Track Shortening
Flying between A,to F middle of the day and request track shortening on centre from B to E . Due to high headwind . Will advise was the response . Ask again 15 mins later advised can't do due to crossing traffic . Fair enough . Just for fun we selected each TCAS monitor 1 above and 2 below this gives us 9500ft above and below cruise level total 19000 ft coverage cruising FL410 and range out to 120 nm . As part of an avionics upgrade approx a hundred odd grand we received ADSB . over the next 2 hrs we spotted only 1 other a/c on our TCAS which was 3000 ft below and approx 80 nm away never crossed our track . Whats the point of doing ADSB ? This is NOT a dig at ATC but a question of return for investment , cost to aviation companies/ owners and how will Airservices use these improvements to help the industry .
