The Air Caraibe memo states that about 30 minutes after the UAS event the crew reset both FMGEC to get rid of the SPD LIM red flag and to regain VLS indication on the PFD.
HN39 (or CONF or A33Zab):
If I might ask (without going to the memo), how did they reset the FMGEC's and how did they know, procedurally, to do it?
(BTW: saw your earlier question, and yes you can get the same 'latched' SPD LIM situation by inputting two airspeed discrepancies with no failure. Using a single offside ADR failure is just quicker than typing on an IOS keypad, but at least one side must incorporate the speed discrepancy, 2 or 3 ADR 'failures' and revivals will not do it. Once on the ground, you can reset both the SPD LIM & FC law by cycling the generators off and on.)
