The AN/CYZ-10 Data Transfer Device, often called a Filler, Crazy 10, ANCD or DTD, is a United States National Security Agency-developed, portable, hand-held fill device, for securely receiving, storing, and transferring data between compatible cryptographic and communications equipment. It is capable of storing 1,000 keys, maintains an automatic internal audit trail of all security-relevant events that can be uploaded to the LMD/KP, encrypts key for storage, and is programmable. The DTD is capable of keying multiple information systems security (INFOSEC) devices and is compatible with such COMSEC equipment as Single Channel Ground and Airborne Radio System (SINCGARS) radios, KY-57 VINSON, KG-84, and others that are keyed by common fill devices (CFDs). The AN/CYZ-10 supports both the DS-101 and DS-102 interfaces.
The DTD weighs about 4 lb (1.8 kg) and is designed to be fully compatible with future INFOSEC equipment meeting DS-101 signaling and benign fill standards. It will eventually replace the legacy family of CFDs, including the KYK-13, KYX-15 electronic storage devices, and the KOI-18 paper tape reader. Note that only the DTD and the KOI-18 support newer, 128-bit keys.
Cauayan Airport (Filipino: Paliparan ng Cauayan, Ilokano: Pagtayaban ti Cauayan) (IATA: CYZ, ICAO: RPUY) is an airport serving the general area of Cauayan, a city in Isabela province in the Philippines. It is one of three commercial airports in Isabela, the other being Palanan Airport in the town of Palanan and Maconacon Airport in the town of Maconacon. It is classified as a secondary airport, or a minor commercial domestic airport, by the Air Transportation Office, a body of the Department of Transportation and Communications that is responsible for the operations of not only this airport but also of all other airports in the Philippines except the major international airports.
Between 1999 and 2008, the airport hosted no commercial flights. Proposal were made to reintroduce commercial service the airport, such as an independent Manila-Cauayan route, as well as a route further on to Tuguegarao Airport in Tuguegarao. After almost a decade of not hosting commercial service, Cauayan Airport re-opened to commercial traffic on August 15, 2008 using PAL Express aircraft, marking the return of Philippine Airlines to Cauayan, having stopped its services to the city in 1994. At present, Cebu Pacific uses Airbus A319/A320 for its Manila-Cauayan-Manila route.
