ATIS and AWOS
Weather is one of the most important parts of flight planning. At first, it doesn’t make a whole lot of sense why pilots would care about things like the temperature, dew point, cloud ceiling, etc. Let’s start off with temperature. The outside temperature doesn’t affect the aircraft as much as you would think. However, ice, frost, and density altitude do play a very important part in how an aircraft performs. As you can probably guess, it is not smart to fly with snow, ice, or frost on the aircraft, as the wings won’t produce as much lift, and many instruments just won’t work accurately. Also, a dead engine over the Alaskan Bush or Lake Superior usually doesn’t make for a happy flight (such as a Civil Air Patrol or Coast Guard search). Summer usually has fairer weather, but summer storms can make for very, very bumpy rides. And about density altitude: This name makes little sense, for the higher the density altitude, the less dense the air is. This could better be explained as performance altitude. (As I’m not yet a private pilot, I don’t know a ton on that, but I’m sure that John and Martha King would be happy to sell you a private pilot course.) Now, let’s get to ATIS and AWOS.
ATIS (Automatic Terminal Information Service) is usually found at reasonably large airports with lots of controllers. The controller will record a tape of the last weather update, and put a letter with it. For those of you who don’t speak the Air Traffic Control language, here is the list of letters:
Alpha
Bravo
Charlie
Delta
Echo
Foxtrot
Golf
Hotel
India
Juliet
Kilo
Lima
Mike
November
Oscar
Papa
Quebec
Romeo
Sierra
Tango
Uniform
Victor
Whiskey
X-ray
Yankee
Zulu
Now, let’s look at what this report for Montgomery Field in San Diego means.
Montgomery airport information Hotel, 2159 Zulu. Wind: 238 at 8. Visibility: greater than 20 miles. Sky condition: few clouds at 5,800. Temperature: 18. Dew point: 10. Altimeter 2990. Visual runway 28R and Visual runway 28L in use. Landing and departing runway 28R and runway 28L. VFR aircraft say direction of flight. All aircraft read back hold short instruction. Advise controller on initial contact you have Hotel.
In other words, this is:
Montgomery airport information Hotel, 1: 59 PM Pacific Standard Time. Wind: coming from 238 degrees at 8 miles per hour. Sky condition: few clouds at 5,800 feet. Temperature: 18 degrees Celsius. Dew point: 10 degrees Celsius. Set your altimeter to 29.90 inches of barometric pressure so it will tell you your correct altitude. IFR is using the Visual approach to runway 28 right and runway 28 left. VFR aircraft tell the controller your position, altitude, and intentions. All aircraft acknowledge the hold short of runway instruction. Tell the controller on your first transmission that you have Information Hotel.
For the fun of it, let’s look at this rather unlikely ATIS report for Ronald Reagan/ Washington National airport in DC.
Washington airport Information Charlie, 1256 Zulu. Wind: 012 at 23 gusts at 28. Visibility: 3 miles in snow. Sky condition: ceiling 300 overcast. Temperature: -8. Dew point: -9. Altimeter 2950. ILS runway 1 in use. Landing and departing runway 1. All aircraft read back hold short instructions. Advise controller on initial contact you have Charlie.
This means:
Washington airport Information Charlie, 7:59 AM Eastern Standard Time. Wind: coming from 12 degrees at 23 miles per hour with gusts up to 28 miles per hour. Sky condition: ceiling 300 feet overcast. Temperature: -8 degrees Celsius. Dew point: -9 degrees Celsius. Altimeters should be set to 29.50 inches of barometric pressure. IFR is using the ILS approach to runway 1. Landing and departing runway 1. The airport is currently below VFR minimums. All aircraft read back the instruction to hold short of the runway. Tell the controller on your first radio transmission that you have Charlie.
As you can see, there’s a lot to it, but that’s important. However, you get the hang of it pretty quickly.
For an AWOS (Automated Weather Observing System) report, you’ll hear a computer voice give you the report. Here’s one for Sedona, Arizona.
Kilo Sierra Echo Zulu Automated Weather Observation, 1359 Zulu. Wind: calm. Visibility: greater than 20 miles. Sky condition: Clear… Temperature: 20 Celsius. Dew point: 8 Celsius. Altimeter: 2992.
Now that’s about the best weather that you could hope for. As you can see, the AWOS is pretty self-explanatory.
I hope that you’ve enjoyed reading this!
Keep the pointy side forward, the dirty side down, and by all means, please… stay out of the trees!
Have a great day!

