Narrative:

While working south local control at O'hare tower, air carrier X, a runway 14R departure penetrated protected airspace for arrs to runway 13C at midway airport. A subsequent loss of separation occurred between air carrier X the O'hare runway 14R departure and an aircraft Y midway arrival to runway 13C. The definition of the airspace to be protected in the O'hare 7110.65, 4-1 is unclr. Both the classroom and on-the-job training I received was incorrect. Any procedure for a runway 14R departure when the south satellite airspace for midway is required to be protected is unsafe and incorrect. Even with prior pilot compliance, a heavy jet requiring runway 14R, 13000 ft cannot be expected to, or depended upon to, complete a 50 degree turn within 2 mi of the departure end of the runway in IFR WX. Therefore any such operation is at best a gamble.

Title: ACR X UNCOORD PENETRATION OF AIRSPACE HAD LTSS FROM ACFT Y. SYS ERROR.

Narrative: WHILE WORKING S LCL CTL AT O'HARE TWR, ACR X, A RWY 14R DEP PENETRATED PROTECTED AIRSPACE FOR ARRS TO RWY 13C AT MIDWAY ARPT. A SUBSEQUENT LOSS OF SEPARATION OCCURRED BTWN ACR X THE O'HARE RWY 14R DEP AND AN ACFT Y MIDWAY ARR TO RWY 13C. THE DEFINITION OF THE AIRSPACE TO BE PROTECTED IN THE O'HARE 7110.65, 4-1 IS UNCLR. BOTH THE CLASSROOM AND ON-THE-JOB TRAINING I RECEIVED WAS INCORRECT. ANY PROC FOR A RWY 14R DEP WHEN THE S SATELLITE AIRSPACE FOR MIDWAY IS REQUIRED TO BE PROTECTED IS UNSAFE AND INCORRECT. EVEN WITH PRIOR PLT COMPLIANCE, A HVY JET REQUIRING RWY 14R, 13000 FT CANNOT BE EXPECTED TO, OR DEPENDED UPON TO, COMPLETE A 50 DEG TURN WITHIN 2 MI OF THE DEP END OF THE RWY IN IFR WX. THEREFORE ANY SUCH OP IS AT BEST A GAMBLE.
