Thunderstorm Avoidance

Thunderstorms are not to be taken lightly. I know you have probably heard that many times in your flying career. Weather related accidents account for approximately 25% of airline and GA accidents.

The Airman’s Information Manual suggests giving a 20 mile berth around thunderstorms. If you are an experienced aviator or a newbie please take this piece of advice seriously. At one flight school where I taught, we had the policy of maintaining a 25 mile buffer around isolated thunderstorms. A bit excessive you think? Maybe, but safety is a good thing!

On this particular day, I was operating a Bell Jet Ranger helicopter during a power line patrol. Power line patrol by itself offers numerous challenges. The job consists of flying along electric power transmission lines at approximately 40 feet above the ground at 40 knots. The crew consisted of me (the pilot) and an observer. The observer is an employee of the power company and it is his job to determine which line(s) will be patrolled during the given day. As I fly along the lines, the observer is checking for anything out of the ordinary such as broken, cracked, or even shot out insulators, excessively large bird nests at the top of structures, or woodpecker holes in wooden poles. The observer knows the lines and he is also a great help in letting me know there is a crossing, and potentially higher, line in our flight path. That makes him a true safety asset!
Power line thunderstormIt was late afternoon during the summer and we were about to finish up for the day. We only had about another 10 miles of line to follow before calling it a day. Up ahead, I noticed an isolated thunderstorm near our power line. I could see the heavy rain falling below the anvil shaped leading clouds. It appeared to be well beyond the end of our day’s work so we pressed on.

As we drew closer to the thunderstorm, we were suddenly tossed up on our left side like a dog toy in mid-flight! It seemed like we were 90 degrees to our normal cruise attitude and, to make it worse, we had the doors off on that hot summer day. I was able to recover and we did an immediate about face and high tailed it home. Forget the rest of that line, tomorrow is another day.

The destructive force of thunderstorms cannot be overstated. In addition to extremely heavy rain, they can contain strong wind shear, large hail, and severe turbulence, each of which can damage or destroy an aircraft. Take care when one of these bad boys is near your flight path. Give it plenty of respect and a lots of room, for safety’s sake.

  • Night Flying

    Ah, fall is finally here.  In Texas, it arrived about a month late, but showed up with a vengeance.  A strong cold front caused a 40 degree temperature drop in 12 hours earlier this week, bringing rain, lower freezing levels, and lots of wind.

    Fall means cooler temps, but fall also means less light.  The sun begins to set sooner, plus the fall back time change in November cause darkness to spring upon an unaware pilot.

    Before getting in to too many night landings tips, just a friendly reminder, passengers can only be carried at night if the PIC has completed 3 takeoffs and landings to a full stop in the last 90 days during the time period of 1 hour after sunset to 1 hour before sunrise.

    Lots of us have been landing long before sunset for most of the past couple of months, so those night flying skills might be a little rusty.  The best way to remedy night flying rustiness?  Call an instructor and go get some practice.

    In the meantime, here are some tips as to what to expect for your next night flying experience.

    1. Your Eyes Are Very Important.  This may seem like an obvious statement, but night vision can be affected by many things.  Before you takeoff, you want to make sure you can see in the dark.  The FAA recommends no bright lights 30 minutes prior to takeoff.  They also recommend using oxygen at night as this greatly improves night vision, even at low altitudes.  Use off center viewing to help spot traffic or other objects in the air.  Finally, when preflighting, use a red flashlight as much as possible, but if you do have to use a white light, close one eye to keep one eye from being blinded.
    2. Utilize Approach Lights on Landing.  Night landings are very different then day landings.  It is very difficult to get the proper depth perception, not too mention see obstacles below you on your final approach to a runway.  PAPI’s, VASI’s, and instrument approach glide slope’s become very important.  If you are VFR only pilot, if your airport has a PAPI or a VASI, keep 2 white and 2 red (or 1 white and 1 red) lights.  If you see 3 red (or 2 red), climb.  If you see 4 red, definitely climb.  If you are an IFR pilot, I highly recommend always flying an approach at night.  What if your airport doesn’t have a PAPI, VASI, or approach with a glide slope?  You might not want to utilize it at night.  One side note on VFR flight: Clouds are nearly invisible at night.  If you do fly into a cloud (a clue is your strobe lights start reflecting back at you), don’t panic.  If you have an autopilot, turn it on and execute a 180 degree level turn.  If you don’t have an autopilot, start scanning your instruments, keep your attitude indicator blue side up, and make a shallow 180 degree while maintaining altitude.  Then call ATC, advise them what happened, and ask for help.  One more note:  I highly recommend that if a pilot finds that he/she will fly at night at lot, get an instrument rating and fly IFR at night.  It’s much safer.
    3. Practice Landings Before Carrying Passengers.  The tendency when landing at night is to level off too high before flaring, causing the airplane to bleed off speed and energy too high above the runway.  This can lead to a stall, a hard landing, and/or too high of a pitch attitude at touch down causing a tail strike. A good tip is start your level off when you can see the tire marks on the runway.  Make sure you practice night landings, preferably with an experienced instructor who is night current and proficient, before carrying any passengers on board, even if you are night current, but haven’t landed at night in a while.
    4. Night Emergencies.  For engine failures at night, you are very limited on options.  Unless you have a Cirrus equipped with a CAPS parachute system, you really have two options if an airport isn’t within gliding distance.  Find a wide, lighted road that appears to be lightly trafficked.  A word of caution, though:  be careful of light poles, fences, concrete medians, cars, and buildings.  The LA freeway would not be a good option (though there are exceptions to this rule as is evidenced by the picture below).  The second option is find a dark spot and pray it’s a field (or the Hudson River).  As you get closer, you can turn your landing light on to see what the ground looks like.  If it looks good, keep the light on and continue.  If you don’t like what you see, turn your landing light off and continue….

