Flight Manual

I. General information

• The HAC (Havi Aerospace Corporation) F-12 Sentry is a 4+ generation single-engine supersonic multirole fighter aircraft. The aircraft is designed for multiple roles, with its primary role being air superiority, its secondary role ground attack via externally mounted pod.
• F-12 is intended for the export market, specifically for nations with limited military budgets or those seeking a cost-effective replacement for MiG-21.

  III. Flight and control system

a) HUD

• HUD is divided to 3 sections: Display, Warning Lights, Function Buttons
• Warning Lights:
  LowAlt: Low Altitude (Activated<=200m)
  Low Fuel: Low Fuel (Activated <=20%)
  LG: Activated when TAS>=400 km/h and Landing Gear isn’t retracted
• Function buttons:
  (Note: Activate 1,3,4 on HUD is not the Activate that you know)
  Activate 1: No Function
  Activate 2: Warning lights
  Activate 3: No Function
  Activate 4: No Function
  Activate 5: Targeting pod
  Activate 6: Drop external fuel tank
  Activate 7: Deploy ejection seat parachute
  Activate 8: System
  NAV: Navigation lights
  ↓: Previous Target
  ↑: Next Target

• Display:
  Displays basic flight information: TAS, Altitude, Warnings, Angle of Attack, Mach number, G-load, Heading.

  b) Multifunction Display (Left)

• The first button on right column: switch to weapons information

  c) Multifunction Display (Right)

• Right column:

• The 1st button: switch radar mode
• The 2nd button: Radar on
• The 3rd button: Zoom2x
• Bottom row (Left to right):
• The 1st button: Cycle Targeting Mode
• The 2nd button: Next target
• The 3rd button: Previous Target
• The 4th button: Next Weapon

• The 5th button: Previous Weapon

  d) Function control buttons:

• Located below Multifunction Display (Left)

• Buttons include:
• Canopy: Open/close canopy
• Parachute: Deploy aircraft parachute
• Landing Gear: Up/Down Landing Gear
• Parking: Parking
• Air Brake: Lock/Unlock Air Brake

• Warning Light: Activated when Brake isn’t released

  e) System

• Ensure all switches are turned on; otherwise, the engine won’t start up

  f) Automatic System (Important):

• The aircraft can automatically retracts the landing gear if TAS>400km/h. However, you still have to press landing gear button once more; otherwise, the elvator angle will be limited to 14 degrees, which reduce the flight performance of the aircaft, and when TAS<=400km/h, the Landing gear will automatically extend, even if you don’t intend to land.

  g) Control

• Take off (Standard configuration 4x missiles and 1x external fuel tank):

• Push throttle to 12%, gently pull the Joystick backward and maintain a Pitch Angle <= 10 degrees.
• Landing:
• TAS<=400km/h, otherwise the landing gear won’t extend.
• At the time 2 rear wheels touch the ground, Press 3 on keyboard(Activate 3) to deploy Parachute and push the joystick forward. Slightly release and apply the brakes, avoid holding them down, or the aircraft may pitch nose up.
• Supersonic Flight (TAS> Mach 1):
• To activate After Burner, press the button under the Throttle.
• Avoid aggressively Joystick inputs, as the aircraft may reach its limit and abnormally works.

• Maintain the Pitch angle approximately -+5 degrees

  h) Ejection seat

• To activate ejection seat, look down, you will see the Green button/Activate 7 for Ejection and Red button for Deploying parachute.

  i) Navigation System

• Press “Power” button to activate Navigation System.

• There are 4 locations you can choose, includng: Wright (W), Yeager (Y), Avalanche (A), Maywar (M).
• After selecting a destination, the indicator will guide you to that location, control the aircraft so that the indicator points to zero (direction 0 is the location heading).
