monique.hubrechtsgm Posted December 26, 2018 Share Posted December 26, 2018 You can fly now non stop to down under in 18 hours. An airplane is programmed in nautical miles like a ship. Why is that. And who invented it. Link to comment Share on other sites More sharing options...
maggyd Posted December 26, 2018 Share Posted December 26, 2018 Happy Christmas and a Happy New Year to friends old and new , I think this has been our last year in the Motorhome sadly :-( but I will still pop on to see how everyone is doing xx Link to comment Share on other sites More sharing options...

An airplane is programmed in nautical miles like a ship. Why is that. And who invented it. The diameter of the world is divided into degrees, one degree = 1 nautical mile = one minute If I'm correct ? Link to comment Share on other sites More sharing options...
Geeco Posted December 26, 2018 Share Posted December 26, 2018 Monique, Qantas has commenced a non stop flight from Perth to LHR. Yes it is around 18 hours however if you live on the east coast like most of the population there is still a 4 or so hour flight to Melbourne, Brisbane or Sydney. Qantas are also looking at the viability of New York from the east coast and Paris. No way I would spend that long in a plane without a break.

An airplane is programmed in nautical miles like a ship. Why is that. And who invented it. The diameter of the world is divided into degrees, one degree = 1 nautical mile = one minute If I'm correct ? Nearly Will but not quite. A minute is 1/60th of a degree and 1 minute = 1 nautical mile = 6080 feet or 10 cables. A Cable = approx 100 fathoms (Which was the standard length of a sailing ship anchor cable) A knot is by definition the speed of 1 nautical mile per hour. (Called a knot because in headline terms a seaman threw out a rope from the back of a ship with a piece of wood and a weight attached which sat dead in the water, then counted the number of knots tied into the rope for a period of 30 seconds (timed by another seaman with a 30 second hour glass) The knots were spaced at known intervals along the rope (47'3") - so the navigator could work out the speed of the vessel in "knots") Aeroplanes have always (*) used the same Navigational standards so their speed is usually stated in knots. (*The USA used to use mph, but changed to knots in the late 60's) Link to comment Share on other sites More sharing options...

Alanb Posted December 28, 2018 Share Posted December 28, 2018 laimeduck - 2018-12-26 11:40 PM ..................................................................................... Nearly Will but not quite. A minute is 1/60th of a degree and 1 minute = 1 nautical mile = 6080 feet or 10 cables........................................................... Now I am puzzled. Does this relate to degrees of longitude at the equator, or lattitude? Distance of degrees lattitude will increase at the poles , due to the Earth being flattened there,(oblate spheroid). So most probably degrees longitude at the equator. Can someone please confirm which? Alan Link to comment Share on other sites More sharing options...

Alan Alan, you are correct to say that distance at different latitudes will vary slightly since the earth is not a perfect sphere. It is now internationally accepted that the distance (1852mtrs) is taken at 45 degree latitude. There is also a nautical mile (UK) of 1853mtrs just to add to the confusion.

laimeduck Posted December 29, 2018 Share Posted December 29, 2018 I think Monique was commenting on Colin's comment that he was late in wishing happy Christmas. It won't be long with rocket flight before someone downunder can celebrate Christmas there, then do the same on arrival here? A bit obtuse - but Happy Christmas to you anyway!

monique.hubrechtsgm Posted December 29, 2018 Share Posted December 29, 2018 Impressive comments Will forward another one about old sailing time, that the original lies somewhere in the uk. But i cant find it in my desk. It is from a place to place. Still taking the above into account. Link to comment Share on other sites More sharing options...
