You have a better chance IMHO of surviving Scrambles if you delay your take-off for what might seem a long time, maybe a minute or two. By waiting you take away the enemy advantage, angle of attack I think it's called. Anyway rather than being a target with no advantage you then have a chance of engaging them while they are engaged with your squadmates and or "A" flight. You can get on their tail. Now it may seem that you are not doing your part and that your countrymen will perish but actually it's not real life and even if some pilots go down they will not be lost/dead. Just an approach if you want to better your odds with a campaign pilot you would hate to lose.
