Am I too fat to soar? (Read 949 times)

So I know at some point in the future I'd like to do some kind of piloting.  I will probably go for PPL, and while I probably have the time to do it now, I'm not motivated enough and I don't want to spend the money or the time to get the license if I'm not going to fly much (which I won't).  I only see myself flying in the area every now and then, not really travelling that far, and even then only doing it on nice days.

I've always been intrigued by soaring and I think it would be excellent for me.  Much less expensive to learn and do, and it's easy enough to go get in a glider and tool around for a little bit on a nice day.

But there's a problem: I weigh 240 pounds, on a good day.  When you factor in clothes and shoes and whatever, it's more like 250.  I need to lose weight, and am trying, but if I wanted to start gliding tomorrow, would I be able to?

The same question goes for sport flying.  If the flying club adds sport pilot training (they just got a Skycatcher a few months ago), I may go for that, but MTOW of a Sport plane is 1320 lbs, so if I take up 250 of that, would I be able to fly with an instructor?

Any input is appreciated

From my experience you shouldn't have a problem learning in a C172 when I looked in to it it said people over 196lb need to use a 172 and there wasn't really an upper limit. It was just more expensive for the bigger aircraft.
I 5 8' and 161 pounds so I can squeeze myself in to 150 if needs be.

At that weight Jake, you are likely to have a two fold problem when it comes to gliding. Firstly, the glider will have an all up max weight so you need to factor in the instructors mass too. Secondly, a ASK 13 for example is a tad C of G sensitive. To overcome this, you can bolt in lead ingots in either the forward or aft cockpit. That then puts you back in all up max allowable. Another small problem will be the cockpit size against you own frame. Don't forget that when gliding, you will be required to put on a parachute and that adds around four to five inches to the depth of your back. Due to the size of said chute, they also have a max all up. When I started gliding in 1990 I was on the limit and could only fly with two of our instructors. It was a good incentive to lose a few pounds. Best option right now, help your heart out....It is amazing how much money you save by cutting our the chocolate, crisps and biscuits too Smiley

I'm working on the weight. I don't know that my size would be much of a problem, I'm not that big considering how much I weigh, and I'm only 5' 8".. I was more worried about cg and mtow issues.

I don't know much about gliders, but I do know that at your weight, you can fly a 172 no problem, even with an Instructor, and an assortment of other aircraft. I myself am 6'1" and as of right now, I weigh 231.4lbs, haha, it's only precise because 1) I'm trying to lose weight, and 2) I weighed myself this morning. During my training, the heaviest I got was 250lbs, and in the summer, for my medical, I weighed in at 248lbs. As well, a few summers ago I was about 240lbs, and took up a 260lbs passenger. Chances are your Instructor will be a relatively light person, probably around 165lbs avg, and if you get your PPL, then you can fly LSAs as well as other aircraft.

It depends on the glider... and no, you don't need a parachute.
With the Schweizer SGS 2-33 I fly, with me (at about 180 with my shoes on) in the back and you at 240 in the front, that would leave us about 30 lbs.below max gross weight, and within the balance envelope (albeit in the forward corner). That would be about my personal limit. But not the absolute limit-the glider will fly OK with even slightly more weight in both seats.� The bigger worry would be if the heavier pilot was in the rear seat... it's easier to fly it safely if it's a bit nose-heavy, but not the other way around.
Some 2-seaters are skinnier, but the 2-33 front office, although narrow, can accommodate pretty wide hips. Tall people do OK in that seat, also.
Not so the rear seat...� the front seat is like a canoe, the rear seat is like a holster.� Grin
Some advice: as a thumbnail rule, if you take an intro flight in a 2-33, if the pilot is lighter than you, make sure they sit in the back. The back seat is no good for first-timers anyway- the view is not so good, and it's harder to get in and out; unfair if you are bigger.� If you were a little kid or other lightweight person, the front cockpit has a spot for a ballast to be mounted, to bring the CG forward a bit more, making the glider more manageable.
Having learned to fly our old 2-33, I sometimes wish I'd started in one. It is ponderous, at first, compared to the average light single-engine plane, but once you figure it out it is very satisfying to fly. I have seen 13-year olds tame that beast faster than I did... it's designed to teach you to fly without getting you in too much trouble.

Fortunately for you, these trainers are still plentiful; probably the most common trainer in the USA these days.

So go for it. I made a similar decision myself, after realizing it wasn't making sense to spend so much on my usual "proficiency runs"... especially when the economy croaked, I lost my job, etc... soaring satisfies for less money, and my core skills are not rusting, believe me.

You should also consider getting the PP-Glider; about half the cost and trouble as the PP-ASEL on average, even for "raw recruits". Should you decide to get the power rating later, you'll be able to use some of the flight and instruction time logged for your glider rating, but you will still have to deal with the written and oral exams. Power flying is just more complicated... but if you can fly a glider well, you will have an edge when it comes to the real basic (but supremely important) stuff: stick and rudder, looking outside, thinking ahead, etc. And earning the PP-G will leave you more confident prepping for the ASEL exams.

