February 4, 20206 yr 12 minutes ago, cobo said: So increasing throttle only pushes forward normally, but once the Reversers are activated (idle first then activate reversers) the flow will be diverted to front from back output instead of back output. So if you notice at landing on jetliners while traveling, at touchdown and increase throttle rate will be selected by flight crew. Xplane11 is modeling this just right. No, again, that's not how it works IRL! The throttles/thrustlevers are either staying at idle and by moving the separate reverse thrust levers you control the amount of reverse thrust. Or the throttles/thrustlevers can be moved from the idle position further backwards into the reverse range and reverse thrust is being modulated by the amount of backward travel.

In fact, If you use FS Passengers, there is a penalty if used below 60 knots. Used to be much more common on jets with rear mounted engines (the MadDogs and the 727 for example) because the engines are mounted higher and there is much less chance of the engine ingesting something. Mostly banned because it's also pretty dangerous. Lots of stuff around the ramp that can get blown about and the amount of thrust used to get rolling (backwards) is more than it is to get rolling forwards.

Engines will get started after pushback, at Houston and some other airports seen an area designed to start up.
February 4, 20206 yr On many airports engines are being started during pushback. Saves lots of time and space on the apron/taxiway.

Ok, I think I get it, we are talking different aircraft. Boeing, and Airbus have different than Q400 for example. My apologies if I'm missing something, but on the Q400 I have to apply reverse by making the levelers in back motion. Boeings are: Touchdown, idle, engage reverse levelers, apply forward motion to Throttles.
February 4, 20206 yr Just now, cobo said: Boeings are: Touchdown, idle, engage reverse levelers, apply forward motion to Throttles. NO! That's plain and simple wrong.
February 4, 20206 yr 7 minutes ago, cobo said: Boeings are: Touchdown, idle, engage reverse levelers, apply forward motion to Throttles. Main gear down, throttle idle, pull up the reverse levers until they hit the interlock, wait a couple of seconds, and then pull them up further to increase thrust as needed. The main throttle levers do not move from idle. Edit: There are at least a couple of types that can (could) deploy the reversers in flight.... Edited February 4, 20206 yr by b737800

I can see why you say that, and this is as per my conversation with pilots at airports, they may or not apply more thrust depending on landing, it may be just lever engage and throttle when more is required. I have been in landings where no reversers got engaged. I fly ( as passenger) on a weekly basis. so I been in almost every aircraft there is (not all) from Beechcraft to A380. And some of them I spilled my wine all the way to the luggage compartment. Beechcraft I was (first passenger seat) left the cockpit door open, and I got to observe all including approach and landing at Denver. Denver and Phoenix have giving me the most interesting landing experiences as a passenger. Edited February 4, 20206 yr by cobo

I have been in landings where no reversers got engaged. And again, no. It works exactly as b737800 explained and it's the same on all Airbuses as well (except the A320 family) Reverse thrust higher than idle is prohibited on most airports due to noise, but idle reverse is usually always immediately selected at mainwheel touchdown for various reasons.

Or the throttles/thrustlevers can be moved from the idle position further backwards into the reverse range and reverse thrust is being modulated by the amount of backward travel. The HotStart TBM900 has an innovative solution for the second example. Quite natural indeed. You can only move your ingame thrust lever back to a certain detent. Actually you can move it further on your hardware of course. If you want to move it below that detent (beta & reverse range), you have to press the reverser button to unlock. Once you move it back above this position, the detent will snap in again. I hope I could describe this somewhat comprehensive. 🙂 Edited February 4, 20206 yr by tweekz Happy with MSFS 🙂 home simming evolved

The Trident was the first one that sprung to mind. I think one the the Tupelovs too perhaps. For some reason I believe the reversers weren't locked out so you COULD deploy them inflight even if you weren't supposed to. Then of course there was the Lauda 767. Tragic.

There are numerous great youtube videos of DC-9s, MD-80s, IL-62, Tu-154 etc. landing with open reversers. Edited February 4, 20206 yr by FDEdev

So, is it most airports in some countries, or world wide, or plane dependant, wet/slippery runway, or what? Edited February 4, 20206 yr by GlideBy My brother has Coronavirus, confirmed by testing. On 3/26 he almost didn't survive the night. He had extreme trouble breathing and was given a steroid inhaler. He was very weak, had nausea, and other issues that aren't pleasant. As of this update he is feeling much better, and seems he will be fine. Stay safe out there. (Updated 4/6)

The sliders and doors are far too subtle and don't have the same tendency to fall off. Borderline boring.
