In several ways the latest Cougar differs from one other two white twins

On gross and with one enthusiast feathered, a Cougar commonly climb up 50 fpm on 4,250 base, limit, under simple criteria

Rather than that have lapped and riveted skins, The latest Cougar's are bonded to the bulkheads and ribs forming the fuselage, empennage and you will wings The result is a good slicker airframe, a significantly convenient looks and you can, as outlined by customers, a lot fewer difficulties with corrosion. On the other hand, the reduced servings of cabin fuselage are made from good however, smaller aluminum honeycomb. However the greatest differences are, however, the fresh Cougar's 160-horsepower Lycoming 0-320 motors. New Duchess and you can Seminole possess 180-horsepower O-360s. They likewise have stop-spinning propellers, and this take away the crucial-system bugbear. Both of the brand new Cougar's props turn clockwise; therefore, a pilot officially have to have a more dating in Chula Vista challenging big date talking about a failure of one's left (critical) system, given that best prop takes a larger bite and you will produces more asymmetric push as compared to leftover.

The new Cougar, Duchess and you will Seminole are much similar in one single area: single-motor results. Most of the three perform miserably shortly after dropping an engine on the takeoff. The fresh Cougar POH demonstrates that, at sea-level for the a basic go out at their gross pounds off step three,800 lbs, the newest flat usually go up around two hundred fpm using one engine, when your pilot do what you proper (cobs the great engine, feathers the latest crappy, provides the tools and you can flaps up, and so on).

Within the criteria intricate more than, the latest planes commonly challenge right up just 140 legs each kilometer they excursion along the soil. Through its 180-hp motors, the brand new Duchess and you may Seminole try not to would best. Its unmarried-system rates-of-rise and you may go up gradients try, respectively: 235 fpm and 166 foot for each distance; and you may 217 fpm and 148 feet for each and every distance. You to definitely meager abilities will come not as much as practical requirements; dump a system in any of your airplanes to the takeoff from Denver to the an attractive big date, therefore the quantity likely would have bad cues before her or him.

Compared, the latest solitary-motor services ceilings of your own Duchess and you can Seminole is actually six,170 base and you can 4,a hundred legs, respectively. A beneficial Ways However it does not succeed using one motor, this new Cougar possess an effective handle features,due to an enormous the quantity into airplane's huge tail. Vmca, minimal manage rates with an engine out, try 61 knots-a couple of tangles below appears rates that have getting tools and you may flaps extended. Stands strips towards the best sides of altered laminar-flow NACA 63A-415 wing result in the side origins so you can appears long before the latest hps

In the event that a two hundred-fpm rate of climb cannot voice all that crappy, think about the Cougar's single-system abilities another way: which is, when it comes to climb up gradient

We were provided a demonstration of your own Cougar's docile manners because of the Gil Stout of Flying Tigers inside Marietta, Pa., a former Grumman broker whoever specialties nevertheless tend to be Cougar conversion and you may solution. In the step 1,five hundred ft to your an enjoying go out, Stout closed the best motor, feathered the new prop and made good cuatro

training grow to be the latest dry motor. No problem. Following, the guy pulled this new nose way up. The new stands buzzer shrieked since the Cougar shook including. well, a wet cat. One to side fell, then the almost every other; however, Stout were able to pick them up towards the rudder each time. At the same time, we were sinking around five-hundred fpm; but, from the trial, the fresh airplane never ever gave any indication that it was going to do something freaky. Because of restricted elevator travel, it is sometimes complicated so you can stands a good Cougar without abrupt manage deflection. There was a trade-off, not. According to citizens, good pilot to make an electricity regarding landing with complete flaps when you look at the an airplane stacked for the the leading chairs. pass cg restrict is use up all your lift power throughout the flare and you will plunk down on all around three rims, particularly when airspeed try a tad too at the top of means.
