Re: "THR CLB" v. "THR LVR"?

OK, thanks. So CLB LVR is not a 'thrust mode' then, as is CLB THR (if I have understood you correctly), it's just an indication to move the levers down from FLEX or TOGA. My procedure has always been OK, but I was assuming CLB LVR to be a detent (though that didn't make much sense to me - hence the...

Re: "THR CLB" v. "THR LVR"?

LVR is an abbreviation for "Lever". The Airbus thrust lever does not have a LVR or "lower" detent. There is a TO/GA detent for Maximum Take Off or Go-Around. There is a FLX/MCT detent for Maximum Continuous Thrust or Flex Take Off and there is a CL detent for Climb Thrust. Thrus...

Re: Historical question .. tail dragging aircraft

In my distant memory from an armchair pilot's viewpoint - early powered aircraft were tail draggers. This put pilots having to sit high or look out the side around the engine I guess. But why? Also tail draggers had to get moving to lift the tail requiring elevator control lest they pitch over. But...

There is no mechanism to stop the low-pressure spool from spinning. As FlapOperator says, unless it is seized somehow due to damage, it will spin.

There is indeed drag, but nowhere near that of an unfeathered propeller.

There is typically no hydraulic pressure before the first engine has started. So you can't run the actuators on hydraulics during engine start because hydraulic pressure is provided by the running engines.

The fuel pumps, however, will be running.
