S76 Handbook Cabin Floor CG loading addition data After attempting all APLH course note and RQG Centre Of Gravity calculations you should be very familiar with the process involved in all aspects of loading Reminder - There is one additional consideration, which for various reasons is not often included in any CASA exams, but may appear occasionally. This involves loading simply the 'Floor' or 'Cabin Floor' (same position) instead of specific floor compartments C4 and C5 The main reason for this type of loading being only occasionally seen in the exam is simply the real life inaccuracy in using a single arm for such a large area and lack of data in the S76 Handbook on the APS and Moment in a 'Floor'/'Cabin Floor' load configuration with tie down rings in use. To actually load the floor evenly around a single datum would be quite difficult However for the exam these questions can be treated exactly the same as any other loading position, but the relevant data is a little harder to find. Remember it appears on the top left corner of Page 50 of the S76 Handbook and you will need to do some basic conversions You will find this information there - So if you are asked to simply load the 'Floor'/'Cabin Floor' - The arm is 150.25 inches x 25.4 = 3816.4 mm (use 3816 mm - the .4 left over won't change your final answer) The maximum weight is 1300 lb / 2.205 = 589.6 kg (589 kg rounded down to not exceed limit, but you will still be within tolerance if you rounded up to 590 kg) The standard floor loading pressure limit of 366 kg/square metre still applies (75 lb/square foot = 366 kg/square metre) Once you have the arm and maximum weight converted the rest of the process is exactly the same as for any other loading station It's not harder at all. Just the extra step of finding and converting the data This RQG creates three different loading scenerio's. Standard passenger and baggage loading. C4, C5 and baggage loading. And it includes random scenerio's where loading the 'Floor'/'Cabin Floor' is required, to ensure you are familiar with finding, converting and using the 'Floor'/'Cabin Floor' data When you are creating RQG questions and there is a specific type of loading you wish to practice, you can simply hit the 'Refesh' button on your web browser and keep refreshing until you are presented with the loading scenerio you want to practice. Each loading scenerio in this RQG has about a one in three random probability of being given each refresh or new question Please Click Here to return to the login page.
