Presentation Transcript

    1. “WHEEL AND LANDING GEAR EMERGENCIES” Robert Thompson Randy Krause

    2. “HOT BRAKES”

    3. Boeing Dash 80 Brake Test1954

    4. Dash 80 Video

    5. OBJECTIVES Causes of Hot Brakes Hazards Approaching the aircraft Dealing with the emergency Extinguishing agents

    6. Causes of Hot Brakes Aircraft weight Landing speeds Extraordinary braking Refused take- off (RTO)

    7. Hazards Tire failure Fusible plugs Disintegration of wheel assembly Danger zone ( Approx. 300 feet )

    8. Approaching the Aircraft Establish communication with pilot Approach from front or aft Type of aircraft Observe tire condition Is there smoke or fire ?

    9. EICAS - Flight Display(Engine Indication Crew Alert System)

    12. What are we going to do ? Is there fire? Do we need to evacuate the aircraft? Can the aircraft taxi? What are my exposures?

    14. Extinguishing Agents Dry chemical Dry powder Foam Water Dual agent

    15. A New Way of Thinking

    16. Cera-Metalic/Composite Brakes All new Aircraft have them Most older Aircraft have changed to them Will withstand higher temps than steel by absorbing and dissipating heat better

    17. Boeing Flight Test Minor temperatures - air or water cool Extreme temperatures - cool with water If Fusible Plug fails - temperatures are extreme

    18. Airborne Command Post RTO Edwards AFB 1973

    19. Command Post Video

    20. Water When using water: Approx. 1500 gal. per wheel set Use hand line / snozzle / turret Cool entire wheel and brake Be aggressive!

    22. Fire If fire is present: Small tire fire - use water Large fire - treat as any aircraft fire attack with large amounts of water & if fuel cell’s are compromised use foam!

    23. Steel Brakes If tires have deflated Brakes are already warped! Water will not matter at this point

    24. “LANDING GEAR EMERGENCIES AND TIRE FAILURE”

    25. NOSE GEAR Tire Failure Gear Damage Gear not down and locked in place Possible Belly Landing WATCH OUT!

    29. MAIN GEAR Give plenty of room! Set up on good gear side

    30. 9/23/03 JFK

    32. PINNING OF GEAR Military Fighters Have the right pins for Aircraft involved Know where they go Check with the Flight Crew

    33. 747-400 ER Brake TestEdwards AFB 2002

    34. 747-400 ER Video
