HPT-32 Deepak
The HAL HPT-32 Deepak ("lamp" in Sanskrit) is an Indian prop-driven primary trainer manufactured by Hindustan Aeronautics Limited. It has two seats in side-by-side configuration. Operational history The Deepak is used for primary training, observation, liaison and target towing. When it flies upside-down fuel flows from a collector tank in the fuselage and the inverted flight is limited to 1 min. Deepak has a theoretical glide ratio of 8.5:1. The IAF and HAL are looking into new safety systems such as Ballistic Recovery Systems to enable it to descend safely in the event of an engine failure. On 16 May 2010 the IAF cleared the installation of a parachute recovery system. The HPT-32 aircraft has been replaced by the Pilatus PC-7 Mk II in the IAF, as its workhorse as a Basic Trainer Aircraft (BTA) in 2013. Accidents In 17 Deepak crashes so far, 19 pilots have died. The Comptroller and Auditor General (CAG) of India has been reported as saying the aircraft is "technologically ou ...

Primary Trainer
A trainer is a class of aircraft designed specifically to facilitate flight training of pilots and aircrews. The use of a dedicated trainer aircraft with additional safety features—such as tandem flight controls, forgiving flight characteristics and a simplified cockpit arrangement—allows pilots-in-training to safely advance their skills in a more forgiving aircraft. Civilian pilots are normally trained in a light aircraft, with two or more seats to allow for a student and instructor. Tandem and side by side The two seating configurations for trainer aircraft are: pilot and instructor side by side, or in tandem, usually with the pilot in front and the instructor behind. The side-by-side seating configuration has the advantage that pilot and instructor can see each other's actions, allowing the pilot to learn from the instructor and the instructor to correct the student pilot. The tandem configuration has the advantage of being closer to the normal working environment that ...

Allison 250
The Allison Model 250, now known as the Rolls-Royce M250, (US military designations T63 and T703) is a highly successful turboshaft engine family, originally developed by the Allison Engine Company in the early 1960s. The Model 250 has been produced by Rolls-Royce since it acquired Allison in 1995. Development In 1958, the Detroit Diesel Allison division of General Motors was chosen by the US Army to develop a new light turbine engine to power a "Light Observation Aircraft" (LOA), to replace the Cessna O-1A Bird Dog. At this stage the US Army was unsure whether to have a fixed- or rotary-wing aircraft, so Allison was instructed to consider both applications. Design studies undertaken considered a wide range of possible mechanical configurations for the turboprop/turboshaft. These studies culminated in the testing of the first prototype engine, designated YT63-A-3, in April 1959. In 1960, the US Army settled for a rotary wing platform. The YT63-A-3 first flew in a variant of t ...

1970s Indian Military Trainer Aircraft
Year 197 ( CXCVII) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Magius and Rufinus (or, less frequently, year 950 '' Ab urbe condita''). The denomination 197 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

HAL HTT-40
The HAL HTT-40 (Hindustan Turbo Trainer-40) is an Indian training aircraft designed and built by Hindustan Aeronautics Limited (HAL). It will replace the Indian Air Force's retired HPT-32 Deepak as a basic trainer. Design and development The HTT-40 is an all-metal, tandem seat aircraft powered by a turboprop engine. In early 2012 the company forecast building 106 examples. By the middle of 2012 the aircraft's future was in doubt as the Indian Air Force ordered 75 Pilatus PC-7 Mk IIs to fill the role envisioned for the HTT-40. In September 2012 the Air Force indicated that it had formally rejected the HTT-40 for service based on its cost per aircraft being double that of the PC-7 Mk II, a proven aircraft, already in service worldwide. An MoD official noted, "We would be willing to pay higher rates to build indigenous capability in strategic defence equipment. But can HAL argue that the capability to build basic trainers is strategically vital At that time HAL did not confi ...

Pilatus PC-7
The Pilatus PC-7 Turbo Trainer is a low-wing tandem-seat training aircraft designed and manufactured by Pilatus Aircraft of Switzerland. The aircraft is capable of all basic training functions including aerobatics, instrument, tactical and night flying. The PC-7 was developed from the preceding Pilatus P-3, largely differing by the adoption of a turboprop engine, a bubble canopy, and a new one-piece wing. Introduced during the 1970s, it has since developed a sizable presence of the global trainer market. The type has been adopted by in excess of 20 air forces as their ab initio trainer, as well as multiple civilian operators. Over one million hours have reportedly been flown by PC-7s worldwide. In addition to training operations, some aircraft are armed and have been used for combat missions by several customers, including Chad, Iran, and Mexico, often in violation of the relevant export agreement between the customer and the Swiss government. An improved model of the aircraf ...

Ballistic Recovery Systems
Ballistic Recovery Systems, Inc., doing business as BRS Aerospace (and commonly referred to as simply BRS), is a manufacturer of aircraft ballistic parachutes. The company was formed in 1980 by Boris Popov of Saint Paul, Minnesota, after he survived a fall in a partially collapsed hang glider in 1975. As a result, Popov invented a parachute system that could lower an entire light aircraft to the ground in the event of loss of control, failure of the aircraft structure, or other in-flight emergencies. Popov was granted a U.S. patent on 26 August 1986 for the so-called Ballistic Recovery System (BRS) - patent US 4607814 A. The company has two divisions: BRS Aviation and BRS Defense. History BRS was founded in 1980 and introduced its first parachute model two years later in 1982, with focus on the ultralight aircraft market. The company recorded its first successful aircraft and crew recovery in 1983: Jay Tipton of Colorado. In 1998, BRS collaborated with Cirrus Design (now ca ...
