Beechtalk – bt – aerostars what is anoxic encephalopathy

I pick up my new (to me) aerostar 601P and start the training on the 3rd.

Beyond the options required by A/D (fire detect etc…)

It presently has intercoolers, the short props and six puck brakes.

I’ve already got a GTN750 and GTX-345 lined up as an upgrade.

After than I’m going to add the FIKI kit.

I’d love owners comments on:

Winglets: they look awesome, but do they really add any performance?

One of the reasons I choose an aerostar over something like a cheyenne is the ability to

Stay low and look at things without having a huge fuel penalty.. Do the winglets cost you any performance down low? Clearly their gain is at higher angles of attach, ie at altitude and slow….


Bleed air heat?

Is the 5.5 PSI really that useful for a 601P?What is anoxic encephalopathy

Paul,

I have a 601P, and in the eyes of some, am the poster child for getting the latest and greatest of AAC’s aerostar’s mods.

Other’s are likely to have different opinions.

First, the one option that ought to be the first one you do, is the electric door seal mod.

If your new plane doesn’t have it, get it.

Second, before (or concurrent with) doing any other avionics work, plan on installing, at least a JPI 760, and get educated on what it can tell you.

The rest of this is just one man’s opinion:

1. FIKI…. This is going to be inner boots and controllable alternate air doors, and maybe an electric plate for the windshield.

In my opinion, all one needs to get out of icing conditions is working hot props, to see, the alcohol spray does an OK job, and avoids one having to look through the plate, the boots help, but one definitely does not want to attempt to use them to hang out in icing conditions, actuating boots is just like pumping up the door seal, hard on the pneumatic pumps), do a lot and a pump is going to fail.What is anoxic encephalopathy

The alternate air may have some merit, but the ice screens (simple and inexpensive) do an OK job reducing engine surges in ice, and don’t open the door to bringing exhaust into the cabin. In 10 years of ownership, I haven’t canceled a flight because I only have boots, props, and alcohol W/S.

2. LOP operation.

With GAMI’s (set up correctly) you can operate a 601P LOP.

Max power up high is going to be limited to less than 60% by TIT temps (you’ll see on your JPI).

The lower power available LOP, especially heavy, will put you on the reverse slope in terms of the drag curve, which is a huge PITA. Winglets fix this issue and increase cruise speed 10+ KTS. Your climb at 140 (not so much at vz) will improve.What is anoxic encephalopathy

I operate LOP almost all the time, in cruise, I love the winglets.

However, if YOU are going to operate at 27 x 2,200 (75%), the winglets won’t make much difference in cruise speed. To my knowledge, the winglets do not cost performance at any speed, you just won’t get as much benefit as you would at lower indicated air speeds. The winglets ought to improve S/E ROC, which in a 601P is a big deal, however I do not have any data on this.

3. In the past I experienced problems with my janitrol, and my passengers froze, even when it is working, it leaves a smoke trail on the tail. The bleed system does as good a job as the janitrol at high maps, when the turbos are compressing air, coming back the other night at FL210 (-18C), I was comfortable in a long sleeve shirt using the bleed heat, I used the janitrol on the ground, and on my descent because I had it, and it was easier than being cold, or putting on my jacket.What is anoxic encephalopathy I like knowing that I have a bullet proof heating system.

4. I have the 5.5 pressurization, I justified it in that my W/S was coming up on time, and I operate at higher fls whenever possible and was noticing minor hypoxia symptoms after running high for a few hours, with the 5.5, I feel great after a long high trip. Definitely worth what it cost.

Welcome!

Thanks for the detailed response…

I already have the electric aux hydraulic pump. (is there any aerostar without this?)

I have the electric door seal pump…

As part of purchasing the aircraft I had them add a JPI-760 with probes on all four turbos

what is anoxic encephalopathy

(these are all already done)

After I have the airplane for a little while I’ll see what the LOP spread is and will probably purchase GAMI’s….

The airplane has the aztec electric window plate, so even with the FIKI kit I would not be legally FIKI unless I replaced the plate with the the aerostar electric window… Alas I’m part 91 and the aztec plate is FIKI on an aztec….YMMV I was more interested in the alternate air part of the FIKI kit than I was for boots on the inner wing…. Will look into ice screens… One of the reasons to upgrade toe the aerostar was to go to northen cal and oregon in the winter where ice forecasts have canceled some of my planned flights in the travel air.

