Sorry I do not grew SIN should be #1. Still lots of shops are closed in the terminals (mainly Food outlets), and the additional QR codes still required for COVID are a joke.

Re: Boeing 777-300ERSF Freighter News and Discussion - 2023

AFAIK IAI has to make a lot of test flights to verify the enlarged flight envelope (higher operating weights), also the adapted software (777F - maneuver load allevation system) has to be demonstrated to the authorities, incl. smoke testing of the enlarged maindeck, compared to the 777F.

They could do a lot of things beyond simply raising the age to 67. One thing would be to allow them to fly, but not as CAPT, and only domestic. Japan implemented something like this, and it took hold at the regional level. Can't fly out of Japan above age 65, and can't fly anywhere with another pil...

Re: Airline Cruise Speed changing over decades

One other thing I will add that might contribute to the turning difference... The Airbus (at least the 330) limits bank angle above certain altitudes and at high true airspeeds. The 737NG does not. In fact, there were times we would limit the bank manually in the 737 when a heading was given at cru...

Technically speaking, the transition from indicated to mach is at FL280, although I typically assign indicated speeds FL290 and below, and mach FL300 and above.

The shape of them can change the lineup allowance from a 180 to a 90. Effectively increases the TORA.

TORA normally starts from the end of the yellow taxi line.
