@Munir, One can understand and to an extent agree on the C-130 and F-27 crashes but the F-16 incident is bewildering at best, i mean who would have Zardari used to execute that accident.... surely not the Americans. !!

It was not an F16 that crashed. The Cessna's fuel was not what it should be... It crashed after getting airborne and luckily the pilot survived but he had to get his leg amputated. The man is an example of being pure (not being tempted or forced to corrupt) and a top pilot. The only one legged F16 pilot in the world. I can tell you what happened after that but let us be clear... You all voted for a criminal to be the first president to rob your nation for 4 years. This man should have been hanging or even better... shot.

I know Usman. I read enough of Tufail but this comment is simplistic. Certainly of 45 minutes per sortie based on averages... I expected more technical knowledge.

1. About Sir Kaiser Tufail's observation of 10,000 hrs and 13,500 sorties to calculate 45 min flight time for JF-17: There must be some spread in the distribution of flight times. Without knowing other statistical parameters, it is pretty difficult to base a guess upon simply the average. I can guess that some of those flights could be no more than half an hour. Conversely some flights might be more than an hour. It is fairly hard to tell exactly how long the plane could sustain itself in clean configuration and in one external fuel tank configuration. Another unknown would be the number of sorties with three external fuel tanks and the resulting skewing of the average, but AVM Javed Ahmad has said that most of the sorties have taken place in clean configuration or with just one external tank. I would like to think that AVM is correct in saying that it has enough fuel for tactical missions and required on-station time.

2. About AESA, we have always had a pretty strong guess that Block III would have AESA. It is good to get a confirmation about the plan.

3. Can someone say which locally produced weapons are being integrated on JF-17?

4. Conformal fuel tanks would impact the agility and maneuverability as well as increase drag. Perhaps it would be pertinent to have some planes adopt this and not have all of them go through an upgrade.

5. I have found nothing about a possible increase of hard points. Perhaps PAF does not wish to disclose any such plans. It is good to know that dual ejector racks for missiles are under evaluation. My guess is that having extra hard points is more important than conformal fuel tanks, since, in conjunction with a higher thrust engine, we can have both range and payload.

6. Third squadron is again delayed til the later towards the end of the year. It would likely have aircraft with Block II specifications (both new builds and upgraded Block Is).

I do not think that it is the Chinese weapons that we got with TOT and Pakistani names... I personally think that Ra'ad will be part of block 2. Just like small diameter guided bombs. There are some very very interesting concepts from the past which I have not heard some time...
 
. . .
@Munir what else we can expect for JF-17 from Russia and what Pakistan may be able to get other then Mi-35s as you said they are tiny stuff as compared to what is being tested.
 
. .
I am sorry. You just have to wait.

Can we get Su-35s through China or Russia will remain silent and let China sell sino flanker with Russian system to us?

There was another one legged pilot in the PAF, Dotani, if I'm not mistaken?

Range is dependant on the quantity of fuel not thrust.

Since Tufail is a well known pilot, let him tell how long F16 flies without fuel tanks...

I think I have not explained my point very well. What I meant is that if we are able to get a higher thrust engine, then we can afford to put at least two extra hard points on wings. That way JF-17 can take off with three fuel tanks as well as desired weapon load (for A2A at least). Hence JF-17 can have greater range with a higher thrust engine. Please note that I am making a connection between Thrust and quantity of fuel and then range given extra hard points.

PS> Another way of improving range would be to have an improved version of EJ-200. That would save weight, volume, and give a much improved fuel consumption. That would automatically mean better range from same air-frame.

JF-17 Developments Indicate Aircraft Is Still On Track

ISLAMABAD — Contrary to speculation, development of the JF-17 aircraft continues apace with avionics and weapons carriage capability improvements, work ongoing on future variants, and impending establishment of the third squadron.

Chief Project Director of the JF-17 program, Air Vice Marshal Javed Ahmed, told Defense News the program was “as per schedule and there are no delays,” saying the current fleet had logged 10,000 hours and flown over 13,500 sorties.

He also revealed the third squadron would be raised after Exercise High Mark 2014 toward the end of the year.

