Yes. When the tables are updated by authorities, our website also makes the necessary updates in ten working days.

Allowance times are for use with undiluted (100/0) fluids applied unheated on aircraft with rotation speeds of 100 knots or greater.

The LOUT is the lowest temperature at which a fluid has been determined to flow off aircraft critical surfaces in an aerodynamically acceptable manner (AS5900) while maintaining the required freezing point buffer.

The freezing point buffer is 7 °C below OAT for Types II, III, and IV fluids and 10 °C below OAT for Type I fluids.

A weather report issued regularly at intervals of an hour or half an hour describing weather conditions at an airport.

There is no standard amount to be applied; however, an approximate amount can be determined based on some elements such as surface area, application experience. For anti-icing application the fluid should be applied at a rate of at least 1 liter per square meter. The quantity amounts we provide on this website are based on these factors.

Fluid type, brand, OAT and LOUT are key elements that determine mixture amounts

The freezing point of the Type I fluid, generally should be 10°C lower than the OAT. The freezing point is generally determined by using a refractometer and chart provided by the fluid manufacturer.

Anti-icing code is only for anti-icing application, and it shall be communicated by supervisor to the cockpit after the anti-icing application is completed.

Because the flight crew must make the application records and data entries into AML
