Final answer:
While the provided references relate to projectile motion which is optimal at 45 degrees for maximum range without air resistance, they don't directly answer the aircraft approach question. However, practical aviation knowledge suggests that approach angles should be safe and typically less than 90 degrees.
Step-by-step explanation:
Optimum Angle for Maximal Projectile Range
The question seeks to identify the maximum intercept angle for an aircraft that is less than 2 miles from the approach gate. While the provided reference information discusses the optimum launch angle for projectiles to achieve the maximum distance, which is 45 degrees, this principle does not directly answer the question related to aircraft approach gates. However, using the understanding of projectile motion, we can infer that angles in any interference patterns, including approach paths for aircraft, cannot be greater than 90 degrees. Additionally, the context of aviation would suggest that extreme angles greater than 30 degrees are typically avoided for safety. While the exact maximum intercept angle for an aircraft approach is not provided, the answer would most likely be within reasonable operational limits and less than 90 degrees, with more conservative approaches favoring angles below 30 degrees for safety reasons.
