Is completely messed up when selecting LNAV+VNAV...

 

Does anyone else have this? The DP calls for a left turn heading 240 to intercept the 196 radial off EHF... the NGX wants to make a loop d doop right turn the long way around to the west. My navdata is about one cycle out of date now...

AIRAC navdata says that you have to climb to 1007' before turning 240*. But the aircraft cannot climb so rapidly to get to 1007 to turn 240 and intercept 196 to fix MARIC (or 196 from EHF). That's why it want to make a right 300* turn.

 

I've checked the charts and there's no 1007 restriction http://155.178.201.1.../00036MARIC.PDF .

So looks like nav data is not correct.

 

Not sure how it would be flown in RW, but I would climb to 400AGL, manually turn to 240, intercept 139 and engage LNAV. If needed do a direct to MARIC.

I think RSVIT's suggestions are good. If you have a screenie of the LEGS page, it would help.

 

Sometimes RW DPs don't work and you have to either monkey with the LEGS or just <gasp> not follow the magenta line for a bit.

 

In this case, I would just have MARIC as the first fix with the 196 crs inbound. After the 240 turn and wings level, select LNAV.

Thanks.... I did just fly with heading... I don't mind flying without LNAV.. When the plane doesn't go where I want or expect I'm taking over hehe...
