Narrative:
Once again on the cpt 3G departure off of 27L at egll; as we approached the (intc) waypoint; the next waypoint (D257G) went white and we received a scratchpad message 'not on intercept heading'; . This is the 3rd time in 6 weeks that has occurred in 3 different aircraft; all on the cpt 3G departure off of 27L. I have also performed 3 takeoffs off of 27R using the cpt 3F departure (with a much larger intercept turn) and have never had this occur.speaking with other pilots in london; they also have had this occur but never thought to file an fsap report.
