After looking in the screenshots forum..I don't suppose the PMDG 737 can produce wing tip vortices? I haven't seen any yet. Will the B744 have these? They look really 'neat', probably at the cost of frame rates. Perhaps they were just edited in??Also, PMDG please read p2 forums 'Small Transition Problem' - possibly a bug?Goodnight or Goodmorning ;)Geoffrey BaleanCanberra, AU (YSCB)http://www.hifisim.com/images/as2004proudsupporter.jpg http://www.precisionmanuals.com/images/forum/800driver.jpg"Today is the tomorrow you worried about yesterday.

Geoffrey,Wing tip vortices are not normally visible. The only time you might see them is during landing on an extremly humid day or when passing through a cloud. These would only be intermittent.Tom
