understanding bearing ?

[flag4]

hi hunters,

im trying to understand bearing - in light of doing manual targetting.

im using olc gui mod and learning from the vid tutorial.

but im confused - still ! - with understanding bearing.

here goes: if my WO reports a ship at bearing 301 who's bearing is this, is it my bearing - from me to him or his bearing from him to me. if it is his does this make his bearing 59 degrees ( ????) to me - im lost, but feel if i can clarify this i can move on to use the plotting tools etc.

how does BEARING work, how come there are two, as above. if you watch olc's tutorial you see him drawing up a 59 degree bearing after his WO has reported a ship at 301 degrees.

i know i have posted this question before once and twice over, but i cant get my head round it, maybe a diagram would explain it better - i dont know.

i dont even know if i have made myself clear ??

i do find it a bit , but im not angry just confused.

i feel its all well and good being able to DO something but the secret to me is knowing WHY something is. at the moment im not that close to either.

im grateful for any attempts at clarifying this for me

If a ship is reported bearing 301, it is from you to the target ship. Bearing 000 is straight ahead, so 301 degrees would make the target ship at your left, about 10 o'clock position.

[sharkbit]

301 is the relative bearing. In other words, relative to your sub, with 000 being on your bow, no matter which direction you are heading, and, as Captain said above, 301 being 59 degrees to your left.

True bearing would be the actual compass course that you would have to steer to put your bow directly on the target.
Example: If you were on course 270 and the ship was reported bearing 301, you would need to come to course 211(270-59=211) to put the target directly in front of you.

Hope that made sense.

bearing is super easy.

i suppose you are familiar with the "clock system" with aircraft.

for example: 12:00 is straight ahead, 6:00 is behind you, 3:00 is to the right, and 9:00 is to the left.

think of the "bearing" as being the "clock system" of boats, ships and submarines

consider this: while the compass is your "heading" and changes as you move in relation to the earth, "bearing" wont move, and is the relationship of all other objects to in relation to you.

000 = straight ahead or "on your nose" or "on your bow", 045 = 45 degrees right of your nose/bow, 090 = 90 degrees right of your nose/bow, 180 degrees = on your tail/stern etc etc.

"Ship spotted, bearing 135 degrees, long range" this ship is 135 degrees right of the bow, all you have to do is whip out the binoculars and point them at a "135" bearing and you should see a ship in the distance.

the only time your heading and your bearing will match is when you are heading exactly north.

to clear up more confusion (or create more ) every ship has its own bearing.

you dont care what the target ships watch officer would tell their captain about where to look for you. what is important is what your bearing to the target is. ie... if you see him on a 301 bearing, thats the bearing that gets put into the TDC.

[Sailor Steve]

Bearing is always relative to your ship. No matter what direction you are pointing (heading), your bow is always zero. The SH3 map tools should have a bearing compass tool that moves with your sub and turns with it. Also, if you look through the periscope the moving numbers at the top show the bearing.

[CptGrayWolf]

C'mon! You guys all repeated what I told him, except I was shorter and clearer! :p

[Sailor Steve]

Yeah, but...well...y'know...but...

when offering an explination on what could be considered a confusing or complicated subject you have to offer several examples. this keeps the reader/student/confused individual from thinking the rules apply only in the situation you have offered up for explanation.

the individual may come back and ask "Is the ship only straight ahead and to the left when im going north then?"

its not that you did a bad job, but every one of these "how does this work" posts on subsim has about 25 additional posts of different ways of thinking about the situation even though each post makes the same conclusion.

its true, everyone likes to put their two cents in.

but one thing i have learned through so many years of teaching others to fly airplanes is that its also true that one way of explaining something to someone gets no results, while another way of explaining it causes them to understand perfectly... even though all you did was re-word exactly what you just told them the first time...

anyone with teaching experience of any kind knows exactly what i mean. :rotfl:

PS i know you were mostly joking... so am i mostly

[Bosje]

he sees you at his own personal bearing, which is what his watchofficer would tell him: uboat spotted at bla bla degrees. that is the value which is called Angle on Bow. also important


oh and don't eat yellow snow

yup i just say

"My aircraft"

Flight instructing was probably the most fun job i have ever had. too bad the pay is rotten or i would still be doing it!

Being an instructor offers the best of so many aspects of aviation. you get to share the science, beauty and adventure of flying with a person who is enjoying all of these things aviation has to offer for the first time. seeing their reaction to the new world of flying is part of the greatness of the job. As a flight instructor you really share in the student pilot's sense of accomplishment every time that little light bulb turns on over their head.

The job offers a huge sense of satisfaction every time you turn out a new pilot, because lets face it, teaching is challenging... especially if it is a complicated task. and the student and the instructor both have a set of challenges ahead of them which they must finley tune into one another and meet those challenges as a team.

new student introductory lessons were always fun too, you just schedule it on a saturday morning, take off and hand it over to them, fly to a nearby pancake breakfast, enjoy a few flap jacks and the friendship of the pilot group and head back home and ask them if they are interested in learning to fly. 20 percent of the time the answer is "yes" 78% of the time the answer is "HELL YES!!!"

Lucky man... I always wanted to be a fighter pilot but my math was too weak. I don't want to steer this topic off course, but quick question, what do you fly?

[flag4]

thanks all very much for responding.

i understand whats being explained, but

something is not quite right - ive missed something or not expalined what i dont understand myself.

god dam it ! something is eluding me ! i just seem to go blind when confronted with numbers that have to work together to make something happen......

" i have his attention but not his mind..." :school report, maths, 1976.

and also i think GoldenRivet hit the nail on the head about 'expalining one thing in many different ways' it can get lost to the listener/pupil: everyone hears things differently.

i will be reading through your posts hoping to clarify what i need to understand.

i'll go back to OLC's tutorial and see if it all fits.

thanks again
