Airframe icing is ice accretions on the airplane, except for the propulsion system. lowing it to run back and off the protected surface or freeze on non-critical areas.
Where and When Icing Occurs
Pilots can encounter icing in any season, anywhere in the country, at altitudes of up to 18,000 feet and sometimes higher. Small aircraft, including [...]

An ice protection system (IPS) is a system that protects certain critical aircraft parts from ice accretion. To be an approved system, it must satisfy the requirements of 14 CFR 25.1419 which requires:
If the applicant seeks certification for flight in icing conditions, the airplane must be able to safely operate in the continuous maximum and [...]

Automatic Cycling Mode is a mode of operation of the airframe deicing system that provides repetitive cycles of the system without the need for the pilot to select each cycle. This is generally done with a timer, and there may be more than one timing mode.

Advisory Ice Detection System is an advisory system annunciates the presence of icing conditions or ice accretion. The advisory ice detection system provides information advising the flightcrew of the presence of ice accretion or icing conditions. It can only be used in conjunction with other means (most commonly, visual observation by the flightcrew) to determine [...]

The title given to equations, developed by L. Euler, for calculating the flow of a frictionless, nonviscous fluid. The equations address compressibility of a fluid. They do not address flowfield discontinuities, such as those from shocks. Flow field rotation can be computed. The Euler equations of fluid flow can be integrated throughout a finite region [...]

Collateral Icing is ice accretions that occur on aircraft surfaces other than those typically considered when aircraft certification tests use simulated ice shapes. Examples are ice feathers that accumulate on fuselage, nacelle, nacelle pylons, empennage, antennas, and wing surfaces.
