SMA TAXIING AT UNCTLED ARPT XING RWY TO GET TO FAVORED RWY HAS CONFLICT WITH LNDG ACFT.

Narrative

AFTER RECEIVING OUR IFR CLRNC TO RENO FROM THE REDMOND FSS; I ASKED FOR ADVISORIES AND WAS TOLD THAT THE WINDS WERE 330 AT 11; AND THAT RWYS 28 AND 4 WERE FAVORED. I THEN ANNOUNCED ON THE CTAF MY INTENTION TO TAXI TO RWY 4; WHICH INVOLVES XING RWY 10/28. WHEN WE ARRIVED AT 10/28; I AND THE 3 OF MY 4 PAXS WHO HAD ACCESS TO WINDOWS LOOKED BOTH WAY FOR TFC; THEN PROCEEDED TO CROSS THE RWY. WHEN WE WERE HALFWAY ACROSS; ONE OF MY PAX EXCLAIMED SOMETHING OR OTHER; AND POINTED TO OUR R (TOWARD THE APCH END OF RWY 10). INDEED; A SMA (WHITE WITH BLUE STRIPES) HAD JUST LANDED AND WAS ROLLING OUT IN OUR DIRECTION. THE SMA HAD; IN FACT; VEERED TO IT'S L AND MISSED US BY ABOUT 500 FT (IE; IT WASN'T THAT CLOSE; THOUGH IT WAS AWFULLY DISCONCERTING). HERE ARE THE IMPORTANT SAFETY CONSIDERATIONS FROM MY PERSPECTIVE: 1) THE SMA DID NOT CALL IN HIS INTENTIONS; NEITHER I NOR ANY OF MY PAXS RECALL HEARING ANY CALL-IN ON THE CTAF (WHICH WE WERE MONITORING FROM THE MOMENT OF ENG START). SINCE HE LANDED WITH AN 11 KT TAILWIND; I ASSUME THAT HE EITHER DIDN'T CALL FOR ADVISORIES FROM THE AAS OR HE DIDN'T MUCH CARE. SINCE IT WAS AT LEAST 5 MINS FROM THE TIME I STARTED MY ENG UNTIL THE TIME OF THE INCIDENT; MY SUSPICION IS THAT HE NEVER CALLED. AS AN ASIDE; THE PLT IS BASED IN REDMOND; SO HE KNOWS THE ARPT EXTREMELY WELL. MY GUESS IS THAT WELL-KNOWN; HIGH-TIME LCL PLTS TAKE AN AWFUL LOT FOR GRANTED. 2) ALTHOUGH THE 'SEE AND AVOID' CONCEPT IS WONDERFUL IN THE IDEAL; IT DOESN'T PROVIDE NEARLY THE SAFETY FACTOR OF 'SEE AND AVOID' PLUS USING RADIOS. 4 OF US LOOKED IN THE DIRECTION OF THE LNDG PLANE; YET NONE OF US SAW HIM AT THE TIME WE CHKED; HE WAS PROBABLY JUST A FEW FT OFF THE GND -- VERY DIFFICULT TO MAKE OUT AGAINST A HAZY SKY; TREES; ETC IN THE BACKGND. IT IS NATURAL TO LOOK 'HARDER' IN THE DIRECTION YOU ARE EXPECTING TO SEE SOMETHING; SO I WOULDN'T RULE OUT THE IDEA THAT WE ALL LOOKED AT RWY 28 (IE; THE PREFERRED RWY) A LOT HARDER THAN AT RWY 10. 3) I DON'T UNDERSTAND WHY THE FAR'S DON'T REQUIRE THAT PLANES LNDG AT UNCTLED FIELDS USE THEIR RADIOS IF THEY HAVE THEM. ADDED TO THE RWY BEHIND YOU; THE SKY ABOVE YOU; AND THE FUEL L BEHIND (OR WHATEVER THE 3 MOST USELESS THINGS ARE SUPPOSED TO BE); I WOULD ADD A FOURTH: THE RADIO YOU DON'T USE. THERE IS NO QUESTION THAT PLTS SHOULD USE EVERY MEANS AT THEIR DISPOSAL TO ENHANCE THE SAFETY OF THEIR FLT. I CAN'T SEE ANY EXCUSE FOR THE OTHER PLT NOT TO HAVE COMMUNICATED. 4) REDMOND ARPT IS AN ACCIDENT WAITING TO HAPPEN. BTWN RECREATION; BUSINESS; COMMERCIAL FLTS; AND FOREST SVC OPS; REDMOND IS AN EXTREMELY BUSY ARPT. ADD TO THIS THE FACT THAT THERE AREN'T EVEN ANY TAXIWAYS TO RWY 28; AND YOU'VE GOT THE POTENTIAL FOR DISASTER. I HAVE HEARD FROM MANY PLTS THAT THEY CONSIDER REDMOND ONE OF THE MOST DANGEROUS ARPTS IN THE NW.
