Holding Entry Calculator

Determine direct, teardrop, or parallel entry for an IFR holding pattern using the inbound holding course, turn direction, and your aircraft heading at the fix. This free aviation calculator helps pilots and students with instrument training and holding pattern planning.

Calculate Holding Entry

Enter the holding inbound course, the published turn direction, and your aircraft heading when crossing the fix. The calculator will estimate the recommended holding entry.

IFR Holding Entry Calculator

How It Works

Inputs Used:
Inbound Course + Turn Direction + Aircraft Heading at the Fix
Possible Results:
Direct Entry
Teardrop Entry
Parallel Entry
Training Note:
Protected entry sectors are mirrored depending on whether the hold uses right turns or left turns.

This calculator is designed as a practical training aid for standard holding entry determination.

What Is a Holding Entry Calculator?

A holding entry calculator helps pilots determine the recommended way to enter a holding pattern based on the holding course, turn direction, and the direction the aircraft is arriving from at the fix.

In IFR flying, the standard entries are direct, teardrop, and parallel. Choosing the right entry helps keep the aircraft inside protected airspace and makes the hold easier to fly.

Why Pilots Use a Holding Entry Calculator

Holding Entry FAQ

What are the three standard holding entries?

The three standard entries are direct, teardrop, and parallel.

Does turn direction matter?

Yes. Right-turn and left-turn holding patterns use mirrored entry sectors, so turn direction is essential.

Is this a substitute for the AIM, procedures, or instruction?

No. This calculator is a training aid. Always follow current procedures, charted holding instructions, ATC guidance, and approved instrument references.

Why is holding entry sometimes confusing?

Holding entry depends on aircraft heading, inbound course, and turn direction all at once. A calculator helps make the geometry easier to understand.
