Which statement correctly describes the SFL runway requirements when considering CFI presence?

• A. With a CFI on board, 3000 Feet; Without a CFI on board, 5000 Feet
• B. With a CFI on board, 5000 Feet; Without a CFI on board, 3000 Feet
• C. Both cases require 3000 Feet
• D. Both cases require 5000 Feet

Answer: (A)

The key idea is that runway length requirements for student flight operations depend on whether a certified flight instructor is onboard. When a CFI is on board, the minimum acceptable runway length is shorter—3000 feet—because the instructor can provide immediate guidance, correct errors, and take over if needed, reducing the risk during takeoff and landing. Without a CFI, there’s no supervising pilot ready to intervene, so more runway is required to provide a larger safety margin for potential go-arounds, aborts, or student mistakes; hence the 5000-foot minimum. In practice, you must choose a field that meets the applicable minimums for the current operation and also consider other factors like aircraft performance, weight, density altitude, wind, terrain, and obstacles.
