Final answer:
The minimum taxi strip for a 180° turn with a 3-ft margin of safety is 12 ft.
Step-by-step explanation:
The minimum taxi strip for a 180° turn with a 3-ft margin of safety can be calculated using the formula:
Taxi Strip = 2 × R × tan(θ/2) + 2 × M
Where R is the radius of the turn, θ is the angle of the turn in radians, and M is the margin of safety.
In this case, since the turn is 180°, or π radians, and the margin of safety is 3 ft, the formula becomes:
Taxi Strip = 2 × R × tan(π/2) + 2 × 3 ft
Since tan(π/2) is undefined, the taxi strip is simply 6 ft + 2 × 3 ft = 12 ft.
