Narrative:

During a routine x-country training mission I noticed that the fuel quantity was lower than I had planned for. I instructed my student to return as quickly as possible to sdl. Within 1 mi of the airport we noticed the fuel low warning light flickering. I elected to make a precautionary landing rather than risk an engine failure. I reported to the tower that I was making a precautionary landing for fuel. After a normal approach and landing, fuel was brought out to me and I continued flight to the airport. I calculated fuel burn at 9.6 gph after the incident. This was 1.6 gph higher consumption than I have ever recorded. Nowhere in the helicopter operator's manual are there any performance guidelines or charts for fuel consumption, and therefore I relied upon my experience with previous x-countries to estimate fuel burn on this occasion. I made a poor decision not to stop at an airport 10 mi from sdl and have my employer come out and pay for filling the aircraft. I think that it would help pilots of type a helicopter's if the operator's manual contained some type of fuel burn chart.

Title: LIGHT HELICOPTER LOW ON FUEL JUST SHORT OF DESTINATION ELECTS PRECAUTIONARY LNDG.

Narrative: DURING A ROUTINE X-COUNTRY TRNING MISSION I NOTICED THAT THE FUEL QUANTITY WAS LOWER THAN I HAD PLANNED FOR. I INSTRUCTED MY STUDENT TO RETURN AS QUICKLY AS POSSIBLE TO SDL. WITHIN 1 MI OF THE ARPT WE NOTICED THE FUEL LOW WARNING LIGHT FLICKERING. I ELECTED TO MAKE A PRECAUTIONARY LNDG RATHER THAN RISK AN ENG FAILURE. I RPTED TO THE TWR THAT I WAS MAKING A PRECAUTIONARY LNDG FOR FUEL. AFTER A NORMAL APCH AND LNDG, FUEL WAS BROUGHT OUT TO ME AND I CONTINUED FLT TO THE ARPT. I CALCULATED FUEL BURN AT 9.6 GPH AFTER THE INCIDENT. THIS WAS 1.6 GPH HIGHER CONSUMPTION THAN I HAVE EVER RECORDED. NOWHERE IN THE HELI OPERATOR'S MANUAL ARE THERE ANY PERFORMANCE GUIDELINES OR CHARTS FOR FUEL CONSUMPTION, AND THEREFORE I RELIED UPON MY EXPERIENCE WITH PREVIOUS X-COUNTRIES TO ESTIMATE FUEL BURN ON THIS OCCASION. I MADE A POOR DECISION NOT TO STOP AT AN ARPT 10 MI FROM SDL AND HAVE MY EMPLOYER COME OUT AND PAY FOR FILLING THE ACFT. I THINK THAT IT WOULD HELP PLTS OF TYPE A HELI'S IF THE OPERATOR'S MANUAL CONTAINED SOME TYPE OF FUEL BURN CHART.
