Introducing the Beechcraft King Air 360
Textron Aviation ushered in the next generation of its legendary King Air turboprop family on Tuesday with the introduction of the Beechcraft King Air 360/360ER. (dcnewsroom.blogspot.com) Daha Fazlası...Sort type: [Top] [Newest]
Really liked flying the KA from 'strips' in S. America. Mentioned "hard rice" back in the day; he had no idea what I was talking about!
They once planned a four engine King Air, it went like hell but only for 30 minutes. Kidding.
6000 hours King Air ( 90-100-200).
Vacuum came from the pneumatic system (no pump) on each engine, either engine could power the vacuum system through a venturi.
PT-6 is an example of excellence, bullet-proof. A joy to fly. 250 would be my choice for a personal aircraft.

My ground school instructor told a story about the King Air having only one vacuum pump. If that failed, you were toast, unless you could tell what the plane was doing by looking at the other instruments. His point was that a 'good pilot' should be able to read the instruments, if needed, and be able to see if they were climbing or descending. Work on your piloting skills. Know what the instruments are telling you.
But did some of the King Airs only have one pump?

King Airs have no vacuum pumps. jthyland, in his/her post, is correct.
Here are few words from my old King Air B200 Flight Manual:

SYSTEM DESCRIPTION AND LOCATION
CHAPTER 9 PNEUMATICS
Pneumatic and Vacuum Systems
Page 9-1
High-pressure bleed air regulated to 18 psi, supplies pressure for the surface deice system and the vacuum source (Figure 9-1). Vacuum for the flight instruments, pressurization controller, and surface deice originates through a venturi (bleed air ejector) which is exhausted overboard (Figure 9-2). One engine can supply sufficient bleed air for all associated systems. In addition, the brake deice system receives bleed air that is tapped off downstream of each instrument air valve
Engine bleed air is ducted from each engine to its respective L or R flow control unit mounted on the firewall. A pressure supply line tees off the engine bleed-air line forward of the firewall and flow control unit. This supply line contains pneumatic pressure to operate the surface deicer, rudder boost, door seal, brake deice (hot brakes) system hydraulic reservoir (BB1193 and after, including BB-1158 and 1167).
From the official FAA Hawker Beechcraft Corporation Beechcraft Model 200 and F90 MMEL
System 37, Vacuum/Pressure
2 systems provided.
1 systems may be inoperative provided that the aircraft is not operated in known or forecast icing conditions.
Both systems may be inoperative provided:
a)Affected Valve remains selected INSTR & ENVIR OFF,
b)Affected Valve is verified closed prior to each Takeoff, and
c)Aircraft is not operated in known or forecast icing conditions.

To see how easy it is to fly the King Air look up the Youtube video of the untrained guy who landed it in Florida after the pilot died.
I flew the -200 (C-12)when I was in the Army in the late '70's. Sweet, sweet flying airplane and very capable. The only downside I remember was trying to climb to a mid-level FL .with the engine ice vanes activated. Climb performance was not very impressive ;-) other than that I can't think of anything I didn't like about the C-12. Loved that airplane. Also flew the U-21 and U-21F. Good, dependable, rugged airplanes.
Epstein or Maxwell didn't kill themselves.
