for sure, you're not being told, you're being bullsh_t !!
Well, if the guys who told me fly under GA/GIA flight numbers, carry GA ID cards who flies PK-G** for a living... is it as you say... bullsh_t?
If I was the following traffic behind, at the same flight level in descent, at 10NM behind, and we had to go to select 210KIAS in order not to converge and later requested to deviate... is it as you say bullsh_t?
Maybe you should talk on your fellow former colleague D___nt__o... if I'm bullsh_tt_ng, then U're mate and his other current and former colleagues are too then...
SPD SEL 210 V/S -3000... welcome to the GA way! It's good that not all of them does it that way, and I hope that includes you.
