I am coming up on my checkride(tomorrow) for my instrument rating. Any help with these two questions would be amazing. Thank You in advance.
First Question: What does U mean if it follows a runway number. For example at X21(Arthur Dunn Arpk) there is a runway titled 22U.
Second Question: Because X21 is my alternate and it only has 2 GPS approaches, do I need an alternate. I know that if your primary airport only has GPS approaches you must file an alternate to another airport with an approach other than GPS. Does this apply all the time or just when weather is outside of the 1-2-3 rule/alternate requirements?
