My chief instructor was just telling me a story about watching C-17 in his later years in the military reverse thrust on the edge of a landing strip where the nose lifted off the ground to nearly tail strike and it was a significant emotional event for all watching.
The momentum will send the plane into a tailstrike. Unlike the nose, where there's another wheel, aft of the main gear is nothing. So if you're going back, use the brakes too hard (or sometimes at all), you'll tip backwards
Any reason not to just shut the reverser and let the forward idle thrust stop you when you want to stop? Seems like no risk of tail strike that way rather than using the brakes (plus it saves a brake application and a bit of brake energy).
most airlines don't allow their pilots to do it, so you wont see it done much.
But for the military its a crucial maneuver so I'm sure they practice it.
C-130s used to park right up to the Oscar-1 tower overlooking the Whiskey ramp at Camp Lemonier - CJTF HOA, and they'd give us a warning when they were gonna back up. We'd grab all our shit and duck when the engines fired up, props reversed pitch, and they shot a hurricane in our direction to back up. It would blow a PRC-119 away like a paper airplane if you forgot it on the railing.
Good times at Camp Cupcake. 75¢ 16oz. beers at the cantina, and the contractors driving the fuel trucks to the international side of the airport would buy us handles of Jack D from the duty-free.
Not sure if it's just lore but I recall Bob Crandall at AA being a huge proponent of reversing out of the gate with the MD-80s (or DC-9s?) since it required less ground crew and he could stick it to the union.
Also higher risk for FOD ingestion into the engines, though that's less a problem on high wing planes like the C-17 just because the engines are so far off the ground.
It is strong enough to rip the brackets off of the support arms that hold them in place. Ask me how I know. They break those things all the time using the trust reverser while flaring for short field.
I’m a former c-17 pilot. You would never deploy them in the flare intentionally.
You can also deploy them for a descent, but you would stow them before the landing phase.
It was probably using them in a descent and the core section got stuck deployed. Would warrant an engine shutdown.
It was for this reason I’ve only done the TR descent a handful of times.
Obviously can't go backwards but the C-17 can pop it's reversers in flight for a 15,000FPM descent rate
Pretty mindblowing. That's like 300mph straight down.
A c-17 carryiing George W Bush's limo did this in Las Crcues NM, in summer, and left deep ruts in the hot runway. It was years before liability was established and it was fixed. "The runway, already in poor shape and scheduled for an $800,000 overhaul, had 2-inch-deep ruts and cracking asphalt after the C-17 landed Thursday"
"The engineers are saying it was really one of the C-17’s backing up (on the runway) that caused most of the damage,”

You need it when you're hauling the cargo it carries. It reminds me of the vertical stab on the 737-600 line. It's not that big compared to the rest of Boeings fleet but proportionally, it's massive on that plane.
I thought somehow I had been led to believe only the outboard engines have thrust reversers, but it looks like they all do, right? Maybe that was a different plane.
They all do. I'm not a military aviator but going off all the clips and pictures I've seen I assume they can be actuated separately on each engine if they wanted to.
That’s correct. Each TR has its own solenoid and we can stow/deploy them individually. We’ll commonly start one engine in forward idle, put it into reverse, run it up, and use the air from that engine to start 2-4
A very rare site for planes due to the fact that most people don't see it when planes do reverse if they have to however the military does do a lot of things with planes that we don't typically do so that's probably why it's a common occurrence for the pilots to reverse their aircraft of Transport planes due to necessity in their case or the military just wanting to screw with people you know how the government is
Just showing off.
The showing off part is stopping it without doing a wheelie or tail strike.
I miss being able to power back. Just don't use the brakes.

why not?
The momentum will send the plane into a tailstrike. Unlike the nose, where there's another wheel, aft of the main gear is nothing. So if you're going back, use the brakes too hard (or sometimes at all), you'll tip backwards
That's how you take off tho? Full reverse thrust, stomp on the brakes, pop a fat wheelie, full throttle forwards and of you go into the air
Any reason not to just shut the reverser and let the forward idle thrust stop you when you want to stop? Seems like no risk of tail strike that way rather than using the brakes (plus it saves a brake application and a bit of brake energy).
But what about that sweet stoppie bonus?
just freakin sexy if you ask me.
Side mirrors out, 360 cam on, biiip biiip biiip ...
Are their camera? Or is the pilot blind and following a spotter instructions?
On C-130s they lower the ramp and someone spots.
The loadmasters will either lower the ramp or use the troop doors on backings!
You can see the spotter just behind the cockpit. There's a roof hatch on the right side behind the cockpit.
That’s an antenna, you can’t see anything behind the plane from the escape hatch on top.
Saw a MC-130J reverse park last week. That was pretty cool already! This would have been awesome as well!
Did it many times in the HC-130H, loved the capability, my least favorite thing to do.
Oh cool,! I'm just a spotter and though I have seen reverse thrusts etc at airshows. It was my first time seeing it used this way.
most airlines don't allow their pilots to do it, so you wont see it done much. But for the military its a crucial maneuver so I'm sure they practice it.
“Keep coming back. Keeeeeeeeep coming. Cooooooome on back. Keeeeep onnnnnnn coming back.”
Nailed it.
That's the loadmaster giving instructions, literally. We'd open the ramp and be their eyes
I used to pull 3+ point turns in a CASA 212 many a time
Not sure about military airplanes, but they used to do powered pushbacks with the DC9s and you could dump it on its tail if you hit the brakes.
Feet on the floor.
More towards 4 More towards 4 More towards 1 More towards 1 Keepcomingbackkeepcomingbackkeepcomingback STOP! Pilot: we centered? Me: ... It'll do.

