  • Gyros, grid navigation, Polar steoreographics in Ops

    Can anyone from BGS confirm if these still form part of the syllabus ? Could not find strong evidence of them in the LO's
    What should we do?

    The current syllabus includes:

    071 01 03 02 Transoceanic and polar flight
    (13) Polar navigation
    Terrestrial magnetism characteristics in polar zones
    State why magnetic compasses become unreliable or useless in polar zones.
    State in which area VORs are referenced to the true north.

    Specific problems of polar navigation
    Describe the general problems of polar navigation.
    Describe what precautions can be taken when operating in the area of compass unreliability as a contingency against INS failure.
    Describe how grid navigation can be used in conjunction with a Directional Gyro (DG) in polar areas.
    Use polar stereographic chart and grid coordinates to solve polar navigation problems.
    Use polar stereographic chart and grid coordinates to calculate navigation data.
    Use INS information to solve polar navigation problems.
    Define, calculate: transport precession, Earth-rate (astronomic) precession, convergence factor.
    Describe the effect of using a free gyro to follow a given course.
    Describe the effect of using a gyro compass with hourly rate corrector unit to follow a given course.
    Convert grid navigation data into true navigation data, into magnetic navigation data, and into compass navigation data.
    Justify the selection of a different north reference at a given position.
    Calculate the effects of gyro drift due to the Earth s rotation (15 degrees / h x sin Lm).


    The NEW syllabus (2020???) gets rid of just about all of this! SO, by the letter of the law, all the GRID stuff is still in the syllabus, BUT, as far as I know, we have not had questions on any of this for quite some time ..... seemingly we are creeping into the new syllabus already.

    Last thought; they have been adding a large number of new questions over the last year or so, so I'm pretty sure all of those will be compliant with the NEW syllabus. So, I don t think you are going to see any GRID or polar stereographic questions in OPS!!
