Aerodrome Weather Reporting So I fly out of Winsor ON Canada I only hold a recreational permit which means I m not exactly a frequent flyer just going out for fun every once in a while However while checking the weather this date I found this METAR METAR CYQG 161800Z CCA 29012KT 15SM BKN240 BKN270 08 M07 A2989 RMK CS3CI2 CONTRAILS SLP124 For those that can t read these here s a simple breakdown There s some unnecessary stuff for this perticular article then in the remarks section RMK CS3CI2 CONTRAILS SLP124 it mentions contrails in the area Now like I said I don t fly much But is there any reason a small operation airport like Windsor would need to declare contrails in the area Anything above 3 000 feet over Windsor is Detroit airspace so they would want to post this right
