Summary of career
Aerial victory claims
According to Spick, Woidich was credited with 110 aerial victories claimed in approximately 1,000 combat missions. Matthews and Foreman, authors of Luftwaffe Aces — Biographies and Victory Claims, researched the German Federal Archives and found records for 82 aerial victory claims, plus thirty further unconfirmed claims. This figure of confirmed claims includes 78 aerial victories on the Eastern Front and three on the Western Front, including one four-engined bomber flying the Me 163 rocket fighter. Victory claims were logged to a map-reference, for example "PQ 82191". The Luftwaffe grid map covered all of Europe, western Russia and North Africa and was composed of rectangles measuring 15 minutes of latitude by 30 minutes of longitude, an area of about. These sectors were then subdivided into 36 smaller units to give a location area 3 × 4 km in size.
