After departing sac exec, runway 20, started right turn to 230 degrees (tower open). Got release from tower to talk to travis approach, as flight would take us through their airspace. After contact and radar identify, asked for 3000' MSL en route altitude, or whatever they would like us at for traffic, flight following radar traffic sep service. After about 5 mins they requested we either climb to 5500' or depart the area to the west because of 8 or 9 heavy's in the travis pattern. We said we'd like to climb to 5500' and fly direct to apc. We shortly thereafter contacted the controller again to confirm 5500' because of the hemispherical rule and he confirmed 5500'. We climbed to 5500' as per instructions and continued at this altitude for about 15 mins before being released to descend toward napa airport. Our concern is that even though we were instructed to fly at 5500' by ATC, we were not obligated to even contact approach or tower because we were above their air traffic area.
Original NASA ASRS Text
Title: GA SMA QUESTIONS LEGALITY OF MIL CTLR ASSIGNING ALT NOT IN ACCORDANCE WITH HEADING ALT RULE WHILE TRANSITING A MIL ALERT AREA.
Narrative: AFTER DEPARTING SAC EXEC, RWY 20, STARTED RIGHT TURN TO 230 DEGS (TWR OPEN). GOT RELEASE FROM TWR TO TALK TO TRAVIS APCH, AS FLT WOULD TAKE US THROUGH THEIR AIRSPACE. AFTER CONTACT AND RADAR IDENT, ASKED FOR 3000' MSL ENRTE ALT, OR WHATEVER THEY WOULD LIKE US AT FOR TFC, FLT FOLLOWING RADAR TFC SEP SVC. AFTER ABOUT 5 MINS THEY REQUESTED WE EITHER CLB TO 5500' OR DEPART THE AREA TO THE W BECAUSE OF 8 OR 9 HVY'S IN THE TRAVIS PATTERN. WE SAID WE'D LIKE TO CLB TO 5500' AND FLY DIRECT TO APC. WE SHORTLY THEREAFTER CONTACTED THE CTLR AGAIN TO CONFIRM 5500' BECAUSE OF THE HEMISPHERICAL RULE AND HE CONFIRMED 5500'. WE CLBED TO 5500' AS PER INSTRUCTIONS AND CONTINUED AT THIS ALT FOR ABOUT 15 MINS BEFORE BEING RELEASED TO DSND TOWARD NAPA ARPT. OUR CONCERN IS THAT EVEN THOUGH WE WERE INSTRUCTED TO FLY AT 5500' BY ATC, WE WERE NOT OBLIGATED TO EVEN CONTACT APCH OR TWR BECAUSE WE WERE ABOVE THEIR ATA.