    Flying at night can be the best time of day to fly.  It’s usually smoother, cooler, and you get to see all the city lights.  It is a very different environment, however, so make sure to get some training before darkness settles in on your next trip.

  • Make The Upgrade to Pressurization

    Are oxygen cannulas rubbing your nostrils raw?

    Is turbulence giving you back problems?

    Would you like to be above the bumps, breathing without tubes stuck up your nose or a mask on?  Would you like a quiet ride?

    Sounds like you need pressurization.  Need more convincing?

    What’s that you say?  You don’t have a multi-engine rating?  You don’t want to spend the money on a turbo prop?

    Have no fear, there are options galore for you to choose from in the single engine piston marketplace, both certified aircraft and experimental.

    A word of caution, though; once you go pressurized, you don’t go back….

    Here is my review of the certified, pressurized single engine piston options.

    Piper PA46 Malibu/Mirage/M350

    In 1983, Piper shocked the world with an amazing airplane.  The pressurized, Continental TSIO-520 (310 HP) powered PA46 Malibu hit the market in the fall of that year taking the piston world by storm.  A six seat, cabin class, pressurized single engine piston that easily cruised at 190-200 knots while only burning 16-17 GPH. It was awesome.  It even had an air stair door that felt like getting on a private jet.

    I love the original Continental powered Malibu, specifically the ’86-’88 models.  Piper initially had hydraulic flaps, which were clunky and had several issues (most notably, the hydraulic system would randomly kick offline while the flaps were in motion at very in-opportune moments).  Piper switched to the electric flaps in ’86, making the ’86-’88 year models very desirable.

    Unfortunately for Piper, the Continental TSIO-520 was not the engine manufacturer’s best product.  There were several Malibu crankshaft problems and engine failures, so much so that Piper decided to go with the Lycoming TIO-540 engine in 1989, creating the Malibu Mirage (all the current Malibu’s operating the -520 engine have been overhauled many times over, so there are no safety concerns with the -520 engine).  The Lycoming powered Mirage (350 HP), cruises a little bit faster than the Continental powered Malibu, but burns about 5 more GPH.  Piper still makes the Mirage, now dubbed the M350, complete with the Garmin G1000 NXi panel.

    The 4 seat, cabin class back seat is very roomy (unlike a Bonanza or Saratoga).  There is plenty of rooms for bags, both behind the back seat and in the handy nose compartment, which is wide enough to fit golf clubs, minus the driver.  The 1600 pound useful load (880 pound payload with full fuel), allows for a lot of people and gear to be loaded on board.  The airplane is a little stingy on CG, though.  You do not want to have a CG that is out of the rear limits.

    The airplane is fun to fly.  It has a heavy elevator, similar to a Bonanza, which requires a lot of trim on landing.  It’s very long wings cause it to float a bit on landing if the pilot comes in too fast.  It’s very docile in stalls and extremely comfortable for cross country flying.  The air conditioning system works very well, though it is still hot on the front seats when sitting on the ramp on a Texas July afternoon.

    Many of the airplanes have upgraded to glass panels.  Most are still equipped with the King KFC 150 autopilot, some with a Yaw Damper, some not.  The KFC 150 is a good autopilot, but when Garmin certifies their GFC 600 for the PA46, that will be a popular retrofit.