(And yes, King Schools does use Montgomery Field, and yes, the Kings did use Sedona for one of the courses. And I would greatly recommend flight training through King Schools over Sporty’s.)
Hello, aircraft fans!
In this edition of the Plane Crash, we’ll look at the U.S. Navy’s WW2 top three: the Grumman F6f Hellcat, the Vought F-4U Corsair, and the Grumman F4f Wildcat.
A painting of a Corsair at Boeing Field.
Wildcat: Before the greatness of aircraft like the Grumman Hellcat and Vought Corsair, the Grumman F4f Wildcat was a fine aircraft. First built in 1939, this rugged mid-wing 318-mph six machine-gun aircraft held a critical point in the U.S. Navy until better aircraft were supplied. For instance, Lieutenant Butch O’Hare destroyed five Japanese bombers in six minutes. Later, despite being shot down in the Pacific, the Chicago-O’Hare airport was named for him. The Wildcat had a crew of 1, one 895kW (1200hp) Pratt & Whitney R-1830-66 radial engine, a maximum speed of 512km/h(318mph), a range of 1239km (770 miles), and a service ceiling of 10,638m (34,900ft).
An excellent photo of a squadron of Wildcats during WW2.
Dimensions are as follows: Wingspan: 11.58m (38ft.). Length: 8.76m (28ft. 9in.). Height: 3.61m (11ft. 10in.).
Armament: Six 12.77mm (0.50in.) machine guns in wings and an external bomb load of 91kg (200lb.). Total loaded weight was 3607 kg (7952lb.).

Hellcat: The Hellcat flew for the first time on June 26, 1942. Many of its war abilities had been learned from its predecessor, the Wildcat. Specifications for this war-changing plane are as follows:
Crew: 1.
Powerplant: one 1492 kW (2000hp) Pratt & Whitney R-2800-10W radial engine.
Performance: Maximum speed: 612 km/h (380mph). Range: 1521km (945 miles). Service ceiling: 11,369m (37,300ft.).
Dimensions: Wingspan: 13.05m (42ft10in.). Length: 10.24m(33ft.7in.). Height: 3.99m (13ft.1in.).
Armament: six 12.7mm(0.50ibn.) machine guns in wings, or two 20mm(0.79in.) cannon and four 12.7mm(0.50in) machine guns, provision for two 453kg (1000lb) bombs or six 12.7cm (5in) RPs.
Weight: 7025kg (15,487lb).
In all, the Grumman F6f ran up a 19 to 1 kill ratio.
As the sun sets over the Pacific, these Corsairs return home.
And now: the Chance Vought F4U Corsair. The speed, strength, and firepower of the Corsair enabled it to dominate Japanese opposition, shooting down 2140 against a loss of 189. Its performance and dependability allowed great flight leaders like John Blackburn, John Smith, Marion Carl, Joe Foss, and Pappy Boyington to create legendary fighter squadrons. It was truly a superior aircraft.
Have a great day!

