Re: Why are today's flight times longer than 25 years ago?

Not sure about Europe, but in the US, the growth of RJ’s and private jets really strained the system for a long time, and still do. Before this, turboprop commuters flew at lower altitudes, while jets flew in the 30’s or 40’s. When RJ’s came along, they took up space flying at the same levels as th...

Re: FAA issues EAD for the Airbus A220, citing two “near catastrophic incidents”

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.

At F100, 320 KIAS is 362 KTAS, so you’d only 37 knots of tailwind to have ground speed of 399 knots. If the crew the leveled off at F100 to accelerate from min clean of around 270 KIAS, this is very explainable.

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.
