Use of Rudder on Boeing Aircraft
12ADOBL02 December 2011 Use of rudder on Boeing aircraft According to Boeing the Primary uses for rudder input are in crosswind operations, directional control on takeoff or roll out and in the event of engine failure. This Briefing Leaflet was produced in co-operation with Boeing and supersedes the IFALPA document 03SAB001 and applies to all models of the following Boeing aircraft: 707, 717, 727, 737, 747, 757, 767, 777, 787, DC-8, DC-9, DC-10, MD-10, md-11, MD-80, MD-90 Sideslip Angle Fig 1: Rudder induced sideslip Background As part of the investigation of the American Airlines Flt 587 crash on Heading Long Island, USA the United States National Transportation Safety Board (NTSB) issued a safety recommendation letter which called Flight path for pilots to be made aware that the use of “sequential full opposite rudder inputs can potentially lead to structural loads that exceed those addressed by the requirements of certification”. Aircraft are designed and tested based on certain assumptions of how pilots will use the rudder. These assumptions drive the FAA/EASA, and other certifica- tion bodies, requirements. Consequently, this type of structural failure is rare (with only one event over more than 45 years). However, this information about the characteristics of Boeing aircraft performance in usual circumstances may prove useful. Rudder manoeuvring considerations At the outset it is a good idea to review and consider the rudder and it’s aerodynamic effects. Jet transport aircraft, especially those with wing mounted engines, have large and powerful rudders these are neces- sary to provide sufficient directional control of asymmetric thrust after an engine failure on take-off and provide suitable crosswind capability for both take-off and landing. -

Touring Rudder Sit-On Top Kit Kit to Fit Rudder Enabled Sit-On Tops with a 10Mm Rudder Fixing Point
touring rudder sit-on top kit Kit to fit rudder enabled sit-on tops with a 10mm rudder fixing point. Note: It is easier to fit the Touring Rudder System if you have a screw hatch fitted to the rear stowage area of the kayak. If your kayak does not have this screw hatch and you wish to fit one, please contact a Perception dealer for advice. These instructions explain how to fit the rudder kit to a kayak with or without a rear screw hatch in place. Please make sure you follow the correct steps for your version of sit-on top kayak. This kit should contain the following: 1x rudder assembly with up-haul rope & split ring 4x deck fittings 4x length of rudder hose 5x self tapping screws 2x Dyneema control line - with cord end assembly 2x oval toggle 1x pair of Tip-Toes control footrests with foam washers 1x length of 4mm shock cord 6x footrest screws, washers and nuts - pre-fitted 1x rudder park - inc. hook, shock cord & fixing block You will also require some tools to fit this kit: Drill with 3mm, 5mm and 6mm drill bits Marker pen Short phillips screwdriver Wire cutters Small adjustable spanner or pair of pliers Lighter Tape measure Small amount of sticky tape Please read these instructions carefully before fitting! Step 1 - Control line entry points The rudder will need to have two control lines attached, each one running through hose sections inside the kayak from the rudder to the Tip-Toes footrests. This kit has four hose sections (two pairs) as two sections are needed per control line. -

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. -
