As I understand, the standard procedure for advancing the throttle (for take-off) is as follows:
- Advance throttle to desired engine input & output (N1 & N2)
- Release brakes
- Gradually increase the throttle to maximum
- Throughout steps 1-3 either the pilot or the co-pilot control the throttle but not both
However, in this video of a B-52 we see a rather strange way of controlling the throttle. Starting at 0:44 the pilot and co-pilot take turns advancing the throttle in an inside-out manner. What is the reason behind this? Is there really a standard procedure for advancing throttle? Or does it vary based on the aircraft?
