Vertical Half-Loop or Immelmann
Minimum Speed: 415 knots (fully loaded); 320 knots (no bombs)
Minimum Altitude: None
To reverse direction and bleed off excess speed or gain altitude, the Vertical Half Loop is recommended.
• You're flying straight and level (1).
• Pull back on the stick and hold (2).
• Let off the stick when you're flying upside down (3).
• Apply full left or right stick until the horizon comes around level (4).
The Vertical Half-Loop, a maneuver that gains altitude and reverses your heading, is the opposite of the Split-S.
