Hi All,
Very interesting topic here.
On the MD-11 the CADC's DO NOT AUTOMATICALLY compensate for low temperature versus altimeter corrections!!
In fact ATC, if under radar control, WILL have allowed for the low temperature when giving you radar vectors for final approach to an ILS.
All NON precision approaches require pilots to add their own altitude allowances to procedural heights etc and MDA, according to the temperature.
Terrain clearance can be a problem with low temperature and barometric pressure so watch out and take care out there this winter!!
ATB,
Jon.
