F-14 Questions Answered - Ask Away



A bit of a tangent, and a little but closer to home (for me in New Zealand).

HUD tape of an RNZAF aermacchi MB-339 crew ejection. The point of interest in this one is that the back seater was non aircrew, he was a maintainer going for a flight ended up having to walk back instead of landing.

He got hurt pretty bad on the ejection (because aermacchi). The aircraft doesn't jettison the canopy or have embedded det cord to shatter it. Instead, the top of the seat has a steel "knocker" that goes through the canopy first, shattering it.

On most aircraft you can adjust the seat height, particularly in the back in order to see over the head of the front seater. In doing so the entire seat is raised or lowered on rails. In the macchi, this isn't the case. Only the seat pan raises or lowers. So when you gave a maintainer going for a flight he naturally raises the seat to get the best visibility he can. But in this case his head ended up higher than the seat knocker. Not ideal when he eventually had to eject.

I'm on my phone and not sure i have emedded it correctly so the link is also here.

If you conduct a “planned” ejection, there should be a checklist that is followed, which includes lowering the seat!

They had a lot of time from “@#$%# - we’ve got an engine vibration”, to the “Mayday” and the subsequent radio communication, to the “unable to maintain height”. Then, no prep, and “I’m ejecting, EJECT, EJECT, EJECT, NOW!”

As the engine is coming apart, I would have prepped the maintainer, by having him ensure his harness is tight, mask is tight, visor is down, kneeboard and loose gear are removed, seat is lowered, and he is sitting upright.

I’ve flown some non-aircrew in the back of the F-14. Midshipmen (that’s a great story in and of itself), senior officers, flight surgeons (lots of fun, that, because the flight surgeon was my friend and room-mate on the boat) and an Army Doctor, Major Rhonda Cornum*, who I took to the boat from Oceana.

The ejection possibility was carefully briefed, including the difference between one which we had time, and in which I expected all the above steps to be accomplished, and one in which we didn’t have time. In the F11, if the pilot pulled the handle, both seats were going regardless. But there was a command eject lever in the rear cockpit. If it was aft, in “MCO“ then both seats would go if the RIO pulled the handle. If it was forward, in “Pilot”, then only the RIO would eject if they pulled the handle.

Mooch talks about this on his YouTube channel -



Mooch gets the “MCO” acronym wrong, by the way. It meant “missile control officer” - which was the original designation fo the RIO. But Mooch is a RIO, and RIOs think of themselves as “Mission Commanders” and he has re-imagined the meaning of the acronym.

Back on topic - So, when flying non-air crew, I always made certain that command eject handle was forward, in pilot. Just in case the person panicked, we would lose the canopy, and we would lose the backseat, but we would save the airplane. But, if I knew we had to get out, we were both getting out.

What interesting about the Aermacchi, is clearly (from the communication) there is not a command eject. The ejection seats are not linked, they each fire individually.

The last communication on the tape between the pilot and the maintainer made that very clear. The pilot made sure the maintainer knew that he was going to eject, and told him to “eject eject eject NOW” - pretty clear that he was telling the maintainer to pull the handle.

And all the time that I’ve flown with non-air crew, I’ve considered this possibility quite a bit, and I thought this pilot could have done a better job getting his maintainer ready for the ejection.


*Rhonda Cornum, US Army, is now a Brigadier, retired and has both an MD and PhD. She was also a POW in the Gulf War. She was great to fly with, very sharp, and a private pilot herself. That was a great day, five traps, and then we took her Lancair flying that afternoon. https://en.wikipedia.org/wiki/Rhonda_Cornum

Pre flight procedures were amended after that flight to include steps to ensure that neither crews head was above the knocker height.

PIC was newly graduated from wings course.

If the date is when I think it was this was a brand new aircraft that had just entered service (there were "issues" with them for a while. Only aircraft I know of that ended up with a zero stage compressor). The head height issue hadn't been identified before that.

Not sure if it had anything to do with crews getting correct alignment of eyes with the HUD.


EDIT: lessons (thankfully) learned, but (unfortunately) learned the hard way.
I cant comment on the ability to command the ejection sequency sorry, as I dont know how that worked for this aircraft.

Also on another tangent but RNZAF related, we lost several A4K Skyhawks (three I think) on my first year of joining, it was a pretty morose time. If anybody has interest on the A4K (NZ was the only country to operate this configuration of skyhawk) there is some public domain information available such as here https://en.wikipedia.org/wiki/Project_Kahu

Basically, an A4G with the avionics hump removed (makes them faster), zero time wings installed, and F16 avionics fitted (APG-66 radar etc). It made for a significant upgrade in performance on a budget, but they were definitely dated when retired. I think the Israeli skyhawks had a slightly more powerful engine while the RNZAF had some of the best avionics fit out of the world skyhawk fleet. RNZAF A4's are now being flown by Draken

I have a few hundred hours in the A4, though it was all in the TA-4J, which I flew both under instruction, and solo. Wonderful airplane. Very responsive on the flight controls, easy to fly and easy to fly well.

Upgrading the airplane made sense for a small country in the limited budget. You get a lot of good performance, even if you don’t need supersonic capability.

