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.

  • IM SAFE: Are You Really?

    As pilots, we are all familiar with the IM SAFE acronym that the FAA puts out.  It comes up as part of the ground training over Human Factors during private pilot ground school.  We all memorize it, spit it out for our check rides, then most of us promptly forget about it.

    When I was training for my pilot’s licenses, I was at a Part 141 school that was very standardized (LeTourneau University, who has a fabulous aviation school).  Before each flight, we had to do a self evaluation based on the weather and the IM SAFE checklist.  Based on our answers, we would then determine if the conditions were conducive to flying as well as if I was physically okay to fly.

    This was a great tool because not only do pilots have to pre-flight the airplane, they also need to pre-flight themselves.  It’s very easy to fall into one of the “Hazardous Attitudes” if there is a pressing meeting or you haven’t flown in a while and it’s a beautiful day, but maybe you aren’t physically fit to control an airplane.

    Let’s break down the IM SAFE checklist to dig a little deeper into the physically fit side of flying.

    Illness

    This one is pretty easy.  Are you sick?  If so, how sick?  If you can’t hardly talk or your body feels like it was hit by a truck, then flying probably isn’t in your best interest.

    The tricky area can become if you are only a little sick.  Maybe you have a cough or a little cold or a headache is starting to form.  You probably could go fly, but is it really a good idea?  It could be something worse, or it may be nothing.  You have to know yourself and put limits on yourself before you wake up on the day of your big meeting two states over.  Set illness personal minimums and stick to them.

    Medication

    There are a slew of drugs, both prescription and over the counter, that pilots cannot take and fly.  AOPA has a hotline to call for pilots to find out if they can fly with the medication they are taking, or what meds they can take to give them relief and still operate an aircraft.

    Another great resource is your medical examiner.  Just give him/her a call and they will be more than happy to let you know what you can and can’t take.  They’ve been educated in the area of aviation so they are very knowledgeable.

    Stress

    StressometerThis is a huge one that pilots ignore a lot.  Maybe it was a stressful day at work, maybe you are running late to the airport, your meeting got moved up, whatever.  Stress can jump on you and mess up a pilot’s thinking very quickly.  If you have a lot of other things on your mind and you aren’t able to focus just on flying, it might be a good idea to stay on the ground.

     

    Alcohol

    Out of the whole IM SAFE list, the alcohol limitations are very clearly defined.  8 hours bottle to throttle, no more than 0.04% BAC, no operating an airplane while under the influence, and no carrying passengers who are visibly intoxicated.  For your personal minimums, it’s a good idea to increase that time to 12, 18 or even 24 hours bottle to throttle.

    Fatigue

    Learning to fly while a college student led to a fair share of canceled flights due to fatigue.  I operate best on 8 hours of sleep in the past 24 hours.  I can function on 6, but anything less than 6 hours, my performance drastically drops off, sometimes to a point where I wouldn’t be safe.  I discovered this while with my flight instructor attempting to do a holding pattern and completely botching it up.

    I observed this as a CFI quite often.  If I was doing ground with a student and they were struggling, my first question would be, how much sleep did you get last night?  More often than not, if I had to ask that question, I would get an average answer of 3 to 4 hours (I even had one guy show up for a flight block on 2 hours sleep.  I sent him back to the dorm).

    Fatigue is very easily overlooked because it’s not measurable.  Needing to get a flight lesson done or needing to get somewhere when you are obviously fatigued is not a good idea.  Make sure you get a good night’s sleep before a flight and don’t be afraid to cancel if you didn’t.  Set some sleep personal minimums and make them hard and fast.

    Eating

    Don’t skip meals and fly.  Performance greatly decreases when a pilot is hungry.  At the very least, stick a couple of food bars in your flight bag to give you some nourishment.

    Also, stay hydrated, especially in the summer time.  I carry a huge bottle of water with me on all my flights because I get headaches if I don’t drink enough.  Getting dehydrated on a long flight can lead to all sorts of performance problems (over hydration is also a problem in the air, but that’s what Gatorade bottles are for, right?).

    All this to say, have some personal minimums when it comes to you and your body.  Check the plane, check the weather and check yourself.  If anything falls in the “red” area in any one of those three categories, stay on the ground and don’t press your luck.

  • TBM Debuts the 960 at Sun N Fun

    This is a Press Release from Daher’s website, the maker of the TBM 960.

