The Go Around Button

0 Comments

Back in the old days, when flying an approach in an early Cirrus SR22 (circa 2004; yes, in airplane technology, those were the old days), performing a missed approach procedure was a lot of work.  You were low to the ground, weren’t able to see the runway, then you had to start climbing so you don’t hit the ground, then push a lot of buttons in order to get the GPS and autopilot set fly the missed approach procedure.  It was very easy to get distracted with button pushing, then forget to fly the airplane, putting yourself and passengers in very unsafe circumstances.  The go around button has changed all that.

Going Missed the Old Fashioned Way

Let’s stick with our example of the 2004 Cirrus.  The SR22 in 2004 was equipped with the Avidyne Entegra system, complete with dual Garmin 430 GPS units, and an STEC 55x Autopilot.  A very capable IFR flying machine (we could use the same example of a 2004 or 2005 Lancair Columbia 350 or 400 that was equipped the same way, except the screens were vertical instead of horizontal).

Avidyne Cirrus Go Around Button

We’ll use the ILS 15 at the Temple airport, KTPL, for our example.  You pass TPL, the outer marker at 1,683 with the glide slope already centered.  Everything is going well so far.  The number 1 Garmin 430 is set to VLOC and the autopilot is showing NAV and APR for the lateral guidance and GS on the vertical, tracking the glide slope.  The last weather report stated the clouds were Broken at 500 feet, so it appears like you’ll be able to get in on the approach.

As you get closer to the Decision Altitude, the clouds aren’t letting up at all.  You hit 1,000 feet on your altimeter, 120 feet above the minimums, and you still can’t see a thing.  Another 100 feet lower doesn’t change anything, so you elect to proceed with the missed approach.  This means things are about to get busy.

Here’s the process:

  • Fly the airplane first, meaning shut off the autopilot, pitch the nose up, add full power, retract the flaps, and step on the right rudder
  • The Garmin 430 is now in SUSP mode, meaning the missed approach point is locked in as the active waypoint.  So, you have to press the OBS button to cause the GPS to cycle over to the missed approach procedure
  • You have to press the VLOC button on the Garmin 430 in order to change the CDI back to GPS
  • You have to re-engage the autopilot by pressing NAV twice (which engages GPS Steering mode)
  • You have to reset your altitude bug (if you hadn’t set it for the missed approach altitude previously)
  • You have to press VS and ALT on your autopilot to have the STEC continue the climb

That’s a lot of work, isn’t it?  Plus, that’s an extensive amount of head down time in the cockpit, with your eyes looking elsewhere other than the instruments while hand flying.  All very low to the ground, I might add.  Can you see how this can be dangerous?

The advent of the Go Around Button has streamlined the process, leading to safer operations where it matters most.  The functions of the Go Around Button vary based on the airplane, but here are two examples, the Garmin G1000 Cessna Corvalis TT and the Garmin Perspective Cirrus SR22.

Cessna Corvalis TT

We’ll take the above situation and swap out the airplanes.  Gone is the 2004 Cirrus SR22.  Insert a 2009 Cessna Corvalis TT, equipped with the Garmin G1000 suite and the GFC 700 autopilot.  The go around button is positioned directly above the twist in throttle.

When you push the Go Around Button, here’s what the system does:

  • Disconnects the Autopilot
  • Sets the Flight Director for 7.5 degrees pitch up (which is about your normal climb angle) and wings level
  • Switches the CDI back to GPS
  • Takes the GPS out of SUSP mode and cycles the flight plan to the first waypoint on the missed approach procedure

Here’s what you have to do:

  • Follow the flight director by pitching the nose up
  • Add full mixture, prop and throttle
  • Retract the flaps
  • Step on the right rudder
  • Re-engage the autopilot, then press NAV and VS (or IAS) and set your altitude bug if it isn’t already set

Not too bad, eh?  Makes the whole situation streamlined and safer.

Cirrus SR22

Cirrus Perspective Go Around Button

Same situation, different airplane.  This time, we’ll use the 2010 Cirrus SR22T with the Garmin Perspective and GFC 700 Autopilot. One thing I really like about how Cirrus configured their system is where the Go Around button is.  It’s actually on the throttle itself, making it much more intuitive.  This way, you can press the Go Around button while adding full throttle.

