Flight Service Station

ByHank Gibson

When is the last time you talked to the Flight Service Station?

Believe it or not, FSS is still in existence.  Over the past 10 years, they went from FAA run, the being bought by Lockheed Martin, to now being privately run by a company called Leidos. 1-800-WX Brief will get you connected with a weather briefer, but you’ll hear “Leidos Flight Service Station” now when the briefer picks up.

Since the advent of Foreflight, most pilots these days get their weather briefings digitally on the iPad. Foreflight has come a long way since it’s inception.  The briefing part of their Flights page is quite comprehensive, with lots of information, and counts as a legal weather briefing (which pilots are still required to get before a flight).

Why does a pilot even need to call Flight Service?  Well, when’s the last time you tried to interpret everything the Briefing on Foreflight told you?  As I said before, it’s a lot of information and a lot of it can be confusing.  Pilots are not fully trained on interpreting Prog Charts and getting an overall weather picture for a flight.  A weather briefer is.

I have over 5,000 hours and I still call a weather briefer before almost every flight.  On the way to the airport is a great opportunity to get a weather briefing.  I get a great picture of what’s going on in my area or over my route, frontal movement, bad weather areas, and whether or not it’s a good idea to even take off. Calling in the car alleviates the main complaint I hear about calling the Flight Service Station, which is it’s inconvenient and causes a delay since you have to call them on the phone.

I don’t do much private pilot training anymore, but when I do, I always teach my students how to get a weather briefing from the Flight Service Station.  I’ll show them how to get the briefing on Foreflight too, but usually their eyes bug out of their heads when they start trying to read everything.  A breathe of relief is released when I tell them there is a trained professional just a phone call away who can clear everything up.

The other thing that the Flight Service Station provides that is important to a lot of folks are PIREPs.  It’s vital in sketchy weather areas for the FSS to get a report of what’s actually going on in the air.  This helps other pilots out greatly as they are getting information about icing, cloud bases and tops, turbulence and a myriad of other things from airplanes who are actually in the conditions.

Finally, the most used portion of the Flight Service Station is the Clearance Delivery line (888-766-8267). At airports without a tower or a clearance delivery frequency, with IFR conditions present, the only way to get your IFR clearance is to call Clearance Delivery.  Yes, it can take a little time sometimes, but you will get a clearance every time, unlike taking off and trying to dodge the clouds without hitting anything, while trying to call Center on the radio (which isn’t safe or legal).

Been a while since you’ve talked to the Flight Service Station?  Give them a call, either on the phone or on the radio.  Odds are, they are bored and just wanting someone to talk to, just like you are on that long cross country flight!

  • Flying WAAS GPS Approaches

    ByHank Gibson

    When flying a WAAS GPS approach, there are several different levels of WAAS signal that a GPS receiver can get. The most precise is an LPV signal. LPV stands for Localizer Performance with Vertical guidance. An LPV approach has the lowest minimums of all the WAAS GPS approaches, typically in the range of 200-300 feet AGL. A GPS glide path (GP) is guaranteed with an LPV approach and the minimum altitude is a decision altitude (DA).

    Just like a localizer, an LPV course width get’s tighter and the CDI becomes more sensitive the closer the plane get’s to the runway. Even though the LPV approach minimums are so low and the approach is down to a DA, they still aren’t considered precision approaches by the FAA (which leads to some extra planning when selecting an airport as an alternate that only has GPS approaches, since the AIM specifies only the LNAV minimum are to be considered if an alternate airport only has GPS approaches, bringing the 800 foot ceiling requirement to bear)

    An LNAV/VNAV approach is still a WAAS approach that has a GPS glidepath, but is slightly different than an LPV approach. An LNAV/VNAV final approach course does not get more sensitive the closer the plane gets to the runway. The smallest course width on an LNAV/VNAV approach is 0.3 miles either side of center. LNAV/VNAV approaches will, most of the time, have higher minimums than LPV approaches and can have minimums no lower than 250′ AGL.

    The third type of WAAS approach is strictly a non-precision approach with a Minimum Descent Altitude (MDA). These are designated LP approaches, which stands for Localizer Performance. These are like old school Localizer only approaches that, similar to the lateral portion of an LPV approach, the course width tightens the closer to the runway that a pilot is. There is no glide path by definition of an LP approach, though there is a caveat.

    Now, by looking at an approach plate that is a WAAS approach, but only has LP minimums listed, a pilot would assume there would be no glide path. Depending on what type of GPS unit the airplane has, that pilot could be wrong. Garmin Perspective units (Cirrus G1000), all GTN 750s and GTN 650s, All G1000 NXi units, most Garmin 430W and 530W, and all Avidyne IFD 550/540 and 440 units will display an advisory glide path on an LP approach, designated LP+V.

    What does LP+V indicate? An advisory glide path is just advisory, but it is totally legal to follow down on a non-precision LP approach. The kicker is obstacle clearance is not guaranteed and the pilot needs to keep an eye on minimum altitudes at the different waypoints on the approach. The big thing I tell people is, when you arrive at the MDA and the runway is in sight, following the advisory glide path below the MDA could get you in trouble with obstacles. Don’t just hone in on your instruments when you break out of the clouds. Look out the windscreen and make sure you won’t hit anything.

