BARO VNAV Temp Compensation @ RKSI

[chx230]

As we all know, temperature compensation is necessary during LVNA/VNAV approach by using the Baro-VNAV while the temperature is extremely low. In most of the airport approach charts (Jeppesen), it states "For uncompensated Baro-VNAV systems, LNAV/VNAV not authorized below -15℃ or above 49℃". However, I found that for RKSI it only states "Baro-VNAV not authorized below -20℃". Does that mean I can NOT execute the approach even though my aircraft has temperature compensation function?

From the FAA: (jeez, look at the date)

From the Feb 2014: FAA Safety brief. Perhaps this is why they have decided not to allow for temperature compensation?

chx230,

At my company we are not allowed to fly that approach to the LNAV/VNAV minima as the obstacle clearance is compromised outside of the temp limit. However, we can still fly the approach to LNAV minima (with temperature corrections) as the limit does not apply to this approach. Note that the LNAV approach has an MDA, so we add 50' as well as the temp correction.