There is one major difference between the Garmin Perspective in the Cirrus and the G1000 in the Corvalis.  When you press the Go Around button in the Cirrus, the autopilot actually stays on.

Here’s what happens when you press the Go Around button in the Cirrus:

  • Flight Director pitches to 7.5 degrees pitch up and wings level
  • AP Mode switches to Go Around mode, following the flight director
  • GPS comes out of SUSP mode
  • CDI switches back to GPS

All the pilot really has to do is add power, take the flaps up, then press NAV on the GFC 700 to get the autopilot following the missed approach procedure.

If you aren’t familiar with the Go Around button or haven’t used the one in your plane lately, it’s good to go up with a knowledgeable instructor and fly a couple of approaches where you perform the published missed approach afterward.  That way, he or she can assist you through the first missed approach, then give you pointers until  you get comfortable with the Go Around button.

Aircraft Purchase: The Logbook & Pre-Purchase Inspections

1 Comment

Your about to make your dream aircraft purchase.  The plane has low time on the engine, is reasonably priced, and, according to the seller, has no damage history.  You are overjoyed!  Your dream of making an aircraft purchase is finally coming true.  You prepare your offer for the seller, set up the escrow account, and start all the paperwork.

Two weeks later, the airplane is yours!  You start flying it, though, and the engine starts to have some strange vibrations.  After several flights, it starts to get worse.  You take it to your mechanic to get it looked at and you find out the airplane needs three new cylinders along with some other engine work that is going to total a lot of money.  Plus, your airplane is now going to be in the shop for several weeks.

All that excitement you just had?  It just went out the window.

Could this have been prevented?  Probably so, with a logbook inspection and a pre-purchase inspection.

Aircraft Purchase:  Maintenance Logbooks

Aircraft Purchase: Logbook Inspection

Inspecting a logbook can be very daunting when making an aircraft purchase, especially for older airplanes.  This is, however, one of the most vital steps in making a new aircraft purchase.  You can find out many things from looking at the maintenance logs of an airplane.  First, you can check the compression levels of the engine.  Typically, you want compression levels in the 70’s, with it still being okay in the high 60’s.  Anything below 65 and there could be potential problems.

Second, you can find out if there has been any odd maintenance done pointing to possible unreported damage history.  This is rare, as most aircraft owners are honest and up front when talking about damage history.  But, if there is an entry detailing a prop overhaul after only 50 hours on that prop, you may start to ask some questions.

Third, you can find out how well the airplane has been maintained.  If a lot of maintenance was completed at each annual, even if it was a lot of small things, then the airplane has been maintained by a good mechanic who is very thorough.  This also involves a check of the ADs, Mandatory SBs, SBs, and SLs that have been issued for the airplane.  If all that has been kept up with, it’s a well maintained airplane.

Finally, it gives you a good idea of how much the airplane has been flown.  Sure, the ad online will have the total time and time since overhaul, but you can look at the year by year breakdown of how much the airplane has been flown.  It may have been flown a lot earlier in it’s life, but not quite as much recently.  That’s not necessarily a bad thing, but airplanes like to be flown.

Aircraft Purchase: Pre-Purchase Inspection

Before making an aircraft purchase, it is extremely vital that whenever you are buying an airplane that you get a pre-purchase inspection done on the airplane.  Even better is getting one done by a mechanic who specializes in that type of airplane (eg. Piper Service Center for Pipers, Cirrus Service Centers for Cirrus, Kevin Mead for PA-46s).  A pre-purchase inspection can save you a lot of money in the end.

There is always going to be some kind of maintenance issue with an airplane being purchased, whether it is big or small.  Once a pre-purchase inspection is completed, you can take the findings to the seller and negotiate for a lower price based on those findings, or just have the seller fix the items before the sale is completed.

I would recommend having the seller fix the problems before the sale is completed.  Even though it may take a little longer for the sale to be completed this way, you’ll get to enjoy your airplane right away instead of it being in the shop the next several weeks after you complete the purchase.

There is the circumstance where the  pre-purchase inspection reveals some serious airworthiness issues which would cause the deal to be voided.  Always put this clause in a purchase agreement, giving you, the buyer, an out if there are serious airworthiness issues.

When it comes to making an aircraft purchase, it is not a process to be rushed.  Slow and steady usually gets the best airplane for the money, giving you years of enjoyment in the future.

