Hello,
I would like to post a few questions regarding the Thrust Reverser of the MD-11. I am student in aerospace, but my knowledge of the thrust reverser operations is still very limited and I would like to learn more.
I read somewhere that the T/R has two settings, what is meant by this? Do they mean the two "normal" settings of a T/R: reverse idle and reverse at (max) 50% thrust? Or does the MD-11 have a different reverser setting capability? Which operating mode is "normal" or is this pilots discretion?
Is there a specific cut-off speed for the application of the T/R or is this totally at the discretion of the pilot? If so, what is common practice during a landing?
Is it likely that operating the thrust reverser below the cut-off speed results in FOD or is there a certain margin? If FOD is likely below the cut-off speed, are there any incidents on record of FOD by using the MD-11 thrust reverser?
Side question: what is the average runway length used during landing of a MD-11 (combined version)?
Hopefully anyone can help me with these questions.
Kind regards.