Hello, aircraft fans!
In this edition of the Plane View, we’ll take a look at the long line of Grumman aircraft. From the ’31 FF-1 to the EA-6, we will see how Grumman has one of the longest lines, and also is one of the best.
A painting of a Grumman at Boeing Field.
And now: The Grumman FF-1. The FF-1 was a Golden Age aircraft, and still served in the Spanish Civil War on the Republican side. It had a crew of one, a 709kW(950hp) Wright R-1820-22 Cyclone 9-cylinder radial engine, a maximum speed of 418km/h(260mph), a range of 1819km(1130 miles), a service ceiling of 9845m(32,300ft), as well as a wingspan of 9.75m(32ft.), a length of 7.01m(23ft), and a height of 2.84m(9ft.4in.). The weight was2155kg(4750lb) loaded; an armament of one 12.7mm(0.50in) and one 7.62mm(0.30in) machine gun in upper forward fuselage, as well as an external bomb load of 105kg(232lb.).
The Grumman G-12 Goose was a high-winged, amphibious aircraft with retractable landing gear, as well as a crew of 2, and a variable payload, changing depending on whether passengers or freight was being carried. A few are still in service today, as they are a grand old plane, first built in 1937.
Although the greatness of aircraft like the Grumman Hellcat and Vought Corsair, the Grumman F4f Wildcat was a fine aircraft. First built in 1939, this rugged mid-wing 318-mph six machine-gun aircraft held a critical point in the U.S. Navy until better aircraft were supplied. For instance, Lieutenant Butch O’Hare destroyed five Japanese bombers in six minutes. Later, despite being shot down in the Pacific, the Chicago-O’Hare airport was named for him.
The Grumman TBF Avenger was an effective dive-bomber, being second only to the Douglas SBD Dauntless. On the fighter side, the Grumman F6f Hellcat, which won the war in the Pacific, the F7f Tigercat, and the F8f all proved to be at least worthy aircraft.
Search and Rescue: The SA-16 Albatross of ‘47 and the S-2 of ’52 both were excellent, the SA-16 being S&R and the S-2 being submarine-killer. But the E-2 of ’60 surpassed both, in the way of searching for enemy aircraft.
Back to fighters: the F9f, F11f, and F-14 all proved to be sufficient for their time. The F-14 Tomcat had more than 30 years of service, but has now been replaced by the Boeing/McDonnell Douglas F-18 Hornet.
Lastly: the Grumman A-6 Intruder and EA-6 Prowler are the best attack-radar jamming aircraft ever. The current Prowler is greatly needed, as skies are again becoming hostile (get ready for World War III!

British Aircraft History
Hello, aircraft fans!
In this edition of the Plane View, we’ll take a look at the British hero aircraft. As the British “royal baby” has recently been born, I thought it would be fitting to do a post on the British aircraft fame.
Dating back to World War 1, England has been a world leader in the aircraft industry, with such greats as the Sopwith Pup, Sopwith Camel, Sopwith Snipe, the age-opening Sopwith Triplane, Royal Aircraft Factory FE.2b, and Royal Aircraft Factory SE.5. The famous Sopwith Camel, flown by such greats as William Barker, Roy Brown, Wilfred “Wop” May, and Snoopy (on his doghouse), was much like the German Messerschmitt Bf 109 Gustav, in the fact that both were feared by the enemy and the pilots. On the other hand, the Sopwith Pup was arguably the sweetest of all World War 1 aircraft to fly. The Royal Aircraft Factory SE.5 was the Supermarine Spitfire of World War 1, about as high of praise as a plane could get.
A picture of Snoopy in his Sopwith Camel
In World War 2, England was still on top. The enemies were mostly the same, with Germany as the main, but Italy was Axis, as was Japan. France, who had been the second toughest country of WWI, was now disgustingly crummy, and Canada was rapidly rising, never to drop. But despite the Hawker Hurricane, Supermarine Spitfire, Supermarine Seafire, Hawker Typhoon, Hawker Tempest, Grumman Wildcat, North American P-51 Mustang, Blackburn Skua, Bristol Beaufort, Bristol Beaufighter, Avro Lancaster, and de Havilland DH.98 Mosquito, the Germans had the Messerschmitt Bf 109 Gustav, Focke-Wulf Fw 190, Junkers Ju 87 Stuka, Junkers Ju 88, and Focke-Wulf Fw 200 Condor; the Italians had the Fiat Falco and Macchi MC.202 Folgore; and the Japanese had the Nakajima B5N Kate, Nakajima Ki.43 Oscar, Mitsubishi A6M Zero, Mitsubishi G4M Betty, Kawanishi N1K1-J George, and Kawasaki Ki-45 Nick. But in the end the workhorse Hawker Hurricane, and the greatest fighter in history, the beautiful little Supermarine Spitfire, surpassed them all.
Boeing Field’s Supermarine Spitfire.
And now, Britain still is one of the top airpowers, as the Panavia Tornado, the most radical current aircraft, has been accepted widely and is in the country category of INTERNATIONAL(as said by Robert Jackson). It could be the greatest aircraft of the coming years, currently hardly surpassed.
Have a great day!

