Airplane location in 1930
 

Do can be useful today for found sites of crashes (for small airplanes)?

Buena idea Esteban!
I am going to post this on Rc forum :)

Good idea for RC's, how a bout a small dye pack for water crashes?

Maybe some old ideas can be useful... or re-invented! :lol:

For water crashes I think that the pilot can launch a kind of mini-misile with short range wich floating in water and emit code via radio at very low frequency. No many efforts the aviation company puts in these methods. The black box is only for record, but not is useful fo to locate the plane. When occurs in water is extremely difficult to locate.

OK, go ahead! :)

Hi Esteban,
I think VLF underwater will be almost impossible to localise.They use ultrasound instead for the boxes.
Dye also will not work too well if the plane is deep , there is strong currents that will take it away, and something must bring it to the surface.

Radio location.

The most of times knows the approximative position of the plane, so the rescue team can locate ease the plane in the water (or submerged on it) via the radio emission.
