aj_richo Posted January 28, 2014 Posted January 28, 2014 Hi Guys, I'm trying to find a reference for standard pilot weight for W&B calculations. I thought I read somewhere that it had been upped from 75KG to something like 80KG, but haven't been able to find anything definitive. Any pointers out there? Thanks in advance Richo
Bob Llewellyn Posted January 29, 2014 Posted January 29, 2014 Hi Guys,I'm trying to find a reference for standard pilot weight for W&B calculations. I thought I read somewhere that it had been upped from 75KG to something like 80KG, but haven't been able to find anything definitive. Any pointers out there? Thanks in advance Richo In the beginning, it was 170lb (77kg); then it arose, and (pausing briefly at 80kg in a few draft Design Standards) became 86kg. CAP-482 (BCAR-S), JAR VLA (is it EAR-VLA now? No, CS-VLA, that's right...), ASTM 2245 (LSA, US-style) all use 86kg. I suspect something - Transport Category seat design? - uses 90kg, but if you're under 5,400kg MTOW, 86kg is considered the upper limit. 50kg is about the lower limit. 1
Bob Llewellyn Posted January 30, 2014 Posted January 30, 2014 No worries, thanks Bob No worries - a bit of extra history: CAO 95:55 uses 80 kg for the "minimum useful load" calculation for foreign certified ultralights...
coljones Posted January 30, 2014 Posted January 30, 2014 But at the end of the day it is the actual load that is important. The PIC must take into account actual loads when going flying. If these actual loads exceed W+B limits or takeoff and landing limits then it should be a no-go. Given that some of us are heading towards 100Kg it would be nice to have a plane that was certified to carry us, our handbag and enough fuel to enjoy ourselves (with a 45 min reserve) 1
aj_richo Posted January 30, 2014 Author Posted January 30, 2014 Happily I'm still 87kg in my Sunday best. I was more concerned about the passenger weight, but I guess I could do a selection of passengers say from 50kg to 100 kg so I have a ready reference. 1 1
Ryanm Posted January 31, 2014 Posted January 31, 2014 That's the best way to go (calculate at various weights to see what fuel you can/cannot carry). But you should always do a complete W&B for each sector and as others have said, you must use actual weights with smaller aircraft.
Doug Evans Posted January 31, 2014 Posted January 31, 2014 Bugger i am 107 kg ............ Is that bad ? Aircraft 205 kg Fuel 66 plus aux 35 lt total 100 lt 107 me 205 plane 100 fuel 66 wife 478 kg total. Mtow was 480 kg but RAA drop me back to 450kg last year now I have 400 kg this year now I have to be careful . Plane was 480 kg mtow But has changed ????

The fuel is (66+35)=101L* The density of petrol is around 0.72Kg/Litre (for 100LL) therefore your fuel load will be around 72.72Kg - a saving of 27.28Kg, enough for a MTOW of 451KG - have a loo break before flying
