That is to say, if taking off from a high-altitude airport, such as Lhasa, after the THR RED ALT is already above 10000 feet, the &#8220;10\u00b0\/CLB&#8221; should be skipped and &#8220;5\u00b0\/CLB&#8221; should be directly executed.<\/p>\n<p>Secondly, FL100 doesn&#8217;t distinguish between the QNH and STD, right?<\/p>\n<p>&nbsp;<\/p>\n<p><strong>A<\/strong><\/p>\n<p>In this <span style=\"color: #ff0000;\">particular case (thrust reduction above FL 100)<\/span>, the flight crew should maintain a pitch of 15\u00b0 with TOGA thrust as long as the aircraft is below the Thrust Reduction Altitude.
