The most effective method of scanning for other aircraft for collision avoidance during nighttime hours is to use

During operations outside controlled airspace at altitudes of more than 1,200 feet AGL, but less than 10,000 feet MSL, the minimum flight visibility for VFR flight at night is

During operations within controlled airspace at altitudes of less than 1,200 feet AGL, the minimum horizontal distance from clouds requirement for VFR flight is

(Refer to figure 21, area 4.) What hazards to aircraft may exist in restricted areas such as R-5302B?
