Pitch + Power = Performance

0 Comments

My first chief flight instructor had an addage he would impart to his flight instructors when we began working at that flight school. “Pitch + Power = Performance” he would tell us. Then he’d glare at us and follow up with, “nobody teaches that right, so make sure your students know it.”

Now, having been a CFI for seven years, I would tend to agree with him. I have moved on from doing mostly primary training to transition training. Transition training is taking someone who is already a pilot and teaching them how to fly a different type of airplane. In jets, you get a type rating. In piston engine airplanes, there is no FAA requirement to go through any type of extra training as long as you are rated in category and class (eg. single engine piston). But, insurance companies know that Mr. Fresh Private Pilot can’t just hop from a Cessna 172 into a Cirrus SR22 or a Bonanza, so they require transition training before insuring those pilots.

What did my chief instructor mean when he imparted his wisdom? He was speaking about a particular phase of flight, the final approach phase, regardless of whether it’s a VFR approach or an IFR approach. The pitch of the airplane and the power setting of the airplane have to be utilized together to achieve the proper speed and descent rate (performance).

VFR

On the final approach leg of a VFR pattern, most piston engine aircraft are configured with landing gear down and flaps down in the landing position. This puts the airplane on the back side of the power curve in the region of reverse command. In the region of positive command, in cruise, for example, the more power you add, the faster you are going to go and, if you pitch up, you will go up and you pitch down, you will go down. But, they work together (if you point the nose down, you will accelerate unless you reduce the power); remember, Pitch + Power = Performance.

In the region of reverse command, the pitch controls the airspeed and the power controls your rate of descent, but, again, they work together. Let’s say the airplane is 5 knots above it’s approach speed on final. Initially, the pilot will need to pitch up slightly to bleed off that airspeed. The airplane will want to climb, so as he is pitching up, he’ll need to make a slight power reduction to stay on glide slope.

Alternatively, let’s say the airplane is high, but is on speed. The pilot will make a power reduction to descend to the glide path, but he’ll also need to pitch down to maintain the proper airspeed.

What you don’t want to do is this: if the airplane is high on final, don’t push the nose down to try and get down. This does cause the airplane to lose altitude quickly, but the airspeed increases quickly. With a higher airspeed, the airplane has a lot more energy to dissipate when it gets to the runway, meaning you’ll float longer which can lead to forcing the airplane down or using up too much runway and not being able to get the airplane stopped in time.

IFR

On an instrument approach, you are on the front side of the power curve. When trying to stay on glide slope, the power is controlling the speed of the airplane and the pitch is keeping the airplane on glide slope. This can be a little bit confusing for VFR pilots transitioning to instrument approaches as they are not used to being on the front side of the power curve.

Keeping in mind that Pitch + Power = Performance, let’s put the airplane above the glide slope on an ILS approach. In order to get down to the glide slope, the pitch needs to be lowered as much as needed (it’s always better to pick a pitch attitude to fly and see if it is working to bring the glide slope back to center. If it doesn’t work, pick a new one. Don’t just push the nose down until the glide slope moves) and the power needs to be reduced to maintain airspeed (again, pick a specific power setting). Once the glide slope centers, then the pitch will be raised slightly and the power will need to be increased to hold glide slope and speed respectively.

Preventing Gear Up Landings

On the evening of November 3rd, 2015, I was returning to my home airport of Lancaster from Pittsburgh in my company’s Aerostar, after being out on charter all day. It was dark out as I entered the traffic pattern at Lancaster. After an uneventful approach, I was cleared to land behind a Mooney. The spacing looked good as I turned final, but, as I was nearing the threshold, I started to become concerned that the Mooney wouldn’t be clear of the runway in time for me to land. At that moment, over the radio I heard an uncomfortable transmission from the Mooney pilot: “Tower, Mooney ABC has landed gear up.”

It took the tower controller a minute to grasp what was going on, and I was on about a 1-2 mile final when I was instructed to go around. Thankfully, the Mooney came to a stop in such a position that I was able to use the other intersecting runway, and was on the ground only a few minutes later. I can assure you, however, that I’ve never checked my “3 green” so many times in one traffic pattern as after that incident. Thankfully, no one was hurt, but there sure was an impressive amount of emergency equipment on the runway as I taxied back to my hangar.

