Apparently Comair the first carrier has a firm policy to always go-around with a windshear alarm. Many carriers do not require a go-around when there are not thunderstorms or frontal passages. The systems were implemented originally because some misguided pilots crashed after flying through thunderstorms on short final. Micro-bursts are really the only events that exceed aircraft performance capabilities. The current St.Helena carrier SA Airlink intends to try to fly through the turbulence. Large control movements on short final are something that's rare in today's "stabilized approach" era. In preparation, the St. Helena route Airlink pilots have been hand flying the E190 all the time except in cruise to get their skills up. A prior ETOPS qualification flight made a lot of landings with the heavy winds which were "eye opening" but they are succeeding. The windshear alerts are ignored and the aircraft wrestled through the turbulence and if the energy is right at the touchdown zone, landed. That's what you get paid big bucks for. The chief pilot and training director are among the qualified Captains on the route. They haven't had to go-around yet.
The E190 can also land downwind where-as the Comair B 737-800 could not on the RESA restricted runway length.
