They even built a runway specifically for the DHC8.
PLH's original tarmac runnways were 06/24 & 12/30, 06/24 couldn't be extended and on the 12/30 heading they couldn't extend enough to accommodate DHC8's thus they realigned building runway 13/31.
Watched a Caravelle do a touch and go on the old, half tarmac half grass, runway 30 one day ... that was an interesting sight to see
