This is a video detailing the ROUTEING CHARTS in details with explanation of all symbols and information available in it. Hope you will find this useful for your future career path
Sir, Routeing charts are not published every year. Whenever they are published, it will be shown well in advance in the charts to be published section, and will also be shown in the new charts published and available section in the NTM. The Chart catalogue will show you the current edition and, if you have internet access, the list of charts in force can be downloaded from Admiralty website for every week. Hope your query is well answered. Regards ❤️
Sir, Thank you for the words of encouragement. Now, ROUTEING charts are basically charts that have tons of historical data that they compiled to give us an idea of what weather factors are generally happening at that place during a certain month of the year. This is not a prediction. Its just a compilation of past events. Wx Charts are basically charts that are giving us a prediction for the next few hours or days with observation through satellites or weather stations. What we receive on a Wx Facsimile is a Wx Chart. Surface prognosis, analysis and all those types of charts. Hope I could clarify the terms. Wx - Weather.
It depends on the area sir. They are provided as an average for that area (lat / long) which helps in easier identification of wind occurance and speed at that point. Regards ❤️
@prasobhsugadhan Thanks for the response sir.. 🙂 I have one more query.. what is the difference between routeing charts and ocean passage of the world ?? Why do we need later one if we keep former ones on board.. one more question.. do we always keep small scale charts on board in case of emergency??
Sir, if there is any update, it will automatically come in the NTM. Also, a weekly chart list is provided in the admiralty website with present edition charts. Again, cumulative notice as well as the chart catalogue gives you the valid Routeing chart numbers. Regards ♥️
Sir, in general, it is provided as marks on Routing charts. But, to get a better update, you can take service from ice service provider, and also all weather synopsis and prognosis charts for surface weather will show the current limit of ice. The international ice patrol normally gives the limits of last seen ice and its rate and speed of travel. I hope you got a good understanding. Regards ❤️
