Rules Of Thumb

Question 1

Level attitude

Answer 1

2-3 deg nose up

Question 2

1% pitch up vs power to maintain speed

Answer 2

2.5% N1 = 1/4 knob
+250 pph

Question 3

Gear down or flaps extension per 10 deg, N1 adjust

Answer 3

N1 + 2.5%

Question 4

Descent gradients

Answer 4

Idle clean high 280/.77 3-3.5 deg 2000fpm
Idle clean 250ft/nm 2.5 deg low (250kt) 1250fpm
Gear down 100-200 ft/nm
Speed brakes 400-500ft/nm
Flaps (each 10) 100ft/nm
Power + 3%N1 100ft/nm

Question 5

Speed brakes impact on descent gradient

Answer 5

Approx doubles

Question 6

Thrust for taxi

Answer 6

40-45% 2 knob width
Line inside thigh
Lead with rudder
Beware Swing of wings

Question 7

Rate of descent ; gs and degrees

Answer 7

5/3 * degrees * GS = ROD
2 = 3.3xGS (x3 +10%)
3 = 5xGS (5.2 précise)
4=6.6xGS (x6 + 10%)
5=8.3xGS

Question 8

SRT radius
SRT bank
Lead degrees for arc to radial

Answer 8

Radius (nm) = nm/min / pi
AoB = TAS/10 + 7
Lead degrees = TR x 60/DME

Question 9

TAS from IAS

Answer 9

TAS = IAS + (2% IAS per 1,000ft)
TAS = IAS + FL/2

Question 10

Max range mach number
99% max range (4 Eng)
AoA

Answer 10

M0.76
M0.777
0.27 +/- 0.05

Question 11

Glide / best range descent

Answer 11

M0.76 or IAS charted (approx GW/1000)
1:15 or 3.8 degree… 380ft/nm

Question 12

Descent profile
Clean

Answer 12

Idle ~2000 fpm , 260 ft/nm, 2.5-3 deg
Distance = 3 x Alt
M0.77 -> 31,800
280 KIAS -> 10,000 350 ft/nm 3.5 deg
250 KIAS -> SFC

Question 13

Tactical Descent A
ROD, Angle HI and LOW
Distance to lose 1,000ft

Answer 13

Speedbrake, Idle: 4,300fpm / 540ft/nm / 5 deg
Dist = 2 x Alt (conservative)
M0.8 -> 30,600
300 KIAS -> 10,000 - 800 ft/nm 8 deg
250 KIAS -> SFC

Question 14

Turn radius at 30 AoB
TR for SRT

Answer 14

(Dont seem very helpful)
IMN squared x 10 (best)
(IMN x 10) - 2

Most useful:
(nm/min = IMN x 10 )
SRT TR = nm/min / pi
Approx = TAS / 200 (60pi)

300kts
TR chart low alt DFM = 1.6 nm
Formula = 5/pi = 1.57 or 300/200 = 1.5

Question 15

220klb
Vapp
Vth
Vtd

Answer 15

Vapp = 163kts
Vth = 157kts
Vtd = 147kts

Question 16

Runway required for landing
Ballpark
Normal
Emergency 95% DBF

Answer 16

Non emergency
Min dry 8,000ft
Min wet 9,500ft

Emergency
Min dry 6,000ft
Min wet 8,000ft

Question 17

220k speeds:
20F approach
Pattern
Approach
Threshold

Answer 17

188
187
163
157

Question 18

Increased landing distance (flare and ground) per 1kt extra threshold

Answer 18

+1% (worst case ~ 100ft)
F50!

Question 19

Procedure turn ranges

Answer 19

45/180: 1:15 from start of turn
3xTR + 2 approx 6
80/260 = 3xTR approx 4
