BAe146 update pics + video links

[mach7]

Hello All,

Here are a few update pic's and video links to my YouTube channel of my 146 progress.

A lot of interior work still needs to be done, but the overhead panel is now completely finished and interfaced and 95 percent of the fight instrument panel has been completed. I also need to tweek the control feel imputs for the Aileron and nosewheel steering.

Here are the links to the video's

Hydraulic panel operation. Note that I am still searching for OEM gauges, therefore the hydraulic quantity gauges say "temp" and the pressure gauges are graduated in percent:

Thrust management system operation, (TMS)....for those who are not familiar, is a "limited" auto throttle system that has numerous selections to help operate four engines with little or no effort. In this video example I am demonstrating the takeoff mode function.

In brief, at the end of each thrust lever teleflex cable is an actuator that can move 1/2 inch either side of centre to "fine tune" thrust inputs. In the takeoff mode, you dial in the outside air temperature if doing a full thrust takeoff, or the flex, (assumed), temp if doing a reduced thrust takeoff.

The system incorporates a computer to calculate all the necessary values, and has an input from a static pressure sensor to determine the pressure altitude. All it needs from you is the temperature input.

At the top of the CDU are engine identifier lights which show an upward pointing chevon, (blue), or a downward pointing chevorn, (white). The blue lights indicate to the Pilot that the actuator is fully extended and the white lights indicate the Pilot the actuator is fully retracted.

The way the system works is simple, before takeoff you select TOGA on the TMS CDU, then when the thrust levers are advanced above flight idle, the system becomes active and each actuator extends fully in an attempt to set the required thrust value. It takes a couple of seconds for each actuator to move to its fullest extent this is why the stagger in blue chevon light illumination. Having said this, the procedure is to hesitate with the thrust increase until all blue lights are illuminated.

Following this you would continue to push the thrust levers forward and when the actuators reach the required takeoff N1 value, they will begin to back drive hence extinguishing the blue identifier lights and fine tuning each engine independently within the range of the actuator. Should the Pilot push a lever too far forward, the associated actuator would reach its fully retracted position, thereby illuminating the white (downward pointing) chevron light, advising you to pull that lever back in order to get the actuator back into its range of authority.

As you can see from the video, I still have a lot of fine tuning to do on this unit as it setting takeoff N1 at 67 percent as opposed to the calculated value of 88.6 percent

Very cool - I got to try out a BAE146 sim the other day -

[OmniAtlas]

And landed it on my first go (with some assistance with AP most of the way)

If you are looking for real seats for your BAe 146, there is a pair listed at GLB Flight Products. Just sold two yokes earlier this year. That stuff is hard to come by so credit to you for choosing the aircraft for the cockpit build!
