Developed specifically to address the new FAA aircraft certification regulations, SLD Guard protects against the threat of supercooled large drops (SLD).
Whilst less common than standard small droplet icing, SLD icing can occur treacherously fast due to the larger size of SLD drops (more than 0.05mm). Freezing only partially on contact, the drop is swept back by the airflow until it is fully frozen in a layer of clear ice, impacting a greater area of the aircraft’s surfaces.
An anti-ice and de-ice protection system, SLD Guard is designed to handle rapid ice accumulation on aircraft wings at critical flight controls. It is certified for Flight Into Known Icing and allows aircraft to safely withstand unexpected icing encounters of freezing rain and drizzle as defined by Appendix O of the Federal Aviation Regulations.
SLD Guard now permits new aircraft that require certification, to be certified for continuous operation in both the entire Appendix C and Appendix O envelopes.

As a new factory f it option, it can be installed alongside any current primary ice protection selected by the manufacturer and as the system is inset into the original design of the frame, it does not impact aircraft performance.
LikeTKS®, SLD Cuard is a freezing point dépréssion system and is installed in the form of titanium strips on the upper wing surfaces ahead of the ailerons, as well as the upper and lower surfaces of the horizontal stabilizer.
