PK-KAR :Try flying behind Garuda... 210 KIAS below 20,000... but, at times... if say they're held at 7000, and get told to go down to 2000... U'll see them dive @300KIAS or so :o ... the reason being many new FOs I'm told, keep SPD on 210 on the MCP, but select V/S at 3000fpm... *puke*
for sure, you're not being told, you're being bullsh_t !!
saying 210KIAS blo FL200, you better have FOQA record.
do you really have Mach Airspeed indicator ?
