Flight to Shuttle Landing Facility in a Piper Malibu PA46 - 310P
Просмотров 2,2 тыс.4 года назад
This video presents a VFR flight from Space Coast Regional in Titusville to a full stop landing at the Shuttle Landing Facility in a PA46 Piper Malibu.
Thank you for this excellent educational post. Can you share your height with us?
Hey, Have enjoyed your content. Do you still fly the Malibu? Am exploring purchasing one. Would very much like to get thoughts from you, both (+)s & (-)s. Possible we can connect over emails/texts?
I don't have the Malibu, these days I am flying a Meridian. I do have a book that might be helpful: Understanding Maintaining and Flying the Piston PA46, available from Amazon. It covers all the piston PA46 models (Matrix, Malibu, Mirage and M350).
Great video. Thanks! How long did this flight take you?
A bit less than 6.5 hrs.
Excellent video. Thank you so much.
You are welcome!
so basically, if your speed is fast, in order to stay in the same distance, you dont have to bank that much, it also means you wont lose that much vertical lift, that why your altitude is high when at a higher ground speed????
It's eye watering the amount of money aviation requires, especially when you start getting into turboprops and, even more so, turbofans. I will never understand how anyone can afford to operate these things.
Great vid thanks for sharing,
thank you
1800$ per blade, did I understand it well? how many of those does each turbine have, 20-25?
More than 25, I think. I understand one turbine wheel is about 100K.
Super cool thank you.
thanks
God damn it, Gump! You're a god damn genius! This is the most outstanding answer I have ever heard. You must have a goddamn I.Q. of 160. You are goddamn gifted, Private Gump. Listen up, people... (Also, Thank you kindly for this amazingly clear explanation)
You are welcome. I think when we can visualize these things we can understand them fully.
What a great explanation! This video on pivotal altitude is a definite must see for anyone doing 8's on Pylons.
Thanks
@5:52 - Testing a plane battery - breaks out a near $2000, true 6 1/2 digit resolution meter and props it on a stool in the hanger. That is the fastest "like" i ever slapped on a video.
Thanks, glad someone recognized a Keithley!
Nice video !!! thanks
thanks
Congratz and thanks for the video! The explanation really helped now that I'll start flying this aircraft! Cound't find any better!
Thanks! I am sure you will love the Meridian.
Great video, thank you
thanks
Refering to the ITT I think you mesn TIT did you ?
Turbine inlet temp (TIT) is the temperature of the hot exhaust gas generated by a piston engine where it enters the turbocharger. We check TIT a lot in the Malibu to make sure we don’t roast the turbochargers. In the Meridian’s PT6 engine, we monitor the interstage turbine temperature (ITT) which is the temperature of the hot gas flowing between the turbine wheel that drives the compressor, and the first power turbine that drives the prop. We have to make sure the turbine wheels don’t get too hot. In both cases we are checking to make sure we don’t destroy anything with too much heat. For the PT6, ITT is the correct term.
Fantastic documentation, thank you very much! I'm not a real pilot, but I like to operate in my simulator as realistic as possible!
Thanks!
If you have to push the plane into the wind, how can you do that? Can this heavy plane pushed manually buy one person?
One person can't turn the Meridian around. It takes at least two. Line crews will usually turn it around with a tug.
Very well presented and informative. Thank you. Former DC8 driver
thanks
I'm surprised that P&W has not implemented a semi-automatic start procedure on the PT-6 which would protect the operator from a hot start.....
Dip voltage, or voltage under load for a car battery is 9 volts when the starter is running. The starter will cause a voltage drop of 3 volts. All cars with distributors in a 12 volt system have ballast resistors that keep the voltage in the ignition system at a constant 9 volts. When the starter is engaged and the available voltage for the ignition system drops to 9 volts current to the ignition system bypasses the ballast resister until the starter is released via the cars key switch. When it is released current is sent through the ballast resistor thereby maintaining 9 volts. An airplane such as the meridian uses 24 volts instead of twelve. If the airplane uses a piston engine I would expect it to run a ballast resistor like a car does. In a turbine engine, I don’t know if that is necessary, but that would explain the dip voltage that the creator of this video is talking about.
