Narrative:

This is not a report of an incident. It is a suggestion about how to reduce altdevs. Have controllers issue vectors in headings which end in a 5 (or any digit other than 0, whenever possible) instead of today's common practice of most vectors ending in a zero. This would help eliminate the confusion between flight levels and headings. For example: today's clearance to FL270 and a heading of 250 is confusion looking for a place to happen. Under my suggestion, the clearance would be to FL270 and a heading of either 245 degrees, 255 degrees, 249 degrees, or 251 degrees. Much less potential for confusion and error. Several pilots I have talked with liked the idea and the FAA poi for a freighter line suggested I send this to you.

Title: ACR PLT SUGGESTS ATC PHRASEOLOGY CHANGE AND PLT CTLR USAGE.

Narrative: THIS IS NOT A RPT OF AN INCIDENT. IT IS A SUGGESTION ABOUT HOW TO REDUCE ALTDEVS. HAVE CTLRS ISSUE VECTORS IN HDGS WHICH END IN A 5 (OR ANY DIGIT OTHER THAN 0, WHENEVER POSSIBLE) INSTEAD OF TODAY'S COMMON PRACTICE OF MOST VECTORS ENDING IN A ZERO. THIS WOULD HELP ELIMINATE THE CONFUSION BTWN FLT LEVELS AND HDGS. FOR EXAMPLE: TODAY'S CLRNC TO FL270 AND A HDG OF 250 IS CONFUSION LOOKING FOR A PLACE TO HAPPEN. UNDER MY SUGGESTION, THE CLRNC WOULD BE TO FL270 AND A HDG OF EITHER 245 DEGS, 255 DEGS, 249 DEGS, OR 251 DEGS. MUCH LESS POTENTIAL FOR CONFUSION AND ERROR. SEVERAL PLTS I HAVE TALKED WITH LIKED THE IDEA AND THE FAA POI FOR A FREIGHTER LINE SUGGESTED I SEND THIS TO YOU.
