bc12d pilots op handbook

[ak t cart]

anyone have a good copy of operating limts, performance specifications charts, short field/ takeoff distance charts, all that stuff pertinant to the t-cart specifically. thanks.

Re: bc12d pilots op handbook

I think the best source is the TCDS.

Look it up on the www.faa.gov site

try ESSCO aircraft manuals, they have most of older manuals. Tim

i am looking for more info than the a 696.

Well, you might need to conduct a number of test flights and generate the data specific to your plane. Back 70 years ago there just wasn't that much detail required and if you are hoping to find an extensive list of v speeds beyond what is on 696 they are probably something someone came up with and may or may not apply to your plane since each one is a bit different from the other. For instance, our BC-12D stalls at about 49 kts indicated. I read of people on this forum using approach speeds slower than that. If you try it in this plane it will give you a surprize. (the airspeed indicator has been calibrated) Anyway, find what speeds work best in your airplane and use them.

Dear AK T Cart,

I have the Owner's Manual, Maintenance Manual, and Sevice Manuals. None of them have any performance charts of any kind. I would guess that almost all of the operating information contained in them is on the TCDS.

The Maint. & Service Manuals obviously give info concerning where to grease what, how much to grease, etc. One nice thing is they tell you how to rig the washout in the wings. But none of them tell you how much distance you need to clear a 50' obstacle at a certain density altitude, or how many hours of endurance you will have at a given power setting.

If there is something specific you have a question about maybe someone on the list here can offer an answer.

Re: bc12d pilots op handbook

i had ordered a continental a and c series operators manual, and parts catalog. turns out the operators manual has a ton of useful info. recomended cruise, climb, economy cruise speeds. run up speeds. check lists for that specific engine, performance curves, altitude performance, inspections..a whole bunch of good stuff. i would definately recommend this manual to anyone who doenst have it. thanks for the replies, Logan

49 knots is 56 miles an hour. If your plane is truly stalling at 56 miles an hour there is something very very wrong. Perhaps you should cover the wings with fabric and dope

Did you calibrate your entire airspeed system or just the indicator? A perfectly calibrated indicator attached to a bad pitot-static system is obviously a suspect here.

Assuming your wings are not twisted (and twisted the wrong way at that), personally it is pretty hard to wrap my head around that high of a stall speed.

Sorry for the obvious/silly question, but do you have the wing root cover strap fairings installed?

Re: bc12d pilots op handbook

Yes we have all the parts installed including wing root fairings and so forth.

The instrument calibrations were required as part of the STC process for the O-200 and I don't know if they were calibrated in or out of the aircraft. Anyway, the plane flies fine. The cruise is about 85kts with a metal prop at2400 rpm. The plane doesn't have have negative dihedral or anything weird looking about it but I have never tried adjusting the wings or anything. I also haven't tried doing two way gps runs to verify the airspeeds but from the way it handles I think the airspeed is reading correctly. (you know, x fence posts per unit of time...) We fly our patterns at 70kts on downwind, 65kts on base and a 60kt final which is just a tad over 1.2 vso and it all seems to work out.
