'Disregard' meaning & uses?
Posted: Tue Jan 24, 2017 6:07 am
Hello all,
I had a somewhat confused moment yesterday when flying off from Bakersfield to San Luis Obispo. This will probably seem trivial and obvious to some or perhaps funny to others but I thought I would share.
I was holding short of RWY 30R & ready for departure, got given my clearance for takeoff by ATC, then shortly after ATC issued a new message : 'FBTPC, Bakersfield Tower... disregard', which led me to think my takeoff clearance had been cancelled, so naturally I applied the brakes & kept clear of the runway.
A few seconds later, it became quite clear that ATC was just directing an approaching traffic to use the adjacent runway instead - ensued was me still holding short 'just in case' before calling back a few minutes later to ask if it was really ok for me to depart.

Was I right to be confused, cautious?
Is there an official / approved usage of the term 'disregard' for communications? What portion of a message does the disregard actually 'disregard' : the previous transmission, or the current transmission? Similarly & from what I understand, a pilot using the word 'take off' outside of the clearance for takeoff read-back is highly discouraged. Is there a similar rule for ATC to cancel takeoff clearances?
