The Flight Checklist of Hot Air Balloons

Mathematics Involved...

As can be seen from this checklist, there are only a few mathematical influences on the launching and piloting side of hot air ballooning. Basically, it comes down to the following: how much weight will I take on the flight, how long can I fly and when can I launch. Everything else, is basically safety/common sense. Finding an appropriate area to land, may need a little figuring, only in the sense of knowing if there is enough room to disassemble the craft.

A typical checklist would contain the following items:

1. Always - Before Flight Checklist

1. Balloon within Annual 100 Hour Inspection Period

Safety check included on this list as a reminder to not fly if it hasn't been checked recently.

2. Weather Brief (WillbanksRule 93/SW8/WA15)

The rule is, if it isn't perfect conditions, then ask yourself..."When I'm up there, would I rather be down here?". If the answer is even remotely, yes, you don't launch. It is much better to be on the ground, wanting to launch (and not launching) than to be in the air and wanting to land.

3. Load Check - Never more than 700 lbs. of "Human Flesh".

Weight Limits

Weight limits are unique for each balloon: The size of the balloon and the inclusion of standard equipment (i.e. propane tanks filled, basket, etc) will yield a "not to exceed" weight that can be included.

That is the starting point. Since the lift is determined by the buoyancy of the air, air temperature and pressure must be factored into the equation. The time of day will also impact the air temperature, external to the balloon as well as internal, as the balloon can absorb heat from the sun. There is a limit to the elevation of the sun above the horizon (30 degrees) that balloonist adhere to where they will not be in the air after that point of time. All ballooning is confined to the hours just after sunrise and just before sunset.

This particular checklist was setup for a balloon that was designed for about 1,200 lbs. Taking into account the fuel, basket etc., the balloon is conservatively limited to 700 lbs. of personnel.

4. Launch Site - Check for obstacles downwind. Check for Power Lines. Get Landowner OK's.

Safety check to determine how fast altitude must be gained to clear obstacles. Special not is made for power lines, as these are not as easily visible in the air.

5. Fuel Planning - Flight Time Rule: "Sun not more than 30 degrees from the horizon"

The fuel tanks are used conservatively. Must plan to leave at least 25% of the fuel taken on board. With 4 tanks, this means 1 tank should also be available, just in case...

The sun rule, normally means that launch and flying should be within 2 hours of sunrise or sunset.

6. Wind Direction - Landing Area - Test helium balloon (Piball)

Test belloons are used to determine the amount, direction and altitude of the winds for that day. Note than when one is flying, there are always the possibility of finding thermal areas that will allow for changes in the direction of the wind at different locations and altitudes.

7. Envelope Placement Downwind

Initial ambient temperature air is blown into the balloon to fill it out. An additional fan is used to accomplish this. (takes about 10 minutes, depending on size of the balloon and the fan) This cannot be accomplished unless the balloon is downwind.

8. Necessary Documents Onboard - Flight Manual, Air Worthiness Certificate, Registration and Pilot's License, Area Map, Sectional Chart - Detail of Red Zones.

9. Functioning Communication Equipment (Radio, CB, FRS, etc.)

You must have communication with the ground team in order to plan for landing. Please note, that although cellular phones can be used, since cellular is specifically a terrestial based system it should not be used from any aircraft.

Up to this point, only the components have been taken out of the trailer and the basket items checked. If the weather or the site chosen to take off from are not acceptable, the launch can be scrubbed. From discussions with balloonists, usually only 1 in 10 tries will you be able to take off.

2. Layout and Inflation

1. Brief Crew and Assign tasks to each

Management....

Setup, ready for inflation of the envelope.

3. Secure anchor tie-off

Don't want to have the balloon drifting around on the ground, before launch.

- Color Coded Cables; "Head" nameplate alignment, Vent velcro tabs, Pyrometer connect, Loose vent line tie to basket, Inflator fan position, Fan Stabilized

The basket gets attached at this point. Note the pyrometer connection, to allow for determination of the temperature of the flame/hot air. The fan is setup to allow cold inflation of the balloon - i.e. prior to heating the air.

5. Cold Inflation - to "tight and fat" the envelope

Using the fan, inflate until the envelope, still on the ground, is as tight as possible.

6. Envelope Inspection for Integrity

Safety check...

7. "Thumbs Up" to Crownline Crew prior to Hot Inflation

Acknowledge the crew that hot inflation will start, so the lines attached to the envelope, to keep it from getting away will be manned.

8. Hot Inflation: Pilot and Top Two Tanks ON

- Reduce Inflator fan speed and place back of basket

- Light Pilot - Initiate Burner

- Caution fo Fabric, Cables, Rope and Crew

- Burn until balloon is upright and tight--"Hands On, Weight On"

3. Pre-Launch Checklist

1. Envelope Inspection

Safety check....

2. Check Rigging - Crownline "Tie-off" -- Seal(pull) Vent / Parachute

Verifying the parachute valve is fucntional.

3. Set Instruments -- "Hands and Weight On"

4. Fuel Tank Check - All Tanks..Close Tank #1, Open Tank #4,

..Close Tank #2, Open Tank #3,

..Close Tank #3, Open (return) to Tank #2

Start Flight on Diagonal Tanks #2 and #4

Checking out the tanks. Use opposite corner tanks to balance the load as the propane is used Otherwise the basket will be uneven.

5. Radio/Communications check ...frequency coordination ...\$0.25 coin? ...cell phone #'s.

Verification of the radios back/forth and on the correct, agreed to frequencies (codes). Backup #'s and quarters in case you have to come down and your crew can't locate you. (other communication failure...)

6. On-board equipment check ...strikers, fire-extinguishers, drop-line, velcro-tie for burner, wrench, screwdriver, gloves and clock

Basic equipment to be able to restart burners, put out any fire, rope and various tools, just in case...

7. Crew and Passenger Briefing ...Ask Crew: "Who has the keys?"

Basically, who is going to be piloting. Everyone else is a navigator.

8. "Hands On - Weight Off" - Equilibrium Check

Bump up a little from the ground (while still being held by the lines) to check the stability of the basket with all aboard.

9. Release of tie-down anchor

10. Downwind Walking Launch

The crew will walk with the ballooon down wind, as it begins to lift off. They will keep the speed to a walking speed (< 2miles per hour)

11. Burn for Obstacle Clearance

Run the burners fast enough/long enough to clear all the immediate launch obstacles.

4. Inflight Checks

1. Fuel Management - short burns

2. 30-minute fuel gauge check ...burn to 15% then switch tanks

3. Switch from tank #4 to tank #1

As Tank 4 is used up.

4. Obstacle Avoidance

5. Landing Site Evaluation

6. Switch to final full tank, #3, prior to approach ...Close #2 - Open #3

5. Landing Approach Checklist

1. Alert Crew and Passengers ..."Help Look for Power Lines"

2. Landing Abort / Missed Approach Plan

3. Parachute Vent (or valve) Line

4. "Hands Inside and Low" - "Flex Your Knees" - "Hold on Red Tie Straps Inside Basket"

Safety check, no limbs outside of the basket to avoid injury.

5. All Passengers stay inside basket until balloon is stable and wait for Pilot's Instuctions

6. Post-Landing Procedures

1. Pilot and Burner Off ...Call for "No Smoking"

2. Cool Burner with Propane Blast

3. Fuel Valves Off

4. Bleed Fuel Lines

5. Crownline Down Wind

6. Release Parachute Vent ...Allow Ballon to chimney

7. Dissassemble and Storage

8. Landowner Relations - GBA Raffle...

Make sure you have something for the landowner (if not known beforehand) where the landing occurred.
