Holding Pattern Entry Calculator

Enter the inbound holding course, whether the turns are standard (right) or nonstandard (left), and your heading as you arrive at the fix. The recommended AIM entry — direct, teardrop, or parallel — is shown with a diagram, the teardrop heading, and, if you add an altitude, the maximum holding speed and inbound-leg time. Results update as you type.

The hold and your heading
Turns

The inbound course is the heading you will fly to the fix once you are established in the hold (the reciprocal of the outbound radial, for a VOR hold). Determine the entry from your heading at the fix; AIM allows ±5° of heading as good operating practice.

Altitude and speed optional

Altitude sets the maximum civil holding speed (200 / 230 / 265 KIAS) and whether the inbound leg is 1 minute or 1½ minutes. TAS is only used to estimate the length of a timed leg in nautical miles.

Direct, teardrop, and parallel entries

AIM 5-3-8 and Figure 5-3-4 divide the area around a holding fix into three sectors with a 70° line on the holding side. Measured by the aircraft’s heading as it arrives at the fix, the sectors are:

On a sector boundary, or within 5° of one, either adjacent entry may be used (AIM 5-3-8 j.8.(d)). Nonstandard (left-turn) holds use the same 70° line on their holding side; the sectors are mirrored about the inbound course.

Holding speeds and timing

Civil maximum holding speeds are 200 KIAS up to 6,000 ft, 230 KIAS from 6,001 to 14,000 ft (some patterns are posted at 210), and 265 KIAS above 14,000 ft. A charted speed in parentheses overrides the table. Time the inbound leg 1 minute at or below 14,000 ft MSL and 1½ minutes above; start outbound timing abeam the fix or when the outbound turn is complete. Triple the inbound wind-correction angle on the outbound leg.

Worked example

Hold with an inbound course of 360°, right turns, heading 090 at the fix, 4,000 ft, 100 kt TAS:

Frequently asked questions

How do I know if a holding entry is direct, teardrop, or parallel?

Compare your heading at the fix to the inbound course. Direct is the large 180° sector; teardrop is 70° on the holding side next to the outbound; parallel is 110° on the non-holding side. Within 5° of a boundary, either adjacent entry may be used.

What heading do I fly for a teardrop entry?

Outbound plus or minus 30°, toward the holding side. For a standard right-hand hold that is outbound minus 30°. Fly it for one minute (or 1½ above 14,000 ft), then turn to intercept inbound.

What are the maximum holding speeds?

200 KIAS to 6,000 ft, 230 KIAS from 6,001 to 14,000, 265 KIAS above, unless a slower speed is published.

How long is a holding leg?

1 minute inbound at or below 14,000 ft MSL, 1½ minutes above. DME or RNAV legs use a published distance instead.
