min.fuel and max. p/l
Distance - 418 NM
Mach number - 0.80
B727 basic weight - 47100kg
- Going West
- ISA, nil wind
how to find the minimum fuel and maximum payload for the flight?

Look in the Performance Manual, perhaps. Not enough information, so far. Need aircraft's maximum TOGW, accounting for runway, climb, obstacle, structural and maximum landing gross weights; sector fuel burn and alternate for starters. Also, maximum ZFW.

Weight limiting factors
- BEW - 47100kg
- Structural limitation:-
- take off – 89357kg
- landing with flap 30 – 72600kg
- landing with flap 40 – 64636kg
- Zero fuel – 63500kg
- Unlimited runway available
- No alternatives
- Fuel burn off 10kg for every nm
- Fixed reserve 3300kg
- Fuel contingency - 10% of flight fuel
- Taxi – 100kg

Still need the OAT, surface winds, airport elevation and dash number of the engines.
I'm guessing you're a simmer and so ballpark will work. You have to work the structural TO and landing limits, the takeoff runway and climb limits and the landing runway and climb limits (in case you have to go around.) For max payload you have to consider the ZFW limit. For a 727 on a short flight normally the landing structural numbers are most limiting.
Landing with flaps 40 isn't done anymore outside of Africa due to noise issues so you have
72600
-47100
- 3718 fuel remaining at touchdown
gives you 21782 available payload limited by max landing weight.
89375
-47100
- 7898 min fuel at brake release
gives you 34377 so the landing structural weight is still limiting.
However you have a weird airplane
63500
-47100
only leaves you 16400 for payload limited by MZF weight. I'd say send some money to Boeing and get a new MZFW but as I said, since you're a simmer, just send me the money and I'll get you a new MZFW.
You say you have unlimited runway - truely you've not seen a 727 with dash 9 engines on a 43 degree day. Since the runway is unlimited you'll most likely need to consider climb limits (I'm guessing since the runway is unlimited there are no obstacles.)

With that max TOGW, it would have to be a D-15 or D-17 powered -200, unless we're talking Valsan bird. I cannot imagine a D-9 powered -200 actually getting airborne on a 43C day. At Eastern, we used only D-15 727s in the western ops and they were challenged in the summer.
