Narrative:

Weather on departure was 1/4 SM and 100 ft overcast. Weather remained solid IMC through at least 10000 ft. A normal takeoff was performed off runway 1. Upon passing 400 ft AGL we started a 1/2 bank turn (left turn) towards a 300 degree heading. This early turn was made in accordance with automated data procedures. Just prior to 1000 ft AGL the controller told us to turn further left to intercept dca 320 degree right. At 1000 ft low bank was deselected and the now full bank turn continued. A few moments later the controller said 'turn 15 degrees left before you hit the other one.' we did that and intercepted the dca 328 degree right. We were handed off to departure who gave us a phone number to call (dca TRACON). We never intended to penetrate P56. I believe we followed company and automated data procedures. (I did not receive automated data with the release. I contacted dispatch and received takeoff weights and departure procedures verbally.) the all engines operating automated data procedure off dca runway 1 states: 'all engines oeprating turn above 400 ft AGL ok.' company procedure reads that all early turns must be performed at '15 degree low bank maximum' until 1000 ft AGL at a speed not less than V2. This particular section refers to weather of 1000-3 or better. Just above that section is the reference that allows for early turns when required by 'special departure procedure.' as we were solid IMC; I read the combined procedures to say turn at 400 ft AGL (automated data procedure) and then climb in 1/2 bank to 1000 ft AGL (company procedure) and passing 1000 ft deselect 1/2 bank and continue with normal procedures. I think the 1/2 bank is what led to this event. I find no reference to a procedure that says we can use full bank in IMC on this departure (or in VMC for that matter). If we must use full bank to avoid P56 I would like to see a procedure to reflect that.

Title: AN ACR FLT CREW FLEW INTO A RESTRICTED AREA SHORTLY AFTER TAKEOFF WHILE FOLLOWING COMPANY PROCEDURES THAT LIMITED THEIR BANK ANGLE.

Narrative: WEATHER ON DEP WAS 1/4 SM AND 100 FT OVERCAST. WEATHER REMAINED SOLID IMC THROUGH AT LEAST 10000 FT. A NORMAL TKOF WAS PERFORMED OFF RWY 1. UPON PASSING 400 FT AGL WE STARTED A 1/2 BANK TURN (L TURN) TOWARDS A 300 DEG HDG. THIS EARLY TURN WAS MADE IN ACCORDANCE WITH AUTOMATED DATA PROCS. JUST PRIOR TO 1000 FT AGL THE CTLR TOLD US TO TURN FURTHER L TO INTERCEPT DCA 320 DEG R. AT 1000 FT LOW BANK WAS DESELECTED AND THE NOW FULL BANK TURN CONTINUED. A FEW MOMENTS LATER THE CTLR SAID 'TURN 15 DEGS L BEFORE YOU HIT THE OTHER ONE.' WE DID THAT AND INTERCEPTED THE DCA 328 DEG R. WE WERE HANDED OFF TO DEP WHO GAVE US A PHONE NUMBER TO CALL (DCA TRACON). WE NEVER INTENDED TO PENETRATE P56. I BELIEVE WE FOLLOWED COMPANY AND AUTOMATED DATA PROCS. (I DID NOT RECEIVE AUTOMATED DATA WITH THE RELEASE. I CONTACTED DISPATCH AND RECEIVED TKOF WEIGHTS AND DEP PROCS VERBALLY.) THE ALL ENGS OPERATING AUTOMATED DATA PROC OFF DCA RWY 1 STATES: 'ALL ENGS OEPRATING TURN ABOVE 400 FT AGL OK.' COMPANY PROC READS THAT ALL EARLY TURNS MUST BE PERFORMED AT '15 DEG LOW BANK MAX' UNTIL 1000 FT AGL AT A SPEED NOT LESS THAN V2. THIS PARTICULAR SECTION REFERS TO WEATHER OF 1000-3 OR BETTER. JUST ABOVE THAT SECTION IS THE REF THAT ALLOWS FOR EARLY TURNS WHEN REQUIRED BY 'SPECIAL DEP PROC.' AS WE WERE SOLID IMC; I READ THE COMBINED PROCS TO SAY TURN AT 400 FT AGL (AUTOMATED DATA PROC) AND THEN CLIMB IN 1/2 BANK TO 1000 FT AGL (COMPANY PROC) AND PASSING 1000 FT DESELECT 1/2 BANK AND CONTINUE WITH NORMAL PROCS. I THINK THE 1/2 BANK IS WHAT LED TO THIS EVENT. I FIND NO REF TO A PROC THAT SAYS WE CAN USE FULL BANK IN IMC ON THIS DEP (OR IN VMC FOR THAT MATTER). IF WE MUST USE FULL BANK TO AVOID P56 I WOULD LIKE TO SEE A PROC TO REFLECT THAT.
