Thought this was interesting footage. Looks like the left hand is pretty busy working the nozzles.

Wow...awesome footage. I wonder why he shook his head after touchdown?

How do you move the actual nozzles in the Harrier? Where is the actual control located?
A lever by the throttle. Also yaw and bank at a hover are controlled through the pedals and stick.
Is it on the throttle lever itself or next to it? If it is next to it can you always reach it with your finger while the hand is on the throttle, regardless of which position the throttle lever is in? Just curious.
Well hopefully Banjo33 will chime in since he flew the things. My understanding is that's it's a seperate lever near the the throttle. At a certain down nozzle deflection eng bleed air is directed to the wing tips and tail as well.
wow! That was awesome. I saw a Harrier once at Teterboro airport as he was departing. I was hoping he'd takeoff vertically but he did a normal takeoff and zipped away like a jet
I wonder why I've never seen any at the airshows?
He probably took off in STOL to avoid damage to the runway. We had an AV-8 take off once at NBC and he turned the nozzles down a little too soon. The exhaust burned two streaks into the asphalt. Runway was out of service for a couple of days for repair.
AV-8s used to do a lot of air shows. Not sure if they're scheduled for next year though. I know the Hornet demo teams are grounded next year.
I don't think it was a STOL takeoff, looked like a long roll before he got airborne.
Yeah I've gone to many airshows here in the Northeast but I've never seen one

They always do that when they know people are watching. There is a former Marine Corps Aviator that has his own personal Harrier and he does a pretty awesome show.
I don't think I've ever seen a Harrier do a vertical landing or takeoff, outside of an airshow demo. I'm guessing that they tend to prefer flying like an airplane when in the vicinity of other fixed wing jets.....they are already annoying enough to share the pattern with just doing STOL landings, what with their 80 knot or whatever approach speed.
STOL is Short Takeoff- SOP for the AV-8. You might be confusing it with Vertical TO. Allegedly the AV-8 can of a vertical takeoff, but it needs to have zero load. Pilot and min fuel.I don't think it was a STOL takeoff, looked like a long roll before he got airborne.

Harrier pilots have to really work for it.A lever by the throttle. Also yaw and bank at a hover are controlled through the pedals and stick.

You need to come underway on the LHD! You'll see plenty of vertical landings. I've never seen a Vertical Takeoff, however.

I heard 5 mins max on hover because the water injection runs out? Also, the chain moves all 4 nozzles? Now way for any of them to malfunction and move independently from one another? Thanks.

Nauga,
with exactly two pressups in his logbook
Safety chase in the back of a TAV-8B, we had a little gas left after lead came back. Long time ago.Nice! What was the occasion?
There's a multitude of ways to takeoff and land this jet! VTO, RVTO, STOL flap STO, AUTO flap STO, CTO (conventional takeoff). VL, RVL (60 kts/5 deg approach), fixed nozzle STOL flap slow, fixed throttle STOL flap slow (throttle remains set at a fixed rpm and you manipulate glide path/AOA with nozzle deflection alone), auto flap fixed nozzle/throttle slow, CL (conventional landing).
I love the bird and talking about it, so please ask questions!
The throttle and nozzle lever are side-by-side. Both are vertically oriented, but the nozzle lever is shorter and has a ball on top (it's also located in the middle...between your thigh and the throttle). The nozzle lever is directly connected to the nozzles...via chain, not unlike a bicycle chain/gear. To rotate the nozzles down, in order to hover, you pull the nozzle lever aft. You learn EARLY in training to always be cognizant of what lever is in your hand! I can only imagine the horror of leaving the bow of the ship and pulling the throttle to idle vice putting the nozzles down for that initial boost of lift needed to augment the wing so early in flight. To accelerate forward, you slowly slide the nozzle lever forward (to point the nozzles and thrust aft). Too fast and it's called "doofing the nozzles" where you'll get a very rapid sink rate/high AOA if the wing isn't generating enough lift. You also learn to quickly pull nozzles back in if you were over-zealous in your nozzle-out technique! Lol!
It's been a while, but I seem to remember the average VL performance being around 1000-1500 lbs of fuel. Meaning with a "clean" (no weapons) jet, you could VL with a 1000 lbs of fuel. Cooler temps provided more bring-back...warmer/higher DA means less performance. Less fuel onboard would allow you to bring back more ordnance, etc. Water injection into the engine would allow a higher VL weight. I've done a vertical landing with negative VL performance in 0/0 conditions, but you'd have to buy me a beer to hear that story! Lol! We practice VTOs (vertical takeoffs) at the end of our sorties once we've burned down our gas. In reality though, if it's pre-mission and we have ordnance, we'd likely do an RVTO (rolling vertical takeoff) in which we can be airborne in a couple hundred feet with full fuel and ordnance. Not exactly vertical, but it's almost hard to tell the difference! Lol!

60 kts for an RVL and 90-120 kts for a slow landing on final. We usually fly the pattern around 120.
Thanks for the info. This confirms that I probably saw a CTO at KTEB many years ago. He rolled down the runway like any other jet and used up practically the entire length. I'm assuming that he wasn't authorized to perform a STOL takeoff at that airport, correct?
Possibly a CTO or, more likely, a STO. If it was hot, a STO would have looked much the same like a normal airplane takeoff. "Short takeoff" is a bit of a misnomer, since the airplane will likely use 2000-3000 feet of runway (maybe more depending on load out and DA). A lesson we've learned, is that no airfield is as FOD conscious as a Harrier base. FOD is a HUGE deal for us (BIG/low slung/air hungry engine, intake close to the ground, etc), so the faster we go on the ground prior to lowering the nozzles for that initial boost of lift on takeoff, then the less likely we are to toss a rock out in front of our intakes with that blast of air. It was always embarrassing to take a division (4) of jets into a civilian field. We'd darn near shut the place down when taxiing since we strictly maintained 1000 feet between jets to avoid having a jet toss a rock down another's intake!
Wow! Thanks.
So what's the average takeoff distance for a CTO? I guess it's a rare event to takeoff without lowering the nozzles.
Must be a blast to fly that thing!

What ship was that first photo taken on? That deck just looks....weird.
