Towing Aircraft
 
Especially for all those engineers who want to tell us their war stories about towing aircraft!

Might keep them out of the WIWOL threads!

Harrier GR3, sheet ice Gutersloh, interesting slide across the dispersal pan. Brakes added to the fun. Towing suspended for a while...

ShyTorque 9th Feb 2014 14:38

What an interesting subject, well done! ;)

We don't use a brake man whilst towing because after rotor shutdown you can't steer and the brakes don't work due to the design of the system. So you need to chock the aircraft. Anyone inside the aircraft is just more weight to tow and would go straight to the scene of the accident....

Apparently I need to ask my engineering department and the insurers about this. ;)

These guys have got the answer ;)

Chocks Away SHELSLEY SPECIAL 1936

Navy always have a brakeman on helicopters.
 
True. And chockmen. Also always "push" the aircraft, rarely tow it. I once saw two Hunters recover into the overhead at Yeovilton. The duty runway (27) must have been invisible due to fog, which was thick up to about 40 odd feet. Strangely though you could see the tops of the church etc sticking out through it (from the air).
Incredibly the two hunters were allowed to attempt to land, simply by orienting themselves by landmarks sticking through the fog/ground mist. They then tried to land on non duty 22 and almost spanked into someone pushing a Harrier across it from the compass swing. Missed by inches, flew off to Chivenor, hopefully to change their pants.
Can still remember the pilots strangled scream on Channel1, what a ******.
I was in the caravan and saw nowt,Mlud.

Laar-parts, just before the wall came down.


Tasked to tow a Tornado out of ASF and back to Black Sector. This meant crossing the active, and in the heady cold war days that could mean quite a wait.


Anyway, get to the jet and find it has no battery, no hydraulics, but, still, we are ordered to tow it back anyway, and to make it look good, muggins has to sit pointlessly on brakes for the duration.


Canopy is closed for the tow, and we duly wait at the runway crossing for seemingly every Tornado in the world to burn up NATOs fuel stock doing circuits, needless to say the only day of baking hot sun was pouring in through the perspex, as I tried to figure out precisely what I was going to achieve if the towing pin had sheared.


I suppose ATCO would have been none the wiser as the towing team looked reasonably well complete.


Thinking about it though, not sure why we were bring such a crocked jet back to the squadron from ASF anyway.


All ended well though, and yours truly downed a few refreshing biers in the NAAFI after shift.

I remember climbing into a Harrier to do something or other when I was fresh onto them. It was raining so I slid the canopy shut without thinking. I finished the task, and then realised I didn't know how to open the canopy...this was on a dispersal where I may have been on my own for quite a while. I looked around for likely canopy opening switches and handles and eventually settled on a bit of black painted mild steel with a t handle on it. I knew where all the emergency stuff was (I had at least been briefed on that) so I squeezed my eyes shut and gave it a tug, fully expecting the wings to drop off. The canopy opened with a little click...lesson learned.

Saintsman 9th Feb 2014 15:41

Bring the aircraft back from the dispersal at end-ex, we were informed that ATC were non too happy with the speed of the towing. Apparently as we were towing past the tower, the aircraft (Phantom) was seen snaking behind the tractor...

thing 9th Feb 2014 15:48

Crikey, that must have been fast. Call for a caravan stabiliser maybe? :)

We used to tow them out of the shed and onto the line (ah, glorious pre HAS days) at an alarming rate of knots, can't remember any snaking. They were good days, a whole pan full of F4's, I think the OCU had something like 22 a/c plus there was 29 and 41 there at the time.

Dark Helmet 9th Feb 2014 16:35

Who'd have thought that this topic would produce so many replies!

So: TWCU at Honington in the winter. Lots of snow and ice and the forecast is that it will continue to snow. At about stupid o'clock in the morning we still towed twenty plus aircraft out to the flight line. It was not easy getting up the small incline. The wingtip men had chocks at the ready in case the shear pin went. Instead the tractor simply couldn't get enough traction and the whole tractor and aircraft rig starts to slide backwards towards another hangar that had closed doors. The brave wingtip guys slid and slipped their way to the mainwheels and popped in the chocks...to absolutely no effect! Everything just kept on sliding. I was either driving the tractor or I/C the tow, I can't remember but I just waited until we came to a stop or hit something solid. Luckily we came to a stop. I left the aircraft there and went to see if we would be able to stop this madness - I wasn't successful of course!

Eventually Operation Tow-Out was a complete success. Duty Auth arrives at about 08:00, looks at the weather and says 'No flying today'.
So an hour of downloading all the weapons in the snow and then Operation Tow-In could begin.

This time someone (not a liney) suggested that we should tow with a fuel bowser as they would have more traction on the snow and ice and would make it down the small incline and turn the corner into the hangar with no problem.

The trouble was that the bowser drivers were not trained to tow - they had no idea about how an aircraft behaves when it is so far behind you, nor did they appreciate how wide you had to make your turns to allow for the aircraft to always be in the centre of the taxiway.

It took just one, heartstopping, attempt for it all to be called off!

