Ff 89/6 Copy
$3 vol libre • free flight 6/89 Dec - Jan POTPOURRI SAC was informed by Sport Canada on the 10th of July that we are not eligible for funding for 1989-90 and until further notice. Thus we are now totally on our own. The average yearly grant from 1979 to 1988 in 1989 dollars was $14,000, or $16 per person. Perhaps it’s a good thing as planning in an atmosphere of doubt is not conducive to good health and efficient use of funds. The cutback was not unexpected and steps were taken early on to ease the effects of this loss of revenue. Imaginative planning in our small store and a good response from our members through the use of the “Soaring Stuff” inserts resulted in in- creased sales. We will also receive higher than projected invest- ment income essentially due to careful cash management and short-term interest rates, which have remained higher for longer than generally expected. In addition, a small gain in projected receipts from an unexpected increase in membership – now at 1423 – which is the first time since 1982 that we have passed 1400. Total expenditures should come in well below budget projection, primarily as a result of scaling back meetings and travel expenditures. On balance it seems fair to say that a combination of some tight fistedness on the expenditure side and a bit of luck on the revenue side will leave SAC in a financially stronger position than was expected at the beginning of the season, despite the cutting off of govern- ment funding. -

Circular Administration
Advisory US.Depanment 01 Tronsporlolion Federal Aviation Circular Administration Subject: A HAZARD IN AEROBATICS: Date: 2/28/84 At No: 91-61 EFFECTS OF G-FORCES ON PILOTS Initiated by: AFO- 800 ; Change: AAM-500; AAC-100 1. PURPOSE. Because aerobatic flying subjects pilots to gravitational effects (G's) that can impair their ability to safely operate the aircraft, pilots who engage in aerobatics, or those who would take up such activity, should understand G's and some of their physiological effects. This circular provides background information on G's, their effect on the human body, and their role in safe flying. Suggestions are offered for avoiding problems caused by accelerations encountered in aerobatic maneuvers. 2. BACKGROUND. Aerobatic flying demands the best of both aircraft and pilot. The aircraft must be highly maneuverable, yet tolerant of G-loads. The pilot must possess skill and physiological stamina. He or she must be daring, yet mindful of the aircraft's limitations as well as his or her own. Federal Aviation Administration (FAA) Advisory Circular No. 91-48, "Acrobatics-Precision Flying with a Purpose," dated June 29, 1977, discusses some of the airworthiness and operational aspects of aerobatics, but does not consider biomedical factors. The most important of these biomedical factors is the pilot's response to accelerations (or G-loading). The major physiological effects of G-loaaing vary from reduced vision to loss of consciousness. The pilot who understands these effects will be better able to cope with them so that he or she can continue the sport of aerobatic flying. J. -

THE CREW BOARDED THE ACFT AND TAXIED OUT FOR DEP. WITNESSES, INCLUDING TWO PLTS WITH AEROBATIC EXP, WATCHED THE ACFT DEP, MAKE A LEFT TRAFFIC PATTERN AND DO A LOW FLY-BY DOWN THE RWY. AT THE DEP END OF THE RWY, THE ACFT PITCHED UP INTO A STEEP CLIMB. AT 600 FT AGL, THE ACFT ENTERED A LEFT AILERON ROLL, WHICH THE WITNESSES SAID WAS 'SMOOTH, COORDINATED AND WITH THE NOSE ON THE POINT.' AT THE INVERTED POINT OF THE ROLL, THE ROLL CHANGED FROM AN AILERON TO A BARREL ROLL. ONE PILOT WITNESS SAID THAT IT APPEARED THE 'CREW LOST IT AT THE TOP' AND THAT THE CREW 'HELD THE BACK PRESSURE TOO LONG AT THE TOP.' AT THE 270 DEG POINT OF THE ROLL, THE ACFT WAS SEEN TO 'FALL OUT' OR 'DISH OUT' OF THE ROLL; IT RECOVERED TO WINGS LEVEL FLT AT ABOUT 100 FT AGL IN A VERY NOSE HIGH ATTITUDE SETTLING INTO THE GROUND WITH A HIGH VERTICAL DESCENT RATE. NO PREIMPACT ENG OR CONTROL SYSTEM MALFUNCTIONS WERE FOUND. Probable Cause and Findings The National Transportation Safety Board determines the probable cause(s) of this accident to be: IN FLIGHT LOSS OF CONTROL BY THE PILOT FLYING WHILE PERFORMING AN INTENTIONAL LOW LEVEL AEROBATIC MANEUVER. -
DCS: Su-27 Flanker Flight Manual
[SU-27] DCS DCS: Su-27 Flanker Eagle Dynamics i Flight Manual DCS [SU-27] DCS: Su-27 for DCS World The Su-27, NATO codename Flanker, is one of the pillars of modern-day Russian combat aviation. Built to counter the American F-15 Eagle, the Flanker is a twin-engine, supersonic, highly manoeuvrable air superiority fighter. The Flanker is equally capable of engaging targets well beyond visual range as it is in a dogfight given its amazing slow speed and high angle attack manoeuvrability. Using its radar and stealthy infrared search and track system, the Flanker can employ a wide array of radar and infrared guided missiles. The Flanker also includes a helmet-mounted sight that allows you to simply look at a target to lock it up! In addition to its powerful air-to-air capabilities, the Flanker can also be armed with bombs and unguided rockets to fulfil a secondary ground attack role. Su-27 for DCS World focuses on ease of use without complicated cockpit interaction, significantly reducing the learning curve. As such, Su-27 for DCS World features keyboard and joystick cockpit commands with a focus on the most mission critical of cockpit systems.

