    Being a officer on board sir this will help me a lot currently completing my pre sea in anglo... Thanks for videos like this sir. ❤
    One correction in video the formula to find B is tan (dec) /sin(P).

  • @daniqueseamoore
    @daniqueseamoore ปีที่แล้ว +4

    qUESTION: For the time, wouldn't it be 1329 because it is daytime instead of (0129 the sun is not out that time) and as such the corresponding GHA would be 11 degree 27.3minutes??????

    • @sailorguide
      @sailorguide  ปีที่แล้ว

      Fir calculation we always take UTC time not the local time . So the time mention in GPS will be taken for calculation as mentioned in the video

    • @daniqueseamoore
      @daniqueseamoore ปีที่แล้ว

      Okay thanks for the clarity. So basically the LMT at that time was 1042... Hence why the true bearing of the sun was SE ?

    Question, the "P" value, do you also apply the LhA rule on a Star observation, where 360-LHA if the LHa is more than 180? Also can you explain more about the correct naming of magnetic error, for example when they are same name as the Variation, when you are trying to get the Deviation?thank you

    • @sailorguide
      @sailorguide  ปีที่แล้ว

      Yes LHA rule will be applicable to there also . Nd naming of the Deviation is very simple i showed in video also . Please do check out that one again because explaining it here will be a bit difficult

    • @sailorguide
      @sailorguide  ปีที่แล้ว +3

      Compass error is important for navigation point of view ... If we have a compass error of more than 5 degrees we need to request for the service for magnetic compass. Service engineer actually changes the magnetic bars inside the magnetic compass to adjust the error

    • @sailorguide
      @sailorguide  ปีที่แล้ว +1

      @@mdganesh5764 because Gyro error is independent of the magnetic field of the earth.. magnetic compass variation and deviation is the factors for Error , whereas Variation and Deviation we always mention in East or west.

    What would happen if the value of A becomes negative. If it comes negative are we able to remove the negative sign by just naming oppositely or do we need to just ignore the negative sign?

  • @grslink79
    @grslink79 ปีที่แล้ว +1

    sorry just something to clarify if u can pls.. shouldn't u have picked report (i) on the variation and adjust for year? I am under the impression that the -5 and -6 are not necessarily for the year you are on. could you double check ? thank u

    • @sailorguide
      @sailorguide  ปีที่แล้ว

      You are right in this video i have not taken yearly change of variation in the consideration..

    • @sailorguide
      @sailorguide  ปีที่แล้ว +1

      It will be minus because in Nautical Almanac Value of Declination reducing every hour .... So we will minus the d correction

    Sir, what's the point of determining the Gyro Error? I mean, you are not using it in any calculation?

    • @sailorguide
      @sailorguide  7 หลายเดือนก่อน

      Its to determine that our gyro is working properly.... Sometimes it can go offset

  • @shreyashmuley6462
    @shreyashmuley6462 11 หลายเดือนก่อน

    What after you log in the log book. Do we need to verify that deviation is acceptable or within limits or satisfy with some rules and regulations. What an auditor is checking in this log during inspection.

    • @sailorguide
      @sailorguide  11 หลายเดือนก่อน

      It should be in a range of your deviation card. If you have more than 5 degree of difference you need to get a service for magnetic compass
