Bruce, and B,
Thanks for the AC-520 info. Sir Barry was kind enough to send me a scan of
the manual pages he has, but there are no references to performance speeds
really -- just limitations.
I appreciate your noting the performance speeds -- such as they are.
My interest is a little bit historical and a little bit practical. The
last time I was in an AC-520 was about 1993 so I had no recollection of the
performance speeds and of course, I was asked to fact check an article for a
publication.
Beyond that smallish task, I have always found the AC-520 manual ...
charming. Historically, this manual was prepared before V-speeds were used
as nomenclature. It's always been a trick developing a more modern check
list for the early Commanders and ferreting out V speeds from the manuals.
Speeds such as "best climb speed" are used, but how do they relate to our
post 1976 (when GAMA standardized aircraft manuals and used V speeds)
concepts. Is "best climb speed" Vy, Vyse, Vx or Vxse?
>From that perspective, if you ever have the chance to look at the evolution
of Aero Commander manuals, start with the AC-520 with its sparse 4 pages and
work your way up to the AC-685 where there are as many performance graphs
(and V-speeds!) as a Boeing.
Yes, if anyone would like to scan their AC-520 manual, let's take a look!
Happy New Year, Commanders!

Nowhere, just busier than I want to be, I'm still in St. George, UT. I had a
complete computer crash a year or so ago and lost the Chat link, just
getting a little more back to normal now.

| Subject: | 560 operating speeds |
For those wanting to compare the 520 to the 560, my 560's serial # 173
stats are:
All speeds TIAS
Never Exceed Speed (Vne) 270 mph
Maximum Structural Crusing Speed 200 mph
Maneuvering Speed 156 mph
Maximum Flap Extension Speed 125 mph
Max Gear Extension/Extended Speed 180 mph
Max Speed for 1/2 Flaps 150 mph
Minimum Control Speed * 80 mph
Best Angle of Climb (Vx) 110 mph
Maximum Performance Climb* 75 mph "don't know how this
makes sense!"
Best Rate of Climb (Vy) 135 mph
The 'Engine-Out' drill calls for Full Power on Operating Engine,
maintain heading and keep the airspeed between 95 - 100 mph (Vse)
For anyone out there looking for clean 560 mine's up for sale. Both
engines 0 SMOH (gearboxes tight) Props only 1 hour but out of calendar,
modern panel w/ King KX 155's (1 w/ GS), King Audio Panel & Txpr,
Northstar Loran, Dual Pilot/Co-Pilot instruments. New Tires, Paint '7'
Interior '7'.
This ship's been gone over with a fine tooth comb. It's just me and the
wife, time to find a Cessna Cardinal again!
