What is the base and tops of the overcast layer reported by a pilot?

When a pilot reports the base and tops of an overcast layer, they provide the altitudes at which the cloud layer begins and ends, measured in feet above mean sea level (MSL). The correct answer indicates that the base of the overcast layer is at 7,200 feet MSL and the top is at 8,900 feet MSL. This means that the cloud layer extends between these altitudes, giving a clear understanding of the vertical extent of the overcast conditions.

In aviation, knowing the altitude of cloud layers is crucial for flight planning, particularly regarding visual flight rules (VFR) and instrument flight rules (IFR). To maintain safe navigation, pilots need to ensure they are flying above the clouds or understand the implications of flying through such conditions. The specified altitudes help pilots assess their flight path in relation to the weather conditions.

The other options do not accurately represent a standard range for an overcast layer or include incorrect altitude measurements that do not align with typical reports. Therefore, option C provides a logical and factual account of the overcast layer's base and tops, which is essential for pilots when making decisions about their flight operations.
