NV - What is the convergency calculation on a lamber chart?
Convergency = Change of longitude x sine parallels of origin
NV - On a lambert chart outside the standard parallels the scale….
The scale expands outside the standard parallels
NV - On a Lambert chart with in the standard parallels the scale…
The scales contract
NV - On a lambert chart great circles away from the parallel of origin are curved towards?
Great circles are curved towards the parallel or origin
NV - On a lambert chart Rhumb Lines are curved towards?
Rhumb lines one Lambert chart are curved towards the nearest pole.
NV - On a lambert conformal chart, great circles are straight lines when?
Great Circles are straight lines around the parallel of origin or if a line crosses the parallel at right angles.
NV - Normally where is the projected chart most accurate?
The chart is most accurate where it touches the projection or along the tangential to the reduced earth.
NV - QUJ refers to what Q code?
QUJ - The true bearing to.
NV - QDR means in the old Q code system?
QDR is “The magnetic bearing from”
NV - QDE mean in the old Q system?
QDM means “Magnetic Bearing to”
NV - QTE is a Q code for?
QTE is referring to “True bearing from”
NV - The Track Error Angle is the Angle Between?
Desired track and Actual Track
NV - If Track > Heading where will the drift be?
Starboard or Right hand drift
NV - If Track < Heading where will the drift be?
The drift will be to the Port or left
