Full Description

This SAE Aerospace Standard (AS) establishes the aerodynamic flow-off requirements for SAE AMS 1424 Type I and SAE AMS 1428 Type II, III and IV fluids used to deice and/or anti-ice aircraft: a. with takeoff rotation speeds generally exceed approximately 100 knots, with time from brake release to rotation speed greater than 20 s, typical for large transport type jet aircraft. This procedure is referred to as the High Speed Ramp Test. and/or b. with takeoff rotation speeds generally exceed approximately 60 knots, with time from brake release to rotation speed greater than 15 s typical for commuter type aircraft. This procedure is referred to as the Low Speed Ramp Test.

The objective of this standard is to ensure acceptable aerodynamic characteristics of the deicing/anti-icing fluids as they flow off aircraft lifting and control surfaces during the takeoff ground acceleration and climb.