    If you arrive at the MDA on the advisory glide path and the runway isn’t in sight, DON’T GO BELOW THE MDA! Most autopilots won’t level off at the MDA, even if that altitude is set in the altitude pre-select, so this will involve turning off the autopilot before the MDA and manually leveling off, or engaging the altitude mode of your autopilot at the MDA.

    One other type of GPS approach that you will encounter is an LNAV approach. This is a non-WAAS approach down to an MDA, but your GPS unit may still give you a +V. Most modern ones will.

  • Flying the Piper Malibu

    ByHank Gibson

    Looking for an airplane with more seats, more useful load, and good speed?  Look no further than the PA-46-310P Piper Malibu.  It feels like a corporate airplane, but this turbo charged piston single is good owner/pilot airplane for taking the family on vacation or using on business trips.

    Piper Malibu Texas Top Aviation

    The original Piper Malibu, which was manufactured between 1984-1988, is a great next step airplane for Cirrus owners, Saratoga or Lance owners, and Mooney owners looking to move up to a pressurized, 6 seat piston.  The pressurization has got to be one of the best parts of the Piper Malibu.  The ability to climb up to the low flight levels (the service ceiling is FL250, but the airplane performs great between 16,000 and FL190) to catch better winds and get a better true airspeed (the airplane gains about 2.5 KTAS for every thousand feet) without having to wear oxygen makes the ride much more enjoyable.

    Equipped with six seats and a 4,100 pound gross weight, the Piper Malibu allows for a lot more carrying ability than a Cirrus or even a Saratoga.  Now, like most piston airplanes, you can’t take 6 average adults, bags, and full fuel, but here’s the great part:  the Continental TSIO 320 only burns 16.5 GPH in cruise at 75% power.  The plane will still fly 200 KTAS at 16.5 GPH.  With 120 gallon capacity, even taking half tanks still allows for a 2.5 hour range with an hour reserve.  At 200 KTAS, that’s 450 miles.  And, you gain an extra 360 pounds useful load at half tanks.  That’s not too shabby.

    Piper Malibu PA-46 Texas Top Aviation

    The Piper Malibu was designed to be comfortable, fast, and be able to carry some baggage.  There are two baggage compartments, one in the nose behind the firewall and one in the rear behind the rear seats.  The nose baggage is wide enough to fit golf clubs in, while the back baggage is large enough to fit rolling suitcases in (the front baggage has no problem with roller bags either).  Lots of weight in bags?  Again, no big deal.  Just plan on taking less fuel and still flying for 2.5 hours.

    From a pilot’s standpoint, the Piper Malibu is a pretty straightforward airplane to fly, though it does require some specialty training.  A lot of PA-46s on the market right now have upgraded glass panels and digital engine monitors, making piloting the airplane that much more streamlined.  Most Piper Malibus are equipped with the KFC 150 autopilot.  Some have a yaw damper installed, others don’t.  Some have the vertical speed and altitude capture installed, others don’t.  It just depends on that specific airplane.  They aren’t like a Cirrus where they are all made the same.

    Looking to upgrade to something with more seats, a higher service ceiling, but not a significant increase in fuel costs?  Look into the Piper Malibu.  You can get one in good shape from about $300,000.

  • Garmin GFC 700 Autopilot

    ByHank Gibson

    The Garmin GFC 700 Autopilot is an amazing machine.  Fully digital and fully integrated with the Garmin G1000 glass panel, it makes a pilot’s workload a lot easier, especially in busy airspace.

    I train a lot of pilots in airplanes that have the Garmin GFC 700 autopilot.  The Cirrus SR22, the Columbia 350 & 400, the G36 Bonanza, and the Piper Mirage and M350 to name a few.  The most common problem I see for pilots transitioning into the Garmin GFC 700 equipped aircraft is that it doesn’t act like other autopilots.

    STECs and DFC 90 Autopilots function like this:  you push the button for the mode you want on the autopilot controller and that turns the autopilot on.

    Not so on the Garmin GFC 700.  If you push the button for the mode on the GFC 700, then the flight director engages, but not the autopilot.  This confuses folks a lot who move up from different autopilots because their autopilot primacy side of their brain is telling them the autopilot is on whenever they push one of the buttons on the GFC 700 controller.

    Here’s an example:  A pilot has just departed and is ready to turn on course.  In his old airplane with an STEC 55x autopilot, the pilot pushes the direct to key to go to his first waypoint, then pushes NAV on the autopilot controller and the STEC 55x comes on and starts flying on course.  Then he presses VS and ALT to initiate a climb.

    With the same scenario and a Garmin GFC 700 autopilot, the same pilot (who is used to a 55x), pushes the direct to key, then pushes NAV on the autopilot controller and pushes IAS or FLC to initiate the climb.  He lets go of the flight controls thinking the autopilot is engaged.  The airplane starts nosing over and he starts panicking.

