Tips for better piloting
WHY 3°? THE PERFECT GLIDE SLOPE
The 3° glide slope is the global standard for most approaches. It gives pilots a stable, safe, and efficient descent profile.
While some airports require steeper approaches due to terrain or obstacles, 3° remains the default almost everywhere in the world.
WHY 3° MATTERS
PAPI lights and visual glide paths are set for 3°. If you fly higher than this, you’ll float and land long. Fly lower, and you risk an unstable or unsafe approach.
Staying on the 3° path helps you:
• Maintain a stable approach
• Control your energy
• Touch down in the correct zone
QUICK MATH FOR A 3° DESCENT
Rule of thumb:
Multiply your groundspeed by 5 to get your descent rate.
Example:
90 knots × 5 = 450 feet per minute
Another way to remember it:
Divide groundspeed by 2 and add a zero.
UNDERSTANDING THE NUMBERS
A 3° glide slope equals a 5.24% gradient
1 nautical mile = 6076 feet
6076 × 0.0524 ≈ 318 feet per nautical mile
That means you lose about 300 feet per mile on a standard 3° approach.
WHEN TO START YOUR DESCENT
Top of Descent Rule:
Divide the altitude you need to lose by 300
Example:
From 11,000 ft down to 2,000 ft = 9,000 ft to lose 9,000 ÷ 300 = 30 NM before the airport.
Simple. Practical. Effective.
PILOT TIP
Start your descent slightly earlier than calculated.
This gives you time to stabilize, configure the aircraft, and arrive at pattern altitude smoothly.
Blue skies, tailwinds, and safe flying.
Keep learning. Keep improving.
