Lofte 7

[rmiles]

I've always wondered what you do with your aircraft/bombsight after you consult Lofte 7? (Prove me wrong, but I think you have to use the true airspeed and altitude on Lofte 7 on the bombsight)

So, and some point, this should get me level bombing frequently!

The lotfe7 is installed in the He111 and Ju88. These planes require you to input TAS.

The Blenheim is more accurate with IAS.

Don't forget to figure out the home base and target altitudes.


Good luck and have fun.

What's TAS? I know it means tool-assisted speedrun, but what do I have to precisely use it for?

[PreyStalker]

I've been messing around in the HE 111 too, offline only. Change of pace from my usual 109.

I think TAS is True Air Speed. There's a chart somewhere, in the manual I think. It gives you TAS for a given altitude and IAS reading.

DRock, why do I need my home base altitude ?

You mean this LOTFE 7?

http://theairtacticalassaultgroup.com/utils/lotfe7.html

You use the TAS (True Air Speed) obtained there in the He 111 and Ju 88 Lotfe bombsight adjusts.

Some guys don't use this IAS (Indicated Air Speep to TAS) converter tool but a table based in their game observations. They say that target altitude is not modeled in bombsight. calculations

UAI_Skab in Russian section of this forum ( Google translation):

Following table itself speed and angular

Speed - Angle (for bombsight)

160 9
170 10
180 11
190 12
200 13
210 14
220 15
230 16
240 17
250 18
260 19
270 20
280 21
290 22
300 23
310 24
320 25
330 26
340 27


"This table is designed to drop bomb 8 * 250 SC bombs
If you load bombs 32 * 50 SC set two degrees less than the table.
For example if the speed of 200KM/H then the angle is 11... etc.
Drop angle and constant speed is good by the fact that you can make in a single flight separate discharges for several purposes ..
When operating with bombsight automatic mode RESEASE ON this is impossible."

In the same way use real life tables and IAS/TAS formulas or E6B/DR-2 "flight computer" don't work very well in "Dr.Who'legs World".

DRock, why do I need my home base altitude ?

Accuracy.

The airfield you take off from and the target you are hitting will most likely not be at the same altitude above sea level. This should be considered when inputting current altitude into Lotfe7.

Wind will also have an effect. Using the slip may be required when bombing in a strong crosswind.

there is also a simplified way to use the LOFTE 7 sight that works well and you only need a number or 2 so you don't have to look at the chart all the time after you do it a while them you can go back to the chart if you need too .

Well, let's say we were taking off from Theville to bomb Tangmere, what would I have to set in Lofte 7? (And how does elevation work?)

You could a lot worse that reading up on the bombsight in chucks guides.

I'm not at all saying don't post questions. What I mean is that there is a lot of other really useful related info in the guides to help you too.

To answer you though the elevation is the height of the item above sea level. Since your altimeter is I think set to sea level by default you only need to worry about the target elevation. I'd that's say 150m then you take that away from the overall bombing height. So if you were at 3000m you take away the 150 in the alt of the loft 7 to read 2850. Then it's down to checking height and ias and adjusting taking into account the calculation to convert ias to tas. Finally there's the effect of wind to adjust for.

There is no real magic formula I don't think. It's experienced based. Pretty much the only thing to say it that the higher you bomb from the less effect target elevation will have and the slightly more spread out your hits will be.

The bombsights in CLOD do not work perfectly so there are 2 ways to deal with this.

Using your example, you spawn at Theville, the altimeter shows your current elevation. All missions are at standard barometric pressure, so it needs no adjustment. From now on you can skip this step.

In the real world you would have to adjust your altimeter to the known airfield elevation which would then give the current local barometric pressure. You would then have to know target local barometric pressure for the altimeter to remain correct at the target. Again you can skip this step.

Method 1. Once at Tangmere and at say 6000 meters, set your bombsight alt minus elevation, say 100 m (not the actual elevation as not on gaming comp) so 5900. Set TAS. I use 400 km/h as starting point. While in bombsight set your crosshairs to the aimimg point, taking in wind to account, and start the bomsight automation. Keep the crosshairs stationary by increasing/decreasing bombsight speed throughout the bomb run until they drop, which should be at ~22 deg at this alt.

Method 2. Again set target alt (5900m) and set TAS. We are going 300 IAS so by my i- phone app we are going 418.1km/h TAS, so set 420 in to the bombsight. Set crosshairs on target and start bombsight automation. The crosshairs will not be stationary. Keep them on target by maunaully using the bombsight up/down keys until the bombs drop.

I use method 1. So takeoff, set bombing alt minus target elevation (5900), set bombsight speed to 400, adjust bombsight speed to keep crosshairs stationary.

In 88, if using salvo mode, your aim point should be at the 1/4 mark from the bottom of the bomb spread, as most bombs hit after your aim point.

In the 111 and using 8 x 250s, your aimpoint should be ~where you want the last bomb to hit, all bombs will drop before your aimpoint.

adjust bombsight speed to keep crosshairs stationary.

This has always confused me. Do you adjust bombsight speed or altitude to keep the crosshairs stationary?

All things to consider if level bombing from altitude:

-Bombsight speed (convert IAS to TAS if using Lotfe7)

-bombsight altitude (consider home base/target altitude difference)

-aim (Lotfe7 is adjusted with Sight Distance)

-wind speed and direction

-bomb spread with higher altitudes

-bomb mass (50kg and 500kgs drops vary)

-level plane before drop (most important)


The more you consider, the more accurate you become.


Good luck!

It is a really good tutorial for the HE 111....

Very true! Even in German NadaZero sounds very German A very calm higher German accent. The perfect voice for an instructor.

Thanks, but I have enough trouble already just loading my cannons with ShpringShprongBrandSprandPanz.........patrona !
