IAF — Key Facts

🔥 IAF Motto "Nabhah Sparsham Diptam"

🔥 IAF Day Oct 8

Army Day Jan 15

Navy Day Dec 4

🔥 Vijay Diwas (1971 War Victory) Dec 16

IAF founded Oct 8, 1932

IAF Chief designation Chief of Air Staff (CAS)

✚ ADDED — HIGH YIELD

Gallantry Awards (rank order):

Wing Commander	Lt. Colonel	Commander
Group Captain	Colonel	Captain
Air Commodore	Brigadier	Commodore

⚠️ COMMON TRAP

Navy "Captain" ≠ Army "Captain" — Navy Captain = Army Colonel rank equivalent. Don't confuse ranks across services. Also: IAF has no Field Marshal equivalent permanently; "Marshal of the Air Force" is honorary only.

Important Missiles

🎯 AFCAT/CDS asks: "Astra is what type of missile?" — know TYPE + ORIGIN for every missile.

Missile	Type	Origin	Key Fact
Astra	Air-to-Air (BVR)	India	Beyond Visual Range; only Indian A2A missile
BrahMos	Supersonic Cruise	India + Russia	World's fastest cruise missile
Barak-8 (MR-SAM)	Surface-to-Air	India + Israel	Naval variant also exists
Akash	Surface-to-Air (SAM)	India	Indigenous; medium-range

Launched 1983 by Dr APJ Abdul Kalam. The 5 missiles: DANT + P
Dhruv (Nag) · Akash · Nag · Trishul · Prithvi (5 missiles of IGMDP)
BrahMos is NOT part of IGMDP — it's a separate India-Russia JV. AFCAT 🔥

Op Parakram	2001–02	India-Pak tension	Military mobilisation after Parliament attack
Op Devi Shakti	2021	Afghanistan	Evacuation after Taliban takeover
Op Ganga	2022	Ukraine	Evacuation of Indians from Ukraine

⚠️ COMMON TRAP — KARGIL WAR OPERATIONS

Op Vijay = Army | Op Safed Sagar = IAF | Op Talwar = Navy (Naval blockade during Kargil — often missed!)

🎯 JAN 2026 AFCAT PYQ — DEFENCE

Flt Lt Nirmal Jit Singh Sekhon — first & only IAF officer awarded the Param Vir Chakra (posthumous, 1971 Indo-Pak War). ⚠️ PVC is circular/bronze with 4 Vajras — NOT octagonal/silver.

02 POLITY

Critical Articles

🔥Art 14 — Equality before LawRight to Equality

🔥Art 17 — Abolition of UntouchabilityMost repeated in exams

🔥Art 19 — Freedom of Speech (incl. Press)Right to Freedom

🔥Art 21 — Protection of Life & Personal LibertyCannot suspend even in Emergency

🔥Art 32 — Right to Constitutional Remedies"Heart & Soul" — Dr. Ambedkar; direct SC access

Art 44 — Uniform Civil CodeDirective Principle (DPSP)

Art 72 — Pardon PowerPresident can pardon death sentence; Governor CANNOT

Art 123 — Ordinance making powerPresident (when Parliament not in session)

Art 324 — Election CommissionIndependent body for elections

Art 368 — Amendment of ConstitutionParliament can amend; cannot alter basic structure

✚ ADDED — WRITS (Art 32 / Art 226)

Writ	Meaning	Purpose
Habeas Corpus	"Produce the body"	Against illegal detention 🔥
Mandamus	"We command"	Directs public official to perform duty
Certiorari	"To be certified"	Quash order of lower court
Prohibition	"To forbid"	Stop lower court from exceeding jurisdiction
Quo Warranto	"By what authority"	Challenge holding of public office

Emergency Provisions

Article	Type	Ground	Key Fact
Art 352	National Emergency	War / Armed Rebellion	Declared 3 times: 1962, 1971, 1975. FRs suspended EXCEPT Art 20 & 21
Art 356	State Emergency (President's Rule)	Failure of constitutional machinery	Punjab was first state (1951)
Art 360	Financial Emergency	Threat to financial stability	NEVER declared in India so far

⚠️ CRITICAL TRAP

During National Emergency (Art 352): FRs CAN be suspended EXCEPT Art 20 (Protection in conviction) and Art 21 (Life & Liberty).
44th Amendment (1978) removed Art 19 from suspension protection too — now only 20 & 21 are fully protected.

Key Constitutional Amendments

Amendment	What it Did	Tag
42nd (1976)	Added Socialist, Secular, Integrity to Preamble; "Mini Constitution"	🔥
44th (1978)	Restored rights curtailed in Emergency; removed Art 19 suspension	COMMON
52nd (1985)	Anti-Defection Law (10th Schedule)	COMMON
61st (1989)	Voting age reduced: 21 → 18	🔥
73rd (1992)	Panchayati Raj (Rural local bodies)	🔥
74th (1992)	Urban local bodies (Municipalities)
86th (2002)	Right to Education (Art 21A)

9th Schedule: Laws protected from judicial review (1st Amendment added it)
10th Schedule: Anti-Defection (52nd Amendment)
12th Schedule: Powers of Municipalities (74th Amendment)

🎯 JAN 2026 AFCAT PYQ — POLITY

Fundamental Duties were added by the 42nd Amendment (1976) — NOT the 43rd. This is a classic trap. The 43rd Amendment (1977) actually reversed some powers of the 42nd. COMMON TRAP

Habeas Corpus = writ against illegal detention — directly appeared in PYQ as a one-word fill.

🎯 JAN 2026 AFCAT PYQ — GEOGRAPHY

Temperate Zones — regions between Tropic of Cancer & Arctic Circle (N. Hemisphere) and Tropic of Capricorn & Antarctic Circle (S. Hemisphere). Not Torrid, not Frigid.

Seamount vs Guyot — Seamount = pointed peak rising from seafloor that does NOT reach the ocean surface (3,000–4,500 m height). Guyot = flat-topped seamount (eroded). This distinction was directly asked.

🎯 JAN 2026 AFCAT PYQ — HISTORY

Rowlatt Act (1919) — authorized British to arrest & imprison any Indian WITHOUT trial. The Satyagraha against it was called in April 1919 (NOT 1917 — that was Champaran). Only Statement 1 of the PYQ was correct.

Battle of Stalingrad = World War II (1942–43) — decisive Soviet victory against Nazi Germany. A trap option was Russian Revolution.
