Range Card & Weapons Events

Post by Sharpe »

Any live weapon can be used on the range. However, use of the BDU-33 practise bomb unit offers distinct advantages for certain aspects of training. It weights 48Lbs and emits a white smoke for easy BDA. Three can be loaded on a regular TER and if you try to load more, the TER will be replaced with a SUU-20 carrier in which 6 BDU-33 can be carried. The BDU-33s are considered marking weapons and although they have the same aerodynamics as the GP Mk-82 & BSU-49, they don’t have the same kinematic effect (or blast radius). As a consequence, aiming has to be very precise for the target to be hit.

Most bombing events can be practised on the range. An event is a planned bomb pass that is standardised with known settings:
• 10° LALD = 10° dive Low Altitude, Low Drag.
• 10° LAHD = 10°dive Low Altitude, Hi Drag.
• 20° LALD = 20° dive Low Altitude, Low Drag.
• 30° DB = 30° Dive Bombing.
• 45° HADB = 45° High Altitude Dive bomb.
• 45° HARB = 45° High Altitude recovery bombing (when recovering above a certain threat altitude).
• STRAFE = Air to Ground Gunnery on the vertical targets.

All those events have their own settings in the following table:

• Base Altitude is the altitude where you should be before turning base. It’s in thousands of feet and be aware it is AGL.
• Base distance is the horizontal range from the target where you should start to turn base. As seen above, the best way to gauge that distance is visually but you van also trick the system by using the CCRP base distance to target. Make sure the steerpoint of interest is the target, select CCRP and check base distance to target in the HUD given in the bottom right of the HUD.
• Base airspeed is self-explanatory it’s the calibrated airspeed you need to be at base.
• PRA is Planned Release altitude. You drop your weapon when you pass through that altitude.
• MRA is Minimum Release Altitude. Don’t drop below that altitude.
• Release airspeed is self explanatory as well: your calibrated drop airspeed.
• %BFL is the distance between the FPM and the target expressed as a percentage of the total CCIP line (from FPM to pipper) 25% BFL means that the FPM is placed 25% of the length of bomb fall line above the target. This info is needed to determine your aim off point( AOP).
• Fuse Arm is the Arming delay for your weapon, which should be set at ramp.
• Bomb Time of flight is self explanatory – if you release at PRA within all settings.
• Foul Altitude is your safety floor. Strikers can not go lower than foul altitude without risking flight safety. Any pilot going under that Foul altitude will be sent RTB directly.
