Formation Flying: Station Keeping - 02/28/12 09:39 PM
I created this simple mission to practice straight and level station keeping with an AI Lead. Not as fun as a human flight partner, but much more reliable and forgiving!

In this mission you are air-spawned off the wing of an AI A-10C that is flying a rectangular route (WPs 0 through 3) at a constant altitude and airspeed. The rectangle is 20 NM by 10 NM so you have plenty of time between waypoints to practice station keeping and cross unders. The AI will continue to fly this rectangle in a loop until it is bingo fuel.
I strongly recommend reading up on formation flying before attempting it here. Paulrkiii has a fantastic guide that I will link to (when I get permission and find a working link!), in the meantime, here are some pointers:

I strongly recommend reading up on formation flying before attempting it here. Paulrkiii has a fantastic guide that I will link to (when I get permission and find a working link!), in the meantime, here are some pointers:
- For close fingertip formation, aim for about 45° behind the lead with some wingtip separation and stack down. See the sight picture below to see what Lead's aircraft should look like when you are in position.
- When joining up, first get on the right angle back, then close distance to lead along that line until you're in position.
- You are never in formation. You are always making corrections to get into formation.
- Anticipate power and control input changes before you need them so you are always making small corrections, not large ones.
- Smooth and steady on the inputs. Large, jerky motions scare Lead and just makes your position problem worse.
- Tiny changes in throttle make big differences, but it takes time to see the effect. Be steady and patient, but stay on top of it before you get far out of position.
- Behind too far ahead (aka "acute") is much more dangerous than behind too far behind (aka "sucked"). Don't do either.
- NEVER turn belly up to Lead!
- If the only way to stop an overrun is to turn belly up to Lead, DON'T! Descend and coast under Lead, slow down and fall back behind Lead, then creep back up into position.
- You are making rate changes with your controls, not position changes. If you find yourself wildly oscillating (up/down, left/right, or back/forth), STOP! First make the rate of change stop, then slowly scoot into position.
- Work on station keeping first, then try cross unders to switch sides.
