Dear all,
Another mission is ready. This mission is for a bomb training on the Chikdo field. The mission is similar to the default BMS TE mission on Kotar. I tweaked something and changed to Chikdo. There are two targets and the real target in this mission is a circular target on the left side (see the falcon-bms map).
F16 carries 2xA9 2xA120 12xBDU33DB 2xT370 ALG184. The mission starts just before waypoint to Chikdo. The initial gross weight is 35k lbs and DI of 168. It starts in the middle of the mission, when you starts the mission, the amount of fuel was consumed around 4000 lbs. The mission file can download in here . The circular target is assigned on W11. Change the waypoint and fly to the target. You can test various bombing techniques, level, dive bomb, loft bomb, , manual bomb, and etc. Here, the following youtube shows high altitude dive bomb (HADB).
HADB stands for high altitude dive bomb. It is defined for dive angle over 30 degrees and release altitude is medium or high (over 10k’ ASL, above surface level). This has some advantages compared to low altitude loft bombing (LALB) or level bombing. It is designed for in a high threat environment and performs a bomb release above enemy ground defence system, such as AAA, MANPAD and SHORAD etc. If target is surrounded by static SAMs, the approach is not good. Another advantage is better for target recognition and bomb efficiency. Higher dive angles give a better accuracy and higher impact angle which is effective on the flat targets, such as a harden ‘flat’ bunker, etc. Downside is that high angle loses altitude quickly so that it’s hard to align target. Thus this is for better fixed target not moving targets.
To perform properly, you understand Z-diagram that is presentations of pattern and weaponeering information. The following is an example for HADB Z-diagram. It consists of various parameters, A/S: airspeed at approach (top: 400 KCAS) and release (bottom: 534 KCAS), ALT: altitude at approach (top: 20k ft) and release (bottom: 13k ft), ACD: attack cone distance (roll in toward target: 3.4) in nm, FPA: flight path angle (dive angle: 45 degree), SA: sight angle (140 mil-radian: 8 degree) in mil-radian (mr) summing of SD (sight depression) and AOA, TOF: time of bomb flight, RPM: engine round per minute in %, AOD: aim off distance in feet and angle in degree (same as SD), and Zmin: minimum release firing altitude.

The following table shows the release parameters (TAS, Alt, and Alpha), TbF (Time of bomb fall), miss distance (Err), and MR (milradian for miss distance at the release) in the youtube. The CEP which represents 50% of hit is ~82 ft.

If you send your acmi file saving the training mission to me, I can calculate these parameters, in particular CEP for you and you can know your exact CEP and error.
