What are the differences between airbrakes on the top side of jet aircraft (like on the F-15) compared to those on the lower side (like on the A-7), in terms of effectiveness and pitching when they are deployed?

F-15 lands with deployed airbrake From Wikipedia.

A-7 with deployed airbrake From Reddit.

Would pitch authority be better in one than the other?


Since airbrakes are frequently used during landing, putting them underneath the fuselage could create a ground clearance problem.

Putting brakes on the top only would create a pitch-up tendency when they are deployed. This is countered automatically by the Fly-By-Wire flight controls, so no correction is necessary for the pilot.

    $\begingroup$ I thought that the Korea-era fighters like the Sabre were the closest we got to bottom-mounted airbrakes... then I remembered the A-7... and added it to OP's question because more people need to see the flying ironing board. $\endgroup$ – AEhere supports Monica Sep 23 '19 at 9:49
  • $\begingroup$ The F-4 has airbrakes under the wings and no clearance problem. $\endgroup$ – George Geo Sep 23 '19 at 11:07

    $\begingroup$ The mirage F1 also has airbrakes on th lower part of the fuselage (picture) $\endgroup$ – Manu H Sep 23 '19 at 15:46
  • $\begingroup$ The A-6 and EA-6B had them on the wingtips... $\endgroup$ – Michael Hall Dec 28 '19 at 20:57
