A remote pilot reviews the following METAR before a 1 PM shoot: KXYZ 151755Z 09006KT 6SM SCT020 BKN035 24/17 A3001. The planned altitude is 250 feet AGL. Can the pilot legally conduct the operation under standard Part 107 cloud clearance and visibility rules?

AYes; visibility and cloud clearance are both within Part 107 minimums
BNo; the broken layer at 3,500 feet prevents legal operation at 250 feet AGL
CNo; 6 SM visibility does not meet the Part 107 minimum

Why →Under § 107.51(c) and (d), minimum visibility is 3 statute miles from the control station and minimum cloud clearance is 500 feet below and 2,000 feet horizontal from clouds. Visibility of 6 SM exceeds the minimum. The scattered layer at 2,000 feet AGL is 1,750 feet above the planned altitude, well above the 500-foot below-clouds requirement. The operation is legal.

The trap →The option citing the broken layer at 3,500 feet confuses ceiling rules (manned aviation) with the drone cloud-clearance rule. The option claiming 6 SM does not meet the minimum misremembers the 3 SM Part 107 minimum as a higher number. The correct analysis requires applying each rule to each reported value.

Field note →Decode METAR cloud layers in AGL relative to the reporting station. SCT020 means scattered at 2,000 feet AGL. Your 500-below clearance is measured from the lowest cloud base at your operating area.
