This laser is also the designator for the AGM-114 Hellfire that are carried on the MQ-1. Deployment methodology Each Predator air vehicle can be disassembled into six modules and loaded into a container nicknamed "the coffin". This enables all system components and support equipment to be rapidly deployed worldwide. The largest component is the ground control station (GCS) which is designed to roll into a C-130 Hercules. The Predator primary satellite link consists of a 6.1-meter (20-ft) satellite dish with associated support equipment. The satellite link provides communications between the GCS and the aircraft when it is beyond line-of-sight and links to networks that disseminate secondary intelligence. The RQ-1A system needs 1,500 by 40 meters (5,000 by 125 ft) of hard surface runway with clear line-of-sight to each end from the GCS to the air vehicles. Initially, all components needed to be located on the same airfield. , the U.S. Air Force used a concept called "Remote-Split Operations" where the satellite datalink is placed in a different location and is connected to the GCS through fiber optic cabling. This allows Predators to be launched and recovered by a small "Launch and Recovery Element" and then handed off to a "Mission Control Element" for the rest of the flight. This allows a smaller number of troops to be deployed to a forward location, and consolidates control of the different flights in one location. The improvements in the MQ-1B production version include an ARC-210 radio, an APX-100 IFF/SIF with mode 4, a glycol-weeping "wet wings" de-icing system, upgraded turbo-charged engine, fuel injection, longer wings, dual alternators as well as other improvements. On 18 May 2006, the Federal Aviation Administration (FAA) issued a certificate of authorization which will allow the M/RQ-1 and M/RQ-9 aircraft to be used within U.S. civilian airspace to search for survivors of disasters. Requests had been made in 2005 for the aircraft to be used in search and rescue operations following Hurricane Katrina, but because there was no FAA authorization in place at the time, the assets were not used. The Predator's infrared camera with digitally enhanced zoom has the capability of identifying the infrared signature of a human body from an altitude of 3 km (10,000 ft), making the aircraft an ideal search and rescue tool. The longest declassified Predator flight lasted for 40 hours, 5 minutes. The total flight time reached 1 million hours in April 2010,
