What to look out when ATC busy
Traffic and headings due stress.
Remind him from time to time
do you want us to hold?
Look out on diversion fuel
holding frequency
126.5
MSA awareness
Stay away
Speed max 250 below
use fix info
Use 100nm radius fix info
Due cruise tends to be FL300, Quicker to decide where to go during emergency descent
When a failure appears after flight, what to fill in?
Take the post flight report and
TP ATA code then title
To make SOUSA FL due short track, what to do
limit take off weight as 75 for A321
60 for A320
