The file contains more information, probably the digital camera or scanner used to create or digitize it. It was a fixed-gear, low-wing tail-puller with a crew seated in a tandem of two. When production ended in 1944, approximately 11,537 Valians were built. The BT-13 was the most used training aircraft in World War II. It was flown by American pilots who were transitioning from basic trainers like the PT-19 to more advanced trainers like the AT-6. It was more complex than the primary trainer and required support for two-way radios, landing flaps, and attitude and pitch control. Its pilots dubbed the BT-13 the "Vultee Vibrator" because of its most prominent feature, its tendency to vibrate violently when approaching normal speed.
BT-13 is available for Saturday rides at Merrill Field in Anchorage from May through October. The tandem seats in the back offer incredible views of Anchorage and the Chugach Mountains—perhaps even Denali on a clear day.
The BT-13 was powered by either the Pratt & Whitney R-985-AN-1 or the Wright R-975-11. Both engines produce 450 hp. This allows the Valiant to be an easy transition aircraft from the basic trainers of the day like the PT-17 or PT-22 to the more sophisticated AT-6 Texans or Harvards (like ours!)
After World War II, most Valiants were scrapped, but some were sold to private owners. Currently less than 50 are navigable and we are the only known BT13 in Alaska.

Vultee Bt 13 Valiant By Daniel Wales Images On Deviantart
The Vultee BT-13 Valiant is an American World War II basic training aircraft (category between basic and advanced) built by Vultee Aircraft for the US Army Air Corps and later the US Army Air Forces. A later variant of the BT-13 in USAAC/USAAF service was known as the BT-15 Valiant, while the US Navy's identical version was known as the SNV and was used to train naval aviators for the US Navy and its sister service. . , the US Marine Corps and the US Coast Guard.
The Vultee BT-13 was the primary trainer for most American pilots during World War II. This was the second phase of a three-phase pilot training program. After initial training on the PT-13, PT-17 or PT-19 trainer, the stud pilot moved to the more sophisticated Vultee for further flight training. The BT-13 had a more powerful engine and was faster and heavier than the main trainer. He asked the stud pilot to use two-way radio communication with the ground and use the landing flaps with a standard Hamilton two-position steerable propeller (or, more commonly, a constant-speed propeller).
). However, it had no retractable landing gear or hydraulic system. The valves were operated by a crank and cable system. It was nicknamed the "Vibrator Vultee" by its pilots.
Due to demand for this aircraft and others using the same Pratt & Whitney engine, some were fitted with Wright engines of similar size and power built in 1941-42. Wright's manned plane was called the BT-15.

The Navy adopted the P&W-powered aircraft as its primary basic trainer, designating it SNV. BT-13 production exceeded all other basic trainers (BTs) produced.
In 1938, Vultee chief designer Richard Palmer began designing a single-engine fighter. At the time, the Army Air Corps submitted a request for a high-level trainer, promising a major order if selected. Palmer adapted his design concept from a fighter to an advanced trainer, resulting in the V-51 prototype.
As a low wing cantilever monoplane in all metal construction with fabric covered control surfaces. It was powered by a 600 hp (450 kW) Pratt & Whitney R-1340-S3H1-G Wasp radial engine driving a two-blade variable-pitch metal propeller. It had an enclosed cockpit for the instructor with studs, an integrated wing fuel tank and a hydraulic system to control the flaps and retractable main landing gear.
The V-51 entered the USAAC competition as the BC-51 in May 1939. Instead, the USAAC selected the North American BC-2 for the competition, but also purchased a BC-51 prototype for further study, designating it the BC-51. 3 Palmer improved his design, resulting in the VF-54, with the goal of selling the trainer in other countries. It used the same basic airframe as the VF-51, but was equipped with a lower gyne. However, no export sales will come from this proposal.

The V-54 was further improved, resulting in the VF-54A, with fixed fixed landing gear, manually operated landing flaps, and the Pratt & Whitney R-985-T3B Wasp Jr. with a radial power of 450 hp (340 kW). In this form it was offered to the USAAC and in August 1939 the type was ordered as the BT-13. The first order was for 300 aircraft with Pratt & Whitney R-985-25 radials. The first aircraft was delivered to the USAAC in June 1940.
The BT-13A produced up to 7,037 aircraft and differs only in the replacement of the Pratt & Whitney R-985-AN-1 radial engine and the removal of the gearbox. 1 125 units were produced with the designation BT-13B; they differ from the A model by replacing the 12v electrical system with a 24v system.
Due to industry-wide demand for the Pratt & Whitney R-985 engine, a total of 1,263 units were produced, incorporating the equally powerful Wright R-975-11 engine. USAAC approved them as BT-15.
The US Navy also ordered 1,150 BT-13A models under the SNV-1 designation. It also ordered another 650 SNV-2 units based on the BT-13B.

Once in service, the aircraft quickly earned its nickname "The Vibrator". There are several explanations for this nickname. 1: Because it had the tdcy shuddering quite violently when approaching normal speed. 2. During more adventurous maneuvers, the canopy vibrates. 3. As the plane took off, the windows on the ground shook. 4. The two-position propeller had an irritating vibration at high pitch. The BT-13 served its purpose well. It and its successors were an unforgiving aircraft to fly, but they were also very agile. So the BT-13 made a good aircraft that helped hundreds of pilots move up to advanced trainers and fighters they hadn't yet learned.
The BT-13 was not without its flaws. Some were built with plywood tail cones and joists that didn't always stay firmly aligned with the plane.
The tail was held in place by only three bolts, and after several in-flight failures, the Navy restricted the aircraft to aerobatics and violet maneuvers. The Navy declared the SNV obsolete in May 1945 and replaced it with the SNJ (T-6) in the basic training role. The Army also replaced the BT-13 with the AT-6 before the end of the war.
After World War II, almost everything was sold as surplus for a few hundred dollars. Many people bought simply to get genies that were fitted to surplus biplanes (such as Stearmans) to replace less powerful genies used as farm rigs. BT frameworks have been abandoned. Several others were converted to multi-passenger civilian aircraft; one "Viceroy" and at least two others from different companies. Today there are some "BT" (including BT-13, BT-15
