Aircraft Inflight Ice Detectors and Icing Rate Measuring Instruments

2018-06-11
WIP
AIR4367B
This document provides information regarding ice detector technology, design and operating requirements. The SAE document AS5498 provides detailed information regarding the requirements, specifications, qualification, and certification of icing detection systems. This document is not meant to replace AS5498 but to enhance it by considering unique aspects of sensing technology and in particular those that may not be certificated at the time of this revision. To that end an effort has been made not to duplicate information contained in AS5498. Icing rate information is included where applicable. The primary application is associated with ice forming on the leading edges of airfoils and inlets while the aircraft is in flight. Information related to detection of ice over cold fuel tanks and icing at low velocity operation is included. The material is primarily applicable to fixed-wing aircraft. Unique requirements for engine inlets and rotorcraft are also provided.

Ice Crystal and Mixed Phase Icing Tunnel Testing of Air Data Probes

2018-04-16
WIP
AIR6974
This document provides information on current practices for testing air data probes to 14 CFR Part 33 Appendix D ice crystal and mixed phase icing conditions. This AIR is primarily concerned with techniques for measuring the flow and icing environment in the test facility. While the focus of this report is the testing of air data probes, techniques described may be applicable to Appendix D tests of other aerospace equipment as well.

Ice Protection for Unmanned Aerial Vehicles

2017-09-22
WIP
AIR6962
A review of icing materials that would be educational to a designer of a UAV ice protection system is provided. Additionally, the differences between unmanned and manned ice protection systems are explored along with a discussion on how these differences can be addressed.

SLD capabilities of icing wind tunnels

2015-07-09
WIP
AIR6341
The purpose of this AIR is to compile in one definitive source, commonly accepted calibration, acceptance criteria and procedures for simulation of Supercooled Large Droplet (SLD) conditions within icing wind tunnels. Facilities that meet the criteria for either some or all of the recognized conditions will have known SLD icing simulation capability.

Guidance on Selecting a Ground-based Icing Simulation Facility

2013-04-24
WIP
AIR6247
This document is intended to serve two purposes: (1) provide a list of topics for potential customers to ask of the facility to aid their selection decision-making, and (2) provide a list of icing wind tunnel and engine test stand facilities that simulate flight through icing or ice crystal clouds.
