Sure, let’s break it down. First, get the latest mountain weather—high winds and jet streams can mess with your climb. Next, map the ridge lines and identify key waypoints so you stay in clear air. Keep an eye on the engine temperature; at that altitude the margin is tight. Make sure you have a robust fuel reserve for an emergency descent or a detour. Lastly, plan a backup runway in case of sudden weather change, and keep the crew in sync on every step. Anything else you’re worried about?
