I have been flying in DAR since 1992, i want to know about VIP movements...in DAR when there is a VIP movement, all other traffic is adviced to "standby start/taxi due VIP movement"...it could be so irritating and inconvenient...we once taxyied out of JNB to DAR together with 5H-ONE (presidential G 550) with the president on board, seemed like operations continue normally with VIP movements in JNB...WHERE ELSE IN THE WORLD IS MOVEMENT PUT ON STBY UNTIL VIP IS "SAFELY" AIRBORNE?...plz somebody advice
