Notes: Top 5 Mistakes Pilots Make (AOPA seminar Feb 21 2008)
Lesson plan revised 24 February 2008; private pilot instrument.
83% of accidents are due to pilot-related factors
- ‘inevitability’ mindset
- “everyone is bound to have an accident eventually”
- accidents are not inevitable.
- fly the airplane and give yourself options
- ‘get-there-itis’ causes obvious problems
AOPA resources
- mountain flying
- better way to escape imc
#1: Maneuvering flight (33% of total)
- Pilots who put on impromptu airshows or barnstorm
- reckless operation at low altitude
- Traffic pattern
- high power settings
- low altitude
- Low-altitude jobs like crop dusting, photography, pipeline patrol
- It’s difficult to see obstacles at low altitudes
- wire strikes involve 4 times more aircraft than helicopters
- unlit towers – listen to notams!
- Most stall/spin accidents occur on takeoff, not the base-to-final turn
- high power setting and AoA
- lots of rudder to offset turning tendencies
- low altitude
- attempts to return to runway
#2: Weather (14% of total)
- Inadvertent IMC, often due to scud running, causes more than half of wx accidents
- however, 43% of accidents involve IFR pilots.
- 25% break up in flight, prior to impact!
- First priority on encountering poor weather: LAND
- On encountering IMC, use the autopilot to control the aircraft
- 180° turn with heading bug!
- at the least, wings level and full power!
- Know limitations – yours, the aircraft’s, the equipment’s!
- set personal minimums and do not break them
- fly with a CFII in marginal weather to determine comfort level
- DO NOT FLY IN:
- thunderstorms!
- ice!
- heavy turbulence!
- any weather below personal minumums!
- If the weather is bad, there are two choices:
- Don’t take off! If you have,
- Land, anywhere that is available.
- Consider teaching private students to fly a gps approach
- downside: altitudes aren’t included in the hardware
- plates can be confusing in sitting at a desk
#3: Takeoff & climbout
- Highest workload and demand on aircraft occurs during takeoff
- high AoA
- low speed
- high power
- lots of rudder (to deal with latter)
- Priority: keep it flying
- use rudder for limited directional control
- pitch for speed
- stop the roll if not airborne
- land straight ahead (on runway if distance remains) until at least 700 agl
- Do runway length calculations
- leading cause of takeoff accidents is a lack of performance
- add 50% to distances – performance numbers are not gospel
- if runway length <2,500 ft or altitude >2,500 MSL, figure for density altitude
#4: Descent & approach
- Cancel IFR or close VFR flight plans on the ground at the destination
- don’t blindly cancel when ATC asks you to report visual
- Practice instrument approaches all the way to the runway
- consider diverting if you go missed in actual
- Practice crosswind landings
- many accidents occur during the landing roll
- Need more than 30° of bank in the traffic pattern? Go around!
#5: Fuel
- 3 GA pilots a week run out of gas
- plan to land with 1 hr of gas
- if marginal weather, land or divert
