What PEC adjustment is specified for the Seneca V's decision altitude?

• A. Subtract 50 ft
• B. No adjustment
• C. Add 100 ft
• D. Add 50 ft to decision altitude

Answer: (D)

When performing a precision approach with consideration for an engine-out condition, you apply a PEC (Pilot Experience Correction) to the decision altitude to reflect the airplane’s degraded single-engine performance. The Seneca V specifies a PEC adjustment of plus 50 ft to the decision altitude, meaning you increase the DA by 50 ft to maintain the required obstacle clearance if one engine is inoperative. This modest increase accounts for reduced climb capability, asymmetric thrust effects, and overall slower handling during the approach and go-around phase. Not applying any adjustment would underestimate the margin needed with an engine out, and larger adjustments (like 100 ft) would go beyond the published guidance. So, the correct approach is to add 50 ft to the decision altitude.
