ENDV Technical Air Questions
With Answers
What is viscous hydroplaning? - ANSWER hydroplaning that is most present
on a very smooth surface (rubber coated pavement). creates a thin layer of
water between the tire and surface and will cause the tires to lock up if
anything more than gentle braking is applied
What is the maximum speed in class Charlie within 4nm of the airport? -
ANSWER AIM 3-2-4, at or below 2500ft AGL within 4nm of a primary airport
of class C airspace are, maximum indicated speed is 200 KIAS
What is the cross circle symbol represent in the plan view? - ANSWER airport
reference point ARP
A crew member must breath oxygen above how many feet? - ANSWER When
above FL350 and a crew member leaves his station, above FL410, one crew
member wears it at all times
because we have a quick donning oxygen mask, we don't have to wear it
above FL250 when one person leaves the cockpit

What is your clearance limit when cleared for the approach and then you lose
comms? - ANSWER the published hold on the missed
the maximum intensity and or development of a thunderstorm is during the
mature stage? - ANSWER when rain begins
When do you need an alternate airport? - ANSWER 123 rule. one hour before
,or after your ETA, 2000 ft AGL, and 3 miles of visibility
if its less than that, then it you need an alternate

What Is mach tuck? - ANSWER mach tuck is the nose down pitching
movement an aircraft experiences as it passes its critical mach number (Mcrt)
air reaches speed of sound which makes shock waves, which then pushes the
winds aerodynamic center aft on the wing. causes a loss of lift.
happens on the horizontal stabilizer, lose elevator effectiveness causing the
nose to drop
slow down and try to bring the nose back up and bleed airspeed
What is the critical mach number? - ANSWER when the first molecule of air
reaches the speed of sound on the aircraft. this forms a shockwave that
changes the handling of the plane.
What is the most dangerous type of precipitation? - ANSWER supercooled
water droplets
what is the airway width communication range guaranteed by a MOCA? -
ANSWER 4nm either side of the airway, MOCA only guarantees minimum
obstacle clearance, there is no guaranteed communication. guarantees VOR
reception within 22 miles of VOR
Define V1? - ANSWER V1 is the max speed in the takeoff at which the pilot
must take the first action. (apply brakes, reduce thrust, deploy speed brakes
to stop within accelerate stop distance)/ (V1 is also min speed in takeoff,
following a failure of the critical engine, that the pilot may continue the take
,off and achieve the required altitude above take off surface)
before v1, abort takeoff/after v1, continue takeoff
takeoff decision speed
What is CRM? - ANSWER Crew resource management
using the skills, judgements and strengths of all cabin and cockpit personnel
in all situations. working as a team to get a desired outcome
what is coffin corner? - ANSWER Altitude where Mcrt (critical mach) and Vs
(stall speed), become equal, makes aircraft difficult to control
When is the ILS critical area is in effect? - ANSWER when instrument
approaches are being conducted and vis is less than 2 miles and/or ceiling
800ft or less
runway edge lights are what color (end or runway)? - ANSWER white, on
instrument runways, amber for the last 2000 ft of the runway or last half,
(whichever is shorter)
What does pressing the fire button do? - ANSWER activates shutoff valves
for fuel and hydraulics, trips generator off via generator relay, arms the fire
bottle
What is the max take off weight? - ANSWER CRJ700: 75,000lbs
CRJ900: 84,500lbs
What is the DH? - ANSWER the altitude in AGL at which a decision must be
made to continue or not on an approach (IlS, or with vertical guidance)
What would you do if you hear a loud band and lose power after V1 with
over half an 11,000ft runway left? - ANSWER Continue takeoff and treat it as
, an in air emergency
What would you do if the captain continued below minimums? - ANSWER
call out "below mins", and ask him if he has the runway in sight, if he
doesn't, then call a missed approach and go around
What is exemption 3585? - ANSWER allows operation when forecasts
conditional remarks are below dispatch minimums. the main body of the
forecast must be above the dispatch minimums. need a second alternate,
need weather updates
centerline runway lights are what colors? - ANSWER white, then the last
2000/3000 feet alternate white and red, then last 1000 red.
How do you counteract a dutch roll? - ANSWER yaw damper, or opposite
control inputs to counteract
What type aircraft is susceptible to dutch roll? - ANSWER swept wing aircraft
What is the standard temp lapse rate? - ANSWER 2 degrees C for each 1000
feet increase in altitude
what do the circles on the airport diagram mean (10-9)? - ANSWER hot spot:
a runway safety related problem or intersection point on an airport, typically
more complex or confusing than most areas
Where would we find the T/O minimums (10-9) - ANSWER T/O minimums
are typically on the back of a airport diagram in jep charts
on faa, they are in the procedures of the airport in foreflight
What does HS circle (runway incursion hot spot) mean on an airport
diagram? (10-9) - ANSWER hot spot #, use the number and the front of the
