Captains,

I spent this weekend testing the wonderfull 707, even flying her in an online-event on the IVAO network from Munich to Frankfurt. I collected some usefull information on flying the old lady from various sources (CS manual, AVSIM, etc.) As a result I would like to share some of the expierience with all of you.

Please note: these data are not from an official source but a destillation of my personal opinion, public information and so on. Please feel free to ignore it and find a better solution-it's just my personal way to treat this old lady kindly.

200      143      110      112      113      118      131      225

flaps schedule and speed bug settings for approach:

Vfl50=Vth = treshold speed (see chart above), approximately Vstall50*1,3

Correction: headwind component+1/2 gust component, in total max. 20 knots

Vapp = Vth + 5 + wind/gust correction

Flaps      50      40      25      14      0
Speed      Vapp      Vapp+10      ...+20      ...+30      ...+40

Bug 1: Vapp+50, Bug 2 Vapp+20, Bug 3 Vapp



Precision-(ILS-) approach:

-LOC intercept: max. Vapp+50
-2 dots below G/S Vapp+20, Flap 25
-1 dot below G/S gear down (for high speed approaches when passing 1500 ft AFE)
-1000 ft AFE Vapp, Flap 50

non-precision-approach, visual, circling:

-reach final fix with Vapp+20, flap 25, gear down
-reach 1000 ft AFE with Vapp, flap full, stabilized, landing checklist complete

missed approach:

-set thrust, at positive rate gear up, flaps 25, climb at Vapp+20, when clear of obstacles or passing 800 ft. AFE flap 14, accelleration to establish climb speed, fully retract flaps


Happy landings

Stefan

Captains,

unforunately, the table I created is not shown in the correct format-the first two lines are the headline for the respective columns. I don't know how to edit my post, perhaps admin can help.

Thanks

Stefan

Looks better now!
