Re: Synthetic AOA sensor

The answer seems pretty clear at this point - 170 family uses AoA measured as pressure difference over multiple pressure inputs on the probe. Which is not the synthetic value, but a directly measured one - although some numeric processing is required to obtain AoA value from those pressures. Accord...

Re: What happens if you don't stab trim an aircraft

I read that it was asked about specific aircrafts but i just wanted to denote that there are fundamental differences between for example the good old small Cessna where the autopilot can only has control via the trim (but since the trim there is not moving the entire stabilizer but rather a trim tab...

Re: Airbus studing aircraft flying in formation

I would guess that it is not meant to be manually formation flying like i image the stuff done by military but automated flying in specific locations relative to other aircrafts at closer distance then currently possible. That would most likely require some form of direct communication and therefor...

Re: Off position for landing gear handle

What would happen if you left it in UP position for the entire flight? Would it slowly depressurize anyway? No, you would just maintain pressure on the system. The “OFF” position prevents depletion of the hydraulic fluid if a leak were to develop in the landing gear system. Interesting. Don't parki...

Galley servicing limiting turnaround time

In another post tommy1808 posted this link to an airplane characteristics document for the MD-11: https://www.boeing.com/resources/boeingdotcom/commercial/airports/acaps/md11.pdf Looking over it I noticed that the critical path for the suggested usual turnaround timing involves the galley service. O...

Re: Collision question

a Beech-18 in cruise slamming head on into an L1011 on approach with 200m/s collision speed carries about as much energy as about 15 Kg of TNT. There are probably few impact points where that is survivable. Thomas While mathematically correct you have to keep in mind that depending on the geometry ...

Re: Calling all Non-pilots

Aviation as a career is screwed for the next decade. You dodged a bullet there. I am currently working at a research facility for aerospace projects. As a child it was my dream as well to become pilot but with similar thoughts as VSMUT and little money to pay for flight school I instead focused on ...

Re: Hydrogen flying wing

Here is a rough sketch of what the lay-out could look like (span is a bit on the low side). I would assume that (at least the first) implementations of hydrogen powered crafts would try to somehow "conventionally" burn the hydrogen, as large scale fuel cells are coming with a significant ...

Multiple external power switches

Hi. As an enthusiast I was reading through this forum for a while now and learned a ton of interesting facts i could not even imagine. ow its time to ask a question myself. I noticed that on the electrical panel of some airliners there are more then just one switch for the external power. E.g. on th...
