Question 2

St max

Answer 2

Max Speed target (Maxima velocidad del blanco)

Question 3

Im

Answer 3

Angule of the bow AOB (Angulo en la proa)

Question 4

So

Answer 4

Speed Own (Velocidad propia)

Question 5

Bm

Answer 5

Bearing (Angulo de la proa propio)

Question 6

PD

Answer 6

Periscope Deep (Profundidad de periscopio)

Question 7

SD

Answer 7

Security Deep (Profundidad de seguridad)

Question 8

GDC

Answer 8

Go Deep Circule (Circulo para ir a profundidad).

Question 9

GDR

Answer 9

Go deep Range (Distancia para ir a profundidad)

GDR [yds]= ((Ve + Vdmax)/3))*100

Question 10

LI

Answer 10

Looking Interval (Intervalo de Observación)

LI [min] = (Rm / GDR) - 1

Question 11

LI AAL

Answer 11

Looking interval at all (Intervalo de observación alrededor)

LI AAL = (Rm,max / GDR) - 1

Question 12

Rm

Answer 12

Range (Distancia al contacto)

Question 13

STANDARD GDR

Fisher Vessel (FV) (8kn)

Answer 13

500 yardas

Question 14

STANDARD GDR

Small Motor Vessel (SMV) (17 kn)

Answer 14

800 yardas

Question 15

STANDARD GDR

Larga Motor Vessel (LMV)

Answer 15

1000 yardas

Question 16

STANDARD GDR

Ferry

Answer 16

1200 yardas

Question 17

STANDARD GDR

Fast Patrol Boat (FPB)

Answer 17

1500 yardas

Question 18

Periscope Rules in Deep Waters

Worst case assumptions

Answer 18

Vd = Vd max
Im = 0
Ve = 7 kn
Bm = 0
PD - > SD = 1 min

Question 19

Periscope rules in shallow waters

Worst case assumptions

Answer 19

Vd = Vd max
Im = 0
Ve = 7 kn
Bm = 0
&
NO SAFE DEAPTH (but: Adapted Safe Depth (ASD))

Question 20

Extended Go Deep Circule

Answer 20

eGDR [yds] = x * ((Ve + Vd max)/3)*100)

X is at least 2 and specified by CO!

Question 21

T1T2 Procedure

Answer 21

• Without reduction of GDR : T1=T2
• Return to PD at: T2 - Time to go PD
• During the whole use of this procedure target speed and course must be unchanged
• No other LI collapses

Question 22

German Periscope Philosophy

Covert and Safe

Answer 22

• Geography
• Traffic density
• Sub Safety relies on one individual
• Stay at PD as long as possible

Question 23

PEREX

Assessment criterias

Answer 23

• Procedures
• Teamwork
• Picture Compilation
• Task Fulfillment
• Leadership
• Boat Handling

Question 24

DOT (Distance to Track)

Answer 24

DOT = Rm * Sin Im

Question 25

Rules of sin result

Answer 25

α < 30 ➡️ SIN α = (α/100) + 0,1

α < 30 ➡️ SIN α = 0,5

30 < α < 70 ➡️ SIN α = (α/100) + 0,2

α < 70 ➡️ SIN α = 1

Question 26

Looking Around report (END)

Answer 26

• Weather Conditions in the area
• Maximo Periscope Range view
• in the case that we don’t have contacta in the area, has to be determined and Fast Contact waiting in the area in order to has a GDR and the LI AAL.
• If there are contacts, is necessary report identification or kind vessel, Bearing, AOB, Distance and LI. Also have to be determined with contact has the priority (Close contact).
