Problem statement :  Further to 295), 397), 620) ...further to as envisaged ...ability to takeoff and land
                     even in zero visibility to the human eye.

Opportunity :

           The following proposition could potentially be exploited in evolving a
           better communication or identification of airstrips and design of aircraft landing equipment.

           a) understanding of how the range or vicinity within which a remote-control hand-held device
              works for a Television.

           b) Ability to generate a detectable magnetic field over the runway or airstrip 

              ...by having magnetic field generators ....on the both edges or sides along the course of runway or airstrip ... alley,

              ability to detect any objects or obstacle on such runway or airstrips 

              ...that is ability to compute or diagnose the readiness or being prepared 
                 to takeoff or land on such runway or airstrip 

              ...say usage of doppler effect or other such scientific thesis ...say ...sound echo

               


Note: The above problem statement having been encountered in various scenarios
      and detailed in various 'Proof of concepts' as mentioned in

        ....apply appropriate
      'use-case' modeling, rationalize and arrive at a workable and feasible 
       solution both commercially and techinically viable.
