I'm adding the runways for EGHE (Scilly Isles/St Mary's) into Fly!2, yes, it's still out here

I need some help with decyphering the runway lighting comments on the chart though. I'm happy with 'END lights red' but can someone explain 'HI bi-d with omni-d component' and '2 HI edge lights'.

Thresholds are described as 'HI green W bars' and 'HI green'.

I don't know if the charts in the UK use the same shorthand symbology that we use here, but I suspect it's very similar if not the same.

HI = High Intensity (very bright)
bi-d = bi-directional (seen from either runway direction)
omni-d = omni-directional (seen from all directions)

We have a chart legend on the site somewhere (I know it comes on the FlightAdventures CD-ROM Crew disc 1), but I'm not sure if it includes runway lighting. I guess we'll have something else to add to disc 2!

Thanks Ben

I guess HI bi-d with omni-d component is brighter when viewed down the length of the runway than any other direction?

How about the threshold lighting. What would you expect to see for HI green W bars (this end also has PAPIs with an NDB approach available).

One runway is causing me problems as it's only asphalt for half it's length then turns into turf. If it's anything like the end of my garden path could be a tricky interface there

Yes, but keep in mind that other runway lighting, unless omni, can't be seen/are very hard to see from all directions.

There's usually a line of HI greens at the threshold with white lights in a staggered bar configuration leading up to the threshold. However, the configuration of the number of bars comprised of these white lights vary. You might try looking up SSALR, MALSR, and MALSF to see some standard configurations for approach lighting configurations.

PAPI (Precision Approach Path Indicator) are the four lights that indicate approach angle on the left side of the runway.
