So in a demonstration on why to lockout hydraulic equipment the demonstrator goes into the path of the reverser several times with the unlocked reverser and hydraulics on

He never went into the path of the reverser with hydraulics on. You may being mistaking the sound of the equipment cooling fan for the hydraulic pump.

I think that most airlines will go for the reverse option since it helps to keep their airplanes on the runway in adverse conditions. There is a considerable economic benefit for doing that.

You can have the best braking system made but they are useless if your tires are hydroplaning and / or can't get a grip on the runway.

Absolutely. I have blown both mains on one side and needed differential reverse to keep the airplane on the runway. I will not bid an aircraft with no reversers.

Maybe someone else has posted this but I think it should be an excellent summation regarding this subject.

I have an 85 page Power Point on the subject but there little new to say beyond the Briefing leaflet.

the BAe-146 didn't have thrust reversers, so it's not like this is a revolutionary concept.

They have a manually selectable ground idle setting which reduces forward thrust (it makes a noticeable difference to deceleration rate). Also large and powerful speedbrakes.

Quoting BravoOne (Reply 16):

Yes we get your point. Also the Folker 100 did not have TR's either as I recall. Just means it was an airplane built around compromise and not what worked best

The Fokker 100 has reverse thrust. It was the F.28 that didn't have it. Maybe the higher landing weight of the Fokker 100 meant a thrust reverser was necessary?
The glass isn't half empty, or half full, it's twice as big as it needs to be.

That is very well written, should be required reading for all those who doubt the importance of reverse thrust.

Don't forget - the A380 only has 2 thrust reversers due to the capacity and engineering of the aircrarft brake system. Also, the BAe-146 didn't have thrust reversers, so it's not like this is a revolutionary concept.

There were quite a few of the EMB145's delivered without thrust reversers.

Twice I believe.

The driving force behind not ordering those EMB's without T/R's was saving the maintenance cost of the T/R's.
One has to wonder if the insurance rates increased for operating that model of airframe without T/R's to the point that no money was saved?
