Narrative:

When pwring back from gte to ramp, we called ground for clearance (to power back). He (ground control) said it was our discretion to do so. When taxiing out, ground control informed us that ramp control wanted to talk to us. When we called ramp (131.37) he said that we should have gotten a clearance from him (ramp control) to power back. After reviewing our 10-7 page we noted that it did say to call ramp control for power back on one page. On another, it said to call for taxi. Quite confusing.

Original NASA ASRS Text

Title: MLG PWRS BACK WITHOUT RAMP CLRNC.

Narrative: WHEN PWRING BACK FROM GTE TO RAMP, WE CALLED GND FOR CLRNC (TO PWR BACK). HE (GND CTL) SAID IT WAS OUR DISCRETION TO DO SO. WHEN TAXIING OUT, GND CTL INFORMED US THAT RAMP CTL WANTED TO TALK TO US. WHEN WE CALLED RAMP (131.37) HE SAID THAT WE SHOULD HAVE GOTTEN A CLRNC FROM HIM (RAMP CTL) TO PWR BACK. AFTER REVIEWING OUR 10-7 PAGE WE NOTED THAT IT DID SAY TO CALL RAMP CTL FOR PWR BACK ON ONE PAGE. ON ANOTHER, IT SAID TO CALL FOR TAXI. QUITE CONFUSING.
