Guides

The parts of soaring that nobody hands you a manual for — written for the people doing the job, with the arithmetic shown, nothing gated.

If you're thinking about starting

If you fly

What actually gets badge claims rejected

5 min

They fail on evidence, not on flying — and nearly all of it is decided before you launch.

Cross-country pilots and Official Observers

Buying a glider: where to look, and what to check

5 min

Where the market actually is, what the inspection must cover, and the one finding that should end the conversation.

First-time buyers and syndicate members · has a calculator

Your 3,000 ft field is performing like 6,000 ft

4 min

An aerotow suffers at both ends of the rope. What a hot day at a high field actually does to your launch.

Pilots, tow pilots and ops officers · has a calculator

How gliding contest scoring actually works

10 min

Your score depends on other people's flying, and there is a cliff at two thirds of the winner's speed. Both are deliberate.

Competition pilots and anyone scoring one · has a calculator

Reading a glider polar

9 min

Two tangent lines explain almost everything — including why the polar tells you to carry water on a two-knot day.

Cross-country pilots and instructors · has a calculator

What a refinish costs, and when it is worth it

7 min

Budget in labour hours, not dollars. For many 1970s ships the job costs more than the aircraft is worth.

Buyers, owners and club fleet managers · has a calculator

FLARM, ADS-B, and what actually sees you

7 min

You are legally exempt and electronically nearly invisible. Those are the same sentence, and only one of them is the point.

Pilots and club committees

Wave windows and Class A airspace

7 min

Everyone calls it a waiver. It is not one, and understanding what it actually is changes what you think it covers.

Wave pilots and the clubs that host them

Oxygen for glider pilots

7 min

The legal thresholds were written for aircraft that pass through altitude. A glider sits there for three hours.

Anyone flying high, and anyone planning to · has a calculator

Self-launch and motorglider endorsements

7 min

No rating exists. Three endorsements do, the guidance everyone cites was cancelled, and currency has a gap worth naming.

Motorglider owners and pilots considering one

Importing a glider into the United States

7 min

Freight is a solved problem. The de-registration standoff in the middle of the paperwork is the part that strands aircraft.

Buyers looking at the European market

The retrieve

8 min

The logistics half of landing out — trailers, crew, landowners — which is where nearly all the friction actually lives.

Anyone thinking about their first cross-country

If you help run a club

What a tow should actually cost

8 min

Fuel is under half of it. Where the rest goes, and how to set a tow fee on purpose rather than by inheritance.

Treasurers and committees · has a calculator

Choosing club management software for a gliding club

6 min

Including when the honest answer is a spreadsheet, and where we are the wrong answer. No competitor price table.

Committees evaluating options

The duty roster problem

6 min

Why six people end up doing everything, and what a roster is actually for. It is not filling slots.

Committees and ops officers

Why students quit

6 min

They rarely lose interest. They lose access. The arithmetic of launch rate, and how to spot the students you are about to lose.

CFIs, committees and instructors · has a calculator

The gliding club treasurer's year

6 min

Month by month, what needs doing and when — and the things the outgoing treasurer knows that were never written down.

Treasurers and incoming treasurers · has a calculator

Turning trial flights into members

6 min

The flight is rarely the problem. The fortnight afterwards is, and in most clubs nobody owns it.

Committees and anyone flying visitors · has a calculator

When one volunteer holds the club together

6 min

Being indispensable is a risk to the club and usually unfair to the person. What gets lost, and how to hand it over.

Committees and outgoing officers

Where your club's legal documents actually come from

4 min

Insurer first, national body second, a lawyer once. Why we do not publish templates, and the checklist of what to ask for.

Committees and club officers

What your club owes the IRS

7 min

Intro-flight income has a ceiling, your reserve fund's interest shares it, and sloppy records shift the burden of proof onto you.

Treasurers, presidents and committees · has a calculator

Replacing the club trainer

7 min

A club can look solvent for twenty years and be insolvent the whole time. The reserve arithmetic, worked.

Treasurers and committees · has a calculator

How clubs price membership, and what it does to who joins

8 min

Your fee structure is choosing your membership every year, whether or not anyone decided that it should.

Treasurers and committees · has a calculator

Unleaded avgas and your tow price

7 min

100LL goes by 2030. Your tug's engine is the easy part — and its duty cycle means your club may come out ahead.

Committees, tow pilots and treasurers · has a calculator

Who is left in the sport

8 min

The sport's own numbers on its own ageing. Worse than expected at one end, better than expected at the other.

Committees, and anyone arguing about decline · has a calculator

Run the numbers for your club

Several of these have a calculator behind them — what a launch costs you to provide, and what learning to fly costs a member. Both are free and take your own figures.

Sitting the written

Most of the FAA glider knowledge test is recall, and the rest is arithmetic that gets taught as charts to read rather than relations to understand, which works right up until the chart is not in front of you. The practice page does both: the calculations with the working shown and the calculator that does each one, and a question bank for drilling the recall.

What clubs actually charge

Not a guide, and the only page here that is primary data rather than writing: the published rates of 34 US soaring clubs, read off each club’s own website, every figure linked and dated, and left blank wherever a club publishes nothing. The median tow to 2,000 ft across the 22 that publish one is $40.

If a word gets in the way

These are written to be readable before you have the vocabulary, but soaring has a lot of it — and some of it means different things either side of the Atlantic. The glossary covers the terms that turn up here most.

Something missing, or something wrong?

These come from watching clubs run and getting the arithmetic checked. If your experience is different, or there is a problem you keep solving that nobody has written up, tell us — that is how the next one gets chosen.
