Is it possible to land an airliner with no hydralics?

This is about as close as you could get with no hydraulics. They steered using differential thrust, which at least allowed them to crash at an airport.

The B-747, DC-10/MD-11 and L-1011 will crash -

Hydraulics required for flight controls for these airplanes -

See crash of JAL123 and UAL DC-10 in Sioux City .

Smaller airplanes - 727-737-DC9 etc. can be flown without hydraulics.

Flight controls can be (cable) operated "with muscles" (manual reversion).

Getting the landing gear down is another issue.

Most if not all airplanes have alternate means of gear extension.

Requires NO hydraulics = mechanical lock, by gravity or electrical extension.

Depends on the aircraft. A small airplane, it's possible. A large airliner… no. However, as others have pointed out, there are numerous redundant systems; and a total hydraulics failure is highly unlikely.

Yes. The landing gear can be extended using the headwind and a backup electric pump or by an accumulator.. The flaps can be dropped free-fall and the elevators have a mechanical back-up.

Airlines have 4 to 6 independent hydraulic circuits so a total hydraulic failure is unlikely.

Only a Douglas product.

read about a DHL plane flying from Iraq that got hit with MANPADS.

Don't think so.

There are some planes that used electronic screw jacks, but they have been known to fail more than hydraulics. And it is easy to have dual redundancy with hydraulics.

Probably, youd just have to use something other than hydraulics

Yes it is.

Sure...its called a crash.