I wasn’t aware that many of them had crashed.
 
I was always amazed that the long splndly nose gear on the A4 could handle being slammed onto the deck of a carrier.
Those long spindly landing gear on the A-4 are the genesis of the semi-derisive nickname "Tinkertoy." (Those of us that loved the airplane universally called it the Scooter.) Those tall landing gear were necessary, though. If you recall the size of nuclear weapons at the time the A-4 was designed (early '50s), the gear were required to be that tall simply to allow a weapon on the loading cart to fit underneath the airplane.
 
I was always amazed that the long spindly nose gear on the A4 could handle being slammed onto the deck of a carrier.
To your point, I just had to dig up this photo:

Yes, that's me and yes, that's the skippers airplane! I dropped the nose just prior to touchdown and broke the nose gear shear pin. The shear pin was a designed failure point to keep the nose gear from coming up through the cockpit deck in a situation like this.. The NG just folded into the wheel well. New NG door and some zinc chromate, and the airplane was back in service in a few days.

For the non-Naval members, which skipper and how can we see that it's his airplane?
The CO of VA-72 at the time (1966) was CDR Harry Southworth.

If the photo were higher resolution, his name is under the cockpit. But, more generally, aircraft are numbered in "Rocket Number" (seniority) order;

All aircraft in an individual squadron have the same first digit - 5 in this case

X00 always has the wing commander's name
X01 for the CO
X02 for the XO
and so on in seniority order
 
You guys correct me if I'm wrong, but I thought I read somewhere the A4 had one of the fastest roll rates in the inventory.

It was exceeded by only a few others. One of them being the T-38.

Thanks for including the Wiki reference for General Cornum. She's extremely impressive, to say the least. Incredible woman.

Can you share more about the flight where you were able to transport her to the ship from Oceana?

I think I found out on a Thursday, that on Saturday (June 6, 1993) I was going to fly somebody out to the boat. I got only the most simple details, brief time, aircraft, overhead time at the carrier, in the name of the person. I got told she was some kind of POW. I remembered her name because she wasn’t supposed to be flying (she was a flight surgeon, not a combatant) and got shot down when she was in the back of the helicopter. It was a pretty big news story at the time.

So, I stopped by the bookstore the next day, and bought her book. “She Went to War”, was the title, if I remember correctly. Read it that night.

I was able to find out that she was staying at the BOQ that Friday Night, and I called her. We agreed to meet at McDonald’s Saturday morning, early, for breakfast as the brief was long, and detailed, when flying aboard ship. We needed to discuss procedures, and what to do. I needed to get her gear fitted and sized by our parachute riggers, and then, I needed to get her in the jet, early, so that we could go over the systems, controls, and so that she could operate those few things that needed to work for our flight.

The airplane had not been “carrierized” so there was a bit of a delay there, which included a check on the Tailhook, nitrogen pressure, tire pressure, and a few other things. It was buno 161133. An F-14A

So, we were a bit late launching, and flew supersonic to get overhead the ship. It is considered bad form to show up late when the ship is steaming into the wind and waiting on you.

We had some radio problems, and since some of the radio controls were in the backseat, she had to switch antennas to see if it was an antenna issue, or it was an actual radio issue. I used the front seat radio to communicate with the ship, and I made all of the radio calls. Communication and a ship board environment requires precise, brief, transmissions. There is a protocol in the language. You don’t talk when somebody is “on the ball” for example.

It was a beautiful sunny day, a bit hazy, but relatively steady winds and calm seas.

We made a total of five arrested landings. I think the ship would’ve given us more, but we continued to have radio issues, and the Air Boss was getting impatient with us. Missing a radio call from the boss is also very bad form, and I think that happened a couple of times.

During carrier qualifications, the whole process of arrested landing, taxi clear, reconfigure the airplane, and hook up to the catapult, then launch, can be done in a matter of minutes, so we were busy with all those tasks, and then banging off the front end again, to turn downwind and land again.

I made certain that she locked her harness each time we came in to land, but the squadron representative, who was up in the tower with the Airboss, said that her head and upper body flew forward on each trap, so even though she said she had the harness locked, it’s pretty clear that she didn’t.

As we got our final catapult shot, to fly back to Oceana, we continued to have radio problems. I had her check the radio frequencies, and swap antennas between upper and lower, but I’m not sure that she actually got it right, because we never did resolve the problems and were unable to contact the controlling agency over the water - FACSFAC VACAPES (callsign: Giant Killer).

So, Giant Killer saw this airplane (ours) on radar and wasn’t talking to it. They knew from our flight plan who we were, but they vectored another airplane to intercept. As we were flying back to Oceana, I saw a Tomcat in a rendezvous on our right. Seamus “Flats” Flatley flying.

Flats led us back to Oceana.

We parked the jet, got out and she asked if I wanted to try flying her airplane. I don’t remember if it was a GlassAir or a Lancair, but either way, it was pretty fast. we filed a flight plan, and took off, and flew up the James River towards Richmond. Very nice handling airplane in all honesty and much faster than you would expect piston to be.

I know now about the cost of operating one of those things, and it was very generous of her to fly me around. Please let me add that she was great - very professional and polite. Very sharp. Interesting story about her combat and POW experience.

