Holding Procedures
Holding Procedures
Definition
A holding procedure is a predetermined racetrack-shaped pattern flown by aircraft to maintain position while awaiting further clearance. It is typically used during delays, traffic sequencing, approach procedures, or when weather or airspace congestion prevents immediate continuation of flight. Holding patterns are defined in instrument procedures, but can also be assigned by ATC dynamically.
Purpose
- Maintain safe vertical and lateral separation when aircraft cannot proceed immediately
- Provide a buffer zone during arrival peaks or when approach delays occur
- Allow pilots to troubleshoot or coordinate before continuing flight
- Used during instrument approaches, emergency diversions, or airspace restrictions
Structure of a Holding Pattern
- One fix or waypoint (usually a VOR, NDB, or RNAV point)
- Two legs:
- Inbound leg toward the fix (usually 1 minute below 14,000 ft; 1.5 min above)
- Outbound leg away from the fix (timed or distance-based)
- Turns: Standard (right-hand) unless otherwise specified
- Published on instrument charts with radial, direction, altitude, and speed
Types of Holding Procedures
Phraseology Examples
Entry Procedures
Three standard entries depending on your inbound heading:
- Direct entry: Turn directly into holding pattern
- Parallel entry: Fly outbound leg, turn opposite direction, then rejoin
- Teardrop entry: Fly offset from fix, then turn back to intercept
The correct entry is chosen based on your bearing relative to the fix — ICAO or FAA rules may differ slightly.
Speed Limits in Holding
| Altitude | Max Holding Speed |
|---|---|
| ≤ 14,000 ft | 230 knots IAS |
| > 14,000 ft | 240–265 knots IAS (region-dependent) |
Speeds are regulated to ensure pattern containment and safe separation.
VFR Holding
- Not as formalized as IFR holds
- Often instructed as “orbit” or “hold over point X”
- Used at uncontrolled airfields or when waiting for entry into airspace
Example: “Hold over reporting point November at 2500 ft until cleared to enter CTR.”
Holding and Fuel
Prolonged holding can be fuel-critical. Pilots must:
