Narrative:
This report is offered for the ASRS and NASA study of fans datalink. Advantages: 1) clear, concise instructions, if standardized ATC procedures are followed, compared to difficulties in understanding non native english speaking controllers. 2) hard copy printout of ATC clearance for reference and record keeping. 3) direct ATC communication faster and more error free than relaying through a 3RD party such as commercial radio or other radio service. Fans datalink operational difficulties are: 1) conditional clrncs specifying altitude changes at a future time and/or fix. 2) non standard delivery (wording) of clearance from oceanic ATC's. 3) lack of printing capability of ATC clearance when using center CDU and commercial radio. Suggestions: 1) standardize fans ATC clrncs throughout oceanic ATC. 2) prohibit ATC from using conditional clrncs, eg, altitude changes at specified time and/or fix crossing. 3) if #2 not possible, require crew to accept (if crew accepts) clearance by sending a free text message to ATC with a 'wilco' response and 'repeat' of the clearance, eg, 'flight XXX wilco to climb and maintain FL330 after crossing XXX fix.'

Title: A CAPT WRITES OF RPT TO SUMMARIZE WHAT HE LIKES AND DOESN'T LIKE ABOUT FANS PROCS WHEN FLYING THE SOUTH PACIFIC.
Narrative: THIS RPT IS OFFERED FOR THE ASRS AND NASA STUDY OF FANS DATALINK. ADVANTAGES: 1) CLR, CONCISE INSTRUCTIONS, IF STANDARDIZED ATC PROCS ARE FOLLOWED, COMPARED TO DIFFICULTIES IN UNDERSTANDING NON NATIVE ENGLISH SPEAKING CTLRS. 2) HARD COPY PRINTOUT OF ATC CLRNC FOR REF AND RECORD KEEPING. 3) DIRECT ATC COM FASTER AND MORE ERROR FREE THAN RELAYING THROUGH A 3RD PARTY SUCH AS COMMERCIAL RADIO OR OTHER RADIO SVC. FANS DATALINK OPERATIONAL DIFFICULTIES ARE: 1) CONDITIONAL CLRNCS SPECIFYING ALT CHANGES AT A FUTURE TIME AND/OR FIX. 2) NON STANDARD DELIVERY (WORDING) OF CLRNC FROM OCEANIC ATC'S. 3) LACK OF PRINTING CAPABILITY OF ATC CLRNC WHEN USING CTR CDU AND COMMERCIAL RADIO. SUGGESTIONS: 1) STANDARDIZE FANS ATC CLRNCS THROUGHOUT OCEANIC ATC. 2) PROHIBIT ATC FROM USING CONDITIONAL CLRNCS, EG, ALT CHANGES AT SPECIFIED TIME AND/OR FIX XING. 3) IF #2 NOT POSSIBLE, REQUIRE CREW TO ACCEPT (IF CREW ACCEPTS) CLRNC BY SENDING A FREE TEXT MESSAGE TO ATC WITH A 'WILCO' RESPONSE AND 'REPEAT' OF THE CLRNC, EG, 'FLT XXX WILCO TO CLB AND MAINTAIN FL330 AFTER XING XXX FIX.'
