Pilots of the Sherdils are not dedicated aerobatics pilots, and are drawn from jet flying instructors at the PAF Academy's Advanced Jet Training Squadron having the primary responsibility of imparting basic and advanced jet training to cadets & young fighter pilots. The Sherdils prepare and conduct formation aerobatics at various national and international events.

History

Sherdils over Islamabad

The team was officially formed on 17 August 1972 on T-37 aircraft as a result of efforts by an academy instructor, Sqn Ldr Bahar-ul-haq. The team was inspired by the Red Pelicans, the aerobatics team of RAF College, Cranwell where Bahar had been on an exchange tour. It was decided to put up a brief show on graduation parades as a demonstration of the professional skills of academy instructors. After several trials of candidate instructors, a team was formed under the command of Wg Cdr Imtiaz Bhatti. He was the Officer Commanding of the BFT wing at that time. Other formation members included Flt Lt Aamer Ali Sharieff, Flt Lt A Rahim Yusufzai and Flt Lt Niaz Nabi.

1974 - 2004 (Four-Ship T-37 aircraft) - The initial performances of the team were highly successful. The "Tweety birds" performed at air shows for foreign dignitaries, including heads of state and military officers. Initially, the team had no name. The personal call sign of the leaders also denoted the team; it flew as ‘Sherdils’ for the first time on 19 September 1974. Since the team's inception, type of Sherdil Formation Aerobatics Display essentially remained the same (even with K-8Ps till 2017) – line astern to the diamond formation during a loop, then clover-leaf, steep turn, barrel roll and finally, the bomb-burst. Attempts were made to increase the number of aircraft in the team, but engine thrust demands were excessive for the outer formation members to cope with. A four aircraft diamond has thus remained the basic formation of the Sherdils for almost three decades.

2004 (6-Ship T-37 aircraft) - In 2004, the number of aircraft in the main formation were increased to six under the leadership of Wg Cdr Tariq Chaudhary, OC BFT Wing.

2004 (9-Ship T-37 aircraft): The team was further increased to 9-ship on 2 October 2004 under the leadership of Wg Cdr Vaqar Ali Qureshi, OC No. 1 BFT Sqn. This was a historical milestone for PAF as it brought international fame and respect among the community of nations. Despite the limited power of T-37 aircraft engines to handle such a big formation, especially the outer wings, it was a daunting task. The problem was catered to by the instructors of Basic Flying Training Wing flying in the team. The pioneer 9 Ship Sherdils team members were Wg Cdr Vaqar (Ldr), Flt Lt Armughan (No 2), Flt Lt Nusrat (No 3), Sqn Ldr Tariq Azeem (No 4 slot/deputy ldr), Sqn Ldr Nasir (No 5), Sqn Ldr Sohail (No 6), Sqn Ldr Zahid (No 7), Flt Lt Hammad (No 8), and Sqn Ldr Tanveer (No 9).

The only accident which T-37 Sherdils team ever met in their performance was in October 1978, losing one aircraft and its leader Flt Lt Alamdar. Other formation members at the time were Flt Lt Shahid Nisar (No 2 & Deputy Lead), Flt Lt Irfan Masum (No 3) and Flt Lt Tasneem (No 4 slot).

2009 (4-Ship K-8P aircraft) - In 2009, Sherdils transitioned from the T-37s to the K-8P aircraft (jointly developed by Pakistan and China). A four-ship K-8P aircraft performed for the first time in November 2009 at PAF Academy Risalpur. The members of Sherdils on K-8P aircraft were Squadron Leader Amir Misbah (Leader), No.2 Squadron Leader Nasir Zia (Right Wing), No.3 Squadron Leader Wajahat Syed (Left Wing) and No.4 Squadron Leader Khalid Matin (Slot Member).

2010 (9-Ship K-8P aircraft) - By the Springs of 2010, Sherdils transitioned from 4-ship to 7-ship and perform an Air Display at the closing ceremony of Exercise High-Mark 2010 at Thal under the leadership of Wing Commander Syed Ali Zaidi. Soon after, the number of aircraft increased to 9 and the team performed at the Graduation ceremony in May 2010. In October 2010, led by Squadron Leader Khalid Matin, 9-ship Sherdils performed air display at a Graduation ceremony at Risalpur again.

On 16 November 2010, the Sherdils team performed during the 8th China International Aviation & Aerospace Exhibition in Zhuhai, Guangdong, China.

In 2011, team prepared for Turkish Air Show at Izmir but the plan was cancelled at the time of departure from Risalpur. Since then, Sherdil Aerobatics Team (using K-8P Jets) has been performing Air Displays at every Graduation Ceremony of PAF Academy Risalpur, 23rd March Pakistan Day Parades, various 14th August Pakistan's Independence Day celebrations at Sea-View Karachi and regularly participates in national and international events.

Sherdil Team Modernization

2017 till date (New Livery and Aerobatics Sequence) - In 2017, under Wing Commander Khalid Matin (Officer Commanding AJTS) a new livery of Sherdils aircraft was introduced while some significant improvements in smoke appearance and persistence were also made. Overall appearance of Sherdil Air Displays was enhanced by adding amalgamation of commentary and music for the audience. To improve the aesthetics of Sherdil Aerobatics Display sequence, a newly choreographed and designed Aerobatics display sequence was adopted with addition of more thrilling manoeuvres and sequential smoke management techniques.

The New sequence of Sherdil Aerobatics Display is as follows:-

1. A 9-ship fly-by in "Spirit Formation".
2. Initial run-in by 9-ship approaching from the front of the audience followed by a 7-Ship Loop and a 2-ship "Shaheen Break" by No.8 & 9.
3. After completing loop, 7-ship conducts a Linear Bomb-Burst and spread out in multitudes of directions while crossing over audience.
4. 7g steep-turn by No.9 followed by a continuous Aileron Rolls pass by No.8.
5. 6-Ship Barrel-Roll in Arrow-Head Formation.
6. Tail-Slide by No.7
7. Twister Pass by 5-Ship with 6th aircraft performing Twisters around rest 5.
8. 3-Ship "Shaheen Break" by No.7, 8 & 9.
9. Air Display ends by a 6-Ship Formation Loop followed by vertically downwards Bomb-Burst vertically downwards to exit the venue in 6-different directions.

Sherdils Aircraft Paint Scheme - Appreciating the important quality affecting display aircraft i.e., appearance, the T-37s were painted all red. However, maintenance of the red-painted aircraft without the costly polyurethane coating became a problem. The team reverted to the all-metal finish, with only the nose, wing tips and tail painted day-glow orange. In 1980 six ex-USAF T-37s, which were polyurethane-coated all white were added to the fleet. The ‘sunburst’ paint scheme was adopted with red rays on an all-white background. Later, the aircraft were again painted red, but with the rays in white. Like T-37s, K-8P jets were also painted in the overall white colour scheme with red and blue stripes.

Experimental Livery - On 14 August 2017, the team publicly revealed a new livery of Sherdil jets (designed by Wg Cdr Khalid Matin) at an Air Display held at Islamabad on the country's 70th Independence day celebrations of Pakistan. It was an all-white fuselage with green stripe on upper fuselage running from nose to tail, culminating into an all-green vertical stabilizer having a large crescent and star on the tail. Owing to aerobatics nature and often rolling manoeuvres / inverted passes, a large crescent and star was painted on the underside of aircraft as well.

New Livery for Sherdil Jets - The livery of upper side of Sherdil's jets was retained (white, blue & red stripes) while the new pattern was applied only on under-side of jets. This livery continues till today.
