Narrative: On very short final we received a 'GLD [Ground Lift Dumping] Disarmed' Caution message. The GLD was confirmed in the AUTO position. The Captain said 'I'll just pull the spoilers if GLD doesn't deploy; if that's OK with you.' That sounded acceptable to me so we continued the landing. Upon touchdown GLD did not deploy. The aircraft bounced and became airborne again. I set the aircraft down again and the Captain deployed the flight spoilers. The remainder of the landing was uneventful. The touchdowns were firm; but not hard. Once at the gate the Captain explained our out of the ordinary landing to the passengers. No faults were found with the GLD system by Maintenance.When the message appeared I didn't think it would be an issue at all. I thought of it as a nuisance message. The Captain's suggestion to manually pull the flight spoilers seemed perfectly acceptable to me at the time. After talking about the event later; we both agreed that we should have executed a go around and dealt with the GLD fault before attempting a landing. Upon reviewing the QRH though; I'm not sure I would have been comfortable performing the checklist. The first item is put the GLD switch into the MAN ARM position. With a malfunctioning GLD system; I would be afraid the GLD's would deploy in flight.


Second narrative: Despite an OK outcome; my decision here was terrible. Obviously; we should have gone around and dealt with this properly. I was not fatigued per the definition; but I was certainly tired. I got off duty late the previous night; to bed around an hour after; woke less than 5 hours later; and had an eight hour turn. It was a long flight and I was dragging some. This may have affected my thinking; or the lack thereof.The main thing here is to do things like you've been taught; and don't out think yourself. My advice to student pilots for many years has been consistent: If it crosses your mind that maybe you ought to go around; and then go around. This thought will only cross your mind rarely; so act when it does. Don't stop to ponder; or hope that somehow whatever it is will fix itself. I give good advice; and should have taken it too.


Synopsis: The flight crew of an EMB-145 had second thoughts about their decision to continue to a landing and manually deploy spoiler vice going around following receipt of a GLD [Ground Lift Dump] NOT ARMED warning on short final.
