How to change plane in campaign?

[TheStarOfAfrica]

Thank You for help. Yes, the favorite is Bf109F, but I like too a FW190, P40B/C(Tomahawk Mk.I, Mk.II), Ki61 and Hellcat


About campaign; but I don't think about campaign created by a "full mission builder", but a campaign original in the game, like Allied "NewGuinei" campaign in "Pacific Fighters". How to do that?

How to change the P39D-1 fighter to a P40B/C fighter in fighter campaign in original New-Guinei campaign in Pacific Fighters? How to do that? Because in one mission before in Pearl Harbor You flew on the P40B/C, but after in New Guinei is P39D-1; how change that to P40B/C?

Please help me!!!!
