The glideslope doesn’t stop at 200’ AGL.
When you follow the glideslope guidance down to the ground you’ll impact in the touchdown zone. There is no reason to deviate from the glideslope once at minima.
I’ll need to look it up but I believe the GS is certified to half its minima, so 100’AGL in case of a CAT 1 ILS.
Even then the ILS critical area should be clear.
You’re supposed to be flying a stable approach, aka configured on speed on glide path with the appropriate power setting.
Deviating (significantly) from your vertical path to the extend of a GPWS alert just made your approach unstable and cause for a go around.
Company I work for it’s a mandatory go-around on your second “Glideslope” warning.
There is a minimum runway length for ILS approaches. There is no ILS to a “short” runway. Your performance calculations do not include a “tuck under”.
I’m with your safety manager.
Weather at minimums is not the time to F around.
