Final answer:
The VFR weather minimums for takeoff depend on the airspace around the airport. A general rule for uncontrolled airspace is 1 statute mile visibility and clear of clouds during the day. Controlled airspace typically requires 3 statute miles of visibility and specific cloud clearance distances.
Step-by-step explanation:
The VFR weather minimums required to take off from an airport, such as Salina Airport, depend on several factors including the airspace class in which the airport is located. For most uncontrolled airports, which typically fall under Class G airspace, the minimum visibility requirement for VFR flight below 10,000 feet is 1 statute mile during the day and 3 statute miles at night. Pilots must also remain clear of clouds. However, for controlled airspaces, such as Class D airspace which may be associated with some busier airports, the VFR weather minimums are typically 3 statute miles visibility and cloud clearance of 500 feet below, 1,000 feet above, and 2,000 feet horizontal distance from clouds. Therefore, options 1) and 3) could potentially be correct depending on the airspace, while option 2) does not meet the standard VFR weather minimums. Option 4) exceeds standard minimums and might apply to certain special VFR conditions. Always check actual airport and airspace weather minimum requirements before planning a flight.
