⚠️Landing Factors to Consider
⚠️ Tailwind
A 10 kt tailwind increases landing distance by approximately 50%. Avoid tailwind landings whenever possible.
🌡️ High Density Altitude
Every 1,000 ft of density altitude adds ~3-4% to landing distance. At DA 5,000 ft, expect ~15-20% longer rollout.
✓ POH Guidance
FAR 91.103 requires you to check runway length vs. planned landing distance. CFR Part 135 requires 60% runway rule.

Pilot Tip
The FAA recommends a fuel reserve of at least 45 minutes for VFR day flight. Always plan for more — weather diversions happen.

📊Standard Climb Profile
Vx vs Vy: Vy gives best rate of climb (max altitude in min time). Vx gives best angle of climb (max altitude per unit distance — use for obstacle clearance).
| Altitude Band | Expected Rate | Time | Notes |
|---|---|---|---|
| SL – 2,000 ft | 700-800 fpm | ~3 min | Best performance |
| 2,000 – 4,000 ft | 600-700 fpm | ~3 min | Standard |
| 4,000 – 6,000 ft | 500-600 fpm | ~4 min | Standard |
| 6,000 – 8,000 ft | 400-500 fpm | ~4-5 min | Degrading |
| 8,000 – 10,000 ft | 300-400 fpm | ~5-7 min | Plan for longer |
| Above 10,000 ft | <300 fpm | Varies | Use N/A rule |
