Holdover time is an estimated period during which applied anti-icing fluid is expected to protect treated aircraft surfaces from specified frozen contamination under stated weather conditions.

Aviation Glossary

**Term:** Holdover Time

**Category:** Airport & Ground Operations

## Ground Operations Context

Holdover Time is used during aircraft servicing, turnaround or airport operations. Ground equipment and procedures must match the aircraft type, local airport rules and the operator's approved procedures.

## Operational Use

It is a planning aid rather than a guarantee; crews must monitor conditions and complete required contamination checks before takeoff.

## What to Confirm

Confirm equipment compatibility, trained personnel, local procedures, safety zones, weather limits and responsibility for any ground damage or delay before the service is accepted.