    If I had my pick, I would buy an ’86-’88 Malibu with an upgraded Continental TSIO-550 engine.  Climbs a bit better and does a bit better in cruise than the original -520 engine.  See why here.

    I would rate the PA46 line as the best pressurized single engine piston option out there.

    Cessna P210 Centurion

    The P210 was introduced by Cessna in 1978.  It also came with the Continental TSIO-520 engine that the Malibu was certified with.  Climbing at about 700-800 fpm (equal to the Malibu), the P210 cruises at around 190 KTAS as well, burning around 17-18 GPH.  Like the Malibu, the P210 had a Continental TSIO-520 power plant, but, unlike the Malibu, the P210 makes the pilot work to keep the CHTs cool.  With smaller cowl openings and a tighter cowl, cooling isn’t as good as the Malibu.

    Even though the P210 has six seats, the forward facing, Cessna style 3 rows aren’t quite as comfortable as the Malibu.  The single door on the pilot’s side makes loading and unloading a bit of a chore (especially compared to the air stair door in the Malibu).  The third row of seats isn’t extremely useful, as the ceiling is lower and the proximity of the second row of seats decreases the amount of leg room, making it uncomfortable for a full size adult.  Most operators remove the pilot’s side second row seat to add an aisle to get to the back row for people and bags.  It also has a smaller cabin then the Malibu.

    There is less baggage in the P210, with the singular baggage compartment accessed through a baggage door behind the cabin.  The Air conditioning system is also not as good as the Malibu.

    It’s hard to get the P210 out of CG and overloaded.  A useful load of 1500 pounds (with 90 gallons of fuel, it drops to only 960 pounds) allows the airplane to be loaded to the gills without being overweight.

    There are some engine upgrades out there for the P210 (the Silver Eagle conversion puts a Rolls Royce turboprop on it).  The best piston conversion is the Vitatoe Conversion that swaps the engine out for a Continental Turbo-Normalized IO-550, which is a much better engine than the -520.  You still have to monitor the CHTs, but cooling is less of an issue.  These are much higher priced on the market, though.

    Because of the size of the cabin and the true reputation the P210 has of being a maintenance hog, I would rate it below the PA46 line.

    Extra EA-400

    There are 3 pressurized, single engine piston airplanes out there today: the Piper PA46, the Cessna P210, and the Extra EA-400.  Extra is the famous German aerobatic aircraft manufacturer that created the Extra 300 and 330.  In the early 2000s, Extra tried it’s hand at the pressurized single market with the EA-400 (Extra also tried to get into the single engine turbo-prop market with the EA-500, but the project fizzled before much progress was made).  Sadly, only 27 EA-400s were built before the company ran into financial trouble.

    The concept sounds cool.  A fully composite, pressurized, liquid cooled, cabin class piston.  The engine was the Continental TSIOL-550, liquid cooled power plant.  Liquid cooling means no concern about hot CHTs while you are climbing.  The problem with the engine is that there are so few liquid cooled Continental engines out there, finding a mechanic familiar with one could be an issue.

    I have never flown an Extra 400, but there are several floating around out there.  Most have steam gauges and the STEC-55x autopilot.  The price on the only one on Controller right now is comparable to the P210N but above the Continental powered Malibu.

    If you are in the market, an Extra 400 might be fun to test fly and who knows, you might fall in love with it!

    Experimental Options

    There are a handful of experimental pressurized singles out there.  I have not flown any of them, so I can’t be a good resource on recommending them.  Here is the list, however.

    Lancair Evolution Piston

    Lancair IV-P

    Lancair ES-P

    Lancair LX7

    As far as availability on the market goes, there are 8 Malibus on Controller (1 1986 model) ranging from $315,000 and down, 24 Mirages ranging from $705,000 (equipped with the Garmin G1000) and down, 25 P210s ranging from $405,000 and down, and 2 Extra EA 400s, priced at $369,000 and down.  Check out the available Experimental Lancair options here.

  • Garmin Perspective Tips & Tricks

    The Garmin Perspective and Perspective + are awesome pieces of equipment.  There is so much a pilot can do with this system that it can sometimes get overwhelming. There are two very important features of the Garmin Perspective that all IFR pilots need to know, but are tricky to do if the correct buttons aren’t pushed.

    The two features of the Garmin Perspective I want to focus on today are the “Load Airway” feature and the “Hold at Waypoint” feature.  The “Load Airway” feature is especially handy when flying IFR long distances with several airways as part of the clearance.  Here’s how to utilize both on the Garmin Perspective.

