The January deep freeze has hit northern MB. I went to YQD to shovel out my Mooney and plug in for a couple of CASARA flights tomorrow (Sunday) starting at 7:30 a.m. local. I was supposed to fly to Swan River and pick up a load of navs and spotters and bring them to YQD where we would meet the Herc and do a couple of exercises in the area, and then fly them back home. The high today was -26C and the sock was straight out. The forecast low is for -32C tonight with a forecast high of -24C tomorrow afternoon. CASARA has a -25C limit on TRAINING missions, although the real search is PIC's discretion. I've lived in the area for 30 plus years and have seen my share of cold. If I recall, my coldest takeoff was at -32C last winter. Density altitude was somewhere around 5,000 below sea level. Pretty good performance!
My question is, what are your temperature limits for flying? Are they set by your company if you work for one, or set by the aircraft manufacturer, or set by your own common sense? Does single engine, twin or turbine make a difference? Input would be much appreciated.
