Use of thrust reversers

Didn't take your comments as being critical. Just had to reexamine what I had said. Talking with the friend who flies the Super 72 now and used to fly the overpowered -7 72 with me just made me more sure of what I was saying.

He did say there was a difference between our reversers and those on the MD-80 engines used on the Super. When he said that, I could see where you were coming from.

Guess your FO needs listen closer to the ATIS landing weather if he/she can't tell by looking out that the runway is clear.

Spoilers do not suck. Engines suck - and blow.

AAflyer,

I'm surprised you take anything the "clownpilot" has to say seriously. A cursory examination of his posts should tell you that he either thinks he is being funny or just wants to start some sh!t. Either way, he contributes nothing worthwhile to this board and (along with a handful of others) is at the top of the IGNORE list.

Trainerpilot,

Funny you mentioned that, I was doing that for the last 15 minutes. He is a character. Actually he is full of sh!t, but boy is he witty.

I just wonder if he really flies for AA. Should ask him?
Hey, Would the real slim shady please stand up?

DC8 reverser..

On the DC8 reversers are deployed upon touchdown right away. They tell us we should not add power untill the nosewheel touches down. On the 70 series with the big fans you really don't need much power once they are deployed. On the 60 series you need quite a bit since they are not very efficient. Company procedures are to come out of reverse thrust at 80 knots and stow them at 60.
There are other situations that we use reversers and I'm not sure you can do it in any other aircraft. Often controllers hold you high (JFK most of the time) and the slam dunk you with a speed restriction. Since the DC8 does not have speedbrakes we get to use reversers in flight. (outboards only with the gear down) Just openning them without adding power drops you like a rock. Make it quite interesting.

in backing away from a terminal in a 727, i heard you should roll forward a little first and then deploy the reversers - otherwise you'll blow away the terminal

Well, well

Hey, mental midget Southwest wanna be.

What are you so pissed off about. That you can't get a job? That you paid $8000 dollar entry fee for a type rating that only gets you a chance to fly for an airline that pays 35% below industry standard, only flies to out of the way sh#tholes, flies only 1 airplane type for your entire life, and flies to Paris, but unfortunately its Paris, TX population 1,345, instead of Paris France?

Get over it troll. If you won't read my posts maybe one of your buddies will clue you in that you need to LIGHTEN THE H#LL UP.

This board is for entertainment. Fun. Ya know??? Don't spread your unemployed bad attitude around here.

The upside is that the top of your ignore list means you can't take bad news. But here's some for you. If you don't already have a job you ain't gonna get a decent one for years. With your attitude though I doubt your future holds much.

All my best to you.

Clownpilot....Heeeee's baaaack!!!!

 

[Clownpilot]

Heeeeeeeeeeeey

I refuse to reverse at effective higher speeds.

I refuse to hold light pressure against the interlock.

I refuse to apply reverse thrust once the interlock is released and the nose gear is on the runway.

However..................... If stoppping distance is critical I WILL:

Check spoilers deployed and remain deployed.

And I refuse to believe you missed the sarcasm in my original post BUT:

I will buy you a beer some time.

As for the type, I guess I forgot that one. Oh well.

Not sure what the hell my post has to do with you not using reverse thrust. I was talking about -9 and -7 engines, how underpowered they are.

As for not using reverse thrust. Take a look at your operating manual 1, approach and landing tab, pg. 40. Tell me what it says about reverse thrust.

I gotta hard time buying you fly for the same airline I do and get away without using reverse thrust on the 767/757.

Why didn't you get typed in the bird like everyone else?

Disclaimer: I've never done a power-back, but my father's done several hundred in the DC-9 and I've talked to him quite a bit about it.

My understanding is that the reason for rolling forward slightly is to get the tires off the "flat spot" created by sitting stationary for a couple hours. That way it takes less time and power to get the a/c moving.

Can anybody verify that for me?

And all this time I just thought the pilots were trying to scar the poop out of the folks waving from the windows up in the terminal...

"Scar the poop" out of them? That sounds awful!

It is!!! It is even worse than trying to scare the poop out of them...

IGNORE......

as in ignoramus

P.S. Don't work for SWA. Don't want to work for SWA. Didn't pay for any type ratings....my current employer (yes, I am employed...by one of the majors, so I guess my attitude is just fine) paid for my types in both aircraft types that we fly. Never been to Paris, TX, but I hear it's quite nice there. Kind of ironic, the "Clownpilot" lecturing someone about their attitude.

Get a life.

That said, back to IGNORE.

Re: Re: Well, well

I apologize for my assumption. That was careless of me.

Unfortunately for me I also have to send a letter of apology to Southwest Airlines. You see, I thought you at least had a viable job.

Southwest Airlines is 3.5 TIMES the size of your company.

You work for essentially a regional west coast airline.

SWA serves 6 times as many cities as you do.

SWA is growing.

SWA actually has a viable future.

Maybe AW will buy you. If they don't go under. The fact that you are considered a major is an industry joke. In fact, your revenue will probably drop below $1B this year and you wil lose your 'major' status.

LOL. All in fun. Good luck troll Alaska boy.

BTW, the fact that your largest airplane is a 737-900 is nothing to howl about. But, surely you must be furloughed. Or soon to be???????????.............

All my best. Hey if you can't take a joke you better stop looking in the mirror. LOL

IGNORE......

[FL717]

In the ERJ-145, I would always deploy the buckets upon main wheel touchdown, and depending on runway length, I sometimes, albeit rarely, would stay in idle reverse to around 60 kts and get lightly on the brakes before closing the buckets. This allows a smooth transition to brakes only. (This reverse to brake transition works on all aircraft that I have flown). Supposedly on the -145 the engines would not spool until nose gear touchdown, but I can attest that some did... some didn't.

On the DC-9, I always felt the reversers sucked in regards to effectiveness. What was cool is that you could touchdown, open the buckets and spool up to 80% N1, which was our target, while holding the nose off. Our SOP discouraged this technique, using a manufactures study against aerodynamic braking. At 80 kts idle reverse, and buckets closed by 60 kts. You would sometimes get a pop (compressor stall) and a forward surge if you waited too long and went from heavy reverse to normal idle too fast .... not that I know from firsthand experience or anything.... I've just heard?! Right!

The B-717 you have to get the nosewheel on the ground to get the buckets open and spooling, that is why you see the nose coming down so quick. The buckets would scrape the ground if they opened at main wheel touchdown. When the buckets open... you'd swear the other pilot was stomping on the brakes. They are the best!!

BTW... there was an Air Force study on C-9 (DC-9) that concluded that brakes above 100 kts heated up too quickly and made them less effective at slower speeds when you needed them. They recommended 80-100 kts max for brake application.

 

[PilotoHalcon]

The DC8 does not have in flight spoilers, other then roll control with gear down. BUT they do have inflight inboard reversers at idle thrust. It will get you down in a hurry. Since the planes are old they are to be used in a emergency situation only. But they are too cool to use in flight.