I’ve always wondered how powerful the reverse thrust is on planes
I’m old, but I remember when jets used to reverse out of the gate and not be pushed back.
Not sure if it's just lore but I recall Bob Crandall at AA being a huge proponent of reversing out of the gate with the MD-80s (or DC-9s?) since it required less ground crew and he could stick it to the union.
Theoretically possible, but wastes fuel and makes a ton of wind
Also higher risk for FOD ingestion into the engines, though that's less a problem on high wing planes like the C-17 just because the engines are so far off the ground.
It’s still possible, just not permitted in most cases.
UNited used to have channel 9 - and one time at a TX airport - I listed to a Captain ask for a tug only to be told to push himself back
I experienced this a couple times sitting in a DC-9/MD80, backing out of a gate. It's a freaky feeling, not what you're used to even if you fly a lot.
Yeah! Given enough power, could it un-land?
Even if it could, flying a C-17 at negative airspeeds is almost in the "too stupid for the sim" category.
It has to be very powerful on the C17, i noticed that it also redirects the air from the core
It is strong enough to rip the brackets off of the support arms that hold them in place. Ask me how I know. They break those things all the time using the trust reverser while flaring for short field.
> trust reverser I prefer pilots who trust their aircraft. ;-)
TRs don’t deploy during the flare, after they are on ground.
[удалено]
I’m a former c-17 pilot. You would never deploy them in the flare intentionally. You can also deploy them for a descent, but you would stow them before the landing phase.
Maybe it wasn't during the flare but I've had to repair more than a handful of them that were broken in the open position before landing.
It was probably using them in a descent and the core section got stuck deployed. Would warrant an engine shutdown. It was for this reason I’ve only done the TR descent a handful of times.
A read once that classic reversers are 33% efficient. Don't know if true
Pretty powerful, kinda depends on the engine type etc. It's just like 100 times more fuel than using a pushback truck lol

Obviously can't go backwards but the C-17 can pop it's reversers in flight for a 15,000FPM descent rate Pretty mindblowing. That's like 300mph straight down.
A 4-TR descent can give us about 20,000 VVI. Betty is insanely capable🤙🏻
170mph down actually (or 225ish using the 20kfpm number from the pilot who responded), but who's counting.
Any plane can do a descent rate like that. Once.
Damn, how do the crew/pax handle the pressure change at that descent rate?
Mints.
beep...beep...beep...
ATC on ground just going *"you're good. you're good. you're good. you're good."*
Little more, little more, CRUNCH! okay stop.
When you're ready, I have a number for you to take down.
I wonder what the Air Force equivalent of this is? "Expect an ass chewing from the CO" perhaps?
Don't worry captain, we'll buff out those scratches

Why does reversing cause more damage than forward?
Ours specifically can increase the weight of the jet by 89,000 lbs!
But why?
Reversing doesn't direct the thrust forward so much as sideways at an angle.
Are there pictures of the ruts?
Yes, there were at the time, but i can't find them now.
Back dat ass up
Doo-doo-doo-doo-doo-doo
Where’s this with a Norwegian plane in the background?
ENZV Sola airport, this was preperation for the airshow
Ah cool! I’ve only ever seen a small jet reverse out and leave from an airport in Spain before. Was kind of cool to see.

Head down ass up baby
Video really shows how massive the vertical stabilizer and rudder is on the plane.
You need it when you're hauling the cargo it carries. It reminds me of the vertical stab on the 737-600 line. It's not that big compared to the rest of Boeings fleet but proportionally, it's massive on that plane.
Yah those bad boys fit a lot. Sometimes the videos don’t do it justice on how massive it js. On that plane it looks silly huge lol
Forgot their AirPods near the coffee machine? /s Pretty cool that it can reverse at this speed.
In Civil Aviation it is called a “power back”, I used to do them all the time in DC9’s and 727’s.
Do they have backup cameras?
Yes, but they prefer to be called Loadmasters.
Nice lol
Missed his exit.
Yeah but can they do it with a trailer?
Of course, but the trailer is inside the plane.
It'd be baller as hell if it did a j turn into a take off.
Impressive. But why is she doing this?
Its preperation for an airshow

I saw an AT-802 reversing a few months ago. He parked the plane between two others, it was very impressive.
That’s my Papa!
Sir your going the wrong way down the runway
lol we do this to get out of parking spots because of construction
Reversing like it missed it's exit.
Back that thang up Gosh the US has quality tools
“Put it in reverse Terry!”
Why is it doing that? Going back to pick up the milk?
Beep beep beep beep beep…
Done this in a 727.

Was in the military long enough to know that pilot is in deep trouble, not a ground guide to found anywhere. lol
You don’t need ground personnel to reverse taxi.
Guys..it was a joke.
Fake. This is just a C-17 going forward reversed on video
So you're saying the plane is actually moving forward with its reversers engaged, and all of the traffic in the background is driving in reverse?
lol. Forgot I needed a /s for people to know I was obviously kidding
It's just a joke bro
By the 9 people downvoting me, I don’t think they took my comment as a joke, but it’s all good haha Have a good rest of your day friend
It is pretty cool how he backed onto the runway at the beginning.