    Sun ‘n Fun Aerospace Expo, Lakeland, Florida, April 5, 2022 – Daher today unveiled the latest high-end version of its TBM pressurized single turboprop aircraft family – the TBM 960 – which incorporates Pratt & Whitney Canada’s advanced PT6E-66XT engine and a fully digital e-throttle, along with a digitally-controlled cabin that incorporates an all-new environmental control system, LED ambience lighting and electrically-dimmable windows.

    The TBM 960 was introduced at the Sun ‘n Fun Aerospace Expo in Lakeland, Florida, where Daher is exhibiting the first production airplane (exhibit stand #MD-22B).

    “The TBM 960 is the quintessential TBM, representing the fifth evolution of our very fast turboprop aircraft family since the TBM 900-series’ introduction in 2014,” commented Nicolas Chabbert, the Senior Vice President of Daher’s Aircraft Division. “It takes the maximum advantage of today’s turboprop technology to provide digital control of the engine and the propeller.”

    The TBM 960 retains the rapid speed of Daher’s TBM family while enabling lower fuel consumption. At Daher’s recommended cruise setting of 308 kts., the fuel consumption is only 57 U.S. gallons per hour, which is a 10% fuel economy compared to maximum cruise setting for more sustainability.

    At the heart of this latest TBM version is the intelligent PT6E-66XT powerplant and Hartzell Propeller’s five-blade RaptorTM composite propeller, both of which are linked to the dual-channel digital Engine and Propeller Electronic Control System (EPECS).

    With the EPECS, the PT6E-66XT’s startup is fully automated after a single-switch activation. The cockpit’s power lever is an e-throttle, using a single forward position from takeoff to landing – with the EPECS optimizing powerplant performance throughout the flight envelope while

    reducing pilot workload by integrating all functions and protecting the engine’s life. Analysis of engine parameters is driven by 100-plus smart data inputs.

    The RaptorTM propeller is fully integrated into the propulsion system. It is specifically designed to reduce overall weight and improve the TBM 960’s takeoff distance, climb and cruise speed. Turning at 1,925 rpm during maximum power output, the Raptor contributes to limiting noise and vibration. Its sound level during takeoff is just 76.4 decibels, meeting the most stringent international noise standards.

    With its G3000® integrated flight deck, the TBM 960 retains Daher’s e-copilot® concentration of technological innovation and safety systems in the TBM, which can be compared to an “electronic copilot.” This includes an icing protection system, flight envelope monitoring through the Electronic Stability and Protection (ESP) and the Under-speed Protection (USP) systems, the Emergency Descent Mode (EDM) function, as well as the game-changing HomeSafeTM emergency autoland system.

    New to the TBM 960 is the Garmin GWXTM 8000 doppler weather radar with advanced surveillance features such as lightning and hail prediction, turbulence detection, zero blind range for close-in returns, and ground clutter suppression. The TBM 960 also is the first application of Garmin’s GDL® 60 next-generation data transmitter for automatic database upload and interconnection with mobile devices.

    The TBM 960’s Prestige cabin extends Daher’s use of digital power inside the aircraft, featuring an all-new environmental control system, LED ambience strip lighting integrated into both sides of the overhead ceiling panel, and electronically-dimmable windows – all controlled by a PassengerComfortDisplay(PCD). Enhancementsinthecabin’sstyleandcomfortalsoinclude new ergonomically enhanced seats, USB-A and USB-C power plugs, individual cupholders and headset hangers for each occupant.

    For the TBM 960, a fifth TBM paint scheme – called Sirocco, based on the creativity of French designer Alexandre Echasseriau – has been added to the aircraft’s style customization possibilities.

    The TBM 960 has been certified by EASA (the European Union Aviation Safety Agency); with certification by the U.S. FAA (Federal Aviation Administration) currently underway. Deliveries will begin in the first half of 2022.

    With the new aircraft’s launch, Daher’s TBM family is now offered in two versions: the TBM 960 and TBM 910.

