Flak
This page describes flak and how it works.

Flak is created from gunfire when enemy planes fly overhead.

The way that flak works when planes fly over a sector is:
 * Sector flak is fired.  Up to a maximum of 14 guns can fire.

They're then scaled by twice your country's tech factor. So, for example, if you had 14 guns firing, and have a tech factor of 35%, you would have a total of 14 * .35 * 2 = 10 (after rounding) guns firing. In  addition, if you are pin-bombing a land unit or a ship, when you make your bombing run, the specific unit/ship you are bombing gets to fire flak  at  you again. This  number  of  guns  firing flak in these cases does NOT saturate. Land units do not need capability flak to fire here.
 * Land unit flak is then fired.  Only 'flak' capable units will fire in this volley (see Info: show), and each point of aaf counts as 1.5 flak guns.  Flak saturates at 14 guns, and is then scaled by unit tech factor.
 * Ship flak is then fired.  Flak saturates at 14 guns, and is then scaled by unit tech factor.

The formulas for determining the # of guns fired from a sector in a general volley is:

Sector Flak:
guns = (guns in sector); if (guns > 14) guns = 14;

Ship:
guns = 0; for (each ship in the sector) guns += min(guns, guns able to fire) if (guns > 14) guns = 14;

Land unit:
guns = 0; for (each land unit in the sector) guns += (aaf rating) * 1.5 if (guns > 14) guns = 14; Then, for each of the above general flak volleys, the # of guns is scaled like so: firing = guns * (average techfact) * 2; where average techfact is the average tech factor of everything that could fire in this volley, regardless of saturation. Sectors use their owner's tech factor.

On pinpoint bombing runs, the # of guns firing is determined by:

Ship:
guns = min(guns, guns able to fire) * (techfact of ship) * 2;

Land unit:
guns = (aaf rating) * (techfact of unit) * 3; techfact is determined by: techfact = (50.0 + tech) / (200.0 + tech); Once  the  number  of flak guns firing has been determined, the planes have to fly through it. The plane may have to fly through flak up to 4 times in  each sector, depending on circumstances. They are: To  figure out the damages that a plane takes each time it flies through flak, the following formula's are used: flak = # of guns firing. flak = flak - (planes defense); if (plane is not tactical) flak = flak - 1; if (plane is stealthy) flak = flak - 2; if (plane is half stealthy) flak = flak - 1; if (flak > 8) mult = flaktable[16]; else if (flak < -7) mult = flaktable[0]; else { flak += 8; mult = flaktable[flak]; } mult *= flakscale; damage = ((random number from 1 to 8) + 2) * mult; if (damage > 100) damage = 100;
 * 1) Fly through general sector flak (if any)
 * 2)     Fly through general ship flak (if any)
 * 3)     Fly through general unit flak (if any)
 * 4)     If pin-bombing, fly through specific unit or ship flak (if any)

plane's eff = (plane's eff) - dam; if (plane's eff < 10%) plane is shot down else if (chance((80 - (plane's eff)) / 100)) plane aborts mission otherwise the plane continues on it's mission For the above, use this table: flaktable[0] = 0.132 flaktable[1] = 0.20 flaktable[2] = 0.20 flaktable[3] = 0.25 flaktable[4] = 0.30 flaktable[5] = 0.35 flaktable[6] = 0.40 flaktable[7] = 0.45 flaktable[8] = 0.50 flaktable[9] = 0.50 flaktable[10] = 0.55 flaktable[11] = 0.60 flaktable[12] = 0.65 flaktable[13] = 0.70 flaktable[14] = 0.75 flaktable[15] = 0.80 flaktable[16] = 1.1305 and a flakscale of 1.75
