array data compression that is holding 13268 bits(1.66kBytes)

Question

i.e array is having 100*125 bits of data for each aircraft+8 ascii messages each of 12 characters what compression technique should i apply to such data

Answer 1

Depends mostly on what those 12500 bits look like, since that's the biggest part of your data. If there aren't any real patterns in it, or if they aren't byte-sized or word-sized patterns, "compressing" it may actually make it bigger, since almost every compression algorithm will add a small amount of extra data just to make decompression possible.