Chief among these improvements are avionics, with Ahmed highlighting they are aimed at improving “situational awareness” and the “performance and lethality of the aircraft,” but still centered on the NRIET KLJ-7 radar which supports the SD-10 beyond-visual-range air-to-air missile.

However, building on local capability, “integrating some additional smart and indigenously developed weapons” is underway, though Ahmed did not specify.

Short-range air-to-air armament, however, still consists of the PL-5E II, a recent variant of an aged weapon.

Nevertheless, analyst and former Air Commodore Kaiser Tufail says the Air Force is happy with Chinese missiles.

“Price per unit seems to be a likely factor, besides hooking them to the fire control computer for firing zone solutions, which would also cost a fortune,” he said.

Potential payload shortcomings have also been highlighted by analysts. The JF-17 is often seen with three large drop-tanks indicating low internal fuel capacity and/or high consumption by the Klimov RD-93 engine.

However, Ahmed says the three-tank configuration is for ferry flights or “extended operational training exercises/missions” with routine flights made “in clean or single-tank configuration.”

Therefore, for smaller nations and those conducting tactical missions, “it has the requisite reach to engage targets and can also provide required on-station time in an air defense role,” and aerial refueling “further augmented reach and endurance.”

Tufail is unconvinced, though, and highlights that 10,000 hours/13,500 sorties, equates to 45 minutes per sortie.

“Notwithstanding the aerial refueling capability [which has many operational and logistics limitations], the short sortie time may be a no-no for prospective buyers,” he said.

His most likely solution is not so straightforward, however.

“[Conformal fuel tanks] are absolutely essential to a multi-role JF-17, but these are not easy to install, since the aerodynamics of the aircraft is greatly altered and it would call for flight testing in all regimes, including certification of all stores anew.”

Ahmed says other solutions are being considered “based on customer requirements.”

“The dual rack ejector for bombs has already been integrated, flight tested and being flown in PAF. A similar concept of multimissile launcher is under evaluation for missiles,” he said.

Though largely operated by state-owned and Air Force-run Pakistan Aeronautical Complex, Ahmed also highlighted progress on increasing private sector involvement.

“Several Pakistani vendors have been cultivated and brought up to the proficiency levels mandated by aviation programs. The nascent aviation industry in the private sector is taking root and is gradually enhancing its share in this program of national importance,” he said.

Though numerous analysts have commented on the lack of export sales despite well-publicized promotion and apparent interest from potential customers, Ahmed defends this apparent lack of success.

“Defense purchases, especially those of combat aircraft, are expensive undertakings and are therefore preceded by lengthy evaluations and detailed deliberations by the professional decision makers. The response that the aircraft is receiving is highly encouraging and the export orders may not be far off,” he said.

He also stressed that the JF-17 was still a highly attractive option in an age of austerity as it “offers a highly cost effective solution with cutting edge capabilities,” and that “no other contemporary combat aircraft offers the same capabilities in comparable price range.”

Ahmed also highlighted customized “avionics and weapon packages according to the specific requirements of each customer” as well as training, maintenance and logistics packages, which includes “indigenously developed customized solutions, testers and simulators.”

Ahmed did not, however, shed any light on reports the JF-17 could be offered in a wider package including the Chinese ZDK-03 AEW&C aircraft.

Looking forward, Ahmed confirmed aspects of the Block III avionics package, which would include the evaluation of an active electronically scanned array radar option along with other upgrades, and this process was also mindful of potential export customer requirements.

“At present, the Chinese and indigenous systems are performing well in JF-17 aircraft. However, there are different Western proposals and considerations for avionics systems of Block-III JF-17 aircraft which could also be an option for our customer countries,” he said.

Analyst Usman Shabbir of the Pakistan Military Consortium think tank is unsure this will occur, but believes a “domestically produced engine may in the end tilt the balance towards a Chinese purchase.”

“They certainly have lots of units to replace,” he says.

Nevertheless, Shabbir said everything laid out by Ahmed “shows a well thought out road map for future variants and the capability they would provide.” ■
