E N D
3. ORLANDO FSDO-15 ACCIDENT & INCIDENT SUMMARY 1998 1999 2000 2001
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
4. WHY DO GEAR-UPS OCCUR ?
SUPERFICIAL CAUSE:
DISTRACTION OR NO CHECKLIST
REAL CAUSE:
INADEQUATE FLIGHT TRAINING IN RETRACTABLE GEAR OPERATIONS
5.
DEFICIENCY IN FLIGHT TRAINING CAN BE RESOLVED BY MODIFYING THE INSTRUCTIONAL METHODS USED DURING INITIAL AND RECURRENT RETRACTABLE LANDING GEAR TRAINING OPERATIONS
6.
THIS PRESENTATION IS DESIGNED TO PROVIDE AN EXTRAORDINARILY VALUABLE SET OF RETRACTABLE LANDING GEAR OPERATIONAL TECHNIQUES THAT WILL PREVENT A GEAR-UP LANDING
7. 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
8. 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
9. POSITIONS AND ASSOCIATED ACTIONS TO BE IMPRINTED TYPICAL TRAFFIC PATTERN
ABEAM TOUCH-DOWN: GEAR DOWN
14. POSITIONS AND ASSOCIATED ACTIONS TO BE IMPRINTED TYPICAL TRAFFIC PATTERN
ABEAM TOUCH-DOWN: GEAR DOWN
BASE: 2ND GEAR CHECK
17. POSITIONS AND ASSOCIATED ACTIONS TO BE IMPRINTED TYPICAL TRAFFIC PATTERN
ABEAM TOUCH-DOWN: GEAR DOWN
BASE: 2ND GEAR CHECK
SHORT FINAL: FINAL GEAR CHECK
20. 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”
21. POSITIONS AND ASSOCIATED ACTIONS TO BE IMPRINTED PRECISION INSTRUMENT APPROACH
SLIDE-SLOPE INTERCEPT: GEAR DOWN
26. POSITIONS AND ASSOCIATED ACTIONS TO BE IMPRINTED PRECISION INSTRUMENT APPROACH
SLIDE-SLOPE INTERCEPT: GEAR DOWN
500’ ABOVE DH: 2ND GEAR CHECK
28. 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
31. 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”
32. POSITIONS AND ASSOCIATED ACTIONS TO BE IMPRINTED NON-PRECISION INSTRUMENT APPROACH
FINAL APPROACH FIX: GEAR DOWN
33. POSITIONS AND ASSOCIATED ACTIONS TO BE IMPRINTED NON-PRECISION INSTRUMENT APPROACH
FINAL APPROACH FIX: GEAR DOWN
500’ ABOVE MDA: 2ND GEAR CHECK
34. 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
37. 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”
38. 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”
39. POSITIONS AND ASSOCIATED ACTIONS TO BE IMPRINTED NON-STANDARD ARRIVALS
“ALWAYS HAVE AT LEAST THREE GEAR CHECKS”
MOST IMPORTANT OF ALL:
FINAL GEAR CHECK
42. SUPPLEMENTAL TECHNIQUES
WHEN RETRACTING GEAR AFTER TAKEOFF, CONFIRM THAT IT GOES UP
44. SUPPLEMENTAL TECHNIQUES
WHEN RETRACTING GEAR AFTER TAKEOFF, CONFIRM THAT IT GOES UP
WHEN EXTENDING GEAR, PRIORITIZE TASK AND CONFIRM GEAR IS DOWN
49. 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
50. 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 ?
51. SYSTEMS KNOWLEDGE HOW TO RESOLVE SYSTEM MALFUNCTIONS
HOW TO CHANGE INDICATOR BULBS
HOW TO MANUALLY EXTEND GEAR
PUMP FAILURES
ELECTRICAL FAILURES
PARTIAL EXTENSION
52. GEAR UNSAFE LANDINGS WHEN GEAR IS NOT CONFIRMED SAFE
TOUCH DOWN SMOOTHLY
DON’T APPLY BRAKES
DON’T TURN OFF RUNWAY
STOP STRAIGHT AHEAD
EXIT AIRCRAFT & DON’T GET UNDER IT TO SEE IF GEAR IS LOCKED
53. GEAR UNSAFE LANDINGS WHEN GEAR IS CONFIRMED UNSAFE
FOLLOW EMERGENCY CHECKLIST
LAND ON PAVEMENT, NOT GRASS
TURN OFF FUEL
TURN OFF MAGS & MASTER SWITCH
UNLATCH CABIN DOOR
EXIT AIRCRAFT QUICKLY
54. ADDITIONAL CONSIDERATIONS TOUCH & GO LANDINGS ?
IDENTIFY AND VERIFY
DON’T DO TOUCH & GOES WITH GEAR REMAINING DOWN
TRAIN FOR NORMAL FLIGHT OPERATIONS
RIGHT SEAT TRANSITION
CFI BE READY
ARE YOU FIT TO FLY
FATIGUE OR MENTAL DISTRACTIONS CAN CAUSE FORGETFULNESS
55. SUMMARY
APPLY
SIGNIFICANT PRIORITY TO RETRACTABLE LANDING GEAR OPERATIONS
56. SUMMARY
DEVELOP AND USE POSITIONAL IMPRINTING
APPLY SUPPLEMENTAL TECHNIQUES
57. SUMMARY
EVALUATE ADDITIONAL CONSIDERATIONS
MAKE SURE YOU’RE FIT TO FLY
