What colors are wingtip navigation lights?

[oboe]

Are they Red (Port) and Green (Starboard) or Red (Port) and Blue (Starboard)?

I though nav lights were Red/Green, but my pics of the restoration of White 33 P-38 show a blue lense on the Starboard light.   Is this a change for modern day aviation, or have they always been blue all along?

the red ship left port

It's actually green/blue like the lights at intersections are. The red lamp is not strictly red, either.

[Devil 505]

When illuminated the light will appear green, but the lens/bulb may look closer to blue when off.

Here's an F-14 for example.

Why are the sides are called port and starboard.

[GScholz]

For the same reason it's called an airliner and aeronautics.

[DubiousKB]

Why are the sides are called port and starboard.

I sorta wondered this myself.... Is it because when you walked "the plank" it was the side facing the stars, away from the port?    Would be interested in the history of these word origins...

Port and starboard are nautical terms for left and right, respectively. Port is the left-hand side of or direction from a vessel, facing forward. Starboard is the right-hand side, facing forward. Since port and starboard never change, they are unambiguous references that are not relative to the observer.

The term starboard derives from the Old English steorbord, meaning the side on which the ship is steered. Before ships had rudders on their centrelines, they were steered with a steering oar at the stern of the ship and, because more people are right-handed, on the right-hand side of it. The term is cognate with the Old Norse stżri (rudder) and borš (side of a ship). Since the steering oar was on the right side of the boat, it would tie up at wharf on the other side. Hence the left side was called port.

Formerly larboard was used instead of port. This is from Middle-English ladebord and the term lade is related to the modern load. Larboard sounds similar to starboard and in 1844 the Royal Navy ordered that port be used instead. The United States Navy followed suit in 1846. Larboard continued to be used well into the 1850s by whalers. In Old English the word was bęcbord, of which cognates are used in other European languages, for example as the German backbord and the French term bābord (derived in turn from Middle Dutch).

At night, the port side of a vessel or aircraft is indicated with a red navigation light and the opposite side with a green one, to help avoid collisions. The International Regulations for Preventing Collisions at Sea state that a ship on the left must give way to a ship on its right. If the courses of two boats are intersecting, the helmsman usually gives way to a red light by going around the stern of the stand-on vessel. Sidelights are each lit from right ahead to 22.5 degrees abaft the beam on its corresponding side. A mnemonic for this is "If to starboard red appear, 'tis your duty to keep clear. Green to green, red to red perfect safety, go ahead."

Was a rhetorical question.

Also the steering oar could be damaged by the dock.

I always thought it was because both port and left have 4 letters.......

A rhetorical question is a figure of speech in the form of a question that is asked to make a point rather than to elicit an answer. What was the point you were trying to make?

And right has 5 letters like green.

It's amazing how many people don't know or deliberately don't follow the standard rules of water navigation at night on lakes.  Specifically the "give way to a visible red light" part.

Not many know what headway speed or no wake mean either.