We left the aircraft on the line until we had all calmed down and later, with the aid of snow ploughs and gritters managed to get them all to bed again.

I would like to say that management learned from that experience but what do you, dear reader, think?

Being as the management were rarely out there freezing their nads off I think there is only one conclusion to be drawn. We often used to wonder what difference it would make if you took everyone out of the chain from Sengo upwards. Jets would still fly, the world would still turn.

Dark Helmet 9th Feb 2014 16:59

Yep, thing you are probably correct. I often used to think that. We would be left with: people who loved (most of the time) to fix aircraft and people who loved (most of the time) to fly aircraft!

Cornish Jack 9th Feb 2014 17:28

Sod's Law or Murphy's?? Whichever, Nicosia in the 50s, multi Hastings and Beverleys littered around the field and Bev on tow with nobody on the brakes. You KNOW what happened ... attempt to retrieve situation by throwing large chock under wheels just proved fragility of chocks!! Rampant Bev eventually found static version and demonstrated affection by burying nose deeply in tail of soulmate!! IIRC this was during the abortive Amman detachment so no harm done!!:rolleyes::E:E

RAF Bruggen new style tug arrived to replace the old wartime style items, these were the ones with the cab on them with seats in the back for handlers and a stowage outside behind that for chocks etc, worked a treat, but eventually needed maintainence, so MT lent us another new one, this had a larger full cab and could seat four behind the driver but no external stowage, off we go with Jag hooked on the back, go to turn a corner and bang, the pitot tube that on the shorter cab that would normally miss comes straight through the rear window..... Oops


RAF Bruggen TACEVAL winching a Jag into a HAS into the front location, doors shut and pilot doing verbal handover when the winch starts up dragging it into the wall, smashing the tip and dragging it along doing more damage, pilot and HAS chief hanging on steps trying to stop it as it hops the nose chocks, everyone runs to help, winch stopped and enquiry starts, winch stripped nothing found, Jag repaired, years later a guy who was in the HAS with me says, "it was me, I knocked the start button" when it happened everyone looked at Jag and rushed to it, then looked at winch buttons that were now unmanned so assumed a fault and he got away with it.

Brize, line office has just got the end of the financial year save fuel signal. looking out window boss says, there is an example, why is that Ten being towed with the APU running?. (me on brakes) Arrive back inside to be asked why I'm running the APU during towing, " so I can power the ovens to cook our Dulles burgers and hotdogs" I replied... Nothing else said :)

Back in the days when the VGS at Benson flew conventional gliders I was tasked to act as ballast in a Mk 3 Cadet being retrieved by Landrover and trailer.
For those who don't know the Air Cadets had a trailer on which a just landed glider could be mounted upon and returned to the launch point. As fixing it in place relied on a pin passed over the nose skid, ballast, ie a cadet, was required to sit in the front cockpit to offload the pin and not rip the skid off the fuselage.
On this occasion the retrieval had the combination driving down the length of the pan past all the hangars, at some speed it must be admitted.
Retrive over ops recommenced until the Boss came out wanting to know who had been involved with the retrieve as he'd just had a low flying complaint from the Deputy Captain of the Queens Flight, who had just looked out of his office window and whitnessed a glider chasing a Landrover at extreme low level.

Not towing as such, but just as funny,

Disaster relief in a quarry in Norfokk, it's winter and full of mud, we need the dumper truck we are using so some aircrew go to start it, 3 of them on the cranking handle trying to turn it over with no success, several of them take an interest and try to bump start the thing in about 3 inches of mud...
Much mirth from us, engine JT walks over, naunchantly leans on the engine and unseen by the aircrew pushes down the decompressor, then single handedly swings the thing over and off it goes... Walks off as stunned aircrew mouths wide open look on.

Towing Aircraft
 
Are fast jets susceptible to snaking when being towed then, sounds a tad strange. The nearest I've towed to one is an EMB145, but they never did it. I've towed jumbo's too.......now THAT would make an interesting snake

longer ron 9th Feb 2014 17:49

I hope Newt is keeping an eye on this thread !

Canberras with full tip tanks used to snake a little :)

Halton Brat 9th Feb 2014 17:54

Wiggins Aerodyne, RAF Little Snoring c.1922. Had to cast the anchor overboard from the underslung Observation Basket when the brakes on the Stutz Bearcat towing vehicle faded. Frightful calamity; CO's dog, which was chasing the Aerodyne & biting through the tail surfaces, was killed by well-aimed lob of anchor. No tea/coffee/biscuits interview with CO. Career limiting episode.

longer ron 9th Feb 2014 17:55

Actually the Snaking thing just reminded me how I got cleared to tow a/c...
For some random reason we had no qualified tow - ers in one day.
One of our canberras aborts take off and ends up at the wrong end of Cottysnore...we were right at t'other end :ok:
Flight Sgt says to me - If you can tow it back here without damaging it I will sign you up for towing - ok says I (thinking 'towers do not do station duties' ! LOL) - anyway I managed to get that one back ok...the 'Crunch' - 'Brakes' moment happened a few months later putting a cab in the hangar :)
