1977 C414 Ram VI perf data

[moabmic]

Does anyone have or know where to get the perf data for a 1977 Ram VI Cessna 414 (tip tanks FIKI)? Or could someone calculate a 85 degree day takeoff at gross (6765) and at 5700 out of Kaej which is 7900' MSL with a 8300' runway?

Thanks!

Used to fly a RAM IV, FIKI but no tip tanks, but my AFM copy doesn't have the RAM supplements...here's the stuff from the straight 414A...6000 ft and 86 degrees F, just to be lazy.

Two-engine takeoff to 50 ft: 4210
A-Stop: 6320
A-Go: 8190

SE ROC (cleaned up): 100 fpm
Engine windmilling: subtract 400 fpm
Gear Down: subtract 350 fpm
(that's an initial descent rate of 650 fpm when the engine fails)

Fly safe!

Thanks! With the Ram it will hopefully do a bit better but it seems to be workable for now. I'm hoping that I'm a few weeks away from closing on this '77 414. I wish it were an 414A but that's way too spendy compared to the gains....

Great thinking!

(Unless you find yourself in a single engine situation)

414 ? I think you have the right numbers in the wrong order, I think the only Cessna with props for that field is called the CE-441, good luck, that 414 is sick at sea level, and don't collect any ice on the airframe going in there, yikes, save the money on that IFR GPS and by a real airplane, no I'm not joking. And yes I have plenty of experience operating that type aircraft in a certain airport in the SW flying the ditch, the only people I know that are still alive after losing an engine anywhere just after takeoff are those that landed straight ahead.

Are you sure that a strait 414 has a gross weight of 6765? The 402B I fly, which is basically an unpressurized 414 only has a Max Gross of 6300lbs. The 402C (unpressurized 414A) has a Max gross of 6850lbs. I really like the 402, the C is obviously far superior to the B, but the B is still a very nice plane. It has decent performance as long as both engines are running, but single engine performance is very poor. They also don't do too bad in the ice, I fly em up here in the great lakes year round and have yet to have a day ice would stop me from going up.

The C model really does have ALOT better performance, that extra 8 feet of wing REALLY makes a big difference. You get an extra 550lbs gross weight which is basically all translated into useful load since the C doesn't weight much more than the B, and it flies much better at gross than the B. It's also about 10kts faster and carries an extra 43 gallons of gas standard. If you can afford the 414A your really making a step up in capability.

Red, don't doubt what you say about the ice where you live, it's a MUCH different animal in the mountains.

That doesn't suprise me, I've noticed that ice is diffferent in different regions of the country.
