Which application can crew members reference for HOT calculations?

Crew members can reference Kilo Lima Management's Holdover Calculator for HOT (Holdover Time) calculations because it is specifically designed for this purpose. Holdover Time calculations help determine how long an aircraft can remain on the ground in winter weather conditions while still being safe for takeoff. The calculator takes into account the type of de-icing fluid used, the ambient temperature, and other relevant factors to provide accurate estimates.

The other applications mentioned do not serve this specific function. The JetBlue Management app and the Weather Watch app may provide various tools for flight planning and monitoring weather, but they do not include specialized features for Holdover Time calculations. Similarly, the AOPA Flight Planner focuses on general flight planning rather than specific weather-related calculations like HOT. Therefore, Kilo Lima Management's Holdover Calculator is the most relevant tool for crew members needing to perform HOT calculations.
