^That's correct, but the DO 328 prop beats it size-wise.

Both runways were recently re-surfaced, and IIRC, RWY 03-21 was to have new edge lighting installed as well. A 100-ft wide runway though will not support aircraft larger than those mentioned above anyway, so larger airliners are out of question.

RWY 17-35 cannot be extended further south, unless they extend it as a displaced threshold. But then that means the probable intersection of it with 03-21 and the associated costs of tearing that up and rebuilding it again, so on and so forth. Probably not going to happen.