Selig-2014-Jofac-Fli
JOURNAL OF AIRCRAFT Vol. 51, No. 6, November–December 2014 Real-Time Flight Simulation of Highly Maneuverable Unmanned Aerial Vehicles Michael S. Selig∗ University of Illinois at Urbana–Champaign, Urbana, Illinois 61801 DOI: 10.2514/1.C032370 This paper focuses on full six degree-of-freedom aerodynamic modeling of small unmanned aerial vehicles at high angles of attack and high sideslip in maneuvers performed using large control surfaces at large deflections for aircraft with high thrust-to-weight ratios. Configurations, such as this, include many of the currently available propeller- driven radio-controlled model airplanes that have control surfaces as large as 50% chord, deflections as high as 50 deg, and thrust-to-weight ratios near 2∶1. Airplanes with these capabilities are extremely maneuverable and aerobatic, and modeling their aerodynamic behavior requires new thinking because using traditional stability- derivative methods is not practical with highly nonlinear aerodynamic behavior and coupling in the presence of high prop-wash effects. The method described outlines a component-based approach capable of modeling these extremely maneuverable small unmanned aerial vehicles in a full six degree-of-freedom real-time environment over the full 180 deg range in angle of attack and sideslip. Piloted flight-simulation results for four radio-controlled/unmanned- aerial-vehicle configurations having wingspans in the range from 826 mm (32.5 in.) to 2540 mm (100 in.) are presented to highlight the results of the high-angle aerodynamic modeling approach. Maneuvers simulated include tailslides, knife-edge flight, high-angle upright and inverted flight, rolling maneuvers at high angle, and an inverted spin of a biplane. -
Unusual Attitudes and the Aerodynamics of Maneuvering Flight Author’S Note to Flightlab Students
Unusual Attitudes and the Aerodynamics of Maneuvering Flight Author’s Note to Flightlab Students The collection of documents assembled here, under the general title “Unusual Attitudes and the Aerodynamics of Maneuvering Flight,” covers a lot of ground. That’s because unusual-attitude training is the perfect occasion for aerodynamics training, and in turn depends on aerodynamics training for success. I don’t expect a pilot new to the subject to absorb everything here in one gulp. That’s not necessary; in fact, it would be beyond the call of duty for most—aspiring test pilots aside. But do give the contents a quick initial pass, if only to get the measure of what’s available and how it’s organized. Your flights will be more productive if you know where to go in the texts for additional background. Before we fly together, I suggest that you read the section called “Axes and Derivatives.” This will introduce you to the concept of the velocity vector and to the basic aircraft response modes. If you pick up a head of steam, go on to read “Two-Dimensional Aerodynamics.” This is mostly about how pressure patterns form over the surface of a wing during the generation of lift, and begins to suggest how changes in those patterns, visible to us through our wing tufts, affect control. If you catch any typos, or statements that you think are either unclear or simply preposterous, please let me know. Thanks.

Safety Airspace Regulatory
Safety Safe Winch Launching Quiz. As many pilots will be aware, there are a number of safe winch launching education resources at https://www.gliding.co.uk/safewinchlaunching. These include the safe winch launching quiz that allows pilots of all experience to test their own knowledge on this important topic. Some clubs now include the quiz as a required element of winch launch training, as listed on the BGA pilot training progress card at https://members.gliding.co.uk/library/pilot-training/bga-training-card/. Why not test your knowledge today? Airspace Leeds Bradford ACP. Leeds Bradford Airport is consulting on an airspace change proposal. Details are available at http://www.leedsbradfordairport.co.uk/about-the-airport/airspace- change-proposal-consultation. The consultation closes on Friday 6th October 2017. A regional gliding club/BGA response is being developed and we expect to be able to offer guidance on the key issues by the end of August. Once that guidance is available, we will be encouraging individual club responses and individual pilot responses. If you believe that you will be impacted by the proposed changes, please be prepared to respond. RA(T) Airspace File. George Knight and Alan Sparrow have modified the ASSelect program so that it now includes RA(T)s. RA(T)s are currently designated in ASSelect as LoAs but this will be changed in due course. Please remember that this information does not replace daily checking of NOTAM information. ALWAYS check NOTAMs before flight. ASSelect file can be downloaded from http://soaringweb.org/Airspace/UK/ASSelect.html.