  • Oh, Deer (Part 3)

    Read Part 1 & Part 2

    Throughout the whole event, I learned quite a few things both about flying and about myself. Here are some of the lessons which I have taken away from the accident:

    1. No flight is routine: When I took off that morning I was about as relaxed as I could have been while going to fly. I was flying an airplane that I knew well, in beautiful weather, to familiar airports and even carrying passengers which I had taken on this exact trip more than a dozen times. The accident brought into startling clarity that anything can happen at any time. I had done everything right that morning (preflight, weather briefing, planning, etc) , and none of that did anything to stop the deer from jumping out onto the runway. All we can do is ensure the items we do have control over are covered and try to be prepared to deal with anything else that arises. This ties directly into my next point:
    2. Making sure everything is correct: When you do go fly, make sure that you have all your paperwork and personal details taken care of. I can think of a few times over the course of my flying career where something wasn’t quite right with the paperwork, or perhaps I had forgotten my wallet and I was tempted to go fly anyway. “It’s 8pm on Sunday, I’m not going to get ramp checked.” Well, I can assure you that the paperwork and questionnaires which were required to be submitted to the FAA, NTSB, and Insurance companies would have uncovered any discrepancies in my logbooks, currency, or legality. It isn’t worth the risk of flying without having everything in place just in case something happens. It isn’t just a random ramp check which can get a pilot into trouble.
    3. Ask for help: The story of my collision with a deer would have had a very different outcome if it weren’t for the help that I received from countless the people on the ground. If you’re ever in a situation where you could use a hand, don’t be afraid to ask for help. If I had simply turned around and landed back at Wings, I wouldn’t even have had any idea that my landing gear was missing! The people in the control tower, the maintenance guys, the approach controllers in Philly, the emergency responders, and many more people all played their part in orchestrating a successful outcome.

    4. Dealing with the Paperwork: I have had dealings with the FAA before, but never for an accident. I was afraid that the investigation would be a witch hunt and I would have to defend myself while someone poured over all my planning and paperwork looking for potential errors. But, my fears were totally unfounded. Although I did have to answer many phone calls, write many reports, and fill out much paperwork, the FAA, NTSB, and Insurance companies were very patient in waiting for my responses and even complimentary in how the situation played out. I really enjoyed working with all of them and appreciated their encouragement and help.
    5. Emotional Response: After the dust had settled and the smoke had cleared, I was left standing on the side of the runway with the passengers and my boss. I offered to fly them back to Philadelphia or continue to Pittsburgh and assured our Chief Pilot that I was feeling fine and ready to fly again. Fortunately, there wasn’t a need. Over the next week or two, I noticed a change in myself. I wasn’t fine. I have never had headaches, but shortly after I landed I developed a headache that didn’t go away for days. I had trouble focusing on anything and I had trouble finding motivation to do much but sit and stare at a wall. I wasn’t sharp and I caught myself making silly mistakes in my normally routine activities. I wasn’t depressed, or sad, it was just an unwanted mental and physiological response to the stress and shock of what happened that morning in the Baron. I didn’t feel like myself for quite some time and I even found myself a little on edge whenever I lined up for takeoff on subsequent charters for while afterward. Eventually I started to feel normal again, but it was a slow process.
    6. Feather the Props: I can’t tell you what a difference it makes when those props go from wind milling to feathered. It became clear to me that feathering a prop could make a huge difference in deciding the outcome of an emergency situation.
    7. Good training and checklists usage: This one is pretty straight forward, but it’s worth mentioning. Good training and proficiency make all the difference when the odds are against you. Make sure that you use all your resources when your back is against the wall, and that includes the checklists. Under the stress of the flight I had forgotten to close the cowl flaps and would likely have landed with them open without the aid of the Emergency Procedures Checklist. This would have resulted in unnecessary damage to the airframe.
    8. No need to rush: There is no denying that I had things stacked in my favor that day. I had nice weather, extra gas, daylight hours, and even the luxury of landing at my home airport. But, regardless of all those variables, there is no need to rush into anything. Ask questions, find answers and come up with a plan. Obviously not all emergencies present the pilot with the luxury of time, but use all time and resources you have to your advantage.
    9. Polish up those procedures: The deer accident really made me want to go out and brush up on all the emergency procedures which I hadn’t performed since my last checkride. The realization that I could need any of them at any time was really hit home after I hit that deer. Additionally, make sure you know who to call if something ever does happen.
    10. Know the systems: Familiarity with the systems on the airplane makes it easier to troubleshoot and solve issues on the fly and makes it easier to spot a problem in the first place. Knowing how systems work and what their normal indications should be helps make decisions regarding when to divert and where to land easier.

