Flying by Vertical Angles

Aircraft performance parameters are typically expressed as measurements of speed (indicated and true), altitude and vertical speed. Often overlooked is angle as an expression of performance. Angles are a terrific tool for estimating glide and approach performance, avoiding clouds and storms and avoiding obstacles and terrain on takeoff. There are two related subjects: how to measure angles while in flight, and how measured angles can solve in-flight problems. Lets start with measurement.

Key Takeaways:

• Angles are an often-overlooked but vital aircraft performance parameter that, unlike speed or altitude, are particularly useful for estimating glide, approach, and terrain avoidance.
• Specialized tools like clinometers (for vertical angles, including smartphone apps) and handheld sighting compasses (for horizontal angles) enable pilots to accurately measure these critical angles in flight.
• These measured angles provide practical solutions for in-flight problems, such as calculating engine-out glide distances, ensuring terrain clearance during takeoff, planning optimal descents and approaches, and making informed decisions regarding cloud topping or storm deviations.