    Load Airway

    • On your flight plan page, insert the waypoint where you will be joining the airway, or, if your clearance was radar vectors to join an airway, then insert the waypoint on the airway that begins the leg you will be joining on
    • Press the Menu key on the keypad
    • A menu will pop up. Scroll down to highlight Load Airway
    • Highlight the Airway you want from the next menu that pops up then press Enter
    • Then, a list of waypoints will display to exit the airway. Highlight the waypoint where you will be exiting the airway and Press Enter
    • The cursor will then move down to Load at the bottom of the menu. Press Enter to load the airway
    • The Airway and all the waypoints in between your entry and exit waypoints appear in your flight plan
    • If you are getting vectors to join the airway, you’ll need to use the Activate Leg function to activate the leg you will be joining the airway on
      • On the Flight Plan page, highlight the waypoint that ends the leg you want to activate
      • Look for the ACT LEG soft key on the lower right hand side of the MFD and press
      • This Activates the leg on the airway. Then, just simply fly the heading assigned by ATC until the CDI needle centers showing you are on the airway

    Hold At Waypoint

    The Garmin Perspective allows pilots to place a holding pattern at any waypoint that is in the Nav Database (or any user created waypoint).  Here’s how to do it.

    • On the Flight Plan page, highlight the Waypoint that you want to hold over and press Menu on the keypad
    • On the menu that pops up, highlight Hold At Waypoint and press Enter
    • On the next menu that pops up, input either the inbound or outbound course, right or left turns, leg time or distance, and the EFC time, then highlight Load and press Enter
    • You will see the hold now as a Waypoint in your flight plan
  • Synthetic Vision Technology

    Let’s say you’re flying in the mountains of Colorado on a cloudy day.  There’s a solid layer from the surface all the way up to 14,000 feet.  You’re inbound to Eagle (KEGE) on the RNAV (GPS) D approach.  There are mountains next to you and below you, but you aren’t concerned since you can see them all.  The base of the last reported overcast layer was 3,000 feet, so you know you’ll break out before the MDA and land no problem.

    At 11,100 over AWACC, you clearly see the top of the mountain below you.  You are comfortably above it. You already have the runway in sight as well.  You pop out of the clouds on the approach at 9,700 feet, spot the airport and follow the tower’s instructions to circle north of the runway for a left base for runway 7.

    How could you see the mountains inside the clouds?  You have Synthetic Vision installed on your glass panel, that’s how.

    Aspen Synthetic Vision
    Aspen Synthetic Vision

    Synthetic Vision, which has actually been around since the ’70s when NASA and the US Military first developed it, was first FAA certified for the Gulfstream PlaneView flight deck in 2009.  Garmin, Avidyne, and Aspen are the main general aviation manufacturers of synthetic vision these days.  All Garmin PFDs are now equipped with Synthetic Vision while Aspen gives you the option to upgrade to Synthetic Vision when you get one of their PFDs installed.  Avidyne gives you Synthetic Vision in their R9 upgrade for the Cirrus.

    What is Synthetic Vision?  Basically, it’s a 3-D picture on the primary flight display showing terrain, obstacles, traffic, and runways.  It greatly enhances situation awareness in areas of terrain or high obstacles during IFR conditions or at night.

    The goal behind the development of Synthetic Vision was to decrease the amount of controlled flight into terrain (CFIT) accidents.  A CFIT accident consists of a perfectly airworthy airplane flown by a pilot (or autopilot) unintentionally into terrain. These accidents can happen in low visibility conditions or at night, but the reason is mainly due to the pilot losing track of his position in relation to obstacles or terrain (or water as was the case with JFK Jr.).

    With Synthetic Vision, the goal is to enhance pilot knowledge of what is around the airplane at all times. When you’re at altitude, the terrain below you looks flat.  When you start descending down amongst the rocks, the hills or mountains start to rise up on your screen.  For those used to the coloration with the 2-D terrain feature on a GPS unit, it translates very easily to the terrain coloration on a Synthetic Vision equipped PFD. Terrain that is between 100 and 500 feet below the aircraft is shown as yellow, while terrain closer than 100 feet is depicted as red.

    Garmin Synthetic Vision
    Garmin Synthetic Vision

     

    One neat feature on Garmin units is the Highway in the Sky.  When a pilot puts a course or a flight plan in the GPS, the PFD displays magenta boxes at the altitude selected displaying the route.  It’s handy when hand flying to just “fly through the boxes.”  They also display descent angles on approaches.

    Synthetic Vision is still optional on Garmin and Aspen units, but I highly recommend springing for it.  It will give you a higher level of safety and keep you out of the rocks.

