Ipad battery discharging on airplane power
xftrplt replied to JohnB's topic in Avionics/Panel Discussion
I use the newest iPad (with a Ram mount on the right A-pillar, Brett's idea). Yes, it still discharges when plugged into the cigarette lighter, but so slowly (with the screen bright) that will outlast the plane's endurance, and mine. Further, there is no need to run the iPad the whole flight. Use it just when you need it; let it charge the rest of the time. Perfection: the enemy of good enough. -
Yup. But the rudder may be neutralized as the roll progresses. I think what is confusing is that in negative G flight, the upward (from the cockpit) aileron may create adverse yaw. The rudder's effect on yaw is the same: right pedal, nose right. A lot depends on whether the airfoil is symmetric or not. Non-aerobatic GA aircraft almost always have asymmetric wings, which produce lift when the relative wind is parallel to the chord. Jim, regarding Ward's question: Hint, spoilers produce proverse yaw.

Yes. Note: My above post containing only a period (.) was the result of deleting a duplicate post, not an expression of finality.

Jim, Consider: 1-G level flight-- Right rudder; nose yaws right. 0-G (parabolic flight)-- Right rudder; nose yaws right. -1-G upright flight-- Right rudder; nose yaws right. With respect the the controls, the aircraft doesn't "know" if it's right-side up or upside down.

-- A barrel roll is a positive G but not a 1-G maneuver. -- The rudder does not reverse its effect (in yaw) at negative G's.

Do you have an angle of attack indicator (poll)
xftrplt replied to 201er's topic in General Mooney Talk
José, Jim is exactly correct. The ASI is important for V1, Vr, and Vf (etc.) but otherwise (at least in theory) AoA is determining. Respectfully, Dick -

xftrplt replied to 201er's topic in General Mooney Talk
I often plan and fly 45-60 degrees in the pattern at idle, full flaps, and (sometimes) speedbrakes. Speed? What feels comfortable. AoA? Below stall, using the G-available to turn, not maintain level flight. Is this for the novice? Probably not. Safe? IMO, yes. -
When you "recoop," do you prefer chicken, pigeon, or some other type in which to recoup? Inquiring minds...

First, you're not going to "lose your motor" to shock cooling. Second, at the risk of abusing a dead equine, I suggest doing a web search on shock cooling. It's considered by many to be a myth. Here's a link to an article in AVweb: http://www.avweb.com/news/maint/182883-1.html Third, flying is all about prioritization. Even if shock cooling were true, you had bigger fish to fry.
-
Lemme see: though unsure of the terrain and obstacles, you dove with you family into a hole doing 200 mph because you didn't want to shock-cool your motor. Interesting priorities.

Strobes or mag grounding I would guess, as they're the only source of high voltage in most GA aircraft.

Sorry, mooneygirl, but I'm with Byron. He may have been an nth-generation Mooney pilot, but, as far as I know, airmanship isn't genetically transmitted. He was employed as an engineer, not a pilot. Hence a professional engineer but an amateur* pilot. And, condolences aside, his stupidity cost three innocent lives. *No pejorative intended. For example, Schliemann and Troy. (And after 50 years of flying, 40 professionally, I am now, again, an amateur.)

3 NM/1000ft = 18/1 You sure you want to plan for that?

Jim, as you probably know, the correction for GW is approximately 2Kts/100# for your difference from the book speed. Correction = (actual weight / POH weight)^2 (POH speed).
-
As I'm sure Gary knows (and positive Byron knows), aircraft weight has no significant bearing on Glide Ratio. The heavier you are, the faster you fly to hold the AOA for Max L/D. You'll go faster and descend faster, but the ratio is the same.
-
Just a thought: might it have come over your #2 radio?
-
The swivel feature is (ok, should be) unnecessary in a plane. Just ask Mr. Hoover.
-
I leave my Tannis heater plugged in for months at a time with the cord connected at the oil filler door. No problems. However, if I place an iPad on the glare shield, the whiskey compass swings 20 degrees.
-
Don't believe you can using AC. With DC certainly a probability. EE, Physics majors?
-
While I agree on the value of AoA indicators (never looked at the ASI in the overhead pattern in the F-4--just flew to the steady tone at 19.2 units, or the fast beep indicating more than 20 ), icing is one condition where it is NOT to be trusted...at least as normally used. In fact, some air transports--I believe the ATR series is one--have a lower AoA band for icing. Quite simply, with the airfoil shape distorted, a stall will occur at a lower AoA than clean. Caveat aviator.
-
I certainly may be wrong, but I see no reason not to fly these STARs with only a 4/530.
