A "sealed" slat has no slot between it and the main wing. According to b737.org.uk, sealing flaps allows for more lift at a lower AOA (Angle of Attack). Reference from Flightglobal.com "Short Field 737 goes into flight test" states that sealing of up to 25 degrees of slats will be available for take-off, an improvement from 1 and 5 degrees. Slots (not ...

The Maximum Taxi Weight (MTW) is one of the weight limitations in the FCOM: (Boeing 737-800 FCOMv1 L.10.3 Limitations - Operating Limitations - Weight Limitations) It can be the limiting factor when the actual takeoff weight including required fuel is very close to the MTOW and adding taxi fuel would get you above this limit. Note that the difference ...

Does this clearance allow me to fly a reciprocal of 020 inbound to the station? Or will I just have to fly away from the station on 020 radial? A radial is always pointing away (radiating) from the VOR. The clearance therefore instructs you to fly away from the VOR on the 020 radial. Will a left turn be more appropriate than a right turn to intercept ...

When turning on the Anti-Ice, the demand for bleed air increases and the EEC (Electronic Engine Control) will increase the target N1 to provide enough pressure by injecting more fuel. From the Boeing 737 NG FCOMv2 (7.20.5 Engines, APU - Engine System Description, emphasis mine): In the normal mode, the EEC uses sensed flight conditions and bleed air ...

Turning on Engine Anti-Ice causes the engine idle N1 to automatically increase so that it can supply additional bleed air and not flame out. This means that for descent planning, an earlier descent should be planned since idle N1 is now producing higher thrust.

The latest findings of cracks in less than 20000 cycles (Lion Air, 2 planes), and 13% of cracked pickle forks in South Korean fleet are beginning to look really bad. This is a design flaw, no doubt about it. As for how serious of a design flaw, I cannot judge. If the cracks would impose an immediate risk to flight safety, I bet the officials around the ...
