Narrative:

Aircraft a: beechcraft kingair 300 (T/BE30/right). Aircraft B: cessna 172/182. Aircraft a taxied from ramp to holding area for runway 35. IFR clearance was received prior to taxi from houston clearance, frequency 119.25: a hold for release was issued with the clearance. PNF informed houston clearance that aircraft a was #1 for departure and a release for takeoff was given by houston clearance. Unicom 122.97 was monitored. Traffic pattern scenario was as follows: inbound commuter aircraft on downwind behind 4 small single engine aircraft either on downwind or long straight in to runway 35. The commuter aircraft (stretch merlin) being the faster aircraft made a short approach (becoming the #1 aircraft) and landed long using all the runway and turned off at the end. (Sgr equals 8000 ft times 100 ft with 1984 ft displaced threshold: threshold is available for takeoff) aircraft B called 1 mi final to runway 35, at which time aircraft a called departing runway 35, moved onto the runway and commenced takeoff roll. At this time a transmission was made over the unicom for aircraft a to hold in position. Aircraft a held on the threshold of runway 35. A 2ND transmission was made on unicom asking if we were going to continue holding in position. PNF on aircraft a responded to the 'affirmative.' approximately 2-2.5 mins later PNF on aircraft a requested the position of the landing aircraft B. Response from aircraft B was 'on top of you' -- aircraft B landed normally beyond the displaced threshold, approximately 1800 ft beyond aircraft a. The scenario, although not a major breach of safety, presented the possibility of a potential problem situation. The factors affecting this situation: 1) extremely busy uncontrolled environment. 2) breakdown of communications, cockpit discipline and aviation courtesy when mixing high and low performance aircraft. 3) lack of coordinated efforts in sequencing IFR and VFR aircraft. A higher degree of 'situational awareness' on behalf of all involved can decrease the possibility of a recurrence of this type of scenario.

Title: CORP ACFT MOVES ONTO RWY WITH ACFT ON 1 MI FINAL.

Narrative: ACFT A: BEECHCRAFT KINGAIR 300 (T/BE30/R). ACFT B: CESSNA 172/182. ACFT A TAXIED FROM RAMP TO HOLDING AREA FOR RWY 35. IFR CLRNC WAS RECEIVED PRIOR TO TAXI FROM HOUSTON CLRNC, FREQ 119.25: A HOLD FOR RELEASE WAS ISSUED WITH THE CLRNC. PNF INFORMED HOUSTON CLRNC THAT ACFT A WAS #1 FOR DEP AND A RELEASE FOR TKOF WAS GIVEN BY HOUSTON CLRNC. UNICOM 122.97 WAS MONITORED. TFC PATTERN SCENARIO WAS AS FOLLOWS: INBOUND COMMUTER ACFT ON DOWNWIND BEHIND 4 SMALL SINGLE ENG ACFT EITHER ON DOWNWIND OR LONG STRAIGHT IN TO RWY 35. THE COMMUTER ACFT (STRETCH MERLIN) BEING THE FASTER ACFT MADE A SHORT APCH (BECOMING THE #1 ACFT) AND LANDED LONG USING ALL THE RWY AND TURNED OFF AT THE END. (SGR EQUALS 8000 FT TIMES 100 FT WITH 1984 FT DISPLACED THRESHOLD: THRESHOLD IS AVAILABLE FOR TKOF) ACFT B CALLED 1 MI FINAL TO RWY 35, AT WHICH TIME ACFT A CALLED DEPARTING RWY 35, MOVED ONTO THE RWY AND COMMENCED TKOF ROLL. AT THIS TIME A XMISSION WAS MADE OVER THE UNICOM FOR ACFT A TO HOLD IN POS. ACFT A HELD ON THE THRESHOLD OF RWY 35. A 2ND XMISSION WAS MADE ON UNICOM ASKING IF WE WERE GOING TO CONTINUE HOLDING IN POS. PNF ON ACFT A RESPONDED TO THE 'AFFIRMATIVE.' APPROX 2-2.5 MINS LATER PNF ON ACFT A REQUESTED THE POS OF THE LNDG ACFT B. RESPONSE FROM ACFT B WAS 'ON TOP OF YOU' -- ACFT B LANDED NORMALLY BEYOND THE DISPLACED THRESHOLD, APPROX 1800 FT BEYOND ACFT A. THE SCENARIO, ALTHOUGH NOT A MAJOR BREACH OF SAFETY, PRESENTED THE POSSIBILITY OF A POTENTIAL PROB SIT. THE FACTORS AFFECTING THIS SIT: 1) EXTREMELY BUSY UNCTLED ENVIRONMENT. 2) BREAKDOWN OF COMS, COCKPIT DISCIPLINE AND AVIATION COURTESY WHEN MIXING HIGH AND LOW PERFORMANCE ACFT. 3) LACK OF COORDINATED EFFORTS IN SEQUENCING IFR AND VFR ACFT. A HIGHER DEGREE OF 'SITUATIONAL AWARENESS' ON BEHALF OF ALL INVOLVED CAN DECREASE THE POSSIBILITY OF A RECURRENCE OF THIS TYPE OF SCENARIO.
