Hello and welcome, Carbon here and I bring to you my definitive cold start video. I started these cold start videos over on the VFA 105 channel and have now made and brought my definitive one over to here. I am a Crew Chief of 15 years and am very familiar with launches. Over the multiple bases and blocks I've been to/worked, no launch was really the same. There's a baseline 1 checklist and then there are the location supplements to that checklist that vary base to base. Whether its performing SEC check before EPU or vice versa, big flight control movement checks before trim etc. something always differs, and that's the beauty of it. A realistic viper start can be argued to be really anything, as long as the boxes are checked.
