Paf Celebrates Golden Jubilee of Defence Day
PAF CELEBRATES GOLDEN JUBILEE OF DEFENCE DAY Islamabad 06 September, 2015:- Defence Day of Pakistan was celebrated at all PAF Bases in a befitting manner. The year has been marked as the Golden Jubilee of 1965 war, when PAF vanquished a three times large Indian Air Force and wrote an epic of unmatched valor and sacrifice. The auspicious day was observed with a renewed pledge and determination to make “Fizaia” even more stronger and potent force to face any challenge. The day started with special Du’a and Quran Khawani for the Shahuda at all PAF Bases. A special feature of the day was the change of guards ceremony at the Mazar of Quaid-e-Azam in Karachi. Aviation Cadets from Pakistan Air Force Academy, Risalpur assumed guard duties at the Mazar to honour the Father of the Nation. On the occasion of Defence Day Air Chief Marshal Sohail Aman, Chief of the Air Staff, Pakistan Air Force said in his message, “We are a resilient nation, which has always proved its worth in difficult times, whether those were natural calamities or an imposed armed conflict, as in 1965. Though, we are a peace loving nation, but we know how to thwart the heinous attempts that disrupt our peaceful way of life and certainly, our strength is in this resolve. Today, let us re- pledge to make Pakistan a truly dynamic and prosperous country by firmly following the great Quaid’s golden principles of Unity, Faith and Discipline as our national ideals. On this occasion, I would like to assure you that Pakistan Air Force, with state-of-the-art equipment on its inventory and a highly capable workforce, is fully prepared to defend the aerial frontiers of its motherland”. -
Boeing 737 Postmaintenance Test Flight Encounters Uncommanded Roll-And-Yaw Oscillations
FLIGHT SAFETY FOUNDATION Accident Prevention Vol. 55 No. 5 For Everyone Concerned with the Safety of Flight May 1998 Boeing 737 Postmaintenance Test Flight Encounters Uncommanded Roll-and-yaw Oscillations Fluid leaking from the cabin onto the yaw-damper coupler in the electronic-and-equipment bay affected electronic signals transmitted to the yaw-damper actuator and caused a dutch-roll oscillation. FSF Editorial Staff On Oct. 22, 1995, a Boeing 737-236 Advanced was • “Sufficiently conductive contaminant paths in straight-and-level flight at Flight Level (FL) 200 between certain adjacent pins had affected the (20,000 feet), at an indicated airspeed of 290 knots phase and magnitude of the signals transmitted when roll-and-yaw oscillations began.

11ADOBL04 December 2010
11ADOBL04 December 2010 Use of rudder on Airbus A300-600/A310 (extracted from former FCOM Bulletin N°15/1 – Subject N°40) Reason for issue On February 8th, 2002, the National Transportation Safety Board (NTSB), in cooperation with the French Bureau d'Enquêtes et d'Analyses (BEA), issued recommendations that aircraft manufacturers re-emphasize the structural certification requirements for the rudder and vertical stabilizer, showing how some maneuvers can result in exceeding design lim- its and even lead to structural failure. The purpose of this Bulletin is to re-emphasize proper operational use of the rudder, highlight certification requirements and rud- der control design characteristics. Yaw control General In flight, yaw control is provided by the rudder, and directional stability is provided by the vertical stabilizer. The rudder and vertical stabilizer are sized to meet the two following objectives: Provide sufficient lateral control of the aircraft during crosswind takeoffs and landings, within the published crosswind limits (refer to FCOM Operating Limitations chapter). Provide positive aircraft control under conditions of engine failure and maximum asymmetric thrust, at any speed above Vmcg (minimum control speed - on ground). The vertical stabilizer and the rudder must be capable of generating sufficient yawing moments to maintain directional control of the aircraft. The rudder deflection, necessary to achieve these yawing moments, and the resulting sideslip angles place significant aerodynamic loads on the rudder and on the vertical stabilizer. Both are designed to sustain loads as prescribed in the JAR/FAR 25 certification requirements which define several lateral loading conditions (maneuver, gust loads and asymmetric loads due to engine failure) leading to the required level of structural strength. -

Critical Analysis of Pakistani Air Operations in 1965 Weaknesses and Strengths Arjun Subramaniam* This article tracks the evolution of the Pakistan Air Force (PAF) into a potent fighting force by analysing the broad contours of joint operations and the air war between the Indian Air Force (IAF) and PAF in 1965. Led by aggressive commanders like Asghar Khan and Nur Khan, the PAF seized the initiative in the air on the evening of 6 September 1965 with a coordinated strike from Sargodha, Mauripur and Peshawar against four major Indian airfields, Adampur, Halwara, Pathankot and Jamnagar. -

3Rupture in South Asia
3Rupture in South Asia While the 1950s had seen UNHCR preoccupied with events in Europe and the 1960s with events in Africa following decolonization, the 1970s saw a further expansion of UNHCR’s activities as refugee problems arose in the newly independent states. Although UNHCR had briefly been engaged in assisting Chinese refugees in Hong Kong in the 1950s, it was not until the 1970s that UNHCR became involved in a large-scale relief operation in Asia. In the quarter of a century after the end of the Second World War, virtually all the previously colonized countries of Asia obtained independence. In some states this occurred peacefully,but for others—including Indonesia and to a lesser extent Malaysia and the Philippines—the struggle for independence involved violence. The most dramatic upheaval, however, was on the Indian sub-continent where communal violence resulted in partition and the creation of two separate states—India and Pakistan—in 1947. An estimated 14 million people were displaced at the time, as Muslims in India fled to Pakistan and Hindus in Pakistan fled to India. Similar movements took place on a smaller scale in succeeding years. Inevitably, such a momentous process produced strains and stresses in the newly decolonized states. Many newly independent countries found it difficult to maintain democratic political systems, given the economic problems which they faced, political challenges from the left and the right, and the overarching pressures of the Cold War. In several countries in Asia, the army seized political power in a wave of coups which began a decade or so after independence. -
