Glideslope path

[brunovinci 2]

I fly the CJ2 with the GTN 750/AP mods.

When attempting a regular ILS approach (no  LPV available at this Brazilian airport):

- I intercept correctly the locailizer
- the GTN is on VLOC
- I capture without problem the glideslope
- further, the glide path indicator starts moving
- when the indicator is centered, I engage APPR

At this time, although my approach speed and configuration are correct, the CJ2 does not follow the glide path and I have to do it manually.

I would appreciate any one telling me what is wrong.

Do not wait until the glideslope is centered to engage APPR.  Engage APPR when established on initial approach altitude with ALT hold on and well below the glideslope.
