November 2, 201114 yr Hi,Anybody who have an ideer because i have now 2 times in a row not being able to fly LNAV. Only Heading (which is fun btw :-)First timer for this to happened.Have SP1 and the expansion pack/michael Moe Michael Moe
November 2, 201114 yr Just out of interest are you correctly set up in the FMC and on the right heading in order to activate the LNAV ?
November 2, 201114 yr Author YepBut the strange thing is that it says LNAV/VNAV (white info on the PFD) but is only flying Heading and NO light in LNAV butoon on MCP/Michael Moe Michael Moe
November 2, 201114 yr Author Hmm maybe it has something to do with the IRS alignment.When looking in the POS REF page 2 there is no IRS L coordinates ?I remember that i did overtyped the IRS alignment with the GATE POS in the alignment /Michael Moe Michael Moe
