Narrative:

We were cleared out of 7000' for 4000. Passing 5200' we were told to maintain 5000' with traffic at 12 O'clock and 3 mi. An air carrier Y medium large transport was told to expedite out of 5000' and was told he had traffic (us) at 12 O'clock and 3 mi. He reported us in sight. We then picked the air carrier Y medium large transport up at 9 O'clock and 1 mi, approximately 500' below us in a descent. He went into the cloud deck and passed underneath. Our radio altimeter momentarily flickered to 1200'. The rest of the approach and landing were uneventful. Conclusion: the potential for mishap existed. If we had missed the altitude amendment call or went lost communication I believe a mishap would have occurred. Recommendation: the air carrier Y medium large transport was on a straight in to orl runway 18L, and was 9 mi north of the field. We were on a heading of 090 degrees across his path for runway 17 when the conflict occurred. I recommend that in the future we be vectored over the top of the field to set up for a left downwind for runway 17.

Title: CLOSE PROX ACR-LGT ACR-MLG IN MCO TRAFFIC ON CROSSING PATTERNS.

Narrative: WE WERE CLRED OUT OF 7000' FOR 4000. PASSING 5200' WE WERE TOLD TO MAINTAIN 5000' WITH TFC AT 12 O'CLOCK AND 3 MI. AN ACR Y MLG WAS TOLD TO EXPEDITE OUT OF 5000' AND WAS TOLD HE HAD TFC (US) AT 12 O'CLOCK AND 3 MI. HE RPTED US IN SIGHT. WE THEN PICKED THE ACR Y MLG UP AT 9 O'CLOCK AND 1 MI, APPROX 500' BELOW US IN A DSNT. HE WENT INTO THE CLOUD DECK AND PASSED UNDERNEATH. OUR RADIO ALTIMETER MOMENTARILY FLICKERED TO 1200'. THE REST OF THE APCH AND LNDG WERE UNEVENTFUL. CONCLUSION: THE POTENTIAL FOR MISHAP EXISTED. IF WE HAD MISSED THE ALT AMENDMENT CALL OR WENT LOST COM I BELIEVE A MISHAP WOULD HAVE OCCURRED. RECOMMENDATION: THE ACR Y MLG WAS ON A STRAIGHT IN TO ORL RWY 18L, AND WAS 9 MI N OF THE FIELD. WE WERE ON A HDG OF 090 DEGS ACROSS HIS PATH FOR RWY 17 WHEN THE CONFLICT OCCURRED. I RECOMMEND THAT IN THE FUTURE WE BE VECTORED OVER THE TOP OF THE FIELD TO SET UP FOR A LEFT DOWNWIND FOR RWY 17.