    Why did this happen?  The pilot in the second scenario never pushed the AP button on the Garmin GFC 700 so the autopilot never engaged.  All he did by pressing the NAV button and IAS button was to turn the flight director on.

    How to remedy this?  Get in the habit of checking your scoreboard.  On the top of the G1000 or Garmin Perspective PFD, there is an autopilot annunciation strip (or scoreboard as I like to call it).  In the very middle of the scoreboard is an area to show if the autopilot or flight director is engaged.  AP means the autopilot is on; FD means the flight director is engaged but the autopilot is not.

    I teach pilots to be in the habit of checking your scoreboard each time you get done pressing buttons on the autopilot controller to ensure the Garmin GFC 700 is in the proper mode.  This saves some of those panic moments when it is supposed the AP is engaged, but it’s only the FD.

  • Contact Approaches

    ByHank Gibson

    Almost all IFR pilots are familiar with visual approaches and what the requirements are in order to fly a visual approach. As a refresher, the Instrument Procedures Handbook defines a Visual Approach as “an ATC authorization for an aircraft on an IFR flight plan to proceed visually to the airport of intended landing; it is not an [Instrument Approach Procedure]” (page 4-56).

    For ATC to issue a Visual Approach, the pilot must have the airport or the traffic to follow in sight. Once the pilot reports the airport or the traffic in sight, ATC can clear the aircraft for a visual approach.

    A limiting factor for a visual approach is ATC’s Minimum Vectoring Altitude. “This altitude, based on terrain and obstruction clearance, provides controllers with minimum altitudes to vector aircraft in and around a particular location” (Instrument Procedures Handbook page 1-42). ATC has to restrict aircraft to these MVAs, which can sometimes be quite high due to terrain or obstacles in the vicinity of the airport.

    Every pilot has been in a situation with a high MVA that ATC can’t get them below, but it’s solidly MVFR or VFR at the destination airport. The MVA keeps the pilot in the clouds, so a visual approach isn’t possible since the pilot can’t see the airport or the traffic to follow. This can lead to extra time to go out and fly an approach.

    Enter a Contact Approach. A Contact Approach is different then a Visual Approach. “The main differences between a visual approach and a contact approach are: a pilot must request a contact approach, while a visual approach may be assigned by ATC or requested by the pilot; and a contact approach may be approved with 1sm visibility if the flight can remain clear of clouds, while a visual approach requires the pilot to have the airport in sight, or a preceding aircraft to be followed, and the ceiling must be at least 1,000 feet AGL with at least 3sm visibility” [Instrument Procedures Handbook page 4-57].

    Here’s the simplified explanation: A pilot does not have to have the airport in sight to request a contact approach. All that is required is for the airport to be reporting at least 1sm visibility and for the pilot to remain clear of clouds.

    When would this be helpful for an IFR pilot? Good question. Here’s a scenario.

    Pilot Smalls is about 20 minutes from his destination, which is an uncontrolled airport with only one approach to runway 17. He is approaching from the south and the initial approach fix for the approach to 17 is about 15 miles north of the airport. The airport is under Center control. When he has arrived at this destination in the past, Center usually could only vector him down to 4,000 AGL. He is very familiar with this airport and the surrounding area as he comes to this destination at least 2-3 times a month for business.

    Pilot Smalls listens to the AWOS, which is reporting a 2500 foot scattered layer and 10 miles visibility. He knows it is right traffic for 17 since there is a 2,000 foot antenna on the east side of the field. There is some hilly terrain around, but all the terrain is well below pattern altitude and doesn’t cause a safety issue.

    Looking out at the clouds, Pilot Smalls observes that the cloud layer is scattered to broken, but more scattered on the west side of the airport, with several large openings that he can see the ground through. Center asks for his approach request and Pilot Smalls requests a visual approach. Center gives him a descent to 4,000 AGL, their MVA for the area. They tell him to report the airport in sight for the visual approach.

    At 4,000 AGL, Pilot Smalls is going through the scattered layer of clouds, but can see the ground in between the clouds and deems he has room to maneuver safely between the clouds and stay clear of them. He can’t see the airport, so a visual approach seems unlikely. He can’t cancel IFR because then he would have to keep the VFR cloud clearance and visibility requirements in Class E airspace (1,000 feet above, 500 below and 2sm horizontally), which isn’t possible in this case.

    5 miles from the airport, ATC states, “N12345, I’m going to have to send you out for the approach since you don’t have the airport in sight.” Pilot Smalls then requests a Contact Approach. ATC clears him for the Contact Approach to his destination, so Pilot Smalls descends through a break in the clouds, remaining clear of clouds, until he gets below the base of the ceiling. He maneuvers onto the right downwind, lands and cancels IFR.

    Contact approaches can be useful at controlled and uncontrolled airports. The first time you request one, do so with a higher ceiling and some room to maneuver to keep your safety margins. After you’ve done a few, you can determine what your personal minimums are for a Contact Approach.

    I would not recommend doing a Contact Approach at an airport you are unfamiliar with. It’s vital to know what obstacles are around since on a Contact Approach, the pilot is now responsible for traffic avoidance and terrain avoidance, whereas on a visual approach, ATC resumes that responsibility.
