HI 

 

Im a bit confuised about capturing the VORs on 777, i put 2 differance vor on the fmc then go to the vor 2 for examp, push to the LOC button and nothing happens. on 737 you enter 2 vors than aproach the vor on the site of the master FD with a accepteble angle then it etabilishes with no problem, but on 777 its a bit tricky as we dont have the master selections on FD.(it doesnt etabilish  when  both sides are the same vor neihder).i dont even see an ''arm'' on the pfd and loc button doesnt illuminate.

 

thanks

 

Yeah, 777 does not capture a VOR with loc.

LNAV is normally used to track VOR radials in this modern aircraft.

 

You can still follow a VOR radial manually with Track Select while looking at the cource deviation indicator on the ND VOR mode.

 

But normally you would program the route in the CDU legs page or select the VOR approach from the database and fly it with LNAV. (you can ARM Lnav just like you did with LOC by the way and it will intercept the route/final approach)

Thanks for the answer.

 

How about the flight director in the 777, is there any equivalant to the 737ngs master side or airbuses sidestick prioriy To see who is the pic etc ?

Eeeh not really.

 

Except that depending on whether you engage the AP via the push switch on the capt or copilots side of the MCP you should see an L or an R on the PFD.

In case of L the capt side is providing input for the AP FD system. changing the capt altimeter setting will in that case change altitude, wheras changing the FO altimeter does nothing then (and vice versa when R is indicated).

 

The 777 internal systems cross check each other automatically and display exactly the same on the left and right side. There is no pilot cross checking possible unless you start messing with those 3 switches on the far left and right side next to the PFD (which you normally would not do)

 

Thank you for for the information

In aircraft like the 777 with an advanced RNP system, you are even allowed to use LNAV to track VORs and NDBs on final approach even if you aren't receiving the signals from the navigation aid! This is why a lot of 777s are rolling out of the factory with ADFs installed - they don't need them!

You can actually use TRK SEL to track them too - it'll accommodate for wind drift.
