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.
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.
This calculator is designed as a practical training aid for standard holding entry determination.
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.
The three standard entries are direct, teardrop, and parallel.
Yes. Right-turn and left-turn holding patterns use mirrored entry sectors, so turn direction is essential.
No. This calculator is a training aid. Always follow current procedures, charted holding instructions, ATC guidance, and approved instrument references.
Holding entry depends on aircraft heading, inbound course, and turn direction all at once. A calculator helps make the geometry easier to understand.