    The irony isn’t lost on me that the last article that I wrote for this newsletter dealt with how to avoid making gear up landings and the high cost required to repair one. I never would have imagined when I wrote that article last fall that I would be writing one only a few months later detailing my own gear up landing.

    The bottom line is that there is nothing a person can do to prepare for every situation which might arise throughout the course of a flight, and it’s also impossible to know which emergency you may have to deal with if a situation arises. All we can do is stack odds in our favor by making sure that we address the things within our control such as aircraft maintenance, careful flight planning, checking weather, and having personal minimums set in place to keep us from flying outside of our skill sets and comfort zones.

    Additionally, ensuring that you are knowledgeable and proficient in your aircraft’s procedures will give you the best chance for success. When things start going wrong, keep calm, and ask for help. Work the problem instead of guessing or rushing into a less than desirable solution. No one wants to be caught in an emergency like a deer in a landing light!

  • Epic E1000 Gets the GFC 700

    When the Epic E1000 was finally certified in the spring of 2020, there was much celebrating across the aviation world. Epic Aircraft expended a lot of time and energy getting the E1000 certified and into production (more information on that journey here and in Flying Magazine here).

    The airplane is amazing. In the single engine, 6 seat turboprop market, it easily blows away the competition. With it’s 1,200 SHP PT6-67A, it has double the horsepower of the M600 (600 SHP), and 350 more horsepower than the TBM 940 (850 SHP). It’s 60 KTAS faster than the M600 and, even though the TBM can keep up (both airplanes have equal top cruise speeds of 330 KTAS), the Epic E1000 can carry a payload of 1,024 pounds with full fuel, while the 940 can only carry 584 pounds with full fuel. The TBM carries about 15 minutes more of fuel, but to me, that’s pretty negligible.

    Did I mention climb rates? The E1000 climbs at an average of 1500 FPM at Vy (it’s capable of 4,000 FPM), making it to 25,000 feet in 10 minutes. The TBM climbs at 1000 FPM, taking 13 minutes to climb to the same altitude, while the M600 settles in at about 800 FPM, reaching FL250 in 21 minutes.

    If you expand the comparison to include the Pilatus PC-12, the two airplanes have 1,200 SHP, but the Epic is 50 KTAS faster and they both have about the same weight carrying ability.

    In the most important arena, price, the E1000 is around a million dollars cheaper than the TBM 940.

    The one drawback to the Epic E1000 that immediately was noticeable was the autopilot. Epic originally installed the STEC 2100 autopilot to pair with the G1000 (and later the G1000 NXi). Epic decided to stick with the STEC 2100 through certification for the plane since that autopilot was on all of the E1000s paperwork going through all the levels of FAA approval. To change to the GFC 700 during the certification process would have been a massive undertaking that probably would have delayed certification.

    The STEC 2100 is a good autopilot, but, as any G1000 pilot can tell you, the lack of integration between any STEC autopilot and Garmin panel leaves some to be desired. Not all the bugs talk, which often requires dual data entry, which can lead to forgetting to do both the bug and the autopilot when things get busy. Hello, altitude deviation.

    The goal for Epic was never to leave the STEC autopilot in the airplane. The first E1000s were rolled off the line with the STEC, but Epic didn’t take long to change the autopilot to the much more integrated Garmin GFC 700. That took place this winter (2020), and the E1000 received it’s first upgrade, with Epic dubbing the airplane the Epic E1000 GX.

    I expect the innovators in Bend, OR, where Epic is based and where tons of innovation in aviation happens (Lancair/Columbia started in Bend while RDD is based there as well), to quickly come out with more avionics upgrades for the airplane. I wouldn’t be surprised to see a G3000 version at some point, complete with auto throttles and the new Garmin Autoland. Epic would be smart to follow in the steps of Daher and offer two models, one with the G1000 and one with the G3000 (the TBM 910 has the G1000 NXi while the TBM 940 has the G3000).

    I have yet to fly in an Epic E1000, but I would certainly jump at the chance to do so. Someone asked me yesterday what airplane I would buy if I had a blank check. With the GFC 700 now in the Epic, it would absolutely be the E1000 GX.

