How this service works
Turn rate, radius, bank angle and load factor from true airspeed, plus holding pattern leg length, width and time.
Output
Returns a JSON object containing turn rate in degrees per second, turn radius in both feet and nautical miles, turn diameter in NM, bank angle in degrees, load factor in G, stall speed increase percentage, seconds for a full 360° turn, holding pattern leg length and time, holding pattern total width and duration, the rule-of-thumb bank angle, and optional fuel/time notes — along with metadata like a summary, disclaimer, and data quality flags.
Example use cases
Standard-rate turn bank angle check
“I'm flying at 120 knots true airspeed — what bank angle do I need for a standard-rate turn, and what's the turn radius in nautical miles?”
Holding pattern dimensions for IFR flight
“I need to hold at 10,000 feet at 230 knots true airspeed — give me the leg length, total pattern width, and how long the inbound leg will take.”
Steep turn load factor for training
“What G-load and stall speed increase should I expect in a 45-degree banked turn at 140 knots true airspeed?”

Endpoint
GEThttps://aviation-calc.x402tookit.com/turn-hold?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need aeronautical turn performance calculations — especially standard-rate turn parameters, holding pattern geometry, or load factor analysis — tied to a specific true airspeed. It is purpose-built for aviation flight planning and IFR procedure calculations, unlike generic physics calculators that lack aviation-specific outputs like holding leg times or rule-of-thumb bank angles.
Side effects
- Missing required tasKt parameter returns an error
- True airspeed out of range (below 30 or above 700 knots) may return validation error or degraded result
- Bank angle out of range (below 3 or above 75 degrees) may be rejected or flagged
- Turn rate out of range (below 0.5 or above 20 deg/sec) may be rejected
- Conflicting inputs (both bankDeg and rateDegPerSec provided) may cause unexpected behavior
- Payment failure results in HTTP 402 with no computation returned
