Narrative:

Attempting to back taxi for takeoff at a small uncontrolled field. Ramp 350 ft of taxiway to runway thence some 4000 ft to departure end. Steady stream of inbounds for safety meeting (!). Between third and fourth aircraft in sequence, taxied down taxiway, tried to dos-a-dos with aircraft exiting, advised on radio (unicom 122.8) but not listening. Delayed onto runway to back taxi, saw aircraft on downwind (midfield) called back taxi, asked aircraft to extend downwind, high speed taxi toward approach end. Tight 180 degrees turn in by landing aircraft. Landing caught me 2/3 of way down. Pulled off as far as snow banks permitted, and other aircraft landed on right side of runway. Pulled down to run-up pad (off runway) ahead of small aircraft Z. On final (no conflict). During entire time, none of 3 aircraft answered my calls. Of 6 who landed, 1 called 'downwind,' 1 reported 'clear of active' -- no other radio calls made or heard. Lessons: 1) don't be impatient to depart. 2) always self announce and monitor CTAF at uncontrolled fields: not everyone was born there!

Title: NEAR CRITICAL CONFLICT ON GND WITH DEP AND ARR TFC AT A NON TWR ARPT UNICOM.

Narrative: ATTEMPTING TO BACK TAXI FOR TKOF AT A SMALL UNCTLED FIELD. RAMP 350 FT OF TAXIWAY TO RWY THENCE SOME 4000 FT TO DEP END. STEADY STREAM OF INBOUNDS FOR SAFETY MEETING (!). BTWN THIRD AND FOURTH ACFT IN SEQUENCE, TAXIED DOWN TAXIWAY, TRIED TO DOS-A-DOS WITH ACFT EXITING, ADVISED ON RADIO (UNICOM 122.8) BUT NOT LISTENING. DELAYED ONTO RWY TO BACK TAXI, SAW ACFT ON DOWNWIND (MIDFIELD) CALLED BACK TAXI, ASKED ACFT TO EXTEND DOWNWIND, HIGH SPD TAXI TOWARD APCH END. TIGHT 180 DEGS TURN IN BY LNDG ACFT. LNDG CAUGHT ME 2/3 OF WAY DOWN. PULLED OFF AS FAR AS SNOW BANKS PERMITTED, AND OTHER ACFT LANDED ON R SIDE OF RWY. PULLED DOWN TO RUN-UP PAD (OFF RWY) AHEAD OF SMA Z. ON FINAL (NO CONFLICT). DURING ENTIRE TIME, NONE OF 3 ACFT ANSWERED MY CALLS. OF 6 WHO LANDED, 1 CALLED 'DOWNWIND,' 1 RPTED 'CLR OF ACTIVE' -- NO OTHER RADIO CALLS MADE OR HEARD. LESSONS: 1) DON'T BE IMPATIENT TO DEPART. 2) ALWAYS SELF ANNOUNCE AND MONITOR CTAF AT UNCTLED FIELDS: NOT EVERYONE WAS BORN THERE!
