Max take off weight

Postby DieselFan » Thu Nov 17, 2005 11:37 am

Have you ever exceeded the MTOW? If so how, as the panier bags I've seen shouldn't hold much? I've read that the specs on most local trikes are roughly 450kg, so if pilot weighs 80kg, pax 80kg + ac 160kg + wing of 50kg = 370kg this leaves 80kg for sundries?

Can you fit bigger or wider bags?

Empty Weight (trike and engine only - no wing)
119 kg
262 lbs

Maximum Take Off Weight (MTOW)
450 kg
990 lbs

Typical Useful Load (Pilot, Passenger, Fuel & Gear)
281 kg
620 lbs

Design Loads
+6g -3g
+6g -3g

Taken from http://www.aerotrike.co.za/products/tri ... iperf.html

So if I take 280 - fuel - me and gf = 280-50-80-50=100kg to load?

Remember the MTOW is based on the law. It's the maximum all up weight of a microlight to remain legal. The plane is perfectly capable of exceeding that weight but it reduces your g-force rating, your climb perfomance, fuel usage etc etc. You will also be illegal based on your licence, MPL, and you will be exceeding the authority to fly.

When working out your weight remember fuel is lighter than water. (1l = .71kg). Also, take a fully clothed weight.

So your calculation would be
You - 80
GF - 50
fuel - 39Kg - (55 liter tank)
Total - 169 KG

you still have 112kg to play with.

Cool thanks I never knew fuel was .7 :!: I was getting worried about fitting a longrange tank :cry:

How do those that go camping etc tack all their stuff? As I mentioned above the panier bags look very small?

DF,

On some of our out trips we have often used the wing as packing space for reasonably light and volumetric items such as sleeping bags, mattresses and small tents. You just open the zip and pack it into the wing space. Try and ensure that the packing is more or lesss equal on the two sides otherwise the wing may be a bit out of balance making it difficult to hold level and control during take off and landing. Similarly, you also dont want to pack anything in too heavy either. It is strongly recommended that you check the balance of the wing prior to take off to avoid making extreme wing inputs.

I normally tie the load against the main pole with a bungy to prevent it from shifting position in flight. Just make sure that items are not so bulky that they change the exterior shape of the wing in any significant way otherwise the flight characteristics of the wing may change.

When you are packed, just remember to zip up the wing again afterwards.
Please also note that this may not necessarily be encouraged by the manufacturers. I normally only use the wing space when all other packing spaces are exhausted.

How much would be safe to put into the wings in terms of weight? I still can't get over what a great idea that is :o

DF- much better yet is to make use of a belly bag, slung under the trike undercart.
Its more secure, keeps the weight down low and also protects the prop on those outfield landings.

Wve been using these for many years now and can have one made 4 you down here if you like

Had a 130kg 6'6' pax for a demo the other day in the school's 582 Aquilla.
:shock:
probably the worst flight ive had in years and thats at sea level, this was with a quarter tank, and even had to pump the tires, could hardly steer the trike on the ground, and she handled like a bloody brick :x :x :evil:

I think he woulda collapsed the undecart if we had had to do a roughfield landing anywhere

Sure wished for a 912 Blade that day.

New rule 4me now: no pax over 110kg :? - females, 18 to 28, drop dead gorgous in ratio's 34:23:34 or thereabouts :P :oops: :P 8)
