				Gentlemen!
   
  I haven't been around an AC-520 since the last decade of the last millennium.
   
  Can anyone give me a list of V-speeds from the AFM?
  
 I realize the V-speed nomenclature wasn't used when the manual (what -- all 4 pages?) was written, but if someone can list the performance speeds, I'd greatly appreciate it.
   
  Thanks in advance,
   
  Wing Commander Gordon

				Wing Commander,V Speeds?  Manual?I was told to go full power and to pull back when the airspeed was in the green arc.  Gear up and go for Blue line.
 What more do you need?
 
 Kick tire, light the fire, and go like the wind?

				Hello Wing Commander!
   
  I have a Model 520 Flight Manual. I'm going to scan a  couple of pages and Email them to you.
   
  Are you about to fly a 520?
   
  Sincere Best Regards,
  Barry

				A few weirdnesses from the manual are:  
    
 “Best Rate of climb” in the manual is 96 miles per hour, as is blue line, but climb speed is specified at 123. I’ve notices it climbs better at 123. ( I just hold it low after clearing obstacles, until I get there when conditions permit. Like a Fouga, whose Vy is 200 mph. Of course, maybe its just more fun).  
 “landing approach” in the manual (not listed in the table) is 76 mph, well below Vmc (not that you *have*
   to hold speed above Vmc, btw, but it’s not normal practice these days.) BTW, it settles beautifully at that speed, but of course you need the runway made, and go-arounds would be an emergency procedure.  
    
 Gear 150 mph (That’s what I use except in emergency . I think its actually specified higher, 186mph.  ).  Flaps up to ½ 150mph  Flaps Full : 110mph.   Vne = 260 mph (I’ve actually seen pretty close to it twice, once when being called into a search from a logistics mission (the coast guard doesn’t hear speed two-fifteen we’ll be there in 10 minutes very often, though they have a few fast fixed wing A/C), once during a check ride).  
    
 It would be interesting to see how these relate to the 560s and 500s, which should be aerodynamically similar. In particular I think the specified Vx and Vy in the manual  are just plain wrong. If there was a big variance with the other 5-series that would support the idea.  
    
 As for the rest, I can get them from the plane today and list them (and confirm these), but is your interest historical or practical?

				I have an original 520 maintainance manual.  brownish  in color with gold embossed letters and emblems.  Anyway, if needed, let me know I can scan and send whatever u may need.

  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!
   
  Wing Commander Gordon

				This brings up the question of what the spec’ed  speeds are for the 560’s and 500s. It would be very interesting to compare.

 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.

 It would be interesting to see how these relate to the 560s and 500s, which should be aerodynamically similar. In particular I think the specified Vx and Vy in the manual  are just plain wrong. If there was a big variance with the other 5-series that would support the idea.  
    
 As for the rest, I can get them from the plane today and list them (and confirm these), but is your interest historical or practical?   |

  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.
