HOW TO LAND A STEARMAN BY THE SEAT OF YOUR PANTS

Leave a reply

Fully Restored AAC PT-17 Stearman

In this age of “Fly-by-Wire,” it seems almost reactionary to go back in time when we learned to fly by the “seat of our pants.”  The fearless pioneers of the First Aero Squadron certainly were accomplished at that fine art of flying by feel and sight, particularly since they had next to no instruments inside their open air cockpits to help them out.  As it was often well put for many years after they came back from the “Great War to End all Wars” (WWI), “Flying was an art that requires a keen sense of spacial orientation, feel and sight.”

That’s how your Webmaster learned to fly in 1944, but more on that in a later post.  Although I sometimes used a Stearman to fly aerobatics back then, I much preferred the much rarer biplane, the Waco UPF-7 (see below), which was both easier to land and far more maneuverable in the air.

Brand new Waco YMF-5 (UPF-7)

The Waco is so beautiful a classic of that bygone era, that they have been reproducing brand new Wacos now for years.  Although not tagged the UPF-7, they are just a later version, which looks the same. The new designation is Waco YMF-5. They are being manufactured in Battle Creek, MI.  Take a peek at their impressive website right here.

Not let’s get into the official US NAVAL Training film, entitled “Military Flight Training – PRIMARY FLIGHT TRAINING – LANDINGS”  . . . or HOW TO LAND A STEARMAN.  This film is 13:03 long.  CLICK ON THE VIDEO PHOTO TO START IT GOING . . . AND ON THE LOWER RIGHT CORNER’S ‘OPEN-TO-FULL-SIZE’ TO ENJOY IT IN FULL SCALE.

Below is another US Navy Flight Training film from 1945 with the indomitable Stearman once again its central figure. This last film is longer, 34:47 minutes.  Most of those Navy Stearmans were painted a bright yellow from propeller to tail, and wing tip to wing tip.

This bright color was not just practical, insofar as it made them easier to see when airborne, but it also led them to be given the nickname of the “YELLOW PERIL!”  To start them, a ground crew had to stand on the lower wing and energetically crank (just like many automobile of the day – which had hand cranks for starting) the Inertial Starter until the flywheel came up to enough speed to turn over the big radial 225 HP engine.

At the airport at which I worked, which was only miles from Glenview Naval Air Station (NAS), I was often saddled with that task of cranking the Stearman’s Inertial Starter.  A lot of healthy exercise.  Often, on their first solo flight, the new Navy pilots would land at our civilian airport to grab a cup of coffee at our restaurant.  Although the Navy frowned on this practice, the happy new aviators couldn’t seem to pass up the opportunity to have some extra fun . . . and good hot cup of “Java.”

After WWII, these ships were widely sold across the country, mostly for use as crop dusters, but many went into civilian hands in General Aviation, much as did the Jenny’s of WWI.  Most every Air Show had at least one Stearman with a Twin Wasp 450 HP engine hanging up front to give extraordinarily capabilities at aerobatics.  Crop dusters across the globe still use this WWII biplane as their principal aerial applicator.  Here below is some interesting data on the various models of this classic Military Training Biplane.

Stearman 75 (or X75) Evaluated by the U.S. Army as a primary trainer, the X75L3 became the PT-13 prototype. Variants of the 75 formed the PT-17 family.

Stearman 76 Export trainer and armed versions of the 75

Stearman 90 and 91 (or X90 ano X91) productionized metal-frame version, became the XBT-17

Stearman XPT-943 The X70 evaluated at Wright Field

 

THE F-22 RAPTOR – – – WATCH IT DO THE UNIMAGINABLE!

Leave a reply

Thanks to Tuan Tamvan and his YouTube series, we get the opportunity to watch the incredible F-22 Raptor do things heretofore unimaginable.  Prior to this fighter’s entry into the new 5th Generation class of air weapons, the faster the fighter, the less maneuverable it was.  But this new machine turned those old rules of combat expectations on their ears.  And it is not just fast, but it can cruise supersonically without the use of its afterburner!  It can fly straight up and then hang there as though a helicopter, then choose to slide backward and yet still controllably maneuver while in that “slide.”

