Reverse Thrust

Recommended Posts

For the life of me I cannot seem to activate reverse thrusters after touch down.

I'm thinking that I must have adjusted something, because I have managed to

reverse thrust before....

 

Any ideas?

 

Thanks!

which controller are you using ?

 

Are you assigning the reversers to a button or to an axis ?

 

are you using FSX axis assignment, or FSUIPC ?

Hi Tjueten

 

Saitek X 52

 

Reversers are set to F2 keyboard

No assignments in fsuipc

I have noticed this as well, to an extent. With the NGX I used to just press F1 then F2 to idle reverse whereas this method doesn't work for me in the 777 on landing. Instead I just set up a button on my joystick to essentially act as F2 and I just hold it down for a second or so.

I have the Saitex X52 Pro with Thrust Reverse assigned to the "Fire D" button on the Throttle this is programmed to press F2 for Thrust reverse, I also have the Joystick Trigger second position mapped to press F1  this works fine and is quite logical as brakes are set to the first position on the Joystick Trigger is assigned to brakes so when I pull it into the second position it cancels Reverse Thrust and disarms the Autobrake and I you can continue to brake using the first position.

 

Works OK for all my Aircraft.

Could it be that if the speed brake is not armed then reverse thrust will not activate?

I have the X52 Pro Saitek too, using FSUIPC and LINDA for assignments.

 

In FSUIPC, throttles are assigned but not calibrated (as recommended by PMDG). They are "Sent to FSX as normal axis".

 

I've mapped the reverser axis to the thumb slider on the throttle. Works well.

 

I don't think the speedbrake must be armed in order for the reversers to work.

Reversers are independent of anything else - only limitation is aircraft must be on the ground.

 

Best regards,

What is the default for the 777 to idle the engines and reverse thrust? Is it F1 & F2 like the ngx (the tutorial indicates it is) and I haven't remapped any keys. I had a good landing today and then I just frickin went flying down the runway and couldn't stop. It was an autoland vs my other landings where I had disabled AP prior to touchdown, so i was wondering if that may have played some role in it.

Was Autobraking set? Did you leave the AP on? If AP and AT is set ON for landing and roll and you don't switch them off you NEED to have Autobraking set!

Use the Saitek control panel to create a small null zone at the idle end of the throttle travel. Based on your description I'd say chances are the throttle is sending a slight signal at the idle position and that is cancelling the reverse thrust. I have a Saitek X52 with a null zone at the idle point and I have not encountered this issue.

 

Cheers

I don't have the T7, but does it behave the same way as the NGX with regards to the reverse? The NGX reverse DOES NOT activate until the flight idle decreases to ground idle, that is some seconds after touch down. I tried all F1 and F2 combinations but I never get the reverse to activate as soon as I touch down.

One reason to use manual throttle because you go to idle 10-15 seconds before touchdown then as you you touch you can go straight to reverse!

What do you mean with "manual throttle"? Of course I don't use A/T and I pull the throttle back to idle already about 10-15 seconds before touch down, but the reverse engages only after the idle goes to ground idle and this happens only some seconds after touch down.

 

Is the nose wheel still in the air when you attempt to engage T/R?

 

No, it is on the ground.

I don't see this at all. I can operate reverse thrust immediately after touchdown. It is independent of the flight/ground idle transition.

Hello Mark

 

Could you be more more specific please? I have a problem and looks like with your suggestion I can solve it

 

When I try to apply the reverse when the airplane is in the ground I can't, I don't know why but when I'm in taxi to the gates I apply the reverse and works perfect

 

My configuration is : ( I have the x52 Saitek)

 

IN FSX i have assigend 0 to Reverse Quickly and my x52 profile the botton that I have in reverse (button D in the Throttle) I have a Advance command named "Reverse" and in that actions i have in PRESS section, number 0 with 15 seconds when the button is released, same configuration as PRESS in REPEAT and finally in RELEASE section I have F1 (F1 is assigned in "Throttle out" in my FSX)  (The action release in the advance command is for back the Throttle to the end possition when botton D in the throttle is released)

 

But is I said is not working that all just in Taxi when everything is slow but in landings is not working :(

 

May be you can be more specefic in your description :D

 

Please help :(

 

Thanks a lot

Hello Guys

 

I'm using X52 and is very simple use reverse Throtte without FSUIPC

 

Go to Profile editor for X52 and select the button that you want for reverse

 

- Right click on the button and select New Advance Command

- Select a Name for that command for example Reverse or name wathever you want

- In Press Section push and relsease F2 (Be careful F2 should be assigned in FSX Buttons and Keys as Throttle Decrease NOT Decrease quicky)

- In Repeat same thing push and release F2

- in Release section Select F1 (In FSX Buttons/Keys F1 should be assigned as Throttle cut)

 

Translating the command to words :D 

When you push button assigned in the X52 the FSX will take as you are pressing the F2 key if you still pressing the button the Repeat section will interpret that u are still pressing the F2 and when you release the botton the FSX will interpret that u are pressing F1 (Throttle cut)

 

Simple

 

Other thing I saw in some forums that some guys are asking for move the spoilers gradually because in FSX config we just have ARM and activate (don't remember the name) So if you want to move the spoilers gradually you should use the Precision Slide and to configure this in FSX just go to Control Axes and select Spoilers Axis and when u are in the box move the Precision Slide and that's it :D

 

Hope this helps

(sorry for my horrible english structure lol)

I experience the same thing as OP. ILS autoland. So the throttles already go to idle in the flare 15-20 feet above ground.

 

It doesn't seem to want to go to REV immediately. I have to hold down F2 for a second or two before the amber REV is annunciated on the EICAS. No FSUIPC.

Remember the 777's N1 rotation speed. If you pay attention to the EICAS on roll-out you'll see the engines are still moving to idle even on the ground, hence the delay. Reverse thrust will only activate once the engines are at idle, which does take a few seconds to occur. So no mistake from PMDG.

FSX does not wait for N1 to go to idle before enabling reverse. You can check this by setting take off thrust then holding F2. The reversers deploy well before N1 gets to idle.

 

There is no mistake by PMDG. Any problem relates to how users calibrate their throttle hardware.

Yeah I've had the reverses actually go to REV straight after touchdown, maybe once.... normally have to keep spamming my shortcut to get them out shortly after touchdown (pressing F2 has no different effect). Rather annoying - even with AT disconnected throughout the approach to landing phase!

Hi there,

 

just did a touchdown. Manual flying but with engaged autothrottle in spd sel (147kts). Thrust got to idle about 20-30ft above runway and I was able to hit F2 to go to reverse. I'm also using X52 but I managed to follow pmdg suggestions to NOT calibrate or assign buttons in fsuipc or another tool.

I always get reverse straight after touchdown. We both run FSX with PMDG addons. So neither can be the cause of any difference. If our results are different the only explanation can be how we set up and calibrate our throttle hardware.
