Re: How much hydraulic pressure does the APU provide vs the engines?

APU doesn't provide any hydraulic pressure - it's just a pneumatic air source and an electric power source. even though the engine driven pumps supply a higher flow than the electric pumps, the system pressure is still 3000psi whether it comes from the engine driven pumps or the electric motor drive...

That’s kind of normal if you’re trying to nonrev on AA between DFW and ORD precovid.

DFW to OKC/DSM/STL/MCI/ICT/TUL/XNA/COU/IAH/AUS/SAT to ORD or vice versa.

Much easier to do than DFW - ORD direct.

Though the Texas outstations of IAH/AUS/SAT could be harder than just going to ORD directly.

At least in the US, calculating runway landing performance is required before landing. It is computed with no thrust reverser usage. And then 10% is added to arrive and required landing distance.

So any thrust reverser usage will result in a landing distance less than what is calculated.