  • Flying the Hudson River Corridor

    Ever since I moved out to the Philadelphia area, the Hudson River corridor in New York City has become one my favorite places to fly. It’s hard to overstate the beauty of the city from low over the river. Every time I have a family member or friend come to visit, I try and take them over to see the city from the air.

    Each time I fly up the river I can’t believe that we are actually allowed to do so, flying below the tops of the buildings and close enough that you feel that you could reach and out touch them. The draw back to the Hudson River Corridor is that it can be busy, intimidating, and confusing. However, with some reading and preparation, the Skyline flight is easy to do and extremely rewarding.

    Having the right weather is an important first step. The second step is try to arrive during ideal lighting conditions. If possible, select a smooth, calm day to make it easier to maintain a track down the correct side of the river. I always try and target arrival at the city around sunset. The view is spectacular any time of day, but having the lights from the city while the sun is just setting gives the best viewing. I’ve also flown over and done the whole flight after dark, which is always spectacular.

    View of the World Trade Center

    The first method of flying the river is to utilize VFR flight following. If the controllers aren’t too busy, they will provide advisories to aircraft that request the Skyline. The nice thing about doing it this way is that the controller will clear you into the NY bravo airspace and keep you above the traffic flying the Skyline in the VFR corridor below. This is the method that I have always preferred as I enjoy the added benefit of the traffic advisories and it’s nice not to worry about position reporting on the radio.

    If you want to get flight following, head toward the corridor and request the Skyline route with NY Approach. (Remember to stay clear of the Bravo until you’re cleared in!) Once you’re cleared into the Bravo and approaching the corridor, they will hand you off to Newark/ LaGuardia Tower for traffic advisories over the river. I like to approach from the south and ask for a 180 over the George Washington Bridge. This allows me to fly past the city a second time before exiting the corridor over the VZ (Verrazano Bridge) and heading back toward home.

    In red is the path I typically fly. I descend to 1400’ and fly toward the APPLE intersection picking up the shoreline around Staten Island and hugging it until crossing the middle of the VZ. Newark normally clears me into the Bravo at 1400’ or 1500’ to fly up the corridor.

    Pros:

    • Better traffic Awareness
    • No position reports

    Cons:

    • Flying slightly higher reduces the view
    • If the controllers are busy, they may deny your request for advisories  
    • Can be intimidating to talk to NY Approach/ Newark/ LaGuardia 

    The other option is to fly in the VFR corridor. If you want to do it via this method there are just a few things you need to make sure you’re familiar with before you go. When in the VFR corridor you’ll need to make required position reports on a CTAF frequency. Make sure that you have the proper charts and have studied pictures of the landmarks so that you know what you’re looking for. I tend to plan on this as a backup in the event that the controllers won’t give me advisories.

    Pros:

    • Doesn’t require talking to controllers/ class B clearance
    • More freedom to select altitude and routing as desired

    Cons: 

    • Less traffic awareness
    • Required position reporting

    All the requirements and guidelines for flying the corridor can be found on the back of the NYC TAC chart. Any pilot flying the river is required to have one of these or a NYC helicopter route chart on board. If you’re using Foreflight, look in the Documents section under FAA Fly Charts and select the NYC TAC chart in order to read the back of page.

    Below you’ll find examples of the diagrams/ instructions printed on the back of the NYC TAC charts.

    You can see the traffic flow requires northbound airplanes to hug the east side of the river, while the southbound traffic stays on the west side. The VFR reporting positions (listed from North to South) are: Alpine Tower, George Washington Bridge, Intrepid aircraft carrier, Goldman Sachs (clock), Statue of Liberty, VZ (Verrazano Bridge). Each position report should include aircraft type, position, direction, and altitude.

    Other things to be aware of:
    NYC is always a hotspot for TFR’s. There are often TFR’s for baseball games or presidential movements so make sure to check before you head that way. Additionally, there is a speed restriction in place of 140 kts, though I’m not sure why anyone sightseeing would want to go that fast anyhow.

    I realize that all of the procedures and restrictions can be overwhelming, but with the proper preparation, the Hudson Skyline is one of the most incredible places in the world to operate an airplane. There are a lot of things that are easy to get excited about that don’t live up to expectation, but this isn’t one of them. I’ve never taken anyone to the river that wasn’t impressed by what they saw and that’s why I plan to keep going back.

    About to cross the VZ looking north toward the city
