Hi All,
I tried performing an ILS landing on Singapore WSSS 2L (ILS 110.90), but as soon as hit the APP button, the aircraft just turns around like it was blind to the ILS frequency (110.90 was set in the FMC and i had also manually tuned 110.90 on the NAV dial). I did notice that VOR LOC was activated on the EFIS prior to the turn around. I haven't encountered this problem with the JAR A320 & A330.
Hope you guys can provide some insight. Thank you.