I did get her to autograph my Copy of her book at one point.

Still have that somewhere.

Thanks for taking the time to to tell that story! Enjoyed that!
 
All - I get quite a few questions on the F-14 via PM or in the threads...I flew the big fighter for 10 years, including in combat, and had 2 instructor tours in it.

I am guessing that a few other folks might be interested in the particulars of the jet, so here's the beginning of the thread...

WINGSWEEP:

The Tomcat's wings were programmed as a function of airspeed and altitude...based on the air data computer (world's first integrated circuit, by the way) and they worked automatically. The pilot could take manual control, via a button on the right throttle, and move them aft of the programmed position, but not forward. If the programmed position was aft of the pilot-selected position, they would go back to automatic mode and continue to move aft.

Moving the wings aft reduced high speed drag, moving them forward increased low speed lift. In particular, the sweep angle of 68 degrees kept the wing tips inside the supersonic shock cone of at speeds up to roughly 2.5 Mach. The airplane had a design criterion of 2.0 Mach dash speed, and it reached 2.3 Mach in development testing, so the 68 degrees sweep was conservative. There wasn't a huge change in area, and the F-14 got some lift from its wide, flat fuselage, particularly at high AOA, but there was a change in center of pressure with aft wing sweep - which resulted in a nose down change in trim as the wings moved aft.

This trim change required big horizontal tails to overcome the pitch trim change at all altitudes/speeds and keep full supersonic maneuverability. The F-111, for example, was only able to pull 2G when it was at full aft sweep and high altitude...the F-14 could pull right to its lift (or G) limit at every speed.

Speaking of speeds, I've seen 850 KIAS in level flight, over 900 KIAS in a descent...there are very few airplanes ever built that could achieve those numbers...the Hornet wouldn't have a prayer of going that fast...(sorry Hornet guys...loved that jet, but it was no speedster...).

TOP GUN "HIT THE BRAKES":

The "hit the brakes" was complete Hollywood. Sure, you could pitch-pulse the airplane (remember those big horizontal tails? They worked really well at low speed), but tactically speaking, you achieved nothing except to point the plane and slow it down...that might defeat a gunshot...it might be worthwhile...but in general, it had no tactical use...and it was certainly no "magic" move...

ENGINE STALLS AND FLAT SPINS:

As far as engine stalls – the TF-30 power plant (intended for the F-111, not a fighter) in the F-14A was prone to them, jet wash would be one cause, but throttle transients, high AOA maneuvering, missile or gun gas ingestion, particularly in combination, could cause a compressor stall. The GE F-110-400 in the F-14B/D was very stall resistant. I’ve had literally dozens of engine compressor stalls in the F-14A…I’ve lost track of all of them…

The engines were 9 feet apart, so, were one engine to stall at low speed (less than 140 KIAS), the plane would experience an uncontrolled yaw. Left unaddressed, that yaw could develop into a spin, particularly if the speed was very low and the AOA was very high. In the event of an engine stall, getting the AOA under control, and getting the throttles to idle (to eliminate the yaw) were critical action items if an engine stalled. Generally, the aircraft was controllable if those steps were taken, even if the engine had to be re-started. Every stall I’ve ever had was fixable in the air – either the engine had to be shut down and re-started or the stall cleared with throttles at idle and restoration of normal inlet air flow.

The flat spin part of the movie was realistic – we lost a lot of F-14s to flat spins. A fully-developed flat spin was considered unrecoverable…some guys were able to correct it in the incipient phase (as it developed…but it only took a second or two to develop) before it was fully developed. A fully developed flat spin resulted in 6+ G forwards in the cockpit (pinning the pilot against the instruments if he hadn’t locked his harness during the loss of control), 170 degrees per second yaw rate, and a descent rate in excess of 30,000 feet per minute…

NASA modified an F-14 to do high AOA testing and investigate the flat spin modes of the F-14 in the 70s. That airplane had a spin recovery parachute added between the tails and a hydrazine back-up hydraulic module installed to provide hydraulic power to the controls if both engines stalled (which generally happened in a fully developed spin). The clarified the above parameter for the spin…but recovery was very difficult…

After several flights, even with the special modifications, the NASA Test Pilots crashed the jet during testing…turns out they couldn’t recover from a spin any better than the fleet pilots…


So...ask away...I'll post my answers here.

Cheers,
Astro
Thanks Astro for that very detailed description. I am a big Top Gun fan (The original movie + Top Gun Maverick).
The F-14 is my favorite fighter jet. It is a truly beautiful aircraft with the 2 vertical tail fins and the 2 large engines on either side.

The F-14 Tomcat's top speed and other it's other specs seem so superior to the F-18 and newer aircraft that replaced it.

I know the newer planes can fire a missile from great distances, making dog fighting less important, but still, on the surface it seems a step backwards that the newer replacements are significantly slower. Speed is important, whether to join a dog fight to help fellow pilots, or to escape / retreat when ordered to do so when against insurmountable enemy numbers.

What is your opinion on the lower speeds of the newer aircraft, and did they retire the F-14 Tomcat too soon?
