No more waiting for Temporary Revision (TR) updates. With the MHIRJ Flight Deck* application, MHIRJ aircraft pilots can enjoy the benefits of going paperless¹ by being able to store and access manual data and other documentation instantly from their iPad® - without Wi-Fi. No other solution combines automatic TR updates, user control of content and aircraft serial number-specific information into one application. MHIRJ Flight Deck* generates FAA, EASA and TC compliant audit trails for paperless¹ operations to prove your flight manuals are up-to-date. FAST AND EASY In addition to being able to access MHIRJ flight manual subscriptions, you can control all of your electronic documentation in one place. Fleet managers, dispatchers and other members of your team can drag and drop electronic versions of aircraft documents, manuals and forms into online folders. Pilots simply enter a license code, then push a sync button on the iPad® and all updated documents (and subscribed documents) are automatically downloaded and cataloged. In less time than it takes to send a fax, pilots can sign documents, add text and email it to the fleet manager. AUTOMATIC REVISION UPDATES No more manually inserting revisions or Temporary Revisions (TRs) into MHIRJ’s flight manuals. These are automatically inserted into the correct sections and distributed across every iPad® in the operator’s fleet by MHIRJ Technical Publications. Valuable time is saved and pilots are always ready to fly in accordance with the latest regulatory requirements. Powered by OBDS XR (r) technology, for reliability, security and speed. ¹ Paperless refers to the process identified in the relevant airworthiness requirement pertaining to paperless cockpits, including but not limited to FAA-AC-91-78,and AC-120-76D Use of the MHIRJ Flight Deck* application does not relieve operator and its flight crew of their responsibility to comply with the applicable airworthiness authority approved documents.
