Now is there an aircraft that can reasonably use the 1850m runway with that sort of tailwind? That is, one that can carry a commercially viable load of passengers.
Not sure, but the only one that comes to my mind is the CS100. Impressive short field and high angle capabilities, sufficient range, smaller and lighter than the 737-800 and with ca. 120 seats could be a viable option.
Comair probably too conservative and not flexible enough to add (or replace) such a new aircraft type to its fleet But I am sure there are also other thinner routes in Southern Africa where the CS100 can be used,
Even Air Namibia should have a look at the CS100.
As far as I know several lessors will offer the CSeries in 2017 if leasing is an option.
