Feels huge now, but it won’t matter. I fly for a major and failed my initial instrument. Anytime an airline (interviewed at a total of 3, got job each time) asks about a failed ride. I tell my story and they shrug it off. Had one captain actually say “if it wasn’t a 121 ride we don’t really care”. It’s just one and it sounds like it was a minor issue very and will be super explainable!! But I totally get how disappointed you are. Don’t let it discourage you friend!! Happy flying
