How can a pilot "forget" to put down gear in C510?

[donjohnston]

It never was. I also never said anything about doing under the speed limit on limited access highways, only doing 30mph slower than other traffic. And if you are, maybe a limited access highway isn't a place for you.

Using that logic, if someone is driving the speed limit (let's just say 60MPH) and another car passes them doing 90MPH, they should get off the road at the next exit and find another route (because they are traveling 30MPH slower than other traffic).

Interesting perspective.

Here’s another C510 gear up for discussion. During a check ride. I don’t remember but I’ll circle back to the 510 procedures manual to find out definitively if you will get a gear warning if you don’t touch the flaps.

The pilot was receiving a checkride from a designated pilot examiner for his single-pilot type rating in a turbine airplane. After a series of maneuvers, emergencies, and landings, the examiner asked the pilot to complete a no-flap landing. The pilot reported that he performed the Before Landing checklist with no flaps and believed that he had put the gear down. During touchdown, the pilot felt a "thump" and thought a tire had blown; however, he saw that the landing gear handle was in the "up" position, and he noted that the landing gear warning horn did not sound because he had performed a no-flaps landing. The examiner confirmed that the landing gear handle was in the "up" position. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. A Federal Aviation Administration inspector who examined the airplane reported that the landing gear handle was in the "up" position and that the fuselage had sustained substantial damage. The landing gear was lowered and locked into place without issue after the airplane was lifted from the runway.

Nope, not even close to what I said. When someone says "I was stuck in traffic" I am sure you assume it means only 1 other car on the entire road, too.

Actually, it's exactly what you said. I quoted your message in case you didn't notice.

And who said anything about being stuck in traffic? I did search on the entire thread for the word "stuck". The only occurrence of that word was your last message.

Maybe you're the one who should consider staying off limited access highways?

I did not say a singular car on the road, you did.
You're probably the only person that refers to a singular car as "traffic."
I place you somewhere around 90 < 180 and I'm not talking IQ.

Okay. A person is driving on I-285 in Atlanta (That's the interstate which goes around Atlanta). They're traveling at the posted speed limit of 55. Numerous cars are passing that person doing 85 (which I assure you is normal). According to your beliefs, that person shouldn't be driving on that road. They should confine their driving to surface streets since they are driving too slow.

Or are you going to change what you said again?

A Federal Aviation Administration inspector who examined the airplane reported that the landing gear handle was in the "up" position and that the fuselage had sustained substantial damage. The landing gear was lowered and locked into place without issue after the airplane was lifted from the runway.

I posted it back on page 1:
The warning/caution advisory system provides a landing gear aural warning if one or more gear are not locked down and either of the following situations occurs:
1) One or both throttles are retarded below approximately 85% N2 and airspeed is below 130 KIAS. Pressing the HORN SILENCE-PUSH button on the gear control panel (see Figure 14-7) silences this warning.
2) Flaps are extended beyond the TAKE OFF AND APPROACH setting. In this situation, the aural warning cannot be silenced with the HORN SILENCE-PUSH button.

So unless you are landing at >130KIAS (almost 2x normal landing speed) or with almost full power (good luck forcing it down to the runway), you will get an aural gear horn warning even with flaps up. Of course this assumes the system is functioning and the breaker hasn’t been pulled. But the most likely candidate is that the pilot reflexively pushed the silence button when he heard the horn without realizing he was doing it. It’s done a lot in training and becomes part of muscle memory if you aren’t careful.
