Searching for crashed aircraft in the forest

[avcrashfinder]

Is equipment available to search for old crashed aircraft in the forest, either using a friends airplane or hiring someone to do it? Please email me at [email protected]. Thanks!

you can use good PI detectors with large coil , if you have alot of money and you can use of a cobra or sir gpr. but searching with pi is more easy .
a 2box detector with auto tracking like TF900 discovery is good .

but i suggest you put your money in bank and build a delta pulse and the go to aircraft hunting .

oh , i forget maybe HUNG or MORGAN could find your aircraft through the mountains from many miles away , if the pilot of the crashed aircraft put his wedding ring.( they have a secret pistol that bring from Mars)

I don´t think he was talking about a lost model RC airplane

Thanks Fred. I'm talking about a real airplane in a real forest. It has to do with locating a friend's aircraft that has crashed and has not been found. I'm not speaking of a hobby type thing but of a real need to find a downed aircraft and possibly survivors. I know that they us aircraft to "explore" for underground minerals and so forth, but is there technology and equipment to put into an aircraft to find a pile of aluminum under dense foliage? Maybe that's not the kind of thing folks on this forum are involved in and if so I'll go away. Thanks!!

A lot depends on how big an area, what type of aircraft and how long ago. It can also depend on how dense the growth above the crash is. There are options but most would need to operate from a slower platform then another airplane.

How much info is available on the suspected crash? Was it seen on radar just before contact was lost? Were there any signals from an emergency beacon?

sorry avcrashfinder, first i guess you try to find a crashed plane from WW2 or something else .

in geophysics remote sensing there was methods and devices for scanning area but with size of a aircraft it's so difficult , most of them use magnetometer , and for your reason most of aircraft is Aluminum and magnetometer is not so good , i heard about some military satellites that their works is finding hidden military stuffs , try to help from army .

i wish the people in the aircraft be alive and survive soon

Thanks for the two most recent responses. I was not very specific with my information. It is a smaller, twin engine aircraft, so it would be aluminum. The forest is extremely dense with a couple of layers of canopy. The search area is nearly 50 square miles based on their last known position. There were some signals from an emergency locator transmitter but searchers were not able to pinpoint the site from them because the signals were weak and were apparently bouncing around from rough terrain. It is approaching a month since the crash and hope for survivors is dimming. At the very least it would be helpful for those close to the crew, to be able to bring closure to the situation. From several of your responses it doesn't appear that finding the wreckage from the air, using metal detecting equipment, is a viable option. Thanks for your prayers and well wishes and I'll advise if they are found.

Those are the bad conditions for a search. But, having been involved in many searches over the years, I would make a suggestion.

Aluminum is not a good metal for a magnetometer, which would be the only metal detection method that would be useful for a search from the air above a canopy like this. But, one property of aluminum that can help is its rapid heat conduction. I would talk to a company that has FLIR infrared cameras mounted on helicopters. Design a search that would be done on an evening when the temperature is going to have a swing of at least 20 degrees, for this more is better.

The aluminum will give up heat much faster then the ground around it so there is a chance that they may be able to see the difference on the FLIR display. It is still a lot of area to cover and that is a small target that is well masked but I think you should explore the option. Just find a company that has a good track record with that type of search before committing because there is a big difference in having the equipment and being proficient in its use. I would contact someone Here and ask for a list of contractors in the area that they feel could do the job.

Best wishes for a quick and safe recovery and prayers for the families to be reunited soon,
Rip

Hi,
Did you consider motor paragliders ? could fly slow and low enought to find some marks that a crashing airplane must have done.Could also shut engine off from time to time to listen...
Good luck,
fred.

[avcrashfinder]

Thanks for the idea Fred. Because of the remoteness of the area and the hostile nature of the terrain a motor paraglider would probably not work. I deeply appreciate your offering such a suggestion though.

[avcrashfinder]

Thanks Rip. I have passed those thoughts on to the persons who are involved in the search.