Your thoughts on the winglets echo mine, only really help at high angles of attack…What is anoxic encephalopathy

OEI climb might be a big deal, alas the home airport is at 330ft so not as big a deal as it would be in denver…..

The gas heater on my travel air has been flawless and hot enough to keep things warm…..

Given that it, the engineer in me sees that it makes no sense to cool air with the cabin inter cooler just to heat it back up again….

Aerostar question — forrest what do you think?

Today I flew my 700P and I took off for a 45 minute flight with 80 gallons on board. I had 22 in the main and 34 in each wing. After I flew about 30 minutes the main went below 10 and I got a low fuel light. I still had 22 or so in each wing but it looked like the main was dropping a lot faster.What is anoxic encephalopathy I put it in double crossfeed until final and did not have an issue. I don’t remember seeing that much still in the wings but having the main drop down. Is that a problem? I got concerned that I would empty the main and still have fuel out in the wings. Is that even possible? I have about 1000 hours in the plane now and today was my first low fuel light.

Eric,

Yes possible. I had the main drain much faster then the wings on the first flight of my aerostar actually, I even had the seller with me (we were flying it to AAC for some work). Both the seller and jim christy at both said either the vent lines were plugged or leaks at the gas caps. Start with the easy one and replace the o-rings on the gas caps.What is anoxic encephalopathy

No idea, if these are the only causes; just apparently the common ones

Is there still a high noon meeting at the OK corral planned between forrest and JGG to resolve some of this?[/quote]

No.

All that talk about money scared me off.

Only way I’d come to play is if someone commits to cover the beer bill for bob and me and whoever volenteers be the the other guy.[/quote]

To all readers of this thread:

The banter about winglets was just that: banter. Neither forrest nor I were being aggressive or mean spirited about the debate. In fact, we exchanged PM’s on the back side talking about family and a possible visit by forrest while it was going on.

The third party insertion of money was completely inappropriate and took a playful banter to what would have been a very embarrassing showdown for all involved.What is anoxic encephalopathy

Tom had already said what he saw as improvements with winglets and that they came with a small penalty in speed. I am betting his observations are accurate.

That being said, if anyone took it too far, it was me, and I have apologized profusely to forrest in a PM. I extend that apology to anyone that I offended. Faceless communication has its limits. The written word is only a small part of the communication venues that we, humans, use with one another. Voice inflection, tone, volume, facial expressions and body posturing conveys the majority of our message. I, of all people, should know that and I fault absolutely NO ONE but myself for allowing the winglets debate get out of hand.

Again, I apologize.What is anoxic encephalopathy profusely!

You are welcome.

Keep in mind, a pressurized aerostar can easily fly over icing conditions that would plague a travel air.What is anoxic encephalopathy

Aside from the whole legal to go (in a non-known ice airplane) debate over forecast icing, it is very doable to remain above icing conditions (light rime or clear) until close to one’s destination, and then descend (rapidly) through those conditions (into temps above freezing).

The key is knowing that when you start to descend you can get to temps where the ice will melt in one shot. ATC is understanding about an aircraft making this request (and about you not wanting to remain in suspected (likely) icing conditions, but you will need to be situationally aware enough to know where/when you’ll want to start down.

I have heard stories (and seen pictures) of ice carried by aerostars, but I haven’t been one to explore that end of the envelope.What is anoxic encephalopathy

A few years ago I attempted to make it from grand strand to norfolk by going under and staying below the freezing level crossing an occluded front.

It is was going to be a close thing as the front was moving east with freezing rain and snow, FSS was optimistic, I figured: what the heck, I can always do a 180 back to better weather.

I kept descending to get out of ice, until I could not go lower and remain with ATC (I was IFR), and then passing kinston, NC that wasn’t low enough.

Freezing rain, clear ice.

Well heck.

Ended up landing in kinston, and as the alcohol couldn’t clear the W/S ended up using the camera to get lined up on the R/W. Plane flew OK covered with 1/2 of clear ice, opening the door was a bit of a challenge as I had to break ice to open it, the ramp was a sheet of ice.What is anoxic encephalopathy

Then I really screwed up and rented a car and continued on to norfolk, into a blizzard/ice storm.

We made it to edenton, where every place that sold food and drink except the CVS was closed, next day drove to norfolk, and the following drove back to kinston.

We could have spent a fun night in grand strand, instead it was smoked almonds and whatever at the bed (sorry, no breakfast) in edenton. I still hear about that trip.