In aviation, there’s a saying that goes: “There are two types of pilots. Those who have landed with their gear up, and those that will.” I don’t like that saying. The potential of a gear up landing (as a result of pilot error) is something that has always been a risk that I have worked hard to avoid. Not only is a gear up landing embarrassing; but it’s also an extremely expensive black mark on any pilot’s career.

According to a July 2006, article in Aviation Consumer, the estimated cost of repairs following a gear up landing for an A-36 Bonanza would be about $27,000 and about 3 weeks of down time. 25 years ago, even my beloved E33 Bonanza was the victim of a gear up landing. While it was neither me nor my dad flying our airplane that day, the event stays in its history and reduces its value should the time ever come to sell it.

That incident in 1990 resulted in approximately $25,000-30,000 in repairs. The cause of the incident was classic: the pilot put the gear down at the normal time, but then had his downwind extended by tower. He brought the gear back up to fly the longer downwind, but forgot to put it back down later when he was cleared to land. Like many pilots, he had a set routine time when he normally put the gear down, and when his routine was changed, he didn’t remember to lower the gear once more.

Unfortunately, no matter what experience level one may be at, no pilot is immune to the possibility of such a mistake. The following are 5 tips that I have learned in my time flying that have helped myself and others minimize the chance of a gear-up landing occurring:

  1. Know your aircraft systems: What are the operating perimeters on your airplane’s gear warning system? Most airplanes have a designated speed or power setting at which the gear warning horn will sound in the event that the gear isn’t down and locked. In the Aerostar that I was flying, the gear horn was supposed to come on at 15” of manifold pressure with the gear up, but in practice, it didn’t come on until much lower than that. It has since been adjusted, but at the time it was important for me to know that if I had left the gear up, the horn wouldn’t have sounded in a timely enough manner for me to go around, much less lower it prior to touchdown. Most likely it would have just added to the noise of metal on concrete as I pulled the power all the way back in the landing flare.
  2. Don’t override gear-up warning systems: They were put there for a reason! Even if you’re out doing maneuvers and the horn is blasting in your ear for half an hour, resist the temptation to simply pull the circuit breaker or push the warning silencer to make it shut up. If a pilot disables the gear-up warning horn and then later forgets to put the gear down on landing, he or she will have a much worse headache on their hands than the one that the horn would have given them.
  3. Use your checklists and memory items: It doesn’t matter how much a pilot knows about his or her airplane, or the procedures for it. Distractions happen. Mistakes Happen. Always consult the checklist for confirmation that you’ve accomplished all the essential tasks before landing. Additionally, if you haven’t already, work on developing call outs which you perform out loud regardless of whether you are alone in the airplane or not. Whenever I’m landing an airplane, I start with my flows, go through my GUMPS (Gas-Under carriage- mixture- props- seat belt) checks, then do the printed checklist, and finally when on short final I call out “short final, cleared to land, three green.” I’ve had several passengers tease me about doing the “three green” call out while I was flying aircraft that didn’t have retractable landing gear. But, I’d much rather be in the habit of checking every time regardless of what I’m flying than forgetting to check when it is necessary.
  4. Use your available resources and develop healthy habits: If I have someone riding with me, I generally ask them to confirm that there are 3 green lights glowing on the instrument panel. Even if that person isn’t a pilot, they will probably enjoy the opportunity to be involved, and it’s a good way for me to stay in the habit of checking the gear lights to ensure that everything is properly down and locked. I’ve also found that intentionally leaving your hand on the gear lever until you have gear safe lights is a good idea. Forcing yourself to keep your hand on the handle until you have the all important lights obligates you to actually observe the indications instead of simply throwing the lever and moving onto something else. This way, if you only get an indication of 2 greens you’ll be aware of it right away and have more time to respond appropriately. It also helps you to learn the normal length of time it takes for the gear to extend or retract, which will be helpful to you to be aware of any abnormalities in the gear system.
  5. Upgrade your aircraft’s gear-up warnings: There’s a variety of ways you can improve your aircraft’s ability to warn you of a potential gear-up landing. For student pilots or pilots new to complex aircraft, it could be something as simple as a red post-it note on the panel to remind you to verify the gear position prior to landing. Or, if you own an aircraft that doesn’t have an effective way to warn the pilot of a gear-up landing, consider investing in an aftermarket gear-up warning system – surely the extra price of such an upgrade is a small amount next to the cost of repairing the damage from a gear-up landing!

