Importance of turning off unnecessary systems during operations.
Discussion around hydraulics and their effects on operations.
Aircraft Operation Details
Normal taxiing practices, such as single engine taxiing.
- Discussion on the use of an Auxiliary Power Unit (APU) on the 600 model.
- Reference to testing parameters and inhibited systems.
System Inhibitions and Parameters
At 17.23 knots, the anti-skid system is activated.
Brake system dynamics discussed:
- Brakes not operational until 35 knots.
- Touchdown protection activates at 35 knots during the first 5 seconds after touchdown.
- Sequence of operations and scenarios leading to potential misunderstanding noted.
Wheel Speed Differential Monitoring
Tire speed differentials monitored between left outboard, left inboard, right inboard, and right outboard wheels.
If a 50% speed differential is detected between any two wheels, the brakes are released automatically.
Annunciator Tests
Discussed systems not functioning during the annunciator test:
- ITT (Interstage Turbine Temperature)
- Fuel system.
- Additional systems that may not function during tests.
Leak vs. Overheat Definitions
Definitions clarified:
- Leak: Occurs between the duct and the Kevlar casing.
- Overheat: Occurs in specific line segments during operation.
System Reset Protocols
Reset procedures differ between leaks and overheat conditions:
- Leaks cannot be reset once triggered.
- Overheats can be reset after the system cools down.
Temperature and Altitude Operational Limits
Discussion of altitude and temperature standards:
- At Flight Level 240, the temperature is approximately -33 degrees Celsius at ISA (International Standard Atmosphere).
- If operating with one generator, altitude restrictions apply:
- Must descend to Flight Level 200 when temperatures are ISA +25 or higher.
Cooling and Performance Considerations
Importance of adjusting altitude concerning temperature and generator usage for optimal performance noted.
Discussion of systems affected by generator failures and their operational limits at high altitudes.
Reference to Aircraft Books and Material Preference
Preference for specific reference books and their quality in explaining concepts noticed and discussed.
