b200 king air performance

[Sarcs]

A true Cadillac of the skies, ie they handled beautifully with all the trim wheels, radio stack etc all in the right place but they were a bit of guzzler fuel-wise. As a result you were always recalculating fuel and over long sectors with adverse wx at destination you'd be sweating on it a fair bit and playing with levels, requesting blocks etc trying to milk the best combination of range versus endurance. The best fuel flow I'd ever seen in a B200 was 360lb/hr, that was achieved at FL340 and LRC. The aircraft was a B200SE fairly new and fully kitted out with Raisbeck mod, this aircraft use to TAS at 280kts and the vsi hardly dipped below a 1000ft/min up to about FL280.
Yeah the Super Kingair a trully classic pilot's aircraft....!!

Pfft.

Morno, stop bragging about your King Air time and just look after those onions, orright?


520!!

I don't vouch for the accuracy of this statement, but I was once told the King Air wing outboard of the engines is a Beech Baron wing, with a "filler" wing between the King Air engines. I would be very surprised if that were the case, however there is a remarkable similarity.

It is true that the King Air grew out of the Beech Queen Air and the King Air 100 looks remarkably similar to the Queen Air.

[Howard Hughes]

You are correct Tail Wheel, on both counts!
I understand the outboard section of the Kingair and the Baron use exactly the same NACA aerofoil design...

Wow, with all that excitment, and all those years ago, you actually still remember the RVS NOT READY light

You didn't mention it, but I hope you remembered to put the props into the high RPM position as this is the requirement for reverse being available, not weight on the undercarriage

Sorry, hate to be picky

[morno]

It's ok 520, the onions are doing fine. Perhaps if you paid them some onion support, they'd be doing even better, .

Props high rpm is required for max reverse. (As is cond lever to high idle)

Reverse is still available with less than full fine set however, it just won't be max reverse.

cheers

[OZBUSDRIVER]

I guess I can put that down to the sands of time

RE: Windshield heat

226 KIAS is the max speed for guaranteed ice prevention. You can go above that but, you might just get ice.

Vne btw is 259/0.52 for the B200, and 269/0.48 for the earlier 200's. Was the windscreen beefed-up along the way here? The B200 does run an extra 1/2 psid!?!?!

Does anyone have any ideas on the cause for the 140kt minimum in icing conditions? Is it true that this relates to the possibility of ice forming on the unprotected undersides at the higher AOA's??

[TwoHundred]

Any slower than 140kt in icing conditions and it will accumulate ice under the wing, rather than on the leading edge where it can be booted off.

I vaguely remember something about a mechanical linkage from the throttle levers to a cast iron 'block' that could crack if the throttle levers were moved into reverse without the prop levers in high RPM (max reverse RPM is only 1900 RPM controlled by the fuel topping governor to prevent the props from coming 'back on speed)

(As is cond lever to high idle)

I disagree with this though. Max reverse is at 83% N1. You can do this from 'Low Idle' which is 52% N1. It is just that you will reach 83% in reverse operations quicker if the condition levers were at high idle of 70% N1

The RVS NOT READY caution annunciator is a result of the prop levers not being in the High RPM position with the landing gear extended. This suggests to me that until you have meet all the coditions ie; gear down and props max, you will not achieve the correct reverse operation.

We could of course be comparing different models

[Reverseflowkeroburna]

Thanks 200, I suspected it was along those lines or the bottom of the fuse collecting it due to the higher body angle. It is however interesting that no other aircraft has anything similiar specified......or at least that I know of!

[TwoHundred]

Crikeys Monopole, i might have to get the book out

• cast iron block. Sounds sus to me
• max reverse prop prm 1900. Agreed
• max N1 in reverse 83%. Agreed

And your conclusion that max reverse will ocurr earlier/quicker if you have high idle set sounds good also.

So for maximum reverse effectiveness - set high idle and high RPM right?
