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
