I’m a little confused by this question on the IFR written:
I selected A, but the answer is C.
This was my thought process. It seemed obvious to me that “Baro NAV” was referring to the DA of 3100 feet for the “LNAV/VNAV” approach since “Baro NAV” relates to vertical guidance implied by VNAV. So, that eliminated B, and the answer must be A or C.
I then noticed that the side view specifically shows a point that is “1.5 NM to RWY 30,” along with the asterisked indication that it’s “LNAV Only.” And, based on the fact that the missed approach seems to depart more or less from that point, I answered A.
As already noted, however, the correct answer is C.
It't not at all obvious to me that the LNAV approach terminates at the RW30 waypoint.
Can someone explain this a bit? How would I know for sure what the MAP is for the LNAV approach? Is this related to the fact that RW30 waypoint is shown as a circled "fly-by waypoint" in the top down view?
Also, if the RW30 wayoint is the MAP for the LNAV approach, why is the 1.5NM location identified? What's it for?
As I typed this, it dawned on me that 1.5NM from the RWY is much too far to be a MAP, so perhaps I should have logically eliminated A based on that observation, but still want to understand more.
Thanks!
I’m a little confused by this question on the IFR written:
(Refer to figure 152). At what point would a pilot execute a missed approach for the Baro NAV and LNAV approaches at LBF?
A - 3100 feet DA for Baro NAV, or 1.5 NM from the RW30 waypoint for LNAV
B - 3280 feet DA for Baro NAV, or the BEMXI waypoint for LNAV
C - 3100 feet DA for Baro NAV, or RW30 waypoint for LNAV
I selected A, but the answer is C.