The Piper Saratoga Turbo

0 Comments

Piper SaratogaRecently, I assisted with the delivery of a 2007 Piper Saratoga Turbo from San Antonio to New York City.  It was a very nicely equipped airplane, complete with a Garmin G1000 panel, an STEC 55x autopilot, and air conditioning.  The owner joined me on the flight back to get trained in the airplane, getting him comfortable in it over our 2 day excursion back to NYC.  Total flight time was 12 hours, though that did include several stops along the way and landing practice at the airports we stopped at.

The 6 seat Turbo Saratoga is a very comfortable, very capable flying machine.  It is made for hauling, with a gross weight of 3,600 pounds, but that’s not to say it isn’t lacking in comfort, either.  The rear cabin has 4 seats, 2 facing forward and 2 facing rear.  It would be a little tight for 4 full size adults in the back seat.  To avoid knee knocking, the plane is an excellent 4 person and bags aircraft (or 4 adults and 2 kids).

The really nice part about the Piper Saratoga is the baggage door.  Unlike the Bonanza, the Piper Saratoga has a baggage door that opens to the baggage compartment, creating a much easier way to load and unload baggage.  The nose baggage compartment, which holds an additional 100 pounds, is a very nice feature, allowing the bag load to be spread out.

Piper Saratoga Inside

We typically saw cruise speeds of 155-165 KTAS depending on altitude.  The highest we went was only about 9,000 feet, so we didn’t get up real high to see what the single turbo could do.  Even though the Lycoming TIO-540 engine burns about 20 gallons an hour, with 102 gallons of gas on board, the fuel consistently outlasted our desire to continue flying.

Being equipped with the G1000 was a very nice feature of this particular Piper Saratoga.  The screens are nice and big, larger than the displays on a high wing Cessna or a Corvalis.  That allows for easier viewing of approach plates, NEXRAD, and the engine gauges.

There are always downsides to an airplane, and the Saratoga is no exception.  The STEC Autopilot leaves some to be desired as I felt it hampered the capability of the G1000 when shooting approaches because the 12 knot crosswind limitation on the autopilot. You can still use the autopilot on an approach with higher than 12 knot crosswinds, but the autopilot tends to search around for the final approach course.

The air conditioning works very nicely, though it did have a tendency to freeze up at altitude.  We discovered that quickly and just decided to turn it off and leave the blower on, since it was cool enough up high anyway.

Overall, the Turbo Saratoga is a very nice airplane.  The speed leaves a little to be desired (you can get 10 KTAS more out of a Bonanza with a Continental engine, about 20 knots more if it is a Turbo Bonanza), but it is very high on comfort.  The Piper Saratoga makes for a good family airplane or as a hauler.  I liked the airplane a lot and thoroughly enjoyed my time in it.

New Houston Airspace Procedures

1 Comment

If you are based in Houston, or heading into or out of the Houston airspace under IFR, have you updated your charts?  If not, you may hear a clearance stating: “N67889, cleared to Amarillo via the BORRN 1 Departure, CRGER Transition, Direct.  Climb via the departure, expect 8000 in 10 minutes.  Departure frequency 123.8, Squawk 3365.”  You manage to get the clearance written down, but have completely messed up the spelling of both BORRN and CRGER, so you have no idea where the intersections are.  After stumbling through a readback, you ask ground to spell the fixes for you.

Then, more bad news.  You haven’t updated your GPS cards yet, so the departure isn’t in your 430.  It’s an RNAV only departure, so you can’t fly it based on the NAV Radio.  You were planning on updating your iPad when you got to Amarillo, so you don’t have the departure on there, either.

This has probably already happened to a few people today already.

Houston airspace got a major overhaul today.  There are 20 new DPs and 29 new STARs guiding IFR traffic into and out of Houston airspace (including one named the DOOBI 1 Arrival, named after the Dooby Brothers band).

The FAA’s goal in all these changes, according to AOPA, is to “bring fuel efficiencies, time efficiencies, and reduce carbon emissions” (from Benet J. Wilson’s May 15th article on AOPA.com).  The FAA issued a NOTAM today valid until June 6th describing what routes for pilots to file.  The NOTAM also contains contingency plans for pilots flying without updated charts (like our example above).

Pilots should expect these wide scale procedure additions and changes to start showing up in other Class B airspace across the country.  As always, make sure those charts are updated, GPS databases are current, and you do some studying of your route before you file your flight plan.
