Narrative:

We lost contact with dfw tower following the controller's acknowledgement of our missed approach on runway 36L. We went around after encountering brief severe turbulence during rapidly deteriorating surface WX conditions (advancing line of trw's). The loss of contact caused us to have to fly a less than desirable course through moderate to heavy WX. There was no clearly apparent reason for the communication breakdown, which lasted probably 1-2 mins, and it came at a critical time. The controller had been giving us timely, important information from the time we checked in. His clearance to land for us was accompanied by wind direction, speed and gust, an alert that we could expect a 20 plus KT increase in airspeed at 200 ft AGL, and that the pressure was rapidly rising. This information was repeated just as we encountered the brief severe turbulence. We detected stress presence in his voice as the surface conditions were certainly deteriorating, and his workload was increasing. Only review of the tape would clarify how long the break took and what his last instructions to us were (I have forgotten), but we felt very much 'on our own' for a considerable length of time. Dfw is notorious for rapid fire, high pressure controling. In this case, the controller was on top of the situation and of great assistance until the break in xmissions. In a similar situation in the future, I would specifically request a favorable course in the event of a miss and would expect quick coordination from the ATC facility.

Title: LGT LOSES CONTACT WITH TWR DURING A MISSED APCH.

Narrative: WE LOST CONTACT WITH DFW TWR FOLLOWING THE CTLR'S ACKNOWLEDGEMENT OF OUR MISSED APCH ON RWY 36L. WE WENT AROUND AFTER ENCOUNTERING BRIEF SEVERE TURB DURING RAPIDLY DETERIORATING SURFACE WX CONDITIONS (ADVANCING LINE OF TRW'S). THE LOSS OF CONTACT CAUSED US TO HAVE TO FLY A LESS THAN DESIRABLE COURSE THROUGH MODERATE TO HVY WX. THERE WAS NO CLRLY APPARENT REASON FOR THE COM BREAKDOWN, WHICH LASTED PROBABLY 1-2 MINS, AND IT CAME AT A CRITICAL TIME. THE CTLR HAD BEEN GIVING US TIMELY, IMPORTANT INFO FROM THE TIME WE CHKED IN. HIS CLRNC TO LAND FOR US WAS ACCOMPANIED BY WIND DIRECTION, SPD AND GUST, AN ALERT THAT WE COULD EXPECT A 20 PLUS KT INCREASE IN AIRSPD AT 200 FT AGL, AND THAT THE PRESSURE WAS RAPIDLY RISING. THIS INFO WAS REPEATED JUST AS WE ENCOUNTERED THE BRIEF SEVERE TURB. WE DETECTED STRESS PRESENCE IN HIS VOICE AS THE SURFACE CONDITIONS WERE CERTAINLY DETERIORATING, AND HIS WORKLOAD WAS INCREASING. ONLY REVIEW OF THE TAPE WOULD CLARIFY HOW LONG THE BREAK TOOK AND WHAT HIS LAST INSTRUCTIONS TO US WERE (I HAVE FORGOTTEN), BUT WE FELT VERY MUCH 'ON OUR OWN' FOR A CONSIDERABLE LENGTH OF TIME. DFW IS NOTORIOUS FOR RAPID FIRE, HIGH PRESSURE CTLING. IN THIS CASE, THE CTLR WAS ON TOP OF THE SITUATION AND OF GREAT ASSISTANCE UNTIL THE BREAK IN XMISSIONS. IN A SIMILAR SITUATION IN THE FUTURE, I WOULD SPECIFICALLY REQUEST A FAVORABLE COURSE IN THE EVENT OF A MISS AND WOULD EXPECT QUICK COORD FROM THE ATC FACILITY.