Always remember, regardless of experience, no pilot is immune to the possibility of a gear up landing. The best way to safeguard yourself is to discipline yourself in the use of flows, checklists, and call outs. Things like gear warning horns, visual reminders, and other systems are a useful back up, but they shouldn’t be relied upon to save your bacon if you don’t get the gear down at the proper time. Fortunately, in most gear up landings, the pilot and passengers are able to walk away uninjured – but that doesn’t lessen the embarrassment or financial burden of the event. So, keep your chin up, your gear down, and remember….THREE GREEN

Conroe, TX CPPP

0 Comments

The Cirrus Pilot Proficiency Program (CPPP) will be coming to the Galaxy FBO at the Lone Star Executive Airport in Conroe, TX again this year.  The dates of the event will be October 14th-16th.

Wondering what the CPPP program is?

“CPPP offers a weekend event for Cirrus owners and their partners that focuses on Cirrus-specific knowledge and flying proficiency.  We bring some of the most experienced flight instructors who regularly teach in all kinds of Cirrus airplanes flown for all kinds of missions.  We have prepared an extensive syllabus of ground courses that complement the transition training and delve into areas of greatest need for Cirrus pilots.” (from CirrusPilots.org)

CPPP

The weekend starts off with a group dinner on Friday night. The Saturday morning ground session focuses on General Aviation Safety with special focus on the Cirrus accident statistics.  Normal and emergency procedures are also reviewed.

In the afternoon on Saturday, the attendees are split into two groups.  The first group has a myriad of options for ground sessions covering all topics related to Cirrus aircraft and operations.  The second group flies, then they switch for the second 3 hour session.  Sunday brings the same split, with more courses offered and more flying.

While the Cirrus pilots are flying and learning more about their airplanes, CPPP offers a Partner in Command course for flying partners on Saturday.  This allows flying partners to be more comfortable in the airplane and teaches them what to do if something were to happen to the pilot.

All in all, attending a CPPP will improve both Cirrus knowledge and Cirrus flying skills.  It’s highly recommended for all Cirrus pilots.

To register for the CPPP event in Conroe, check out the CPPP website.

Simplified Instrument Approach Briefing

0 Comments

In instrument flying, I am all about keeping things simple.  There is a ton of detail that an instrument pilot can get bogged down in.  When an instrument pilot gets bogged down, he gets distracted from flying the airplane.  When he gets distracted from flying the airplane, dangerous circumstances can happen.

I like to keep things simple.  When I first started instructing, I developed a very simple instrument approach briefing that captures everything that is necessary on an approach plate, but prevents getting bogged down in the details.

I call it the BBC instrument approach briefing.  Here it is:

Brief

rnav-32-kssfFirst things first.  The first step of an instrument approach briefing is to brief the approach plate.  There are a bunch of acronyms out there that instructors tell their students to memorize that only cause confusion instead of helping get the plate briefed.  To keep it simple, just work your way across the plate and you’ll get all the information you need.

Start in the top left hand corner of the plate, with the approach course, then work your way right and down, as follows:

  • Approach Course (or Nav frequency if flying a VOR/ILS/LOC)
  • Runway information
  • Notes (these are good to brief the night before as a lot are irrelevant to GA pilots
  • Missed approach
  • Frequencies
  • Planview and MSA
  • Profile View and Minimums

Simple enough, right?

Build

Now that you know what you are planning on doing, you can now take the second step in the instrument approach briefing and build the approach in your GPS.  You know your approach type, you know your transition, and you know what your minimums are.  Taking all that information, you can now build it in to your system.

Checklists

Once everything else is done, don’t forget the checklists.  The descent and before landing checklists still need to be done as part of an approach.  The best time to do these is before joining the approach so that you don’t have to worry about flying the approach and looking at a checklist at the same time.  Even better, memorize the checklist and you don’t have to look at anything!

Most importantly, you want to be configured properly for the approach by the final approach fix.  Gear, flaps set, power set, so all you have to worry about at that point is following the needles and trusting your instruments.
