That’s true, at 60 knots the AT goes into HOLD, which is annunciated on the PFB, which means thrust is set at whatever thrust exists at 60 knots and the AT won’t adjust thrust until airborne. HOLD also allows the pilot to go IDLE, in the event of a rejected takeoff without interference from the clut...

Might as easily blamed the union negotiators for trading sick or PTO for more money. This exact trade-off has occurred in many union contracts. I’m sure if a trade for x% less raise for 5 days of sick, it would have been costed out and perhaps included in the final deal.

In the ‘60s, there were series of mid-airs involving high speed airliners and GA planes that led to the regulation. Four in 67 and 68, plus the NYC collision between UA and TWA. At the time, no speed rules, so it wasn’t unusual to fly at 300+ at low altitudes.

According to my Jeppesen, in the Singapore FIR, the 250knots/10,000 only applies to arrivals. Also, 250 KIAS is 288KTAS at 10,000’ on standard day, plus/minus any wind for ground speed.

A heavy 744 or 777 will climb better at 320-340 KIAS, so if allowed, will do so.
