REIL consists of sequenced flashing white lights, one at each corner of the threshold

ODALS consist of omnidirectional flashing white lights, one at each corner of the threshold, and also a line of them extending out to 1500' from the threshold.

I haven't actually seen ODALS at any airports I've flown into, but I can tell you that they probably look like a string of flashing white lights  Big thumbs up

Old nickname: Running Rabbits, because of sequence of flashing from furthermost point away from the runway back to the runway threshold.

Not to start an argument or anything, Buff, but I always thought of the "Running Rabbit" as the RAIL lights, which are defined as Sequenced Flashing White Lights, these are the lights that are integrated into most of the approach light systems shown in the approach lighting layouts in my approach plate book, and those are the ones I assume I've seen at all the airports I go into.

ODALS are defined in my book as Omnidirectional , not Sequenced.

 Big thumbs up

Omni-directional Approach Lighting System is a series of omni-directional strobes with omni "rabbit" lights and omni REIL lights. The "rabbits" are defined at RAIL as seen in many common ALSF-1 and ALSF-2 approach lighting systems. The omni system follows an actual vertical arc down to the runway. You can see them for about 8 miles and I believe some airports down in Louisiana, Mississippi, or Arkansas may still have them. I have seen them in person before. Note below:

The charts show RAIL lights and ODALS lights as different. They look different I assume too. "Omni" means all directions, RAIL can't be seen very well from the side. REIL are masked so you can't see them from the side and aimed at an angle of approx. 10 degrees.  Big thumbs up

Jepp: ODALS - including sequenced flashing lights (rabbits);

Air Canada: "P" type/ODALS with sequenced flashing lights.

Omni-directional means that they can be seen from all directions as opposed to when you're lined up on them, much as runway edge lights are partially focussed.

I went down to the airport(CYKA) and checked. They indeed are the running rabbit kind. They look pretty cool close up, but the bright strobes strain your eyes. Are they a new development or old technology?


p.s. the ODALS lights replaced the old apprach lights about a month ago..............

"Running Rabbits" are an old (older than me) kind of approach lighting aid designed to attract one's eye from an initial approach point to a runway threshold. The formal term "ODALS" has incorporated this "older" technology.

How would you rate them in terms of visibility and performance?.....are they better than a row of non-flashing lights?

They are most useful to me, in locating the final approach segment from a good distance away. On final approach though, for the most part, I find them quite annoying. In the past, I'd ask for the sfl's to be turned off, but at the airport I asked, they were unable without turning out the rest of them (edge, thld, REILS) too!

Best Regards,

Buff
