Narrative:
While on the ILS runway 19 teb we were established on the localizer inside of tuggz and were cleared for the ILS approach. We were level at 2;000 feet with the autopilot engaged. As the glideslope captured the aircraft made an abrupt climb. A correction was made to prevent continued climb on the glideslope and the aircraft followed a visual path backed up by the localizer. The climbing action was sudden and unexpected. We queried the controller on the unexpected deviation in the glideslope and explained what had occurred. Further reading on this subject reveals that it is a known problem at teterboro and is well known by the teterboro users group. I feel given the severity of glideslope deviation and the high likely hood of occurrence that this needs to be addressed.
