Hi:
I am experiencing some issues with the L-1011 Pro. 1. During the climb when passing 10000 feet and pulling forward the trhottel to get a high spped, a terrible warning (bip) comes off. It does not stop until I reach agains below 10000 feets. 2. Maybe I am doing anything wrong but when landing after disconnecting th AP I can not have control of the levers of the plain. The plain does not respond to the yoke. I am very disapointed with the manual. I already submitted a ticket but while waiting maybe some body have any intelligent answer aroun here. Thank's

The first issue sounds like its possibly related to the cabin pressurisation system. We'll try to replicate the second issue as its not something we've come across.
You'll get a reply to your support ticket today. |

With the second issue, which you say is after landing, have you raised the flaps to disable Direct Lift Control (which is where the elevator channel operates the spoilers instead)? Just wondering if DLC might be your problem.

Than you Paul!.
I explained my self wrong. The issue is not exactly "after" landing but just before. The problem is when I release the AP during the approach to take control of the aircraft and land. At the very monet I release the AP can not gain full control of the plain. I can not put down or lift the nose of it.

That sounds like you need to practise with the DLC! I've not tried the transition from autopilot to manual, but in purely manual approaches (less than 90% rpm, gear down, moving the flaps to 33 will enable direct lift control. I'm sure it's in the manual, it's not instinctive and really takes some getting used to. You have to have the aircraft in the landing attitude before selecting flaps 33 and then use the evevator axis to control rate of descent - the attitude should remain pretty constant provided you are below max landing weight.

10 000 ft warning I set before t/o the altitude at the cabin peressurization panel. If I forget this, I get the warning. It´s possible to see it down below at the warning-messages, there should be the ECS light on.
Flying with DLC is a new experience and the system will try to hold the plane stable during approach. I´m not a real pilot, can not decide what´s wrong or not. Before I flow the Captain Sim L1011. The approach is similar. The only difference I saw was the "Alpha" information at speed-window when I set Flaps 33 in Captain Sim. So I first expected to see "Alpha" here again, but it´s not shown. The approach speed I used from the table left in the cockpit depending on Weight of the airplane. Which can be easy found at the fuel panel, where actual fuel and weight are shown. If the speed is reasonable before setting flaps 33, there is no problem to fly manually. If the speed is too high, the plane will try to decrease the speed for flaps 33 setting with the spoilers I think. If thrust decrease at the same time, it losts altitude and if the pilot try to pitch up, it wouldn´t work because this would decrease the speed of the plane again. Flying manually the L1011 the pilot must know during approach, pitch changes speed, thrust changes altitude. Uncorrect speed and thrust during approach leads to loss of altitude and speed when flaps 33 are set. The plane doesn´t know the distance to the runway, the system tries only to get a smooth glide path down. Maybe flying online ATC wants the pilot to fly minimum 170 knots until outer marker. Then I wait with flaps 33 until I reach outer marker. Otherwise the plane slows down and would be a obstacle for following airplanes. Maybe I´m wrong, but this way I have no problems to control the approach manually. Functional the DLC works fine. Question is, should there be the "Alpha" announcment in the speed window or not? In the Captain Sim this was the information for me, NOW! DLC will correct my inputs. Another question is the Altitude. With FMS flying, when I change the altitude after TOD, the airplane directly starts descent. Do not know this is correct. I expected first I had to set V/S to begin with descent. With other planes I do this: Get from ATC "When ready to descent ... Altitude" I set the altitude at MCP. I know. this is the next altitude I´m allowed to fly. I calculate the TOD and V/S, later I set it and start descent. Now I notice the new altitude on a paper and wait until optimum point of descent to set the new altitude on MCP. It´s not bad because when the workload is high, it´s faster to follow ATC instructions when a direct descent is needed. I need only to change the altitude at MCP and the descent begins. Maybe there are different versions of L1011. For example the CS has no Autobrakes, which JF have. The JF-Pro-Version is much better than the old version before. Good work! |
