Hello Simmers, With this flight I wanted to see how the FDE works when trying to land with more then the approved MLW. Result: Some flouting in ILS GS and the Tail Section wants to see the ground before the Main Landing gear reaching the Rwy.  Also the Landing Rate was at arround 350 feets. Not my best landing but worth to share it with you. Can anyone tell me the enginge start sequence of the 727? I always performe like in the DC10 1,3,2. Have fun Regards Michael |

Nice 727-video. Since you had landed the 727 above MLW, does she suffer any virtual damages?

Hello Klaus,
no, could not see any damages on the AC. Even I have the settings in FS9 for showing damages. The landing rate was not too high I guess. Very nice to see that it makes a different flying below MLW on GS ILS or with more. In my case i tried it with about 170.000 lbs. The developer of this particular Flight Dymnamics has done a very good work in this case.
Thank you for your respond. Thinking about some more Videos representing more the technical side of the HGJ Aircraft and showing the differnt behaviors in different situations.
Regards
Michael

Nice video. When we test we use MGTOW and MLW to make sure we get the FDE to behave as close as possible at the extreme weights. I did notice that your approach speed seemed a bit low for that weight. Did you check the FE dialog, or click on the ASI to get the proper Vref? The approach should be flown at Vref+10. That might help with some of the control issues you were seeing. Lose the glass HSI...it's much more fun to fly these old birds using the original nav equipment....no magenta lines!   Mike |

Prefer to discuss these sorts of details on "Tech Support" pages .... but anyway ....  Landing weight "WILL" affect how these B727's (and any other simulation) fly the approach up until the actual landing. My recommendation is .... watch the the approach to landing airspeed with full flaps, and gear, extended. Desirerably .... landings shouldn't be undertaken with in excess of 20% (per tank) total remaining fuel .... at the very most .... and which should then see these B727's well below MLW. Depending on actual weight .... this (the approach to landing airspeed) shouldn't exceed around 135 - 130 KIAS "with full flaps and gear extended" .... and which, by the time of power reduction during the flare,for the actual landing just prior to touchdown, will/should also aid countering any tendency for these simulations to want to float either during the approach or prior to landing .... to ensure an actual touchdown speed of around 125 KIAS.

ENGINE # 2 first .... followed by ENGINES # 3, and # 1 .... is the order of startup recommended within the "ENGINE STARTUP" tutororial included within my above-linked forum based "B727 PANELS - INSTALLATION & HANDLING NOTES" manual .... but .... unless a particular engine must be started first (as "is the case" with tour DC-8 and B707 simulations in order to generate power for other systems or provide bleed air to start for the remaining engines) .... the actual order of engine startup can vary among airlines.
In FS, and for these B727 simulations though, the engines may be started "in any order of preference".
If using the FS auto-startup procedure (and which may apply in FSX by default .... since these panels are FSX portable, but, teir FS2004 prescribed engine startup procedure may not work), then, FS will always apply it's default engine startup order of ENGINE # 1, # 2, and then # 3.

Nice video Michael. I thought your approach speed was fairly good and your landing attitude was quite normal and did not show an eccessive tail down tendency. Perhaps excecuting the flare a bit sooner would have achieved a lower touchdown rate of descent.

Thank you all for your answers and inputs. This inputs I will use for my next flights even for more enjoyment with this 727 Simulations. Mark is right with the low landing speed, since this AC has a very good flare attitude by pitching arround 4,1 Degrees it beheaves nearly a sailing plane. So I am very happy, too say it again, with the Flight Dynamics, due to the fact I nearly ajust other FDs for my personal needs and feelings. So I know what a good job has been done for this simulation. mike: you are right withe the glass instruments. I use it mainly for longer distance flights and it a help finding the correct Sid and Stars in differt areas of the world instead of using a lot of charts! But ! Instate I try to fly only yoke and using the AP for Alt hold only. Departures and landing manuel! ISG Instruments is good Alternate und does not effect the Flight Dynamics of the Simulation as far as my experiance is. mark: Thank you for the engine start sequence. Like the simulated sequences in the DC8 series too. Herman: on short final I had to put some more on trust just to reach the Rwy correct, short before the tail pushes the AC down. But trust and pitch had resolved. Regards Michael |
