General Navigation questions not from DB
Hey guys,
I'm doing my ATPL at the moment and I'm struggling to find the right explanation to the following questions: (if any of guys could help me I would really appreciate it)
Number 1:
A Northern Lamberts conformal conic chart is overprinted with a false grid.
The constant of the cone of the chart is 0,80.
At 60°W the grid track is 090° and the true track is 010°.
At which longitude is the false grid aligned?
a) 160° W b) 140°W c) 020° E d) 040°E
Number 2:
A Northern Lamberts conformal conic chart is overprinted with a false grid which is aligned with the 25°W longitude.
The constant of the cone of the chart is 0,80.
If the true track at 120°W is 090° will the grid track
be:
a) 014° b) 166° c) 185° d) 355°
Number 3:
A Lamberts conformal conic chart is overprinted with a false grid.
The constant of the cone is 0.60.
At 40°S 70°W the grid track is 197° and the true track
is 239°.
At which longitude is the false grid aligned?
a) 112° W b) 028°W c) 000° E/W d) 030°E
Number 4:
North polar stereographic chart is overprinted with a false grid.
At 77°N 37°W the grid track is 175° and the true track is 093°.
At which longitude is the false grid aligned?
a) 045° W b) 045°E c) 082° E d) 119°W
