Depends on the aircraft. Some, like the 757, have the nose gear so
far behind the flight deck that the crew must adapt. They allow the
nose to travel well beyond the centerline when turning. On small
aircraft, the nose is simply kept on the line.

Centerlines are simply an aid to keep you to the center of the
pavement, helping to ensure clearance to the sides. In some
circumstances, such as taxiing between rows of parked aircraft, a
centerline makes maintaining equal clearance to the sides much easier
than trying to judge inconsistent edges. Each pilot must learn where
the centerline falls in the field of vision on a particular aircraft.
Some tail draggers need to swerve back and forth, as the pilot has
poor forward vision with the tail on the ground.

When snowbanks are present, all bets are off.

Are they just a night aid?

Not at all.

I'll be! I didn't recall that ever becoming a problem.

You know, a humorous thought just occurred to me.

A small camera and wireless transmitter, along with a wireless receiver and
LCD screen to match, is now available as a back-up aid for people not
comfortable backing up large cars and vans. All this for less than $100!

Something like that would make a lot of sense for a big airliner, wouldn't
it? g

I suppose a pilot could get one of those and a little duct tape, and fasten
it on the nose gear leg before he took off, HuH? G

To finally answer your question, They are used all the time (Day and
night). During SMGS operations (below 1200 RVR), some are marked with
with a "Judgemental oversteer" for the larger airplanes.

Excellent! Finally a useful answer. Thanks!

There are pilots here who fly large aircraft, and who therefore know the
correct procedures for taxiing, but they may be too annoyed to respond since
they would be instructing Mxsmanic as well. IMHO, they are correct, since
everyone who has reason to move large aircraft has access to specific
instruction.

Peter, this is a very insightful post you have made. You are wise
beyond your experience level. You are the only one so far who has made
reference to what we call the load bearing surface of taxiways. The
main reason for overstearing is to keep the MLG on this load bearing
surface.At smaller airports, it also keeps the engines over the
taxiway where there is less FOD, snowbanks, etc..
I have to respectfully disagree with you on the MX issue. He is only
one poster, and is easily ignored. The problem is all the other self
appointed aviation experts on this list that chase most experienced
people off. A good case in point is a thread I saw a few months ago
about an airline crew experiencing a near midair. This story was
obviously fabricated (The OP later admited it was), and yet the people
who pointed this out were flamed by the self appointed experts, some
even AFTER the OP admited the story was embelished. Another good
example is the threads dealing with aerodynamics. Here is where alot
of the EXPERTS beleager stuff well beyond the point of anything having
to do with the actual flying of an aircraft. When someone DOES post a
correct answer, the experts often ignore it and just keep on arguing.
For kicks I have looked at the "View Profile" function and this makes
it easy to see if a guy has ever had anything useful to add.Sadly, it
is these types who make people decide that they have better things to
do with their time.
Hope you get back to it soon.

I am often interested in the answers to the questions of Mxsmaniac but the
elitists here would rather deride. There are probably other non-fliers
lurking who are too scared to ask for fear of getting the Mxsmaniac
treatment. Yes, I know he has offended some.

The main problem is that some self-centered jerks feel that it's
necessary to deride every one of his questions, even _before_ there
are any responses from others, or from him to others.

The people who do that, are not what I'd consider "real pilots" any
more than I consider the people on technical forums who act like know-
it-alls, as real gurus.

Then, of course, you have the rednecks and real trolls who'll bash him
no matter what, because they see him as an easy target. Coward is
another word for those types.

It depends on what you are taxing.

If I am flying a Champ or a Cub from the back seat, I will do S-turns,
wandering back and forth across the taxiway centerline to see what is
out in front of me.

If I am flying a tricycle gear airplane and the centerline follows an
uneven seam in the pavement, I will taxi to one side or the other of the
line to spare my nosegear. If the pavement is smooth, I follow the
centerline.

I know some pilots who wouldn't let that small detail stop them. G
