My interview was really straightforward, no big surprises with the LIDO charts. They realize most people haven’t been exposed to them. As long as you are able to find out the basics, that should suffice. I told my interviewer that I was unfamiliar with them so that may help.
There may be a LIDO DP, just read and brief it as you would off the charts you are used to. Take your time and hunt for the information you need so you don’t give them the wrong answer.
Again, these charts are not widely used among smaller outfits or general aviation so they aren’t expecting a masters level knowledge base on them.
Know what happens performance wise when dealing in the mountain flying environment.
All in all, be calm, cool, and collected. Just know that if they called you for an interview, they want you. If there is anything in your past, be honest and up front about it! Best of luck! If you have any questions, just send me a message.
