HappeningsBy Joe Scaglione

September Membership Meeting

Here’s somemore infoabout aNavyplane thatwasdescribedat lastmonth’smeeting;it had props and a jet engine. Itwas aNorthAmericanAJ2Savage. Designed in about1951 and built in 1953, it had two Pratt & Whitney R2800s and a J-33 Allison jetengine. On this plane, the jet was retractable and only deployed when needed. It flewwith a single pilot and a radarman. Itwas the first naval plane to carry the atomic bomb.It was used until the early 1960s when it was surplused and the test bed was bought byLycoming and used as a fire bomber. And another interesting fact was that our ownSherman Corning flew as a flight engineer in its testing phase.

The Membership meeting started off with guests from the Pathfinders. We hadflown over one hundred of them this pastMarch.Ms.Taylor, who is their local leader,brought the Regional Director, Calvin Brooks and the Youth Director, Rev. PedroPerez of theSeventhDayAdventistChurch. They had come to present awards to thechapter and pilots and ground crew for service to their organization. A plaque with allthe pilots’ nameswas given to PresidentBill Siegel, and individual plaqueswere givento each pilot; many of the pilots were not in attendance, as they came from otherchapters. Certificates were also given to the ground crew.

On a light note, there had been a mistake with one of the plaques, the one for ourTreasurer, Bud Smith, who flew that day. Well there was a boo-boo on his plaque. Itseems they misspelled his name and it appears as "Bad" Smith. So a suggestion wasmade to leave the spelling and fromnowonhewill be referred to as "BadA__ Smith.”I think as a personal thought that these people have thanked the chapter in the very bestway I can remember.

As the meeting got on, Jim Cook gave us some insight as to flying and using ourchecklists, relating an incident that he just had putting his Venture back in the air afterabout a year on the ground. Jim's message is to use the checklists, nomatter howmuchexperience you think you have.

Our own Paul Hershorin, the director of the BASA program, has let us know that Embry-Riddle has kicked him upstairs and he is now the director of their whole high school program.Finally the chapter video was presented. It was a quick tribute to the volunteers of Oshkosh anda short feature about the GB-QED replica racer.

September Board Meeting

The meeting was held on September 10th at the Metro Embroidery Shop on IndiantownRoad. In attendance were Rick Golightly,Kevin Sheely, Bill Perry, Ed Dolezal, Bill Siegel,Bud Smith (his new name is "Bad", as explained in the report of themembershipmeeting), JimCook and Joe Scaglione. This is Jim Cook’s last Board meeting, as he has given up the postof Membership Coordinator. The new Membership Chair is Kevin Sheely. Kevin will alsoassume the duties ofHangarMaster. Jim is stepping aside because, as many people know, heand some partners are reviving the Questair kits business. The board wishes him well in thisendeavour. Thiswill not be goodbye though. Hewill continue to be amember of the chapter andmake frequent trips back to Palm Beach from Mississippi.

The Young Eagles that was scheduled for this month at Belle Glade has been postponed fora date still to be determined and will be moved probably to Pahokee. Therewas another Young Eagles flight several months ago at Boca Raton. Wewill be flying the same group again sometime in October, but it will be atNorth County Airport (F45).

Here's the answer to last month's aircraftidentification question

The Thomas-Morse MB-7 was an American racing planebuilt by Thomas-Morse Aircraft for the US Navy.Development and designThe MB-7 was built on the request of the US Navy. Theyhad recently received the Thomas-Morse MB-3, and askedB Douglas Thomas to modify two of them to be racers.The first MB-7 was completed in 1921. It took part in the1921 Pulitzer Trophy race, but during the race its fuel

pump malfunctioned and it crashed and was destroyed byfire when a lighted match by a souvenir hunter ignited thefuel. The second MB-7 was completed in January 1922. Itfirst flew in 14 April 1922. It competed for the US Navy inthe Pulitzer Trophy on 14 October 1922. Piloted byCaptain Francis Pat Mulcahy it withdrew after 30 minuteswith an overheating engine. It never flew again beforebeing dismantled on 7 January 1925.

1. The left turning tendency of an airplane caused by P-factor is the result of the

A. propeller blade descending on the right, producing more thrust than theascending blade on the left.

B. clockwise rotation of the engine and the propeller turning the airplanecounter-clockwise.

C. gyroscopic forces applied to the rotating propeller blades acting 90° inadvance of the point the force was applied.

2. What effect does high density altitude, as compared to low density altitude,have on propeller efficiency and why?

A. Efficiency is reduced due to the increased force of the propeller in thethinner air.

B. Efficiency is increased due to less friction on the propeller blades.C. Efficiency is reduced because the propeller exerts less force at high

density altitudes than at low density altitudes.

3. The amount of water vapor which air can hold depends on the

A. dewpoint.B. air temperature.C. stability of the air.

4. What action is required when two aircraft of the same category converge, butnot head-on?

A. The aircraft on the left shall give way.B. Each aircraft shall give way to the right.C. The faster aircraft shall give way.

Answers are on pages seven and eight.

1. Answer A is correct.

The left turning tendency of an airplane caused by P-factor is the result of thepropeller blade descending on the right, producing more thrust than the ascendingblade on the left. This is the definition of P-factor.

This whole question is a 'definition' type question. The clockwise (as viewed fromthe cockpit) rotation of the engine and the propeller turning the airplane counterclockwise does indeed turn the airplane to the left. However, this phenomenon isknown as torque, not P-factor.

Obviously, a propellor turning in the opposite direction will produce a turningmoment to the right.

Gyroscopic forces also turn the airplane to the left as described. However, this isknown as gyroscopic precession, not P-factor.

Reference: AC 61-23, Chapter 1

2. Answer C is correct.

High density altitude implies non-dense air, such as at high elevation or on hot days.

High density altitude decreases propeller efficiency because the propeller exerts lessforce--that is, it has fewer air molecules to throw backward-than at low densityaltitudes.

Efficiency is reduced due to the decreased, not increased force of the propeller inthinner air (read carefully!). There may be less friction on the propeller blades due toincreased density altitude, but since you'd like to have the propeller throw back moremolecules, the cumulative result of this is the lessening of propeller efficiency

3. Answer B is correct.

The warmer the air mass gets, the less dense it is, thus allowing the potentialfor water vapor in the air mass to increase. The warmer the temperature, themore water vapor, or moisture, can be present. The mixing ratio defines howmuch water vapor actually exists (NOT dependent on temperature). Thesaturation mixing ratio defines the capacity, or potential, of how much watervapor can be present, dependent on temperature. The greater the temperature,the greater the saturation mixing ratio. Relative Humidity is the ratio betweenhow much water vapor exists, and how much water vapor can exist given thetemperature. If the two are equal, the RH must be 100%. 100% Humiditymeans the air has as much water vapor as it can have.

Reference: FAA Subject Code: I24 - Moisture, Cloud Formation, andPrecipitation

4. Answer A is correct.

In theory, things are supposed to work like a four-way stop sign in the US.Note how the red light on the left wingtip of the aircraft on the right acts asas a sort of stop sign to the other aircraft. Sailors and boaters will recognizethat the right-of-way rules are derived from the corresponding rules of thesea.

This is codified under FAR 91.113 where it is stated:

Converging: When aircraft of the same category are converging atapproximately the same altitude (except head-on, or nearly so), the aircraft tothe other's right has the right-of-way.In practice, since you can never be sure that the other aircrafthas you in sight, it is prudent to always act as if he does not.
