Aerodynamic & Operational Physics
- Mathematical principle: 1 NM off track at 60 NM distance flown equals 1° Track Error Angle (TE = (Distance Off / Distance Flown) × 60).
- Closing Angle to destination: CA = (Distance Off / Distance Along) × 60.
- Total Heading Correction to intercept destination = Track Error Angle + Closing Angle.
CASA & FAA Exam Gotcha Alert
CASA Exam Trap: Remember to ADD TE and CA together to alter heading to hit destination, or double TE for equal distance leg interception.
Frequently Asked Questions & Exam Explanations
What is the 1-in-60 rule formula?