Hello, aircraft fans!
As I have recently come home from a vacation from April 11th to the 14th, I do believe that I should write about it. I hadn’t been to Washington, D.C. in eight years. In this edition of the Plane View, (which I had a bit too much of while flying), we’ll take a look at the world’s two largest air museums: The well-known Smithsonian National Air and Space Museum on The Mall, and the Stephen F. Udvar-Hazy Museum in Chantilly, right by the Washington-Dulles airport.
The Smithsonian National Air and Space Museum is quite splendid, and it is in my top three favorite air museums. As my camera was not working well, I was only able to get a few pictures. Here’s the only one that turned out.
Me in front of the Smithsonian National Air+Space Museum.
The Stephen F. Udvar-Hazy Museum is also in my top three favorites. I do believe that I have enough pictures for this.

They have most of my favorite aircraft, including the Lockheed P-38 Lightning, North American P-51 Mustang, Curtiss P-40 Warhawk (famous by Claire Chennault’s Flying Tigers), Republic P-47 Thunderbolt, Grumman F6f Hellcat, and the Piper Cub.

We did indeed have a splendid time in D.C. My sister Katrina (www.edelweisspatterns.com) had us on the list to tour the White House, but when the tours closed, due to things like golf trips costing millions of OUR tax dollars, that of course, stopped. In the Denver International Airport at about 4:20PM on Thursday, April 11th, my sister Katrina received an email from a senator’s (not Ottawa Senators) assistant giving us the option of the Spring Garden Tour. On Saturday, April 13th, we got the tickets, and went straight to the tour at 12:30. It was most splendid, along with the Army Band.
The White House.
Speaking of the Ottawa Senators, my dad and I went to watch a Washington Capitals game against the Tampa Bay Lightning. The Capitals were ahead 3-0 at the end of Period 1, 5-2 at the end of Period 2, and 5-5 at the end of regulation. Washington won 6-5 in overtime. Yes, another glorious moment in NHL history.

Bombarding the Aircraft Industry
Hello, aircraft fans!
In this edition of the Plane View, we’ll take a look at the most popular short-range aircraft company in North America: Bombardier. Operating mainly from Canada, this company has made one of the most used short range jets (the CRJ700) and one of the best turboprop airliners available (being the Dash-8). It also has created a fine firefighter aircraft.
The Dash-8 has worked beautifully for Horizon, Air Canada, and Alaska.
Back in 1965, Bombardier, along with De Havilland Canada, formed a plan to create a turboprop airliner. They did so, and the result was the Dash-7. It was indeed a major progressive step towards the Dash-8.
Meanwhile, Bombardier teamed up with Canadair design the CL-215/CL-415. Firefighting has always been its main role, and has been used by a number of operators in North America and Europe. It has been used since 1967, which was important as the Grumman G-21 Goose and Consolidated PBY Catalina had both become obsolete.
Again with Canadair, Bombardier created the CL-600 Challenger. It turned out to be a whole series of aircraft, but it had such a small load of only 19 passengers that it was not much more successful than the aircraft that it countered: the LearStar 600. Since 1978, it has not had as many sales, but is indeed a superior aircraft.
By 1983, the 1965 Dash-7 was rather obsolete, so Bombardier again teamed with De Havilland Canada to create the Dash-8. It has been extremely successful, and would have been even more so if the regional jet had been preferred over the regional turboprop. Over 600 have been sold, and the main users are Alaska, Horizon, and Air Canada.
A Horizon Dash-8 flying in for a landing.
In 1991, Bombardier and Canadair joined to make their most famous aircraft: the CRJ. The entire series has “bombarded” (get it?) the regional jet market. Airlines such as Alaska and Horizon have found it just perfect for regional flights, and the Boeings have put away for the long flights. But a few Boeings still remain in the regional service.
And now, one of Bombardier’s greatest feats: the BD-700 Global Express. Yes, the name is very fitting, as this aircraft can fly at 678 M.P.H. for 7,485 miles with 8 passengers at up to 51,000 feet. It can still fly with up to 19 passengers, but with a shorter range. It was designed to create a new meaning to speed, range, and comfort while on aircraft flights. It is capable of the New York to Tokyo run. And over 70 have been sold already.
Another variant of the Dash-8.
The aircraft mentioned are Bombardier’s most successful airplanes. I’m also glad to hear that the Boeing 787 Dreamliners were grounded.
Have a great day!
Isaiah
