Narrative:
VFR departure from oakland. Ground advised experimental procedure for VFR departures as follows: 'clearance, turn right to 340 degree heading after takeoff. Climb to but remain below 2500'. Departure frequency XXXX squawk XXXX'. Normal takeoff! Runway 33. Immediately turned to 340 degree heading for climb out. Tower reported radar contact. I observed ceiling about 2100' MSL and hilltops obscured on 340 degree heading less than 4 mi ahead. I advised tower. I requested immediate climb (clearance) to 'on top'. Tower advised clearance unable. Suggested 30 degree right turn. (There was 300' or so clearance above hills on this heading, but deteriorating visibility, so I turned to about 010 degree. Tower then switched me to departure, where I repeated my request and was granted clearance. No further event occurred. A low time or student could have found themselves in IMC within three mins after takeoff. I do not believe this procedure advisable.

Title: PLT OF SMA ON VFR DEP FROM OAK WAS GIVEN HEADING AND ALT RESTRICTION NOT COMPATIBLE WITH WX AND TERRAIN, CHANGED TO DEP CTLR WHO GAVE VFR CLIMB TO ONTOP.
Narrative: VFR DEP FROM OAKLAND. GND ADVISED EXPERIMENTAL PROC FOR VFR DEPS AS FOLLOWS: 'CLRNC, TURN R TO 340 DEG HDG AFTER TKOF. CLB TO BUT REMAIN BELOW 2500'. DEP FREQ XXXX SQUAWK XXXX'. NORMAL TKOF! RWY 33. IMMEDIATELY TURNED TO 340 DEG HDG FOR CLBOUT. TWR RPTED RADAR CONTACT. I OBSERVED CEILING ABOUT 2100' MSL AND HILLTOPS OBSCURED ON 340 DEG HDG LESS THAN 4 MI AHEAD. I ADVISED TWR. I REQUESTED IMMEDIATE CLB (CLRNC) TO 'ON TOP'. TWR ADVISED CLRNC UNABLE. SUGGESTED 30 DEG R TURN. (THERE WAS 300' OR SO CLRNC ABOVE HILLS ON THIS HDG, BUT DETERIORATING VISIBILITY, SO I TURNED TO ABOUT 010 DEG. TWR THEN SWITCHED ME TO DEP, WHERE I REPEATED MY REQUEST AND WAS GRANTED CLRNC. NO FURTHER EVENT OCCURRED. A LOW TIME OR STUDENT COULD HAVE FOUND THEMSELVES IN IMC WITHIN THREE MINS AFTER TKOF. I DO NOT BELIEVE THIS PROC ADVISABLE.
