Reverse Thrust On Taxi

Hi IFC,
I experienced something super strange yesterday. On my flight TK1809, the pilots used reverse thrust on taxi.
Is this normal?

Do you mean for pushing back? Or for braking while taxiing?

They sometimes do that if they need to stop quickly in slippery conditions.

Why? This is real world aviation, seems like the right place to me…

Seems like the aircraft was a B739, i don’t even think they can do that while taxiing tbh, and if they did i don’t think it’s very good for the engine.
Would love to get some of the RW Pilots opinion on this

Ummm you’re able too only by going over a certain speed. You’re not supposed to though?

It’s often used to slow the aircraft down whilst taxing long distances to the departure runway in hot weather in order to keeps the brakes cool.

High engine twin jets use it, not recommended in Airbus or Boeing jets as the risk of ingesting FOD is quite high, especially if your pods are over the edge of the taxy way.

You must have ever seen this! This B757 used its reversers because he missed the runway exit in his turn

Guaranteed the skipper would be asked to explain his actions in this one!

There are laid down procedures for doing a 180 turn on the runway and using reverse thrust isn’t one of them!!! Once you start moving backwards it’s very difficult to control the speed/brake without tipping the aircraft on it’s tail!

What they did was pretty risky/dangerous IMHO.

However, to justify my previous comments, this is on the runway, not the taxy way ;D

It was an A321

While taxiing.

Did the pilot actually apply thrust and slow the aircraft? Reversers activation without power while taxiing to the runway is a common preflight check.

Yes, he conducted this 3 times. Each time the plane ended at a full stop shortly after.

This video is really interesting. It may be also because there are probably no pushback trucks at Skiathos airport.

It’s quite normal if the plane is a prop. It can actually shift to a “R” gear by reverse trust.

I’d be willing to bet that they just opened them, but didn’t actualy use them, just checking them same reason they lower, and raise the flaps, and wiggle the alirons while you taxi…

I remember from watching a video from VASAviation where an A380 diverted to PHL from JFK they asked if the stand they were using at PHL would let them pushback on there own power which I would assume means reverse thrust.

It could be the engine in idle. Doesn’t mean you are actually reversing. If you are taxiing too fast this helps the aircraft slow down, fokkers used to have to taxi with one open at a certain airlines because otherwise the aircraft would get too fast. But reverse thrust isnt being used.

Selection of the reversers will always give you some sort of reverse thrust vectoring, that’s the point.

On the 777 we only have reverse idle and full reverse. Selecting reverse idle (first detent on the reverse thrust levers upward pull) opens the engine cowls, inserts the flow dividers and applies a little ‘extra’ idle reverse thrust to the engine speed.

There is no option, on any aircraft I’ve flown, to just ‘check’ the doors/buckets without activating the whole system thus applying reverse thrust as commanded.
