Right on dunbar, what a lot of bull
If we start getting such reports and such comments ......
Yes TCAS is very bad in azimuth ( within + and min 11 degrees )and you definitively cannot rely on it to assert positions. but that does not mean that in perfect conditions the display will always be wrong. And the " heading 220 " in a stressed voice ! Ah! personally I never met a unstressed japanese colleague did you ?
Advice : if you do not know what you are talking about, just read and keep away from the keyboard.
( maybe that should become the motto of this forum !)
