To
Find Flaps 30 V Ref for Weight
1.
Take the weight in thousands over a 100,000lbs
2.
Divide by 2
3.
Add 107
Example
Let's say our weight is 140,000lb's, find the flap 30 V Ref
Weight over 100,000lbs is 40
Divide 40 by 2 to get 20
Add 107 to get V Ref Flap 30
So That's 20+107 That equals 127 Kts IAS ( It's Pretty Close,
Eh!)

Other
Speeds, 727

To
Find Flaps 15 V Ref
use the above procedure and add 122 at item 3 instead
of 107 (increase of 15)
So Flap 15 V Ref is 20+122 = 142 Kts
To
Find Flaps 5 V Ref
Use the above procedure but add 137 at item 3 instead of 107
(increase of 30)
So
Flap 5 V Ref is 20+137 = 157 Kts
To Find Flaps 0 V Ref
Use
the above procedure but add 167 at item 3 instead of 107 (increase
of 60)
So Flap 5 V Ref is 20+167 = 187 Kts

TAKEOFF,
727

Estimation
of Take Off V Speeds
 Flap
15 V2 Speed will be 12 Kts more than V1/VR speed
 Flap
5 speeds should be about 8 kts more than flaps 15 V1/VR speed
 Flap
25 speeds will be about 8 kts less than flaps 15 V1/VR speed
Again
you use the above procedure but add 104 at item 3
Using the same 140,000lb's example
Weight over 100,000lbs is 40
Divide 40 by 2 to get 20
Add 104 to get V Ref Flap 15
So That's 20+104 That equals 124 Kts This is an approximation
of V Ref flaps 40 and V1/VR for flaps 15.
So finishing the example using the above criteria
Flap
15
Flap 5
Flap 25
V1/VR
124
V1/VR+8=132
V1/VR8=116
V2
124+12=136
V2 132+12=144
V2 116+12=128

Climb
Speeds, 727

727200
Best Climb Speed: 1/2 Gross Weight Over 100,000 + 270 = Climb
Speed
Again
the using that 140,000 lb example. 20+ 270=290 Kts
727100
Best Climb Speed: 1/2 Gross Weight Over 100,000 + 280 = Climb
Speed
Again the using that 140,000 lb example. 20+ 270=300 Kts

DECENT,
All 727

Best
Decent Rate
3* the altitude to loose distance to start down (approx 280
kts2500fpm)
Example
FL 350 3*35=105 NM TOD ( Don't forget you may need to slow
down)
Best Decent Gradient
Altitude (FL) = Descent angle then multiply by miles
per min = decent fpm in (100')
Distance (NM)
Example
FL200 Dist 50 NM
200
=Decent angle 4 then * mile per min say (6) = 24 =PO(2,400
fpm)

CRUISE,
727

Initial
Cruise EPR:
To
determine the initial cruise EPR you can use the following formula
to be approximate
Twice
the altitude (FL) +1/2 the Gross Weight over 100,000= Last two digits
of cruise EPR.
Example 140,000lb's at FL33  So 2* 33=66+ (40/2=20)=1.86

LANDING
, 727

To
Find VDP
If
the VDP is not published, take the altitude to descend from the
MDA to TDZE (number in parentheses next to MDA) and move the decimal
point one place to the left. This gives you your time in sec's to
subtract from time to MDA to get time to VDP.
Don't miss the runway its career limiting

Temperature
All & 727

To
Find ISA & TAT
To
Obtain ISA Temp Double the altitude and subtract 15
To Obtain TAT From ISA @ .80M add 30

Meters
Per second to Knots, All

Don't
get clever just double it to get knots. So if some "metric"
twat gives you a "clear to land wind is 230 at 12 meters sec"
it's 24 knots give or take a tad. 3
meters a second is 6 knots, get the idea.

Time
/ Distance, 727

The
first 100 NM will take approx 17 min's time you clean up and get
going, (+/ 2 min, which is what you can cock it up by anyway)

DME
ARC LEAD (Turn Lead Point) ALL

For
DME Arcs lead the arc by one percent of your ground speed. For example
if you ground speed is 220 Kts lead the arc (turn on) by 2.2 NM.
Make sure you get a rate one turn on, Don't mess about at 10 deg
bank).

Approach
Speed Power Setting (30 Flap), 727

As
a general guide set the Fuel Flow around 3500 lbs, (give or take
a bit depending on your weight). This should be close to nail
the required bug speed on approach. (Ballpark Figure). A heavy
200 will need a little more.