Thanks for watching my video. Not sure if this clarifies anything, but the ignition system in the Meridian is fully electronic. I believe the dip voltage is simply a result of the huge load of the starter motor as it begins to turn.
Just before 8 minutes, you state and show on your checklist that the pumps and ignition are set manual. Yet at 8:45 in the video the switches now appear to be selected to Auto. The lights still show manual, but the switch position now is selected on AUTO. When did you switch it to auto and why? Confusing.
When adding still images to a video to explain a detail or emphasize a point, I often don't have the exact photo I need and I have to improvise. In this case I used a photo of the switches that I had on hand, and changed the LEDs to green to indicate that they should be in manual mode. (I think the photo was probably taken in the hangar and the switches were physically in the off position.) When the engine is stable and idling with Ng around 64%, the fuel pumps are switched to auto and the ignition is turned off. Both go back to manual for take-off, then at 1,000 ft AGL they both go to auto.
The Pratt and Whitney Canada company is about 2 decades behind the times. That was when all the airlines had FADEC and one button starts, auto throttle for their engines and not risk a financial melt down. Other companies had to develop their own but P and W can get help from the US parent company, so dragging their feet is even more unacceptable. They can afford it because they have 70% of the small turbine market, but things are changing. It is like P and W on a railroad track, they have 3 choices, 1) keep up to speed of the traffic, 2) move aside 3) get run over. A few years ago, GE quietly bought a Cz company , Walters that made a PT-6 clone . They are initially working with Cessna for an engine to power their PC12 clone. Once that is done, I believe they be expanding their line. Since that just happened within the last 5 years, for decades more , many planes and chopper pilots still have to watch TIT temp like a hawk and be ready to cut off fuel.
The fuel control unit in the Meridian seems to be an old design that could be modernized, and maybe that will happen someday. Modernization comes slowly in aviation, but it is here to some extent in the M600 and maybe it will trickle down to the M500 and Meridian.
The TBMs 9x0 use PT6 and have a fully automated startup feature (as far as I know, I am no expert)
@@ImNotADeeJayIf the number start at "9" it is already a very new plane. 2017 or newer. I remember reading in magazine someone got an STC on an auto throttle for the PC12. You think with a parent company in US, the tech transfer would make FADEC much easier to add to the PT6, no, they just sat on their back sides for more than a decade.
you look like you use a mattress to floss your front teeth
Amazing video, thank you.
Thank you.
Well done! One of the better videos on this important subject. I suggest any PA-46 Owners or prospective owners join MMOPA. Lot sof useful info and guidance there. There is also a "Tow Limit Placard" for sale that can be attached to the nosegear when parked that highlights the turn limits.
Thank you!
We are about to acquire a PA-46 .. do you advise line personnel of the towing limitations? Also Ed N. is THE guy. We won't use anyone else.
Yes, I always talk to the line person if I don't know for certain that the FBO is familiar with the PA46 turn limits, and if possible I observe. I find a good tip ($10) also helps, and is cheap insurance. E.N. is excellent, and there are a few other people who are also very good around the US.
Mark thanks for that informative video.👍
Thanks, glad you found it useful.
This is the best video I have seen, as a student pilot this is the plane I'm going buy once I get more fight time
thanks!
🛩️🛩️🛩️👏👏👏👏👏👏👍
thanks
Thanks for putting together such a thoughtful and detailed explanation. My Pilatus on-boarding never mentioned certain nuances like wind direction at start. Very nicely done, thank you.
Glad it was helpful!
99.999999999% sure I will NEVER own or operate a turboprop. However, IF I do, this video is officially my start sequence bible (even if the aircraft is equipped with a FADEC engine)!
Thanks!
With FADEC, you can forget much of this video. Pratt and Whitney is about 2 decades behind the times.
