Synopsis
Air carrier flight crew reported wind gusts on approach; unstable indicated and vertical speeds; PFD display problem; and poor crew coordination resulted in TA and late touchdown.
Narrative
Vectors to GPS XX ZZZ; First Officer (FO) GPS did not display Flight Path Angle (FPA) on Primary Flight Display (PFD). Captain's side displayed what appeared to be correct FPA. Due to varying wind conditions on final; varied VSI was required to maintain FPA. This was briefed and expected. At some point on final with the runway in sight and on FPA on the Captain's aide; we received a terrain caution. Captain saw momentary increase in VSI due to changing winds; and recognizing the aircraft was on glide path in a safe condition; verbally told the FO (hand flying at this point) to level off momentarily. The caution went away and confirmed it was due to changing VSI. We continued the approach at this point. Due to changing wind conditions and gusts in ZZZ; FO was stable within 3 kts of ref approaching the threshold. However due to a shifting aim point and wind gust; speed increased to ref +10 during the round out. Captain should have verbally intervened sooner. End result was a long round out and late touchdown. Captain elected to take the aircraft and get it on the ground. Aircraft was slowed to taxi speed with approximately 1500 ft. remaining. Captain should have verbally intervened sooner to help during challenging wind conditions. Captain was letting newer line FO get experience with an approach into ZZZ. Captain had already taken when they thought would be the hardest leg earlier in the day and tried to give the appropriate legs to the FO. This was one of those times where the Captain should have elected to make the landing.
Second reporter narrative
Radar vectors to RNAV XX ZZZ. Flight Path Angle; (FPA) not displayed on First Officer's (FOs) Primary Flight Display (PFD) but; was displayed on captains PFD. The VSI required to maintain FPA varied due to wind conditions and on final received a terrain warning. Was told to level off momentarily and the warning went away. Visual conditions so we continued the approach. Continued a stable approach and with the changing in winds I flared a little too early. Floated a bit and touched down long. Captain elected to take controls to get us stopped in plenty of time.
