d. Load factor and accelerated stalls
Aerodynamics associated with steep turns, including: d. Load factor and accelerated stalls
Bottom line
The accelerated stall would most frequently occur inadvertently during improperly executed turns, stall and spin recoveries, pullouts from steep dives, or when overshooting a base to final turn.
Key numbers
| Number | What it means |
|---|---|
| 3 Gs at bank greater than 72° in a steep turn | Load factor |
| 100 knots at 4 Gs for an aircraft with 50-knot unaccelerated stall speed | Stall speed |
| beyond approximately 45° of bank | Significant loads |