Ok and they are a goood item to have at times. You want to keep that turbocharger “warm” amd don’t “shock the engine”
Don’t you have speed brakes ? (For your descent )
No speed brakes on the original Malibu. I think they can be added with an STC, but N9109M did not have them.
I am a virtual pilot on Xplane and I don't even think I will ever own any PT6A engined airplane but I understood every bit of these instructions. Very good teacher and wishing you a very Long Life. Salute, Captain.
Thank you!
Is it true to say that the radius of the turn stays the same given that the airspeed stays the same? The only thing that changes here is the ground speed which doesn’t affect the actual radius of the turn but just the reference line because you are looking at the ground.
The analysis presented is for the no-wind case, so airspeed and groundspeed are the same. If we fly in a circle at a constant speed and altitude, the radius will be constant.
You called it dip(?) voltage, I never had a name for it but after turning on the battery switch I didn’t want the voltage to drop below 24 VDC with a NiCd battery, because of the discharge characteristics of the battery, when switching to lead/acid gel batteries I could get away with lower initial voltage. On initial starter engagement if the voltage dropped and didn’t start recovering, it was abort time and find an apu. Healthy start had N1 stabilizing above minimum and battery recovering. After start pay attention to voltage the longer it stays above 28 the sicker the battery is. I much rather start a turbine with PAS air.
It is all about trying to get a handle on the health of the lead/acid battery before adding fuel. The initial bus voltage when I turn on the battery master gives me an estimate of the whether the battery is fully charged, and the "dip" voltage under the huge load of the starter motor is an indication of how much total energy is available. You are right that the voltage does need to start recovering. These are only rough estimates of battery health, but I know that if voltage is low, or the voltage does not recover, there might not be enough juice to avoid a hot start, so in that case I would abort.
I've seen people start a PT-6 with someone holding one of the blades from moving
I don't know why, but with a free turbine, you can do it.
Looks similar to a PA32 Lanceair
Half a million for an engine...my head spins
Yeah, I know! It took me a 10 years to decide to fly a plane with that much value hanging on the front. That's why we have to be so darn careful not to hot start it (hot starts are generally not covered by insurance).
Thank you for putting together this video. Very good and informative. You covered Bat Voltage, health way better than Ive seen it at expensive training. What I do different is. During start, I allow the starter Ng to stabilize before introducing fuel, this shows me the capacity of the battery. I have personal limits. I want min 18% but a Cold battery, lower voltage, Ill except lower but next warm start should be back up. If a storm is coming 14%, Tornado 12.5%. If introducing fuel at 12.5 - 13% Ng, A weak, low capacity battery may drop voltage after light-off and could be hidden. As you stated Voltage Sag, or Dip shows battery health but nothing compares to Work (= Ng %) after a few seconds. The other thing is I, Count seconds after introducing fuel. Light off should happen at a consistent time. ie 4-5 sec, if no light off I continue to 10 sec, Fuel off, Starter off, WTF.... Having the set time and shut down procedure reduces the (oh shit I forgot the ignitors! On, Boom, Hot start. Take it for what its worth. Nice plane.
Those are all good ideas, and thank you for the detailed comment.. The only reasons can think of not to wait for Ng to stabilize as high as possible before introducing fuel are (1) there is a time limit on running the starter, and (2) if the battery is a bit weak, it may be better to light the fire as soon as possible to be sure there is enough juice to keep the starter running and the start cool. Thanks again.
Checklists is always top notch in all aircraft
Great point in knowing this about starting into the wind or as you say seeing the prop moving
Thanks!
Thanks so much for a great video! New to the channel and new subscriber!
I m glad you enjoyed the video.
BRILLIANT ABSOLUTELY BRILLIANT
Thank you!
How high can this aircraft fly?
The Meridian certification ceiling is FL300 (30,000 ft), and that also requires RVSM cert (which N555GP has). Without RVSM cert. the highest legal altitude is FL280 (28,000 ft).
Great video. Very detailed. Safe travels.
Thanks
