As far as I know A-5s never carried any worthwhile sensors, no laser bombing capability, and no specialist weapons. It was only useful in day time rocketing and bombing. And yes i stand by my FACT!
It NEVER had a radar...a radar is somethin that emitts radio waves n then recieves em back...processes that info for sum purpose...all it had is whats an attack computer and even that was disabled later....so basically its pilots had to do manual bombing....its much much harder then a mirage or F-16 coz all u have to rely on are ur own parameters, thers no HUD to assist u, just a manual cross-bar sight.
That is what iam referring to. Unlike the F-6 it had the capability to assist itself in bombing and target aquistion. Since F-6s were even told where to bomb via control towers.
The pylons u saw were just pylons. They are hard points, they can be fitted with papas OR rocket pods OR practice bomb pods. Dude believe me when i tell u thers no more rocketing in PAF ok 
Alright since you claim to have flown one, Ill take your word to be authentic enought.
u call 5000 litres a limited radius? This bird ferries from Pesh to Karachi without a refuelling....limited? r u ok? F-7s n PGs CANT do that. n the thing about mirage n F-16 being better...F-16 was born better but the mirage was getting constant upgrades....rose, then rose 2 and 3...it has a NAS, a FLIR, some with even an AI...cudnt they have given the A5 an AI and a HUD or NAS.....The nose of the A-5 is as empty as the day it arrived in Pakistan...cudnt they have fitted anything in there? not even a HUD?
Iam sorry but the range you are referring to is highly incorrect. Its combat radius was hardly 500km. Range primarily means combat radius. After all, in war one has to return to its homebase too. As for Mirage getting constant upgrades, yes because Mirages are far more capable then A-5 due to their PERFORMANCE. They are supersonic, have more hardpoints and have much better service cealing. Last but not the least, the take off weight of Mirages is more then the A-5. Even the combat radius of Mirage is greater then that of A-5.
As for F-7s, oh please! F-7PGs FERRY RANGE is above 2000km and its combat radius is above 800km and these figures are FAR more greater then that of A-5.
You really are a pilot? :S
If A-5s destiny didnot included upgrades then it is bound to be called INFERIOR to Mirages and F-7s. Infact till yesterday, it was the most inferior combat aircraft in our inventory.
Headache???? What head ache my dear? The crashes? do u know how many F-7s or Mirages have crashed in the past? no u dont.....crash rate is always there on every weapon system and an aircraft will only be as reliable as its maintainers...if u dont maintain it well then dont expect much from it.
I never mentioned about crashes. Even if you compare their crashes, do you mind pondering on the total number of Mirages and A-5s crash rate vis-a-vis their total number in PAF?
n ur last statement was the biggest laugh....a mirage performs better A2A n A2G...so my dear how did u say this? do u want me to relate both aircraft turn radius? dont u know which wing design turns better? a sweep back or a delta? the only edge it has in A2A is acceleration n thats of no use except to extricate, that means its a defensive edge not an offensive edge. In A2G both had similar results always except for when the rose upgrades were introduced on mirages. similar upgrades cud have been introduced on the A-5 as well so thats our own fault. Even then A-5 always brought very good A2G results despite its limitations, e.g my own best score of 10 DH out of 12 in a single day in a single exercise, n thats a squadron record too.
Lolz, so you mean if Mirages have a poor turn radius then they are not efficient "bombers/attackers"? Really? And I thought one needs sensors, targetting pods, etc to deliver the weapons efficiently.
And frankly, I have never seen an A-5 firing anything other then rockets, 23mm guns and free fall bombs. I wonder from where did your managed to drop LGBs that too from without the help of ground forces.
Do you mind mentioning the name of infra-red sensors currently equipped on the A-5?
To cut everything short, state ONE ROLE of A-5s which Mirages or F-7s cannot perform efficienty? If I start telling you about the roles which A-5 cannot perform vis-a-vis Mirage, then there is a long list.
Not to mention, the Mirages currently perform EVERY A2G role in PAF. From close air support to stargetic attack. Meddle assesment to anti ship warfare. A-5s donnot even stand close to the worth of Mirages in PAF as for now.
And here we're not even discussing the overall maintaines cost of those two huge turbofans. 
P.S
Its overall performance is roughly equivalent to that of the British 105D and the French TMV of the 1980s. [FACT]
