737 intercepting LNAV while in HDG mode
Let’s say you’re in HDG mode and ATC tells you to intercept LNAV at an angle.
Under certain situations I’ve seen on engaging LNAV, the plane go to a steeper intercept angle.
For example, I turn the plane towards a 30 deg intercept in HDG mode and then engage LNAV..the plane will sometimes go to 40 or even steeper intercept…not something the atc wants.
I know one criterion is that the plane wings have to be level before engaging LNAV. But sometimes even that doesn’t work.
is there something else out there…like distance from course before LNAV can be engaged etc.
