Dornier Do 27
After WWII, Dr. Claudius Dornier began collaborating with the Spanish company CASA. Initially, he produced the Do 25, to meet a specification of the Spanish Air Ministry for a STOL light transport. Returning to Germany, Dornier then produced the Do 27, a development of the Do 25, which first flew in 1955. The Do 27 entered production in 1956, becoming the first plane to enter production in Germany since the end of the war. It was a high-winged monoplane with a wraparound windscreen and a strutless wing structure, allowing easy access to the cabin doors for passengers and cargo. It became very popular, with some 628 aircraft being produced before 1965. The Do 27 was used by the West German Republic, Switzerland, Belgium, Congo, Israel, Nigeria, Portugal, Sweden, South Africa, Turkey, Belize, Rwanda and Sudan.
The Do 27 burns 10 gallons of aviation fuel per hour at routine usage. A full load of fuel costs $11.60. Historical range is 684 miles.

Design Notes:
Historical wing area was 209 sf. The design purchases 60-gallon fuel tanks; the historical volume is listed above. Chassis weight, cost and HPs were divided by 2 to reflect a civilian design and reduce design weight. Design loaded weight was increased 1% to the historical. Design aSpeed was 149 mph. Performance calculations were based on historical values for wing area and loaded weight.

Variants:
The Do 27B featured dual controls.
The A-1 to A-4 subvariants different in their maximum rated weights. Similarly, there were B-1 and B-2 subvariants.
The Do 27H featured a 254-kW engine and as three-bladed (rather than two-bladed) propeller.
The Do 27Q-5 features provisions for quick conversion to an air ambulance, glider tug, photo surveillance, or training roles. An -R version could be adapted for agricultural and forest dusting.
The Do 27S was a single floatplane prototype.
The Do 27T was a single turboprop prototype.
