Abbrevations Flashcards
RCR
Runway condition rating
Measure rwy friction coefficient
Assumed
Dry - 23
Wet any - 12
Ice - 5
RVSM
Reduced vertical separation min
Above Fl290
Reduced to 1000ft
RVR
Rwy visual range
How far can you see on the rwy
Low vis = RVR less than 2000m
ETP
Equal time points
Equal time to go between 2 suitable alternate airfields
PNR
Point of no return
Max distance you can travel and return with safe fuel reserves:
Alternate fuel + 15,000 lbs (final + app)
TOLD
Take off and landing data
w/o ER
With out extended range
WAP
Warning annunciating pannel
AFCS
Automatics flight control system
SC/EFC
Spoiler control / electronic flap computers

Shows n1 n2 EPR EGT
MAC
Mean areodymanic chord
Used as percentage reference for cofG loading
Frontside backside
frontside
-conventional aircraft, add power add speed
-pitch affects flight path
Backside (flaps 1/2 or more)
- thrust effects flight path
- pitch effects speed
PACAH
Pitch Attitude command/altitude hold
On the EFCS
Used for small changes in airspeed
DLC
Direct lift control
Used for large adjustments in flight path without having to have large throttle changes and risk a stall
AGS
Automatic ground spoiler
PRCAH RRCAH
Pitch rate command attitude hold
Roll rate command attitude hold