But enough chatter, it’s time to see this all for yourself.

Don’t forget to keep your speakers turned on and to use this video’s hi-res imagery at your full-screen setting.  Tuan’s video is only about 11:00 minutes long.

Irene’s Awesome Russian Yak-52 Trainer Flight over Australia

Hunter Valley NSW Australia

Pilot Jamie Riddell

Make sure your sound is on, but know that there will nevertheless be little if any sound at the outset, but when Jamie connects the intercom, then you’ll hear them talking just fine, as they converse throughout the flight adventure.

When young Irene and the pilot speak to one another, you won’t want to miss the chatter.  It’s priceless, and the video gives an awesome insight into a young girl’s first great airborne adventure above Australia.  While you will hear the pilot and his passenger’s chatter, you will not hear any loud engine nor wind noise, since the hook up prevented those other sounds from being a significant part of the finished video.

You will watch as this young lady has an experience she’s not likely to forget, and it’s written all over her face as she is cavorted above the airfield at which the Yak is based.  Notice, on take off, what a good rate of climb this trainer possesses.

The Yak is a post WWII 1970s vintage aircraft, designed, built and used in the USSR after the war and now available surplus almost anywhere in the world.  Much like the earlier American equivalent, the North American T6 “Texan,” except that it has a tricycle landing gear.  Of course the tricycle arrangement makes it much easier to land than its American “Texan” counterpart.  The video is 13:44 minutes long.


And, here below, is a short (3″21 minutes long) video of one of these Russian Yak 52 Trainers.  Watch as it shows off its excellent rate of climb speed, and also as it performs some extreme aerobatics after take off.

VIDEOS: Basic Training in the new T6A USAF Jet Prop Trainer

2 Replies

Thanks to our friends at FIGHTER SWEEP for this short (1:15)  video (immediately under the static photo of the plane parked on the ramp) of the new USAF & Navy T-6A Texan II Jet-prop trainer at work plying the clouds. The Raytheon Aircraft-built Texan II is a single-turbo prop engined, two-seat primary trainer, used to teach basic flying skills to Air Force and Navy pilots. 

The aircraft is fully aerobatic and features a pressurized cockpit with an anti-G system, ejection seat and an advanced avionics package with sunlight-readable liquid crystal displays, or as they are more commonly known, a full “Glass Panel.” It is the military trainer version of Raytheon’s Beech/Pilatus PC-9 Mk II.This trainer was first featured on our site some four (4) years ago.  One of its early test pilots was none other than our own FASF Advisor, Patty Wagstaff of Florida, Air Show and International Aerobatic competition fame.

And, immediately below, is another (4:15 long) video of the Texan II in action – Practicing formation and aerobatic work. The lead female pilot using the cockpit GoPro camcorder is Air Force pilot, Courtney McCallan.

And, below, another T6-Texan II training clip, 3:10 in length.

Below is another video, but this time of the original WWII – Korean Conflict Basic Air Force and Navy Trainer, the North American T6, which was designated the SNJ by the Navy.  The Canadians and British called it the “Harvard.” The Basic Trainer was conventionally powered.  This video is 5:26 in length.  This is the airplane in which your Editor did his basic training in the USAF.

Below is a 3:29 long video using another HD Go-Pro camcorder taking the cockpit view during airshow maneuvers in Germany.  Notice the control stick is the British type with a small ring at the top of the stick.  This is the kind of stick, called a “Spade Stick” found in both the Super-marine Spitfires and Hurricanes fighters that successfully fought the Germans during the Battle of Britain in WWII.

Below is the 3rd phase of flight training at Vance AFB – the class’ final video summary of their year training to be USAF Pilots.  The full video was class (student) produced. Show is 5:30 long.  Gives a good insight to what lies in store for USAF Pilot students in their first year of Pilot Training.  Includes typical student off hours recreation activities and finally the step up to flight training in the T-38 “Talon” aircraft.

Time to fly! Row of Texans at the ready.
