The E190 is currently the only aircraft available on the used market that has the range and can, in a pinch, land downwind at HLE with the available 6396 ft. of grooved, concrete runway restricted by 240 m. + RESAs to 5036 ft. legal landing distance. The RMS is wearing out and requires massive subsidy exceeding the passenger ticket price.
Single runway remote island airports usually have rules that once an inbound aircraft has reached the point of no return, no other aircraft operations are permitted until the aircraft has landed to make a blocked runway situation very remote. I believe Easter Is. is in this category. The 240-300 m. RESAs at HLE are the cause of most of the problems. If they were 90 m., bigger, more efficient aircraft could operate there. The B-757-200 would be the most economical. Stretched 737s and A320+/- require more runway when they get heavy particularly at maximum landing weights and downwind. I just watched the NG show about the Garuda 737 that touched down 2800 Ft. from the threshold 80 kts. over Vref with only 5º flaps! How does any RESA make an airport safe from pilots like that? He had 21 years with the company.
