Firstly, fly the Ac, not the FOQA or whatever... and remember, "it" cannot see anything you can't, but you can see the visual picture which it can't.

Ignore the ILS G/S below it's protected value, typically 200' unless LVPs in place etc. If you're not flying / been given an ILS approach, be cautious about flying with reference to it...

The VDEV bar is not a precision approach aid, so again, it's advice, but do not follow it slavishly. It is only as good as the FMC programming and the Nav accuracy... again, I'd ignore below typical NPA minima (500').

The best briefing / flying aid, and the one I see most poorly flown, is the VSI. 5x G/S or whatever as a datum. Then use an IAP check height / PAPIs to monitor the inital approach and get you stable / "in the slot". If you know the T'hd is 1500' inset, you could add 80' or so etc. Personally, I'd fly the IAP to minima/visual, and then slightly reduce the RoD.

"Stable" at 500' / 1000' does not mean "perfect". It usually means configured, on speed, some power, and on the correct V profile. You are essentially, in this case doing a visual approach, so in a typical jet, anything from 400'/m to 1000'/m I would suggest as acceptable. Outside those values, getting dodgy, G/A and try again?

There should be at least 2 sets of eyes as well. Brief to keep talking, elicit what the other guy thinks to the profile... "Tad high"..."Spot on" etc.

NoD

Look out the window and land the damn airplane. Pretty simple....
