A question for landing limits in Canada, can you confirm I have this right?
#1 say the alt airport had a x-wind of 13kts@35’ off runway with a CRFI of .3 Notamed, then it can’t be used. (ie will be CFRI of 3.6)
#2,
Say we have no CRFI reading but the RSC says one inch snow covered, I go to the RSC table and see that is 0.25-.3, say I use 2.7 as my CRFI from my CFS. Lets say I am in a PA-31 and my ldg distance dry and unfactored is 2400feet, I go to the No Discing table over the page and 2400feet at .27 is 5470 feet required. Oh but I need to be able to land in the first 70% of the runway available, 5470x1.3=7111feet.
Is that how you do it? So a PA-31 needing 2400 feet dry will need 7111 to land legally with 1’ of snow, which is very common at some airports.
