So it's single channel but it looks like ap1 and ap2 are engaged at the same time? Whys that?

On this approach, both APs had been engaged in preparation for a dual channel approach. Initially, the AFDS annunciates (and the approach is) single channel. At 1500' RA, pitch and roll confidence monitor tests occur - basically ensuring maneuvering and fault monitoring capability. If the tests are passed, the system then annunciates CMD, indicating that the approach has now become dual channel.

Hence, at the point this shot was taken, it was still a single channel approach, but became dual channel later.

Any of y'all: Let's play a game. It requires:

- a 172
- a suitcase of 100 dollar bills.

It works like this: I use the first few bills to rent the 172, and we go flying. Then, I command you to set an airspeed of my choosing (could be anywhere from 1G stall to Vne). I give you a hundo as soon as you set it, and then give you another one for every 10 seconds you maintain it to an accuracy of a needle-width. This may last from a few seconds to a few minutes, at my whim. Then I think of a new airspeed and we rinse and repeat until the suitcase is empty.

The only catch is that I tie one of your hands behind your back. Which hand would you rather have available?

Right hand (if I'm in the left seat). Trim and power. More accurate speed control and my flight path won't be +-1000's of feet while doing so.

Re: the game, in the T-6 I want my left hand because I can more easily switch between throttle and stick that way, the PCL's on the left side :v:

But yeah, given the "only touch one for the whole flight" I'd want to have control of the yoke vice power. Either way you can screw me but I think I can get to a desired airspeed way faster with pitch than I will with power.

I should've been a little more exact in my wording: if I'm low AND slow, and my not-fully-thinking response is to (only) pitch for the airspeed I need, all of a sudden I'm low and going even lower and I'm probably gonna hit something (but hey, I'll be hitting it at approach speed!). In that situation you should maintain nose attitude and add a LOT of power in order to get your airspeed and your sink rate/altitude under control simultaneously.

I always mentally view it as an energy-management game. If I'm slow I need more kinetic energy, which I can get by trading excess potential energy (trade altitude with pitch if I'm high) or by just adding more energy to the system (by increasing power if I'm on-altitude). If I'm fast, I can either trade that excess energy for altitude if I'm low (which I shouldn't be, but maybe I'm out of trim and got low because my scan was bad) or I need to wipe some power off to dissipate energy. Similarly for high or low.

Like others have said, either way of thinking about it will work, and pitch/power/speed/sink rate are all interrelated.

I agree with the first 2 paragraphs, except you left out, in the first sentence I bolded, that you'd have to also reduce AOA. Otherwise, that added energy will translate into a less-steep descent (or, in a more extreme case, climb) at the original airspeed. For the second bolded sentence, likewise increase AOA, or the dissiapted energy will steepen the descent. Remember that AOA determines airspeed for steady flight.

I also agree that pitch/power/speed/sink rate are all related, but just leaving it as such doesn't shed any understanding on the nature of that relationship. And either way of thinking about it will work in normal situations, but any time the chips are down and someone is liable to forget something, I'm a firm believer that the Navy method will leave the pilot with a more survivable situation. If the Asiana 214 pilot had a gut-level need for more power at the first indication of a low position, rather than naively aiming the nose where he wanted to go, that accident wouldn't have happened.

You're getting around my catchy, cute, and hilarious way of saying that you're only allowed to touch the yoke (or yoke-related item like trim) OR throttle, for the entire flight.

Also I never said anything about flight path, just airspeed. I'm isolating the factors here so we can really see what controls what.

No screwing involved, you'd have fairly and squarely won your money by meeting the condition.

Also I always get wigged out and confused any time someone calls the T-6 II the T-6. Takes me a second to figure out what plane they're talking about.

Question from a would-be pilot that's been bugging me. I know that there's air speed and ground speed, and ground speed is air speed plus any air mass movement; but does rotation of the planet factor in any, or are we still in the reference frame of the planet and rotating with it?

Everything on the ground, and the atmosphere all rotate with the planet. Yes, you're moving faster as an absolute, but to any reference that matters to an air breathing airplane, planetary rotation has no effect.

Think of earth as an enormous treadmill.

Not in any meaningful amount, the airmass is rotating with the planet.

It be pretty wild if it were though, you could hover in a helicopter to travel west and eastbound travel for anything but the concord would be nigh impossible.

Dear diary, I got another erection today at work. SO embarrassing, but kinda hot. The CO asked me to fix up his dress uniform. I had stayed late at work to move his badges 1/8" to the left and pointed it out this morning. 1SG spanked me while the CO watched, once they caught it. Tomorrow I get to start all over again...


A little mid afternoon pit stop. Got to do my first missed approach in actual weather followed by a PAR to mins in a fog bank. Talk about something that will make your hands shake a little. Don't remember what the mins were on it but the hairs on the back of my neck start standing up when you hit below 200 feet on the radio altitude. Thank god for approach lighting.

Then put it in a hover right on the numbers :cool:

Oops! You're right. He should have said "relative to the inertial (or, non-rotating) frame of reference fixed to the center of the Earth."

Going East, that's gonna be faster than the groundspeed, and going West, it's gonna be slower.

Interestingly, the Space Shuttle, due to having to operate both as an aircraft near the surface, where Earth-based velocity information was relevant, and in space, where Inertial ("absolute," as it were) velocity information was relevant, had 2 bearing pointers on the DG, one for each... marked E and I respectively. On ascent, they'd fly the E pointer until a high enough altitude that most of the atmosphere was gone, then it would disappear and then they'd fly the I pointer.

Successfully avoided having a deal last night.









Lost a valve on cylinder #1 after takeoff.

Didn't declare, started running rough around 400-500agl after turning crosswind, RPMs instantly dropped to 2200 or so and continued dropping, notified tower of engine problems and requested immediate landing, they told us to pick a runway and moved a Learjet on final to the far parallel.

We didn't know was going on, but got a clue it was something bad when we started smelling oil smoking off of the exhaust when we were on final, and had no idea it was as bad as it was until we got out and saw the landing gear coated with oil and a growing puddle underneath.

Trying to work through airlineapps. Question on the driving history.. they have NO cutoff. Also, one charge I had was reduced - do I put the original or the court reduced? There was another ticket that the court dismissed. I know this is a.. risky nebulous area as far as nondisclosure of anything goes being very likely to disqualify you. But a dismissed ticket means legally you did not commit the infraction... so it shouldn't go on there, right? My record has been very clean for 5+ years now, it was all youthful indiscretion. Also, I don't even know where to start with putting stuff on there. Do I go to the DMV and get a driving record? Is there a way to order a background check on myself online that would include it?


Edit: California driving history shows nothing. Thought I got a ticket there at one point. Looks like I'll have to go in person to get my Washington one. Those are the two states I've driven in, with the addition of Arizona but I never got pulled over in Arizona (I'm not latino, so the cops didn't care about me.)

Edit2: Got the Washington one. It only shows 1/20/07 "Failure to yield right of way." and nothing else. I got two speeding tickets that don't show up at all, one I did traffic school for and one that was just straight up dismissed. That was like 2006-2007ish. Not sure what to throw on airlineapps. :( I don't mind putting them on there with a status of 'dismissed' but I don't even know the dates, it was at least 7 years ago and apparently the state agencies haven't kept that record...

Don't mention anything that doesn't show on public records. Keep a copy of the clean records. Something from 2007 will not be a factor for regionals right now. In fact, they would probably hire someone with a DWI in the past five years (then they know that person is not going to the majors!)
