Yes Ram777 that's how it should be done. You decide, depending on situation, the exact time to close the thrust, sometimes you may have to leave a bit on until touchdown.


Q---2 dots high? Ans:- Ease forward on the elevator to reduce the pitch attitude by say 1 to 2 deg? That increased your ROD ( obviously ) then perhaps you "may" have to reduce thrust a little, say 5% N1 to keep the IAS nailed. Then when back on slope ease up 1 to 2 deg and apply 5% more N1 to maintain the slope. All Jet Pilots are trained in what pitch attitude and thrust setting to aim for in approach, initially on conversion you fly these NUMBERS. Later on you "just do it"

Haven't you guys see the unreliable Airspeed checklist which contains a table showing you PITCH ATTITUDE and THRUST settings ??

Any of you flown the A330 using the BUSS? ( yes Noodle do you know what the BUSS is? )

Airbus strongly recommend and teach that during an approach flown by the BACKUP SPEED SCALE ( BUSS ) that to maintain in the green you fly a fixed pitch and then adjust THRUST to keep it IN THE GREEN. Why? Because that's the easiest way to remain "stable" AND keep the process as normal as is possible.

This is "their training" using Thrust to control speed just as you do ON A NORMAL LANDING.


P.s. I would have loved to read what 411A would have said about his beloved L1011. That beast used DLC and in theory your Pitch attitude remained constant, still they used Thrust for Speed though!!
