42. IMAC Judging Seminar Judging Criteria Scale Aerobatics Judging SeminarJ-41  No Aerobatics prior to entering the Aerobatic Airspace.

(Contest Jury, CD, etc.) Procedural Items 01/30/2010

43. IMAC Judging Seminar J-42Scale Aerobatics Judging Seminar Must prepare – review / know the sequence. Have a scribe – the seq. is probably unusual to you & you shouldn’t look away to write scores. If in Adv or Unlit’d. a knowledgeable scribe can call the Aresti for you – again, avoid looking away from aircraft. If judging above “your” class, guard against the halo bias. Don’t judge higher than your current judging capabilities. End of Judging Criteria Module Judging Criteria 01/30/2010
