de Havilland Beaver

The de Havilland Beaver is a high wing monoplane powered by a single radial engine that was produced to take off and land in short distances while equipped with heavy loads and optional floats. The design can withstand the rigors of sub zero temperatures and less than perfect landings on unimproved air strips, ice, snow, or choppy waters.

The de Havilland Beaver first flew in 1947 with production continuing through 1967. A total of 1,692 were produced of which some 718 were sold throughout the world. The remainder were purchased by the United States government for use by their army, navy, and air forces. The airplane was even used by the U.S. as a utility transport over Korea during the Korean War. Several hundred de Havilland Beaver aircraft continue to fly today.

The de Havilland Beaver has a one ton load capacity, even when equipped with floats. Its rear doors are large enough for easy loading and unloading of 55 gallon drums. It is a true workhorse.

Three fuselage fuel tanks, with a total capacity of some 95 gals., are located in the bottom front of the airplane. This makes for easy refueling. The wing tanks of the de Havilland Beaver hold an additional 46 gals. of fuel. When flying the de Havilland Beaver, extra attention must be paid as fuel is consumed in order to keep the airplane properly balanced.

Cold starting the radial engine is a bit more involved than with a conventional engine. To prevent locking that can result from the pooling of oil, the propeller is hand turned several times. Once started, the engine is run at idle for twelve or so minutes to make sure its oil supply and total mass is properly warmed.

Throttle management during take off acceleration is necessary so as not to build up excessive manifold pressure. This is a relatively large, heavy, single engine airplane, and while it will not get into the air as quickly as a lighter airplane, its short take off, especially when fully loaded, is impressive. The flaps of the de Havilland Beaver operate in conjunction with its ailerons to help produce exceptional lift.

Although the de Havilland Beaver has a rather large side profile, cross wind landings and take offs are not difficult for experienced pilots. The controls are not heavy as one would expect, and are pleasant to handle. However, no one could ever say that the de Havilland Beaver is quick to respond to control inputs.

The radial engine of the de Havilland Beaver and overall bulk produces lots of drag. Landings are made with the nose down and extra attention paid to speed on final. Bringing the nose up, even under full power, will just make the airplane mush. To regain altitude, the stick must first be moved forward. So long as the limitations of the airplane are observed, landings are easy.

In 1964 a turbine engine de Havilland Beaver was produced. Its engine had about 125 more h.p. than the standard radial engine and the airplane was some two feet longer. However, only 60 were built.

A total of some 1,657 de Havilland Beaver aircraft of all types were built before production ended in 1967.
