In this video of a carrier landing, you can see the constant throttle manipulation by the pilot.... Especially as he nears touchdown. Do these turbojet engines have that quick of a throttle response?
I always thought there was a time lag when power was applied, to when it was actually received? This because it takes time for the engine itself to, "spool up".
From around the 0:40 second mark, up to when he applies full throttle just before touchdown, he's all over the place with the throttles.
Yes, you do move the throttle a lot, and yes, the engines do respond that quickly. They’re “spooled up” and running at a high RPM.
The F/A-18 (in all its various forms) has a LOT of drag when in the landing configuration. Those huge trailing edge flaps and drooped ailerons allow it to fly slow enough to land, but crate a great deal of drag. Because the drag is so high, the thrust has to be high, so the engines are in the high RPM range and respond instantly.
Older airplanes, like the A-6 or F-14, that had high lift wings, didn’t have that much drag when landing, so, their landing configuration included extended speed brakes. It was part of the F-14 landing checklist, for example “Speed Brakes…extended”. That extra drag from the extended speed brakes allowed the engines to be in a higher RPM range and offer better throttle response.
The F-14 still had poor throttle response in the landing configuration - both because the wing was so efficient and because the engines were still at a modest RPM even with speed brakes extended.
As an illustration of the differences in airframe - an F-14, at 54,000 lbs landing weight, actually used slightly less fuel/min in the landing configuration than a 32,000 F/A-18C.
All that said - this guy is rough on the throttles. Some guys are smooth. Some aren’t. This guy is rough. I’ve flown the airplane, and this is not the best technique.