EDIT: I forgot to mention, regarding weight loss, that soaring is a sport. Seriously. Flying in thermals while looking and thinking is work, and when you're not doing that, you're hanging out in the sun, maybe doing ground chores. You don't see many- how shall I put it- lardasses flying gliders on a regular basis.  Wink  I definitely lose flab every season; you will, too. Get yourself down to 220, and at 5'8" you'll be perfect material to someday give rides and instruct from the rear "holster" of a 2-33.  Grin

Must be different in the USA. I have never seen a pilot in a glider here in Europe or the UK fly without one. In fact go to a club and refuse to wear one, you will not fly. It is only a legal requirement if you enter cloud, but as far as club insurance goes it may as well be a legal requirement.

Just go training: go swimming, running, fitnessing.
my doctor doubted to pass me at my medical examination because i was too light, i'm 15 and I weigh 45kg ( 90 pounds). in my glider, I have to add 28 kg to get it right.

But truly, there is no more awesome sport than soaring� Cool , go do it every weekend and go solo ASAP!� Wink

I wouldn't. There was a chap in the 90s who was glad he had one, as somewhere over Berkshire his glider disintegrated around him (stray lightning IIRC!)...

Mind you, it's amazing how many people, particularly in private aviation, will resist spending money on anything that'll save their life. They'll happily spend �1500 on an all singing, all dancing super GPS system for example, but won't spend it on a transponder (which could save a whole lotta lives) or chute.

No worries about lightning with a 2-33... the wing is aluminum and the rest is steel tubing. Wicks are not required as there is no electrical system or fuel to protect. Composite gliders, unless they have lightning protection built in, are extremely vulnerable to lightning, as they are not sufficiently conductive for the bolt to continue on its path. So all the energy goes into the structure. Burns and explosive delamination are typical results.
Regardless, it's still possible to get zapped in a steel-frame or aluminum airplane, so as a rule I try to avoid storm cells.� Wink
As for a parachute: if I were penetrating clouds, competing with large groups (where dozens of fast gliders might be sharing a thermal) or doing aerobatics, I would consider it. But the odds of the controls or structure failing on either of our Schweizers, the way we fly them, is slim indeed. They are tough. There is at least one� case known to me of a 2-33 losing most of one wing ( a midair with another glider; can't seem to find a link to the story anywhere, dammit), which ended with the glider spinning in like a maple seed from several thousand feet up, into open terrain. The pilot was injured, but not very seriously. If I remember right, she was able to get herself out of the wreck. That steel frame is all about protecting the occupants. Bailing out might have not been so simple, or ended with less injury.
  At the altitudes I typically fly (below 5000 AGL), even in a collision scenario, a parachute would be almost useless.� First you have to determine if you need to get out (which means several hundred feet lost), then you have to open the harness and the canopy (which can be jettisoned, but only partially- a potential hazard)... more precious altitude lost... then you have to squat in the seat, then jump clear, without hitting the wing strut, wing, or tail on the way out. That's in the front seat. If I were in the back seat, I'd probably never get out, especially if the glider was spinning or tumbling. The rear-seater's legs straddle the front seat, the wing is overhead, and there's only a tiny door for egress.  In any case, I'd then have to wait for the canopy to open, then make sure I have time to steer clear of any of the numerous hazards below my usual gliding areas. All in all, a pretty risky proposition- not at all like making a planned jump from a stable jump plane at 8000  feet or more.
But as I have said more than once, if I had to "auger in" in any aircraft, I'd want it to be a 2-33. The single-seat 1-26 is also very strong, if a little easier to get out of.
The transponder thing I can't argue with much, but they are expensive and add weight (including the weight of the batteries). But if the club were contemplating buying other bulky panel-mounted goodies for either glider, I'd suggest a transponder instead.

I waited for beaky's response before adding my two penn'orth. I found an article which seems to confirm that gliding club rules in the US are indeed different from those in Europe. http://continuo.com/marske/COSA/parachute.htm
COSA is the Central Ohio Soaring Association.

I appreciate what you're saying about difficulties exiting the rear seat but an incident at Duxford last year proved the value of wearing a parachute even when used at extremely low altitude. Before seeing this I would have thought it impossible. http://www.dailymail.co.uk/news/article-2013219/Pilot-Rob-Davies-escapes-WW2-fig...

Rob Davies said afterwards that his chute opened at about 300 feet. I was told that he was one of the few warbird display pilots to wear a parachute & regularly practice using it. I suspect that situation will change now.

PS. The parachute he used is the same lightweight type as worn by aerobatic & glider pilots.

A point that I missed as Hagar pointed out with Rob Davies,�parachutes designed for gliding, the advert says that as long as the rip cord is pulled no later than 300 feet, you will survive, walking away is another matter, though Mr Davies did. They have been proven quite a few times. The power of the deployment spring is something to be seen. I had a friend who was sat in in his car with is legs out the door. His 3 year old pulled the rip cord. The chute deployed and shattered the passenger window. Saying that, I would not want to put it to the test............

Matt

PS I wonder if these guys (http://continuo.com/marske/COSA/parachute.htm) have had the airbags removed from their cars, maybe the bumpers too  Roll Eyes Huh Grin

In the states it's probably less of an issue as you have a lot of air to share. On our little old island, where airspace (particularly uncontrolled airspace) is precious and limited, you end with a lot of users in a very small space. Sadly, a fair proportion still believe that "see and avoid" will keep them alive...

...and off the top of my head I can think of at least 5 GA mid air collisions in the relatively recent past in the UK. Huh
