HOW TO AVOID A GEAR-UP LANDING Presented By Larry Enlow Aviation Safety Inspector Federal Aviation Administration Orlando Flight Standards District Office
ORLANDO FSDO-15 ACCIDENT & INCIDENT SUMMARY 1998199920002001 TOTAL ACC. & INC. 185 176 147 141 TOTAL GEAR-UP 35 26 19 11 TOTAL TRAINING A & I 60 38 24 28 TRAINING GEAR-UP 17 10 4 9 TNG. GEAR-UP WITH CFI 11 10 4 9
WHY DO GEAR-UPS OCCUR ? SUPERFICIAL CAUSE: DISTRACTION OR NO CHECKLIST REAL CAUSE: INADEQUATE FLIGHT TRAINING IN RETRACTABLE GEAR OPERATIONS
DEFICIENCY IN FLIGHT TRAINING CAN BE RESOLVED BY MODIFYING THE INSTRUCTIONAL METHODS USED DURING INITIAL AND RECURRENT RETRACTABLE LANDING GEAR TRAINING OPERATIONS
THIS PRESENTATION IS DESIGNED TO PROVIDE AN EXTRAORDINARILY VALUABLE SET OF RETRACTABLE LANDING GEAR OPERATIONAL TECHNIQUES THAT WILL PREVENT A GEAR-UP LANDING
RETRACTABLE LANDING GEAR TRAINING CONCEPTS PRIORITIZATION AIRCRAFT OPERATIONAL TASKS AND ASSOCIATED CHECKLIST ITEMS DON’T ALL HAVE THE SAME VALUE RETRACTABLE GEAR OPERATIONS HAVE SIGNIFICANT PRIORITY, AND MUST BE EMPHASIZED BY CFI
RETRACTABLE LANDING GEAR TRAINING CONCEPTS POSITIONAL IMPRINTING IMPRINTING MEANS: “TO IMPLANT FIRMLY ON THE MIND OR FIX IN THE MEMORY” POSITIONAL IMPRINTING MEANS: “TO FIX IN THE MEMORY THE ASSOCIATION BETWEEN POINTS IN SPACE DURING FLIGHT OPERATIONS AND THE NEED TO EXTEND OR RECHECK THE LANDING GEAR IN THE DOWN POSITION
POSITIONS AND ASSOCIATED ACTIONS TO BE IMPRINTED TYPICAL TRAFFIC PATTERN ABEAM TOUCH-DOWN:GEAR DOWN
POSITIONS AND ASSOCIATED ACTIONS TO BE IMPRINTED TYPICAL TRAFFIC PATTERN ABEAM TOUCH-DOWN:GEAR DOWN BASE: 2ND GEAR CHECK
POSITIONS AND ASSOCIATED ACTIONS TO BE IMPRINTED TYPICAL TRAFFIC PATTERN ABEAM TOUCH-DOWN:GEAR DOWN BASE: 2ND GEAR CHECK SHORT FINAL: FINAL GEAR CHECK
POSITIONS AND ASSOCIATED ACTIONS TO BE IMPRINTED TYPICAL TRAFFIC PATTERN ABEAM TOUCH-DOWN:GEAR DOWN BASE: 2ND GEAR CHECK SHORT FINAL: FINAL GEAR CHECK “ALWAYS HAVE AT LEAST THREE GEAR CHECKS”
POSITIONS AND ASSOCIATED ACTIONS TO BE IMPRINTED PRECISION INSTRUMENT APPROACH SLIDE-SLOPE INTERCEPT: GEAR DOWN
POSITIONS AND ASSOCIATED ACTIONS TO BE IMPRINTED PRECISION INSTRUMENT APPROACH SLIDE-SLOPE INTERCEPT: GEAR DOWN 500’ ABOVE DH: 2ND GEAR CHECK
POSITIONS AND ASSOCIATED ACTIONS TO BE IMPRINTED PRECISION INSTRUMENT APPROACH SLIDE-SLOPE INTERCEPT: GEAR DOWN 500’ ABOVE DH: 2ND GEAR CHECK RUNWAY IN SIGHT: FINAL GEAR CHECK
POSITIONS AND ASSOCIATED ACTIONS TO BE IMPRINTED PRECISION INSTRUMENT APPROACH SLIDE-SLOPE INTERCEPT: GEAR DOWN 500’ ABOVE DH: 2ND GEAR CHECK RUNWAY IN SIGHT: FINAL GEAR CHECK “ALWAYS HAVE AT LEAST THREE GEAR CHECKS”
POSITIONS AND ASSOCIATED ACTIONS TO BE IMPRINTED NON-PRECISION INSTRUMENT APPROACH FINAL APPROACH FIX: GEAR DOWN
POSITIONS AND ASSOCIATED ACTIONS TO BE IMPRINTED NON-PRECISION INSTRUMENT APPROACH FINAL APPROACH FIX: GEAR DOWN 500’ ABOVE MDA: 2ND GEAR CHECK
POSITIONS AND ASSOCIATED ACTIONS TO BE IMPRINTED NON-PRECISION INSTRUMENT APPROACH FINAL APPROACH FIX: GEAR DOWN 500’ ABOVE MDA: 2ND GEAR CHECK RUNWAY IN SIGHT: FINAL GEAR CHECK
POSITIONS AND ASSOCIATED ACTIONS TO BE IMPRINTED NON-PRECISION INSTRUMENT APPROACH FINAL APPROACH FIX: GEAR DOWN 500’ ABOVE MDA: 2ND GEAR CHECK RUNWAY IN SIGHT: FINAL GEAR CHECK “ALWAYS HAVE AT LEAST THREE GEAR CHECKS”
POSITIONS AND ASSOCIATED ACTIONS TO BE IMPRINTED NON-STANDARD ARRIVALS VISUAL APPROACHES BASE ENTRIES STRAIGHT-IN ARRIVALS “WHEN YOU START DOWN, PUT YOUR GEAR DOWN”
POSITIONS AND ASSOCIATED ACTIONS TO BE IMPRINTED NON-STANDARD ARRIVALS “ALWAYS HAVE AT LEAST THREE GEAR CHECKS” MOSTIMPORTANT OF ALL: FINAL GEAR CHECK
SUPPLEMENTAL TECHNIQUES WHEN RETRACTING GEAR AFTER TAKEOFF, CONFIRM THAT IT GOES UP
SUPPLEMENTAL TECHNIQUES WHEN RETRACTING GEAR AFTER TAKEOFF, CONFIRM THAT IT GOES UP WHEN EXTENDING GEAR, PRIORITIZE TASK AND CONFIRM GEAR IS DOWN
SUPPLEMENTAL TECHNIQUES WHEN RETRACTING GEAR AFTER TAKEOFF, CONFIRM THAT IT GOES UP WHEN EXTENDING GEAR, PRIORITIZE TASK AND CONFIRM GEAR IS DOWN AFTER LANDING, CLEAR RUNWAY, STOP AIRCRAFT, THEN IDENTIFY AND VERIFY EACH ITEM BEFORE MOVING IT
SYSTEMS KNOWLEDGE THOROUGH UNDERSTANDING OF RETRACTABLE GEAR SYSTEM IS ESSENTIAL TO AVOID A GEAR-UP • HOW DOES SYSTEM OPERATE ? • HOW DOES WARNING SYSTEM WORK ? • HOW IS SYSTEM PROTECTED FROM INADVERTENT OPERATION ON THE GROUND ?
