Abeam....though it's said over the frequency quite a bit.

"The port goes down the throat" is how I was taught to find the throat and peak halyards on a gaff-rigged vessel. The throat halyard is attached to the end of the gaff by the mast, and is hauled on the port side.

On British war ships I believe directions are given with a colour. "Green five ooh" "Red twenty". iirc this is because you may order a turn to left but end up facing right (if that makes sense).

Is this because left, right, port, starboard are different due to your perspective? My right being your left etc.

Uxb99

Exactly what you said although it took me a while to get out of the habit of saying “clear on 4 and 3…..” :O
As someone mentioned upthread there is the possibility of confusion arising when communicating with the cabin crew so probably best to clarify eg captain’s side, FO’s side.

Left and right are relative to which way your body is facing inside the craft, but port and starboard are not. Which is the point of using them... they're absolute. Port is always the side that the doors are, the captain sits, and the wing with the red light bulb is. Starboard is always the other.

Apologies for nautical content. ;)

Only in IALA region B, the Americas, South Korea, Japan, the Phillipines, Taiwan...
In the rest of the world, the red marks are to port (left) as you return to port.

In Cincinnati I would imagine "returning to port" means "headed for Pittsburgh"?

Every day a school day, nonsense! I will say that a ride up Pittsburgh's Mt. Washington on the funicular leads to an Italian restaurant (name forgotten) which served the best martini I have ever had. The veal Marsala was excellent as well. Though Pittsburgh is a fine town, I'd prefer to make port in, say, Barbados.

Not on the archaic 737, still 1 and 2.

Boat hull language of ‘port’ and ‘starboard’ fix where the the pointy end must be. You can sit in a boat facing backwards and your left hand or pocket is still your left hand/pocket, but the unchanging starboard side of the hull will now be on your right.

It’s a bit like the ‘left’ bank of a river, which has directionality built into the concept and assumes that the river flows down and away from one. In this case it’s dedicated river language, there for a purpose. The Dnipro flows south, so Kherson is on the west bank, whereas Ukraine’s troops are now crossing to the east or ‘left’ side. (Even though it looks like the right side when seen on a north-facing map.) The old brain spins like a compass in oil.

Drifting sharply off topic, I've never been to Pittsburgh; I've been to Barbados (in 1971), but I chose to visit Cincinnati again for five weeks last fall (September) to escape the last of the Australian winter. After 17 years since I was last there quite a lot has changed. It's a terrible pity the inclines at Price Hill or Mt Adams are long gone.

Vaguely back on topic, in the car industry (or the minor backwater of it that I worked for, GM-H), while we didn't use port and starboard, we used left and right defined the same way - while facing forward - and all parts which had left and right side versions had sequential odd and even part numbers. Thus the left side part had an odd part number, while the right side part was numbered one higher to achieve a matching even part number. A supplier I later worked for used the same system.

washoutt 8th Dec 2022 08:45

On the other hand, street numbering starts with nr 1 on the right side, and nr 2 on the left side and all odd numbers on the the right hand side. Of course, looking from the start of the street to the end...

Not in our avenue. Odds on the left. Maybe streets are different.
Maybe it's down to which side you drive.

Not all of that is correct if you fly a helicopter!

Dunno, in one of the two cities i live the street numbering starts on one side, runs all the way through 1,2,3 through the end of that side and then returns on the other side. Which is why the highest street number and the lowest are opposite to each other. In the other i have the funny situation that the entry to the underground garage is 30 numbers lower than the pedestrian entry to the building, all of 15 meters apart...

Apart from that, the starboard/port thing seems to be predominantly an english discussion, haven't had that anywhere else in aviation.

What are those fuel valves for? The big red and green ones are the ones I remember. Havn't been in an Islander since about 1987.
Also, why are the mags on and the fuel pumps off?

No sailor would ever misuse the word "abaft" to means moving in a sternwards didection. Never ever. 'Abaft' can only describe a relative position. "The helm is abaft the mainmast". The destroyer turned abaft the cruiser".
It cannot possibly be used as a direction of motion. That is described as 'astern'. A vessel - or a helo - can move astern, it can never move abaft unless it moves abaft relative to something else as the term expresses where it moved, not in what manner or direction.

Port is always the side that the doors are
Bit of a problem when all our airliners have doors on both sides, albeit the port one is usually used for entrance, you could have your DC-3 with the door on either side.

Was the MRCA (Panavia Tornado) remotely British? If so, I claim to have been subject (as in participated in development). Doesn't change what I posted though.

Maybe you only need fuel pumps on initially, given it's high wing I would imagine gravity does most of the work. That's just a guess, I have no experience of twins, let alone one of these.

He probably was, as per the rest. But seeing that it was almost forty years ago, I’m not going to be losing much sleep over it. ;)

Does that include to change the navlights from left to right and vice versa?

Inverted, does "bank left" mean roll left, or point the lift vector to the left? :8

which is where the stage left / stage right used in the theatre comes from - an actor stood in the middle of the stage facing the audience , up stage and down stage is due to raked stages wheerhe the 'back' Upstage is higher that the front 'downstage' to give the audience a better view of the action

I'm virtually certain that your colleague will actually have said "GOING ASTERN". "Abaft" has a completely different usage and meaning , such as "abaft the beam", meaning a relative bearing further aft more than 90 degrees.

From either the canopy configuration, inbuilt steps or appropriate GSE; Hawk, Tucano, Phantom, Tornado, Javelin etc; port side.

Koan 10th Dec 2022 12:20

The gauges on the Islander do look like something off a boat

Discorde 10th Dec 2022 12:29

There is a potential 'gotcha' with left/right identification on engines, as in:

'Looks like we'll have to shut it down.'
'Agreed. Make sure we get the right engine.'

Referring to '1' and '2' (on a twin, as used to be the case) would remove the problem.

That's actually an interesting question. Since the early B-36s didn't have the jets, I'm guessing the prop engines were 1-6, and when the jets got added they were 7-8 on the left and 9-10 on the right.
But that's just an educated guess - does anyone know for sure?
