Pilot of a aerospatiale AS350BA could not hover during the helicopter transition departure procedure from phx airport due to the high ambient temperature reducing aircraft performance resulting in the pilot not being able to change to the other tower frequency until landing.

Narrative:
During departure from phx, we were very heavy and the ambient temperature was very high. To adhere to helicopter procedures we were unable to hover and had to land during transition between the north and south runway. As a result we were unable to switch tower's frequency until we landed. I believe this caused the tower to feel we were going to violate the runway boundaries. We did not violate the crossing, but we could not call for the second crossing until we were settled on the ground. We think that these procedures should be modified to allow a little more latitude in sits where an aircraft's performance becomes an issue.

Title: PLT OF A AEROSPATIALE AS350BA COULD NOT HOVER DURING THE HELI TRANSITION DEP PROC FROM PHX ARPT DUE TO THE HIGH AMBIENT TEMP REDUCING ACFT PERFORMANCE RESULTING IN THE PLT NOT BEING ABLE TO CHANGE TO THE OTHER TWR FREQ UNTIL LNDG.
Narrative: DURING DEP FROM PHX, WE WERE VERY HVY AND THE AMBIENT TEMP WAS VERY HIGH. TO ADHERE TO HELI PROCS WE WERE UNABLE TO HOVER AND HAD TO LAND DURING TRANSITION BTWN THE N AND S RWY. AS A RESULT WE WERE UNABLE TO SWITCH TWR'S FREQ UNTIL WE LANDED. I BELIEVE THIS CAUSED THE TWR TO FEEL WE WERE GOING TO VIOLATE THE RWY BOUNDARIES. WE DID NOT VIOLATE THE XING, BUT WE COULD NOT CALL FOR THE SECOND XING UNTIL WE WERE SETTLED ON THE GND. WE THINK THAT THESE PROCS SHOULD BE MODIFIED TO ALLOW A LITTLE MORE LATITUDE IN SITS WHERE AN ACFT'S PERFORMANCE BECOMES AN ISSUE.
