FCTM 8.x [Leading Edge or Trailing Edge Device Malfunctions] Approach Review the approach chart : Published procedure turns and radar vectors that are executed at a speed below flaps up maneuvering speed,

Typical tail clearance during takeoff is between 50 and 75 cm / 20 and 30 inches. This clearance increases with flap setting. Consider using Flaps 15 for takeoff with low gross weight. Subtract about 2

FCTM 8.x [Hydraulic System(s) Inoperative - Landing] X with one or both hydraulic system fluid quantities not zero, verify the EDP. The EMDP are located in the E&E, so these pumps cannot be reset in

Make sure you are not dealing with a single or dual engine failure! Advance thrust levers and verify engine response. ENG FAIL should not be displayed. Verify MCP settings - values may have dropped back

Note : An engine in-flight start is not allowed if %N1 or %N2 shows zero rpm There in no minimum oil quantity requirement for an engine in-flight start. However, after engine start, oil quantity should

According to the NNC an increase in fuel imbalance of 230 kg / 500 lbs or more in 30 minutes should be considered an engine fuel leak. However, bear in mind that not every fuel leak is an engine fuel leak
