I did a search on this subject, but didn't come up with anything, even though I'm sure it's been discussed.

Has anybody found in writing what is 'equivalent' to a 2D cell flashlight? Not what you've heard or what you think, but something in writing that a person could show the FAA and and say "my flashlight is compliant".

Thanks.
 
Our POI has decided that we can't carry anything except a 2 D-cell flashlight since he can't seem to figure out what is equivalent either.

Good luck.

Hmm, maybe a quick peek at the business end of a Surefire 6P would help him figure it out. It puts out 80 lumens, more than twice what's claimed for a 2 D cell Maglite. That information is readily available-sounds like a fed that just likes being a tool.
 
I haven't seen it in writing but during OE in the bus, the captain told me it had to be powerful enough to illuminate the wing tips. I don't know if their theory is to see the longest distance from any vantage point, but it wouldn't make since if you are flying an MD-80 cuz I don't think you can see the wing tips from the flightdeck.
 
I believe the 2D requirement is not for illumination power, but for lasting power. The D cells provide enough juice to last 30 minutes in the event of an electrical out at night. Not sure how long "equivalents" stay powered.

The Surefire is good for 11 hours at full rated brightness. Definitely enough juice to weld Barney Fed's eyes permanently closed.
 
Just tell your fed that you have it on good authority (me, FI.com) that 2-D equivelancy is based solely on weight. Hence, I have my flashlight stuffed with bologna. There's a damned flashlight on the flightdeck if I need one in an emergency, but there's no emergency food, for Pete's sake. A man's got to have his priorities.
 
Just ask your friendly Fed which light he'd rather have stuck in his face. A dull maglite or the built-to-blind SureFires and the like.

The problem is getting ramped by somebody other than our POI. That's why I was looking for some kind of written comparison. And I'm pretty sure that it has to do with how long the batteries last and not how bright.

I want to carry a Surefire, but won't replace my maglite until I can find something.

Don't get the A2 aviator. The LED is not bright enough and because of the LEDs in the reflector the xenon is not bright enough. Check out the Z2 LED.
 
Okay, if anybody is interested, I did some research and this is what I came up with.

From Maglite's website, a 2D cell flashlight puts out up to 16,200 candlepower, up to 36.5 lumens, and a continuous run-time of 9-10 hours.

A Surefire Z2 puts out 80 lumens and has a run-time of 11 hours. That sounds equivalent to me.
 
Just out of curiosity, do the planes you fly not have flashlights provided within them (i.e. attached in some way to the plane at each pilot's station)? I guess some do and some don't... anyway, the "2 D-cell equivalent" only seems to apply to "flying equipment required" in Part 91, (FAR 91.503(a)(1)) and thus to the flashlights provided for you within the plane. Part 121 only references a "flashlight in good working order" and does not specify a cell size (121.549(b)). So unless your ops specs require D-cells or equivalent, I don't know why you would carry one.

I carry a Surefire A2 and it's brighter than hell, and no FAA guy or girl has ever given me a problem about it when I have been ramped. Only occasionally have they ever even wanted to see that I had a flashlight in my flight bag. I don't think any of them has ever asked me to turn it on.

I think they got rid of the D-Cell requirement in 121, since we have permanent flashlights in the airplane.

We have to carry our own to make sure we don't use the installed units for walk-arounds, etc.

Where I work, using the aircraft flashlights for walk around inspections is verboten; we must carry and use our own. The idea, I'm told, is to keep the aircraft flashlights fully charged at all times. Also, I just went through recurrent brainwashing class, and it was explained that the D-cell requirement is not applicable, because it is not listed in our OpSpecs.

We no longer have the D-cell requirement either...we just have to carry two working flashlights.
