CAA Doc 743 Civil Air Displays a Guide for Pilots
Safety Regulation Group Civil Air Displays a guide for pilots contents introduction Introduction Air displays are now one of the most popular The law spectator events in the United Kingdom. On average there are over 250 civil flying displays Guidance for display each year attracting in excess of two million pilots spectators. It is of the utmost importance in the interests of public and personal safety, that those Managing the risk who participate in such displays operate to the highest standards. These notes are intended to Planning your provide advice to display pilots to help them display avoid the pitfalls which have been experienced in the past. Practising for your display The air show Display day Post display © Andrew Critchell 1 the law The rules governing the conduct of civil air displays in the United Kingdom are given in the current Air Navigation Order, The Rules of the Air Regulations and comprehensively explained in CAP 403 – “Flying Displays and Special Events: A Guide to Safety and Administrative Arrangements”. guidance for display pilots Display flying, especially aerobatics, is a specialised form of flying that frequently involves flying the aircraft close to the edges of the permitted flight envelope. Regrettably, most years, a small number of pilots are killed whilst displaying. Many of these pilots were highly experienced and extremely competent in their particular aircraft and display. What can be done to minimise the risk? managing the risk personnel fitness There are a large number of factors which affect the outcome of a particular flight. Many of them are encountered well before the pilot gets anywhere near the aircraft. -

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.

Maneuver Descriptions
2017-2018 Senior Pattern Association Section III Maneuver Descriptions NOTE: MANEUVER DESCRIPTIONS THAT FOLLOW ARE TAKEN VERBATIM FROM THE APPROPRIATE AMA RULE BOOKS FROM WHICH THE MANEUVERS WERE TAKEN. THE ONE EXCEPTION IS FOR THE SQUARE HORIZONTAL EIGHT, FOR WHICH EVERY APPEARANCE IN THE AMA RULE BOOK ENDED AS AN INCOMPLETE DESCRIPTION. THE SPA BOARD HAS CREATED WHAT WE THINK WOULD BE THE APPROPRIATE ENDING, WHICH IS SHOWN ON PAGE 34 IN ITALICS. Anatomy of an SPA Maneuver by Phil Spelt, SPA 177, AMA 1294 SPA pilots are flying what is called “Precision Aerobatics,” in the official AMA publications” -- the old-time way (pre turnaround). The emphasis in that name is on the word “Precision.” That means pilots are supposed to display precise control of their aircraft in front of the judges. This precision should, ideally, be shown from the moment the plane is placed on the runway until it stops at the end of the landing rollout. Technically, the judges are only supposed to “judge” during the actual maneuvers, but they will notice either wild or tame turnarounds – whether deliberately or accidentally. An SPA maneuver consists of five sections, which can be viewed as an onion sliced through the middle vertically – so there are 2 pairs of layers, or parts, surrounding the actual maneuver in the center, as illustrated. The outer pair (sections 1 and 5) comprises the “free flight” area, which is used to turn the aircraft around and get it lined up to enter the next maneuver. Most pilots use a Split-S maneuver for the turnaround, thus maintaining the track of the plane at the distance from the runway at which the maneuvers are performed. -

September Meeting Notes
October 2009 20 Issue 10 September Meeting Notes Hey everybody. Inside this issue: George started off the meeting with a report on the CP event. There were not Meeting Minutes many spectators (the weather was bad that day), but there were 30 registered pilots, so that was good. The demos were excellent and so was the BBQ. The bottom line Lunch Hour was a $5862 donation for United Cerebral Palsy of Colorado. This included some cor- Pitts Special porate sponsors (Jeppesen $2k, Aeroworks $1.5k, the catering company $800, Dex, etc.) There were 25 MAS members who volunteered at the event. Thanks to all of you. Without you, the event would have a been a failure. In addition to your time, the club donated the fees for the extra Porta-potty and also all the work for getting the field looking great. On September 19th, MAS was hosted by Aeroworks at their Aurora headquar- ters. Aeroworks gave members a tour of the facility and showed them what planes are being developed. Our esteemed leader Hank won himself an electric plane in a draw- ing. Just to let all Adams County voters know, one of our members, Mark Nicastle, will be running for Sheriff in the 2010 election. Not to sway any votes, but Mark's a good guy and has done a lot for the club over the years. The October meeting is when we elect officers for 2010. We need volun- teers! (show up and vote/volunteer now is your chance to change things you don't like) Upcoming meetings and events Hank and Ron will not be staying on as President and VP, so we need some Meeting Oct 22 new people for the jobs. -
