S76 MTOW Payload Scenarios Notes
This RQG is simply additional revision of the steps required to determine the MTOW you can plan for VFR and IFR scenarios as described on Pages 37 to 41 of the course notes
You may also be asked to calculate the maximum additional cargo you can load after considering the performance limitations
The questions give the initial graph weight restrictions and the FBO (Fuel Burn Off) allowances, so all you are doing is applying the steps to work out the most limiting stage of the flight and bring that back to a MTOW
Because every graph limit and the FBO allowances are given, the tolerance in the final answer you submit is absolute zero. There is only one correct answer with nowhere else to go
Some IFR examples refer to an enroute LSALT limitation without mentioning the initial or first LSALT. That simply means the initial LSALT wasn't limiting. Don't think too hard. Just use the data you have been given
So this RQG is practice at not only the process for finding the MTOW, but it is also a good exercise in accurate transfer of numbers from the screen to your calculator and it makes sure you read the data carefully
In particular make sure you check if the FBO is given from takeoff vs startup so you don't make a 40 lb mistake. And is the final answer required in lb or kg?
After doing a few examples you should be able to look over the initial data given and guess the outcome before you even pick up a calculator. Being able to predict the outcome in advance can save time on exam day
If an answer in kg is required the conversion factor is 1 kg = 2.205 lb and the instruction is to round to the nearest kg.. half way or more between kilograms answers round up and less than half way round down as per the exam info book. Because the initial weight limits would have come from graphs with a tolerance applied, we aren't busting any fixed limit by rounding up. It's just an instruction for you to follow as part of the process here and if you round the wrong way you will be marked wrong at the end
This is not a difficult RQG. It is good practice in gaining confidence transferring numbers and following the steps to ultimately determine payload capacity