  • Iridium Zoleo Allows In Flight Messaging

    Satellite communications company Iridium now has a really nifty little product called the Iridium Zoleo Satellite Communicator. Most pilots who fly newer Cirrus Aircraft will be familiar with the company name Iridium. Iridium manufactures the built in satellite phone that is an option in all Cirrus after 2012. The Iridium Zoleo brings messaging capability to any airplane in a cost effective and simple manner.

    The Iridium Zoleo is a device roughly the size of a walkie-talkie. It links up with the Iridium satellite network to send and receive messages and emails anywhere in the world (or air!). To make things easier, the Iridium Zoleo links with a phone via Bluetooth to a free app that allows the user to write a message directly from the phone and send through the device.

    The Iridium Zoleo is affordable at only $200. A plan has to be purchased in order to send messages, with 3 different levels of subscription offered: 25 messages a month for $20, 250 messages a month for $35, or unlimited messages per month for $50. Each plan offers a $6 upgrade to allow unlimited worldwide breadcrumbs and tracking.

    The Iridium Zoleo has a 200 hour battery life and is designed to be shock, dust, and water resistant. Plus, the device has a built in SOS that can be used anywhere in the world. So, you can take it rafting down the Grand Canyon, hiking in the Andes, flying over the Atlantic, or SOS if you are stranded in the middle of the Indian Ocean.

  • Flight Training Deemed Essential Business

    There have been lots of changes in all parts of our lives with the coming of COVID-19. All of our lives have been affected in one way or another. We hope and pray that none of your families have been directly affected by the illness.

    A lot of us have been living under Shelter in Place orders for several weeks now, only going out for groceries and making sure to keep our distance from people. We have to take a different mindset when we go out now. Even meeting new people is different since we can’t shake hands.

    Flying has been an afterthought for a lot of pilots. There have been multiple ATC facilities where controllers have been afflicted with the virus and have had to shut down for hours or days. Airspace can change pretty quickly, going from what we all know as normal, to an ATC-ZERO scenario. This was the case for New York Center several times over the last two weeks.

    There was some uncertainty regarding flight training under the shelter in place orders and Texas Top Aviation has been asked several questions about it over the last week. Yesterday, the Flight School Association of North America (FSANA) announced that flight instruction was indeed an essential business.

    In an article on GeneralAviationNews.com, the website quoted a memorandum of understanding written by attorney George Winton on March 24th. Winton was a senior attorney for the FAA and U.S. Department of Justice, and now operates The Aviation Law Firm in Annapolis, Maryland.

    “This memorandum affirms the statement that…flight training would be included as a critical infrastructure activity. Those engaged in the provision of and receipt of flight training who work to provide enhanced compliance with CDC recommendations for limiting potential COVID-19 exposure and spread would be considered exempt from travel limitations imposed by local authorities.”

    Winton’s memo was sent to the Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency (CISA). In the memo, Winton stated:

    “CISA listed Other Community-Based Government Operations And Essential Functions as follows: Workers who support necessary credentialing, vetting and licensing operations for transportation workers.”

    “The aviation sub-sector stakeholders involved with operation of recreational aircraft and flight schools, who employ Essential Critical Infrastructure Workers from the Transportation Sector, support necessary credentialing, vetting and licensing operations for transportation workers seeking pilot certification by the Federal Aviation Administration. Since CISA intended to be overly inclusive to reflect the diversity of industries, the aviation mode stakeholders understand that essential employees involved with the operation of recreational aircraft and flight schools continue to be identified as Essential Critical Infrastructure Workers from the Transportation Sector. Accordingly, the aviation sub-sector stakeholders who employ Essential Critical Infrastructure Workers from the Transportation Sector will continue to operate recreational aircraft and flight schools, appropriately modified to account for CDC workforce and customer protection guidance, based upon the CISA memorandum dated March 19, 2020.”

    Based on the above guidance, Texas Top Aviation will continue to operate flight training in all of it’s normal capacities, while maintaining vigilance concerning sanitation, cleanliness, and health. Our company will keep it’s customer’s up to date on instructor health and wellness and won’t hesitate to cancel if there is any kind of health concern. We ask our customers to do the same.

    If you are scheduled to train with Texas Top Aviation, please don’t hesitate to contact us with any questions or concerns you might have.

    To read the entire memo from George Winton, you can find it here.


    Concerning the 2020 Texas Top Aviation Santa Fe Golf Fly In scheduled for June 5th-7th, that event is currently being re-scheduled for September 2020. Dates will be announced by the end of April. We look forward to seeing you in Santa Fe in September!
