I know that in the late 1990s, Delta replaced the emergency floor-mounted pathway lighting with seat-mounted lights on most of their aircraft. The exceptions were the L-1011s, 727s, and MD-90s, which retained their floor-mounted lights.

I haven't flown on a Delta MD-90 recently, however, does anyone know if they still have the floor-mounted emergency lights, or have they been replaced by seat-mounted lights? I presume with some of the mods the MD-90s got that the floor-mounted emergency lighting may have been replaced by seat-mounted lights.

All the MD-90s now have floor mounted glow-in-the-dark photoluminescent strips on both sides of the aisle. The system gets recharged by the flourescent cabin lighting...it is 100% non-electric. There are still lighted (electric) sign and overhead lighting in the cabin ceiling.

Here is a little light reading for you:

This plane is built to withstand anything... except a bad pilot.

That's interesting, considering that the ex-TWA 757s were delivered with the photoluminescent strips, but DL then replaced them with the seat-mounted lights.

If the 739ERs have photoluminescent strips, DL will need to update their safety video to take that difference into account.

I love what you did there.

No they won't; the videos are not required to be that detailed. The verbiage that the Fed requires is very general, and goes something like, "In the event of a power loss, aisle path lighting will illuminate. A change of direction or color indicates you have reached an exit."



As a mechanic, we love the photo-luminescent strips; the electroluminescent ones generally last about ten minutes into the planes first day of service, and then some section needs to be replaced every time you blink an eye. Hate those things. And seat mounted bulbs are just THAT MANY more bulbs to keep track of, except that (at least at the carriers I've worked for) escape path lighting is a non-deferrable item, so you end up with more gate delays while changing a bulb and then doing the requisite 100 pages of paperwork.

The TWA light strips were used by them fleetwide, DC-9 to 747.

One problem that we have is when a shipset of carpet gets changed out, someone inevitably uses a carpet knife to trim the edges and wiring under the carpet gets cut. Unfortunately, the person who changes the carpet does not have to fix the wiring.

An even better reason to just switch to photo-luminescent. NO WIRING!
