By the time the 707 had entered service, Boeing realized the need for a shorter range aircraft intended primarily for domestic service. Over 70 possible configurations for this new aircraft were considered with Boeing finally selecting a design emphasizing commonality with the 707 and 720 to lower costs. However, the 727 departs from these designs by using a three-engine arrangement with al three located at the rear of the aircraft. The advantages of this arrangement include the reduction in structural requirements of the wing while promoting improved wing aerodynamics.
The 727 also incorporates thrust-reversing engines and an advanced flap system to reduce landing field length. Although the aircraft was even more economical to operate than initially anticipated, sales were somewhat disappointing in the early 1960s since many operators desired larger capacity aircraft. Boeing therefore with an enlarged 727, the727-200, capable of carrying up to 189 passengers or more fuel. Both the 727-100 and 727-200 models soon became best sellers, and a total of 1.832 airframes were completed when production ended in 1984. Boeing replaced the design with the more advanced 757.
The Boeing 727 is equipped with the latest communications and navigation technology as well as systems compliant with the recommendations of the International Civil Aviation Authority. These systems include:
1. GPS (Global Positioning System)
2. ANS (Area Navigation System)
3. ACAS II (Anti Collision Air-traffic System)
4. CAT- II approach (Category)
5. RVSM (Reduce Vertical Separation Minimum)
