What altitude should an aircraft reach while upwind of the duty runway at Spencer?

• A. 200 MSL
• B. 210 MSL
• C. 180 MSL
• D. 200 AGL

Answer: (A)

The correct altitude for an aircraft while upwind of the duty runway at Spencer is 200 MSL (Mean Sea Level). This altitude is commonly designated to ensure safe separation from ground obstacles and to maintain appropriate airspace management in the vicinity of the airfield.

By maintaining 200 MSL, pilots are granted a buffer zone that accommodates potential variations in terrain height and ensures compliance with prescribed regulations for safe vertical separation. This altitude is part of standard operating procedures and aligns with local operational guidelines to ensure that aircraft are safely positioned upwind and adequately cleared from the runway approach path.

While other altitudes may seem reasonable, they might not provide the same level of safety and adherence to local air traffic control protocols. For instance, choosing an altitude that is lower could risk conflicts with buildings or natural terrain features, while opting for 210 MSL may exceed necessary clearance margins, leading to inefficient use of airspace. Thus, 200 MSL is established as the optimal standard for aircraft in this particular airspace scenario at Spencer.
