Landing Light SOP

I can see them just fine with regular lights. The HIGH beams not only
force me to hit the night option on my rearview mirror (reducing the
chance to see cars without any lights in the mirror) but are incredibly
aggravating.

Enhancing visibility is a good idea. Blinding me is not.

that being said what is the SOP for airliners when it comes to turning
on the landing light. Is it altitude based, distance etc...

below 10000.

Are you talking about the high lights being a problem during the day, or at
night?

There is also a Quartz equivalent lamp #Q4509 with the same
specifications except a 100 hour life and 140,000 candlepower.


The Q4509 is what I used in the 182. With the standard bulb I'd be
lucky to get 25 hours, with the Q bulb I was getting 100+ hours.

There is nothing - absolutely nothing - half so much worth doing
as simply messing around with airplanes.

I hate those car lights!,
Oh they'd be great on my car while driving, but being in a car heading
into them I hate it! Blinds the crap out of me in my wife's low sitting
car.
Doesn't bother me as bad in my truck.

I know what you mean. IMHO, they ought to be banned, except for use on high
beam, with a regular light for low beam.

I don't know if there are any stats on crashes being caused by blindness
from oncoming cars with HID's, or if there ever has been a crashed cause by
HID blindness. There have been times when I felt unsafe, because of being
temporarily blinded by those things on two lane roads.

I will defer to more knowledgeable AMEs here for an "exact" definition if I
am using the term "certified" incorrectly .

What I meant was FAA approved replacement part as compared with similar
specification part lacking correct aviation paperwork. It is my
understanding that some owners install (but do not log) non-certified??
replacement bulbs due to much lower cost.

Happy landings,

I would think that owners who are not as fussy about
using certified bulbs are more likely to use the light for safety.

There is a current thread, subject "Landing Lights at NAPA", on
rec.aviation.owning that discusses this subject extensively.

Apples and oranges. On the ground, a landing light (or headlights)
will probably enhance visibility, even in the daytime. (Although, as
other posters have noted, not all the time.)

I see a lot of the newer cars with those damed bluish white lights.
They say they are better than the regular ones, but to older eyes
those things are blinding. One on dims is worse than a set of
halogens on bright for me.

I don't fly around with my landing light on (unless I forget) as it's
in the wheel well and does nothing except warm up the well a tad.

I wonder, though -- do landing lights in the daytime really do that
much for you? I seem to recall reading that bright lights coming at
you during daylight hours actually tends to camouflage what is behind
them.

(Groping back into the distant recesses of my history minor here...)
Didn't the British actually experiment with using extremely bright
lights to hide their aircraft during the day?

Do headlights hide an oncoming car? No.

But they make a VW look like it's twice as far away as a buic right
beside it.

The US did some work using a bank of lights facing forward to hide an
aircraft for ASW work. From what I've read it was effective, but was
never implemented.
