There are also no approach lights installed yet.
Most of approach lights poles are installed on both directions of the runway. I doubt if they are already operational.
Prominence of the new runway was reported by EPKT-based pilots several times. Local policy has been introduced a few months ago to turn on approach lights for any approach, even in bright sunlight.
Luckily Saturday evening there were no workers or machinery on the RWY.
They were. Some machinery is usually left on site during off hours. And even at night there are small technical tasks performed (cutting, sealing, measuring, watering, checking, whatever).
As far as I know this was VOR approach (with 11° offset), not visual.
Another contributing factor: both runway thresholds are almost exactly in line with tower, so it is very hard to visually distinguish if an aircraft aims for the right (well, left actually) one. Approach radar resolution is also not enough.
Finally, hint for crews flying to EPKT: ILS 27 GP is out of service, however LLZ is not turned off. Use if in doubt.
