Hello Mr Ranganathan

I've supplied several systems to the aeronautical industry and have experience with
calculating
ETOPS with MapInfo. ETOPS stands for Extended-Range Twin-Engine Operations. It
basically
refers to the range a place can travel in a reduced engine capacity. In countries
where a flight plan
must be logged, a flight path must include at least one airport which is "in reach"
should an
emergency occur. An "ETOPS circle" can be calculated around an alternate airport by
multiplying
the air speed and time of the ETOPS rating (which varies from aircraft to aircraft and
changes as
the plane gets older). This gives a range in nautical miles which can be plotted
around each
alternative. For the flight path to have a complete set of alternates, every part of
the path must be
covered by one or more ETOPS circle. An important word of WARNING: MapInfo's buffer
function
just doesn't work properly with large distances - you have to write your own.
