Final answer:
The correct takeoff wake separation in a non-radar environment is 3 minutes, which is the standard time required to avoid the risks associated with wake turbulence from the preceding aircraft.
Step-by-step explanation:
The question pertains to the required takeoff wake separation in a non-radar environment for aircraft. This separation is a measure used to avoid the potential hazards of wake turbulence, which is a byproduct of the lift generated by the wings of an aircraft. Wake turbulence can persist in the air for several minutes after an aircraft has passed and can impose a significant risk to following aircraft, particularly during takeoff and landing phases.
The correct answer to the question is option B) 3 minutes. This is the minimum time separation required for aircraft operating in a non-radar environment, where air traffic controllers cannot use radar to judge the distance between aircraft for safe separation. Instead, they use standard time intervals to ensure that the wake turbulence from the leading aircraft has dissipated enough for the following aircraft to safely take off
