The primary justification to dump IAN is that so many people jack it up. Specifically, using IAN on approaches (RNP, etc) where it is not supposed to be used. And we are the only fleet to have it, so why be different.

News to me. High hot is one of the areas where IAN is specifically better than LAVS (ref Dec 23 fleet newsletter).

FIFY, sorta In all seriousness, does anyone have an accurate figure for the total WB's we had in 2019? That would be a relevant comparison to get the fuller picture, since there is some 'artificial' inflation of the number pre/post-paybanding.

Excluding 76-300. That’s a WB at NB pay so only those that paid WB rates.

The glide path generated by the FMC is based on barometric data which is impacted by temperature deviation from ISA temperature. During approaches with temperatures above ISA, the generated IAN glide path can be slightly higher than the visual glide slope indicator path, for example from a PAPI or VASI. In these conditions, if the crew follows the visual glide slope, the airplane will be below the IAN glide path which will cause a GLIDESLOPE alert to occur.

Ref Vol.2, 11.4.6
VNAV provides vertical profile guidance through the climb, cruise, and descent phases of flight. It is an uncompensated Barometric Vertical Navigation (baro-VNAV) system.
The Airway Manual Manual 5.3.1.3.2 notes 3 and 5 talk about the uncompensated baro-VNAV and the different approach types.
Bottom line, ILS and LPV are the only approaches not affected by non-standard temperatures.

IAN and VNAV both utilize a non-compensated path, and both are subject to temperature errors.
