Cover photo: Helicopter short-haul rescue of an Austrian climber on the 3’000 foot El Capitan Nose Route at Yosemite National Park (CA). During the third day of his ascent on September 26, 2011, the climber, who was 2,000 feet above the floor of Yosemite Valley, clipped an etrier, a short ladder of sewn webbing, to a metal nut wedged in a rock crack. As he stood with his weight on the etrier, the nut pulled loose and he sustained a fall, being caught by his belay safety line. During the fall, the etrier became wrapped around his thumb, amputating the digit. Yosemite Search and Rescue (YOSAR) personnel Dave Pope and Jeff Webb were inserted to the scene, in order to extract the injured climber beneath Helicopter 551 (Bell 205A-1) helicopter being piloted by Richard Shatto with assistance from helicopter crew chief Eric Small.

For several decades, United Nations peacekeeping has evolved significantly in its complexity. The spectrum of multi-dimensional UN peacekeeping operations includes challenging tasks such as restoring state authority, protecting civilians and disarming, demobilizing and reintegrating ex-combatants. In today’s context, peacekeeping missions are deploying into environments where they can expect to confront asymmetric threats and contend with armed groups over large swaths of territory.

We accept no responsibility for the use or application of this information. We suggest that readers contact the specific government and military programme offices if seeking to confirm the reliability of any data. 1 MARKET OVERVIEW Broadly speaking, the global helicopter market is currently facing a two- pronged assault. The military helicopter segment has been impacted significantly by continued defense budgetary pressures across most traditional markets, and a recent slide in global crude oil prices has impacted the demand for new civil helicopters as well as the level of activity for existing fleets engaged in the offshore oil & gas exploration sector. This situation has impacted industry OEMs significantly, many of which had been working towards strengthening the civil helicopter segment to partially offset the impact of budgetary cuts on the military segment. However, the medium- to long-term view of the market is promising given the presence of strong fundamentals and persistent, sustainable growth drivers. The market for military helicopters in particular is set to cross a technological threshold in the form of next-generation compound helicopters and tilt rotorcraft.

  • Medium Support Helicopter Aircrew Training Facility (MSHATF)
    Medium Support Helicopter Aircrew Training Facility (MSHATF) Introduction to CAE’s MSHATF The Medium Support Helicopter Aircrew Training Facility (MSHATF) was developed by CAE in partnership with the UK Ministry of Defence. Responsible for the design, construction and financing of the facility that opened in 1999, CAE operates the MSHATF under a 40-year private finance initiative (PFI) contract. CAE’s MSHATF is delivering the total spectrum of synthetic aircrew training demanded by the UK Joint Helicopter Command Support Helicopter Force. The turnkey training program includes academic classroom training and simulator training delivered by experienced instructors. The MSHATF is equipped with six full-mission simulators configured for CH-47 Chinook, AW101 Merlin and Puma helicopters. Under the terms of its PFI contract, CAE also has the ability to provide turnkey training to third-party users. This enables approved military and civil operators across the globe to take advantage of the advanced simulation, training and mission rehearsal capability at the MSHATF on a highly cost-effective basis. Other NATO nations and wider alliances also regard the MSHATF as part of their normal training regime. For example, Royal Netherlands Air Force Chinook crews routinely train alongside their Royal Air Force (RAF) counterparts before operational deployments. In addition, Royal Navy crews operating the UK Merlin and other operators of the AW101 helicopter such as the Royal Canadian Air Force, Royal Danish Air Force, and Portuguese Air Force use the advanced Merlin simulators for a range of training applications, including battlefield and search and rescue (SAR) roles. The MSHATF also offers Puma helicopter training where the customer base includes the RAF and several Middle Eastern customers.
