Siouxsie,
Thanks for your reaction! My question is not ment to doubt the FRC's and moreover the theory behind to which I for sure agree. In our (RNLN)Lynx fleet the cyclic markings were not always used as strictly as promulgated nowadays. Moreover the MPOG markings and the use of them were introduced in 1991. Therefore I'm still interested in the applied procedure of past and present Lynx pilot's.
