Human factors certification criteria are being developed for large civil aircraft to replace the interim policies currently in place for this purpose. The objective of these initiatives is to reduce the incidence of design induced error. Many formal error identification and prediction techniques currently exist, however none of these have been validated for their use in an aviation context due to a lack of validation data. Accident and incident reports do not contain sufficient detail in this respect. This paper describes a survey of commercial pilots to collect data on common, design induced errors on modern flight deck during the approach and landing phases of flight. These data will subsequently be used in the validation of a formal error prediction technique for use on the flight deck.
