Hi all,

I'm study how can I fly an HADB but I have some question...

What is the range of release altitude for a HADB? From 10ANG to 20ANG?
In MCH Vol.5 the HADB is defined for Dive angle > 30° and relese altitude medium or high.

Usually when I fly a Dive attack I have the target in the FOV of my HUD and I perform an attack using CCIP but if I plan an HADB the target is outside my HUD FOV. Is it normal? In this case I must use CCRP delivery.

That is an example of my attack:

- Dive 40°
- Release Speed 450 Kts (CAS)
- Release Height 14000 ft
- Tracking Time 10 sec
- Ingress Speed 350 Kts (CAS)
- Pulling G's 4 g
- Turn to Target Left with Angle Off of 60°
- Ingress Alt (result of precedent data) 23821 ft

The SDFP is (tan-1 Rel.alt/BR) - 40° = (tan-1 14000/8738) - 40° = 24°

I have the target at 64° and AimOff at 40° (Aim Off Distance 7947 ft).

Is there any error?

Is possible that I don't have understand what is the HADB...

Thank's for your time.

Regards

Salute!

1) If you still have DTOS, use it!!

2) The pipper in CCIP should be "caged" below the FPM someplace when the actual impact point is outside of the FOV of the HUD or outside current bomb range. In this case, fly the pipper to the tgt, then press and hold the pickle button and follow left-right steering (same as DTOS).

3) Use the top of the HUD to help you get lined up, then try #1 or #2 above.

later,

Hi Gums,

thank's for your reply.

Actually I don't have problem for release the weapon, I can use DTOS, or CCIP like your suggest, or use CCRP because I have already the coordinates of the targed stored as my target steerpoint. For align I follow the steering line.

I would like to know in HADB usually, what is the Dive Angle and Release Altitude that you use? That is for plan a training. Can be correct 40° Dive and Release at 14000?
In Multi Command Handbook Vol.5 I can read that HADB is for Dive > 30° and I think that 40° is correct, but release altitude?
I want to perform a release above enemy ground defence life SA7 and SA14...

Can you help me?

Thank's in advance.

Dear,

The question is ~10 years ago. I am also interesting on the HADB. So i have found your question at this time.
In your description that when target is in the HUD, you perform the attack, i think u dive early.
If the dive angle is 40degs, u can't see the target in the HUD because it is below your plane. The horizontal line below MFD is ~30degs so 40degs is more below.
The lead distance indicating when u roll and dive is important. The rough calculation (350KCAS @24k') is ~4.5nm from the target.
Try ur dive around 4.5nm that it is horizontal not slant distance.

Thanks,

Looking back through my old yellowed paperwork:

Standard patterns "back in the day" were 10 LAB, 20 LALD, 30 DB, and 45 HADB (not 40). Time on final was 3-5 secs. (Longer than 5 secs was a foul.) The following numbers are for an F-16A with BDU-33. All airspeeds are KCAS. All altitudes are AGL. Temp is 23C. Pressure altitude is 1000'. GW is 21000 lbs.


45 HADB:

MILS= 167 (SUU-20) 158 (TER)

Roll in= 12950' (vertical) 10400' (horizontal (base leg))

Altitude loss on roll-in= 2000'

Track altitude= 10950'

Track airspeed= 350

Track AOD / IPP= 2100 / 41 (SUU) 2000 / 38 (TER)

Release altitude= 8000'

Release airspeed= 450

Wind correction= 1.5mils per knot head-tail 20' per knot crosswind

Altitude loss after release (4G in 2 secs)= 2973'

Ground clearance after recovery= 5027

Minimum altitude (foul)= 4500
F-4C/D, F-16A/B/C/D, 727, DC-10, MD-80, A321

Thanks for RL information which is valuable. ; Could u let me get the elevation of target? (i guess ~1500')
