I think you gave the math for the ACI or Angle COSINE indicator, NOT the Angle Degree Indicator. The Angle Degree Indicator give values like 5,10,15,20,25 etc
HireHeroes_JB >> If you choose, the ADI because you want to know the angle you might want a multiplier card or Ti scientific calculator too so it will give you a cosine calculation (Degrees X COS button)Distance = gravity range. OR just get the ACI
