guesstimate off of a picture is better than Lee's first hand experience. /Trip |

Guess number 2, based on zero reference points available in the photo. Based on these two guesses, you're going to come up with something more accurate than Lee, who estimated one distance, in person, in 3-D. Quote:

Good grief man, if you came across any more empty-headed in this thread I'd swear you could fail a CT scan. |

You could easily get information off the plane itself about scaling, that combined with information from the camera itself aka zoom,lens, and such you can easily determine distance from the camera to the plane. Sometimes you can even get this information from the photo itself depending on what the camera embeds into the digital photos. Some cameras will even embed GPS info into photos nowadays. Using that distance, you can use a wide array of angles from the ground to that of the photo taken. Then using simple trig based on those two determinations, you can get the height of the airplane Math is not fucking hard if you aren't a dumbass like yourself. BTW a person on the ground using his naked eye that has no education on identifying the altitude of airplanes is making an uneducated guess. We aren't going to be looking for accuracy of inches, by probably tens of feet. Which would be a very well reasoned estimation.
