Your stall speeds, versus flap settings?

Curious that the 182 has 43kt for both! What does that mean?

From “Flight Planning Guide Citation 560 Encore”:

STALL SPEEDS
Zero Angle of Bank, Landing Gear Up or Down, KCAS
Stall Speeds
----------------------------------- Flap Position ------------------------------------
Weight (lb) Full 15° 7° Up
16,630 86 91 95 97
16,000 84 89 93 95
15,500 83 88 92 94
14,500 81 85 89 91
13,500 78 82 86 88
12,500 75 79 83 85
11,500 72 76 79 81
10,500 69 73 76 78

Normal operation is to always land with full flaps. Everything else are abnormal/emergency procedures.

The interesting figure is not the IAS but the CAS. The pitot-static system error can differ substantially with and without flaps.

E.g. for a C172S:

Vs: (0° flaps): 48 KIAS, 53 KCAS.
Vs0: (30° flaps): 40 KIAS, 48 KCAS.

In this particular case the IAS difference is 60% greater than the CAS difference, but it could just as well be the other way around.

I am really confused as to the point of this thread.

You must be taking your life in your hands every time you fly!
