… the Colt boys were great at talk-downs,” Hey don’t forget those lasses; very good unflappable ATC: –
Self, turning down-wind after chute failure declaring priority, to which the response was “one on GCA, three ahead downwind; you are number four with the same priority!”

I hope nobody minds me asking a bit of a daft question, its one ive been itching to ask for years. On a very high performance aircraft such as the Lightning as you were cruising along and decided to select reheat on both engines what was the sensation like? Also what was the rate of the airspeed increase like, I suppose the word I should be using is acceleration? Thanks in advance to anybody who could put this one to bed for me.

CS Lasses, The one I can remember from 75 Was Gay Woolnough (sp?) after the Jags arrived.

Had one pilot flying the circuit in hysterics of laughter in the cockpit till he calmed down - after she made him overshoot because, quote, "She'd just had an abortion on the runway"....

Courtney Mil Bevo,

Yes the Colt boys were great at talk-downs, but I would say the service we had at all the FJ stations was excellent.
I don't doubt it. Just that Coltshall was the closest divert base with Lightnings. :)

:8 time.

Ref that video of the low flier attacking the camera; did it have missiles on the upper wings? If so, what was the effect on lift - am I right in thinking that it would be increased?

cornish-stormrider 31st Jul 2012 06:51

want more WIWOL tales, one of best threads of evah!!!!

VFR above - I presume that translates into engineerspeak as f*****g high up...

tartare 31st Jul 2012 07:00

Aside from the overwing and ventral tanks - did they ever consider any kind of conformal dorsal or spine tanks to increase range?
Maybe there were area rule implications...

Fuel tanks. Peeled off upwards and backwards if jettisoned. Limited max speed and G limit.

Al R 31st Jul 2012 07:22

Cheers. I don't want to sound like a spotter, but if the tanks disrupted and slowed down (?) airflow over the wing topside, would that increase lift, getting you to altitude more efficiently? Why were they used if they chopped top speed (useful for an interceptor) - were they used if CAP was necessary if tension was heightened/loitering required? Was the Lightning ever used to loiter - what was the longest sortie and was it any good at it (it must have required frequent topping up?) or would the Phantom have been used for that instead?

(geek, I know)

Also they could carry 1000lb retarded bombs, seem to remember the company I worked for being involved in the release trials for I think the Saudi's

tartare, they did put fuel in the flaps of the later marks.

Lightning weapons loads
 
Amongst my treasured souvenirs is a brochure on the Lightning that I picked up at Farnborough in 1968. In it they show pairs of Matra combined rocket / fuel pods on each wing pylon. This version also had outer wing pylons outboard of the wheel wells. Thei could carry a pair of SNEB pods or 1,000 pound persuader.

All in all, the export jet could carry a heap of goodies, yet the only accessories the RAF ones had were the over wing tanks. Surely WIWOL chums would have welcomed a pair of AIM-9's on the outer points?

You can take most of the ground display weapon loads seen at Farnborough, and other similar gatherings, with a very large pinch of salt. Choose just a few from the range displayed and that might be a possible flight configuration. Apart from the total mass to be lifted and the levels of drag induced the release characteristics of weapons require stringent limitations to be applied that invariably limit what else can be carried alongside.

Initially, there was an intention to field an Air-to-Air 2" Rocket Pack for Lightnings, interchangeable with the Missile Pack, this was quickly dropped following 'exciting' flight trials!

Everyone understood that jettisoning the 'Overburgers' with fuel inside would possibly break the wings. Hence, the limitation to jettison only when empty. Allegedly, a ground trial at Warton jettisoning Full Over-Wing Tanks broke both wing spars and then the Tanks just fell off. Not sure what drove anyone to try this without the benefit of aerodynamic separation, almost a bound to happen scenario!

The Overburgers were rarely fitted, being confined to long distance ferry sorties, eg UK to Singapore or similar.

Not quite true. The LTF had the AFS (Airfix Special), which was a T5 fitted with the large ventral, over wing tanks and a fresnel lens in place of the radar to increase radar size. They flew it as a target and it would stay up long enough for 2 consecutive student sorties in F6 against it.

Sorry, I was unaware of such a beast. It was not around during my periods with the force. All that time in a Tub flying target profiles, deep joy http://images.ibsrv.net/ibsrv/res/sr...ies/wbored.gif

Possibly a little entertaining following an engine failure after Vstop on a warm day?

Some Lightning Squadron Commanders would have loved such a toy, the Chinagraph Line would have been pushed exponential!

BOAC 31st Jul 2012 17:16

Not long after my arrival on 23(F) I, as JP, was detailed to go punch some holes in the midnight sky for the 'chinagraph line' with O/W tanks on a Mk6. I elected, for fun, to file airways and entered at Manchester northbound using only offset Tacan to navigate. Much hilarity from ATC as they enquired whether I needed vectors to remain in the airway.:)

Those O/Ws were BORING! I seem to recall 2.5g limit until empty and your lookout went for a ball of chalk - not that you could do much if bounced:{

safetypee 31st Jul 2012 17:56

IIRC most of the stores/configs listed were flow by, or in support of the overseas programs.
One of the exciting flight trials of the 2” rockets was in a T5 when the open nose-doors reduced the directional stability during the rapid roll / pull out after launch. The fin departed the aircraft followed by the pilot shortly after.
I also have seen the film of the ‘twirler’, where a 2” projectile having launched, then returned to pass over the wing!

There were some early RAF development plans for fitting sidewinders on the under wing pylons, and also for a ‘Y’ nose pylon enabling a four missile fit on the nose. These did not progress beyond the Group project office as there was no money and the proposals might have conflicted with the then emergent Mk 6 gun fit.

Overwing tanks were used at Leuchars for some low level CAP trials (and low level training – for the hours), and for the air defense of the RN in UK waters. The latter task dropped the tank idea when we lost a chase and turning fight with some Buccaneers
However, for overseas deployment they did help, and I recall (that I did not notice) that the airspeed limit resulted in a relatively high Mach No during a run and break at a high altitude Middle East airfield; Boss debrief – nice run and break, but don’t do it again.

Canadian Break 31st Jul 2012 18:31

IIRC part of the issue in putting anything other than Firestreak/Redtop on the beast was the missile cooling (ammonia?). In terms of spectacles, C2 and P2 coming through the aeriel farm at Akrotiri when the final two APC Lightnings there were replaced by the F4s from Germany (92Sqn?) after Op El Dorado Canyon in 1986. Left F4s rocking on their undercarriage and bodies hurling themselves off the wings. Other interesting stories about this det available in plain brown envelopes!!!:E

I suppose that makes the F1A a 'later' mark. The tins of PRC used to seal the tanks had a very short shelf life, but time-expired tins were very useful for all manner of car (and glider) maintenance................

The forum was getting a bit dull in some areas, but this thread is getting really good. Don't hold back, guys. Keep it coming. :ok:
