Line Check 2025 Flashcards
What are the crosswind/tailwind components limitations?
Hard Dry or Wet Runway: X32kt T10kts
Contaminated: Standing Water, Slush, Loose Snow: X14kts T0kts
Compacted Snow: X20kts T0kts
These limitations indicate the maximum allowable wind components for various runway conditions.
What are the engine operating temperature limits?
Temperatures: -50ºC or ISA +35ºC, -54ºC (With bypass doors open MTOP and MCP power settings limited to ISA+25ºC)
Max ITT: 920ºC (880º-920º max 20 seconds)
ITT stands for Interstage Turbine Temperature.
What is the maximum torque limit for NTOP?
Max torque: 90.3%
NTOP stands for Normal Takeoff Power.
What are the taxi speed limitations?
25kts Straight, 15kts turns
Narrow 15-18m: 15kts, 10kts in turns
These speeds are critical for maintaining control during ground operations.
What is the minimum hydraulic system requirement for dispatch?
System 1, 2: 40%
System 3: 45%
These percentages ensure adequate hydraulic power for safe operations.
What is the total usable fuel capacity?
Total usable fuel: 5318 kg (5150 used for planning)
This figure is important for weight and balance calculations.
What are the APU operational limitations?
Must be shutdown prior to takeoff
Must not be operated unattended with pax on board
Must not be operated during gravity refuelling
APU stands for Auxiliary Power Unit, which provides power for ground operations.
What are the APU temperature limits?
Minimum: -35ºC
Maximum: 50ºC or ISA+35
These limits are essential for safe APU operation.
What are the APU starter limits?
1 min/2 min
1 min/2 min
1 min/30 min
These limits dictate the operational cycles for starting the APU.
What is the maximum APU load meter limit?
Max APU load meter is not to continuously exceed 1.0
Exceeding this limit could risk damage to the APU.
What is the normal cabin differential pressure limit?
Normal Cabin diff limit: 5.46 psi +/-0.1 psi
Max Cabin diff limit: 5.95 psi
These limits are crucial for maintaining cabin pressure during flight.
What are the autopilot limitations?
Autopilot limitations (10):
- disengage in severe icing
- Pilot seated at controls with safety and shoulder harness fastened
- Use of VOR without associated DME not permitted in APP mode
- Takeoff and Go-around engagement above 1000ft AGL
- On approach disengage by 200ft AGL
- Disengage in Severe turbulence
- Autopilot approach must not be commenced with inoperative engine,
- disengage by 1000ft AGL
- AP and FD approaches approved for glideslope angles of 2.5º-4º
- AP approches have been demonstrated in 18kt crosswind
These limitations ensure safe autopilot operation during critical phases of flight.
What should be done during a rapid depressurisation?
Emergency descent procedures must be initiated
This is crucial for passenger safety and cabin integrity.
What is the standard brace order phraseology?
“ATTENTION! BRACE BRACE BRACE!”
This phrase alerts passengers to prepare for impact.
When should Aerodata be used for landing performance calculations?
Preflight, inflight, and prior to landing to ensure LDR is less than LDA
LDR stands for Landing Distance Required and LDA stands for Landing Distance Available.
What is the maximum landing weight?
Max Landing Weight: 28,123 kg
This weight limit is critical for safe landings.
What are the oxygen pressure limits for standard flight crew?
1300/1800 psi
These pressures ensure adequate oxygen supply for crew safety.
